+
+###################
+Deprecation warning
+###################
+
+This library is still missing some features (including full Unicode
+support), and does not work on some of the newest compiler versions.
+Therefore, please prefer to use the
+`WhatWG URL implementation`_ that
+is intended to supersede this library.
+
+.. _`WhatWG URL implementation`: https://github.com/cpp-netlib/url

+This project contains the source code that was originally meant to
+track the proposal for a C++ URI at
+http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n3975.html
+
+This package provides:
+
+ * A ``network::uri`` class that implements a generic URI parser,
+ compatible with `RFC 3986`_ and `RFC 3987`_
+ * Accessors to the underlying URI parts
+ * A range-compatible interface
+ * Methods to normalize and compare URIs
+ * Percent encoding and decoding functions
+ * A URI builder to build consistent URIs from parts, including
+ case, percent encoding and path normalization
+
+.. _`RFC 3986`: http://tools.ietf.org/html/rfc3986
+.. _`RFC 3987`: http://tools.ietf.org/html/rfc3987

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your patches! Before we can take them, we have to jump a
+couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement
+(CLA).
+
+* If you are an individual writing original source code and you're sure you
+ own the intellectual property, then you'll need to sign an
+ [individual CLA](https://developers.google.com/open-source/cla/individual).
+* If you work for a company that wants to allow you to contribute your work,
+ then you'll need to sign a
+ [corporate CLA](https://developers.google.com/open-source/cla/corporate).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Are you a Googler?
+
+If you are a Googler, please make an attempt to submit an internal change rather
+than a GitHub Pull Request. If you are not able to submit an internal change a
+PR is acceptable as an alternative.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the
+ [issue tracker](https://github.com/google/googletest/issues).
+2. Please don't mix more than one logical change per submittal, because it
+ makes the history hard to follow. If you want to make a change that doesn't
+ have a corresponding issue in the issue tracker, please create one.
+3. Also, coordinate with team members that are listed on the issue in question.
+ This ensures that work isn't being duplicated and communicating your plan
+ early also generally leads to better patches.
+4. If your proposed change is accepted, and you haven't already done so, sign a
+ Contributor License Agreement
+ ([see details above](#contributor-license-agreements)).
+5. Fork the desired repo, develop and test your code changes.
+6. Ensure that your code adheres to the existing style in the sample to which
+ you are contributing.
+7. Ensure that your code has an appropriate set of unit tests which all pass.
+8. Submit a pull request.
+
+## The Google Test and Google Mock Communities
+
+The Google Test community exists primarily through the
+[discussion group](http://groups.google.com/group/googletestframework) and the
+GitHub repository. Likewise, the Google Mock community exists primarily through
+their own [discussion group](http://groups.google.com/group/googlemock). You are
+definitely encouraged to contribute to the discussion and you can also help us
+to keep the effectiveness of the group high by following and promoting the
+guidelines listed here.
+
+### Please Be Friendly
+
+Showing courtesy and respect to others is a vital part of the Google culture,
+and we strongly encourage everyone participating in Google Test development to
+join us in accepting nothing less. Of course, being courteous is not the same as
+failing to constructively disagree with each other, but it does mean that we
+should be respectful of each other when enumerating the 42 technical reasons
+that a particular proposal may not be the best choice. There's never a reason to
+be antagonistic or dismissive toward anyone who is sincerely trying to
+contribute to a discussion.
+
+Sure, C++ testing is serious business and all that, but it's also a lot of fun.
+Let's keep it that way. Let's strive to be one of the friendliest communities in
+all of open source.
+
+As always, discuss Google Test in the official GoogleTest discussion group. You
+don't have to actually submit code in order to sign up. Your participation
+itself is a valuable contribution.
+
+## Style
+
+To keep the source consistent, readable, diffable and easy to merge, we use a
+fairly rigid coding style, as defined by the
+[google-styleguide](https://github.com/google/styleguide) project. All patches
+will be expected to conform to the style outlined
+[here](https://google.github.io/styleguide/cppguide.html). Use
+[.clang-format](https://github.com/google/googletest/blob/master/.clang-format)
+to check your formatting.
+
+## Requirements for Contributors
+
+If you plan to contribute a patch, you need to build Google Test, Google Mock,
+and their own tests from a git checkout, which has further requirements:
+
+* [Python](https://www.python.org/) v2.3 or newer (for running some of the
+ tests and re-generating certain source files from templates)
+* [CMake](https://cmake.org/) v2.8.12 or newer
+
+## Developing Google Test and Google Mock
+
+This section discusses how to make your own changes to the Google Test project.
+
+### Testing Google Test and Google Mock Themselves
+
+To make sure your changes work as intended and don't break existing
+functionality, you'll want to compile and run Google Test and GoogleMock's own
+tests. For that you can use CMake:
+
+ mkdir mybuild
+ cd mybuild
+ cmake -Dgtest_build_tests=ON -Dgmock_build_tests=ON ${GTEST_REPO_DIR}
+
+To choose between building only Google Test or Google Mock, you may modify your
+cmake command to be one of each
+
+ cmake -Dgtest_build_tests=ON ${GTEST_DIR} # sets up Google Test tests
+ cmake -Dgmock_build_tests=ON ${GMOCK_DIR} # sets up Google Mock tests
+
+Make sure you have Python installed, as some of Google Test's tests are written
+in Python. If the cmake command complains about not being able to find Python
+(`Could NOT find PythonInterp (missing: PYTHON_EXECUTABLE)`), try telling it
+explicitly where your Python executable can be found:
+
+ cmake -DPYTHON_EXECUTABLE=path/to/python ...
+
+Next, you can build Google Test and / or Google Mock and all desired tests. On
+\*nix, this is usually done by
+
+ make
+
+To run the tests, do
+
+ make test
+
+All tests should pass.

+# GoogleTest
+
+### Announcements
+
+#### Live at Head
+
+GoogleTest now follows the
+[Abseil Live at Head philosophy](https://abseil.io/about/philosophy#upgrade-support).
+We recommend using the latest commit in the `main` branch in your projects.
+
+#### Documentation Updates
+
+Our documentation is now live on GitHub Pages at
+https://google.github.io/googletest/. We recommend browsing the documentation on
+GitHub Pages rather than directly in the repository.
+
+#### Release 1.11.0
+
+[Release 1.11.0](https://github.com/google/googletest/releases/tag/release-1.11.0)
+is now available.
+
+#### Coming Soon
+
+* We are planning to take a dependency on
+ [Abseil](https://github.com/abseil/abseil-cpp).
+* More documentation improvements are planned.
+
+## Welcome to **GoogleTest**, Google's C++ test framework!
+
+This repository is a merger of the formerly separate GoogleTest and GoogleMock
+projects. These were so closely related that it makes sense to maintain and
+release them together.
+
+### Getting Started
+
+See the [GoogleTest User's Guide](https://google.github.io/googletest/) for
+documentation. We recommend starting with the
+[GoogleTest Primer](https://google.github.io/googletest/primer.html).
+
+More information about building GoogleTest can be found at
+[googletest/README.md](googletest/README.md).
+
+## Features
+
+* An [xUnit](https://en.wikipedia.org/wiki/XUnit) test framework.
+* Test discovery.
+* A rich set of assertions.
+* User-defined assertions.
+* Death tests.
+* Fatal and non-fatal failures.
+* Value-parameterized tests.
+* Type-parameterized tests.
+* Various options for running the tests.
+* XML test report generation.
+
+## Supported Platforms
+
+GoogleTest requires a codebase and compiler compliant with the C++11 standard or
+newer.
+
+The GoogleTest code is officially supported on the following platforms.
+Operating systems or tools not listed below are community-supported. For
+community-supported platforms, patches that do not complicate the code may be
+considered.
+
+If you notice any problems on your platform, please file an issue on the
+[GoogleTest GitHub Issue Tracker](https://github.com/google/googletest/issues).
+Pull requests containing fixes are welcome!
+
+### Operating Systems
+
+* Linux
+* macOS
+* Windows
+
+### Compilers
+
+* gcc 5.0+
+* clang 5.0+
+* MSVC 2015+
+
+**macOS users:** Xcode 9.3+ provides clang 5.0+.
+
+### Build Systems
+
+* [Bazel](https://bazel.build/)
+* [CMake](https://cmake.org/)
+
+**Note:** Bazel is the build system used by the team internally and in tests.
+CMake is supported on a best-effort basis and by the community.
+
+## Who Is Using GoogleTest?
+
+In addition to many internal projects at Google, GoogleTest is also used by the
+following notable projects:
+
+* The [Chromium projects](http://www.chromium.org/) (behind the Chrome browser
+ and Chrome OS).
+* The [LLVM](http://llvm.org/) compiler.
+* [Protocol Buffers](https://github.com/google/protobuf), Google's data
+ interchange format.
+* The [OpenCV](http://opencv.org/) computer vision library.
+
+## Related Open Source Projects

+[GTest Runner](https://github.com/nholthaus/gtest-runner) is a Qt5 based
+automated test-runner and Graphical User Interface with powerful features for
+Windows and Linux platforms.
+
+[GoogleTest UI](https://github.com/ospector/gtest-gbar) is a test runner that
+runs your test binary, allows you to track its progress via a progress bar, and
+displays a list of test failures. Clicking on one shows failure text. GoogleTest
+UI is written in C#.
+
+[GTest TAP Listener](https://github.com/kinow/gtest-tap-listener) is an event
+listener for GoogleTest that implements the
+[TAP protocol](https://en.wikipedia.org/wiki/Test_Anything_Protocol) for test
+result output. If your test runner understands TAP, you may find it useful.
+
+[gtest-parallel](https://github.com/google/gtest-parallel) is a test runner that
+runs tests from your binary in parallel to provide significant speed-up.

+# Advanced googletest Topics
+
+## Introduction
+
+Now that you have read the [googletest Primer](primer.md) and learned how to
+write tests using googletest, it's time to learn some new tricks. This document
+will show you more assertions as well as how to construct complex failure
+messages, propagate fatal failures, reuse and speed up your test fixtures, and
+use various flags with your tests.
+
+## More Assertions
+
+This section covers some less frequently used, but still significant,
+assertions.
+
+### Explicit Success and Failure
+
+See [Explicit Success and Failure](reference/assertions.md#success-failure) in
+the Assertions Reference.
+
+### Exception Assertions
+
+See [Exception Assertions](reference/assertions.md#exceptions) in the Assertions
+Reference.
+
+### Predicate Assertions for Better Error Messages
+
+Even though googletest has a rich set of assertions, they can never be complete,
+as it's impossible (nor a good idea) to anticipate all scenarios a user might
+run into. Therefore, sometimes a user has to use `EXPECT_TRUE()` to check a
+complex expression, for lack of a better macro. This has the problem of not
+showing you the values of the parts of the expression, making it hard to
+understand what went wrong. As a workaround, some users choose to construct the
+failure message by themselves, streaming it into `EXPECT_TRUE()`. However, this
+is awkward especially when the expression has side-effects or is expensive to
+evaluate.
+
+googletest gives you three different options to solve this problem:
+
+#### Using an Existing Boolean Function
+
+If you already have a function or functor that returns `bool` (or a type that
+can be implicitly converted to `bool`), you can use it in a *predicate
+assertion* to get the function arguments printed for free. See
+[`EXPECT_PRED*`](reference/assertions.md#EXPECT_PRED) in the Assertions
+Reference for details.
+
+#### Using a Function That Returns an AssertionResult
+
+While `EXPECT_PRED*()` and friends are handy for a quick job, the syntax is not
+satisfactory: you have to use different macros for different arities, and it
+feels more like Lisp than C++. The `::testing::AssertionResult` class solves
+this problem.
+
+An `AssertionResult` object represents the result of an assertion (whether it's
+a success or a failure, and an associated message). You can create an
+`AssertionResult` using one of these factory functions:
+
+```c++
+namespace testing {
+
+// Returns an AssertionResult object to indicate that an assertion has
+// succeeded.
+AssertionResult AssertionSuccess();
+
+// Returns an AssertionResult object to indicate that an assertion has
+// failed.
+AssertionResult AssertionFailure();
+
+}
+```
+
+You can then use the `<<` operator to stream messages to the `AssertionResult`
+object.
+
+To provide more readable messages in Boolean assertions (e.g. `EXPECT_TRUE()`),
+write a predicate function that returns `AssertionResult` instead of `bool`. For
+example, if you define `IsEven()` as:
+
+```c++
+testing::AssertionResult IsEven(int n) {
+ if ((n % 2) == 0)
+ return testing::AssertionSuccess();
+ else
+ return testing::AssertionFailure() << n << " is odd";
+}
+```
+
+instead of:
+
+```c++
+bool IsEven(int n) {
+ return (n % 2) == 0;
+}
+```
+
+the failed assertion `EXPECT_TRUE(IsEven(Fib(4)))` will print:
+
+```none
+Value of: IsEven(Fib(4))
+ Actual: false (3 is odd)
+Expected: true
+```
+
+instead of a more opaque
+
+```none
+Value of: IsEven(Fib(4))
+ Actual: false
+Expected: true
+```
+
+If you want informative messages in `EXPECT_FALSE` and `ASSERT_FALSE` as well
+(one third of Boolean assertions in the Google code base are negative ones), and
+are fine with making the predicate slower in the success case, you can supply a
+success message:
+
+```c++
+testing::AssertionResult IsEven(int n) {
+ if ((n % 2) == 0)
+ return testing::AssertionSuccess() << n << " is even";
+ else
+ return testing::AssertionFailure() << n << " is odd";
+}
+```
+
+Then the statement `EXPECT_FALSE(IsEven(Fib(6)))` will print
+
+```none
+ Value of: IsEven(Fib(6))
+ Actual: true (8 is even)
+ Expected: false
+```
+
+#### Using a Predicate-Formatter
+
+If you find the default message generated by
+[`EXPECT_PRED*`](reference/assertions.md#EXPECT_PRED) and
+[`EXPECT_TRUE`](reference/assertions.md#EXPECT_TRUE) unsatisfactory, or some
+arguments to your predicate do not support streaming to `ostream`, you can
+instead use *predicate-formatter assertions* to *fully* customize how the
+message is formatted. See
+[`EXPECT_PRED_FORMAT*`](reference/assertions.md#EXPECT_PRED_FORMAT) in the
+Assertions Reference for details.
+
+### Floating-Point Comparison
+
+See [Floating-Point Comparison](reference/assertions.md#floating-point) in the
+Assertions Reference.
+
+#### Floating-Point Predicate-Format Functions
+
+Some floating-point operations are useful, but not that often used. In order to
+avoid an explosion of new macros, we provide them as predicate-format functions
+that can be used in the predicate assertion macro
+[`EXPECT_PRED_FORMAT2`](reference/assertions.md#EXPECT_PRED_FORMAT), for
+example:
+
+```c++
+using ::testing::FloatLE;
+using ::testing::DoubleLE;
+...
+EXPECT_PRED_FORMAT2(FloatLE, val1, val2);
+EXPECT_PRED_FORMAT2(DoubleLE, val1, val2);
+```
+
+The above code verifies that `val1` is less than, or approximately equal to,
+`val2`.
+
+### Asserting Using gMock Matchers
+
+See [`EXPECT_THAT`](reference/assertions.md#EXPECT_THAT) in the Assertions
+Reference.
+
+### More String Assertions
+
+(Please read the [previous](#asserting-using-gmock-matchers) section first if
+you haven't.)
+
+You can use the gMock [string matchers](reference/matchers.md#string-matchers)
+with [`EXPECT_THAT`](reference/assertions.md#EXPECT_THAT) to do more string
+comparison tricks (sub-string, prefix, suffix, regular expression, and etc). For
+example,
+
+```c++
+using ::testing::HasSubstr;
+using ::testing::MatchesRegex;
+...
+ ASSERT_THAT(foo_string, HasSubstr("needle"));
+ EXPECT_THAT(bar_string, MatchesRegex("\\w*\\d+"));
+```
+
+### Windows HRESULT assertions
+
+See [Windows HRESULT Assertions](reference/assertions.md#HRESULT) in the
+Assertions Reference.
+
+### Type Assertions
+
+You can call the function
+
+```c++
+::testing::StaticAssertTypeEq<T1, T2>();
+```
+
+to assert that types `T1` and `T2` are the same. The function does nothing if
+the assertion is satisfied. If the types are different, the function call will
+fail to compile, the compiler error message will say that `T1 and T2 are not the
+same type` and most likely (depending on the compiler) show you the actual
+values of `T1` and `T2`. This is mainly useful inside template code.
+
+**Caveat**: When used inside a member function of a class template or a function
+template, `StaticAssertTypeEq<T1, T2>()` is effective only if the function is
+instantiated. For example, given:
+
+```c++
+template <typename T> class Foo {
+ public:
+ void Bar() { testing::StaticAssertTypeEq<int, T>(); }
+};
+```
+
+the code:
+
+```c++
+void Test1() { Foo<bool> foo; }
+```
+
+will not generate a compiler error, as `Foo<bool>::Bar()` is never actually
+instantiated. Instead, you need:
+
+```c++
+void Test2() { Foo<bool> foo; foo.Bar(); }
+```
+
+to cause a compiler error.
+
+### Assertion Placement
+
+You can use assertions in any C++ function. In particular, it doesn't have to be
+a method of the test fixture class. The one constraint is that assertions that
+generate a fatal failure (`FAIL*` and `ASSERT_*`) can only be used in
+void-returning functions. This is a consequence of Google's not using
+exceptions. By placing it in a non-void function you'll get a confusing compile
+error like `"error: void value not ignored as it ought to be"` or `"cannot
+initialize return object of type 'bool' with an rvalue of type 'void'"` or
+`"error: no viable conversion from 'void' to 'string'"`.
+
+If you need to use fatal assertions in a function that returns non-void, one
+option is to make the function return the value in an out parameter instead. For
+example, you can rewrite `T2 Foo(T1 x)` to `void Foo(T1 x, T2* result)`. You
+need to make sure that `*result` contains some sensible value even when the
+function returns prematurely. As the function now returns `void`, you can use
+any assertion inside of it.
+
+If changing the function's type is not an option, you should just use assertions
+that generate non-fatal failures, such as `ADD_FAILURE*` and `EXPECT_*`.
+
+{: .callout .note}
+NOTE: Constructors and destructors are not considered void-returning functions,
+according to the C++ language specification, and so you may not use fatal
+assertions in them; you'll get a compilation error if you try. Instead, either
+call `abort` and crash the entire test executable, or put the fatal assertion in
+a `SetUp`/`TearDown` function; see
+[constructor/destructor vs. `SetUp`/`TearDown`](faq.md#CtorVsSetUp)
+
+{: .callout .warning}
+WARNING: A fatal assertion in a helper function (private void-returning method)
+called from a constructor or destructor does not terminate the current test, as
+your intuition might suggest: it merely returns from the constructor or
+destructor early, possibly leaving your object in a partially-constructed or
+partially-destructed state! You almost certainly want to `abort` or use
+`SetUp`/`TearDown` instead.
+
+## Skipping test execution
+
+Related to the assertions `SUCCEED()` and `FAIL()`, you can prevent further test
+execution at runtime with the `GTEST_SKIP()` macro. This is useful when you need
+to check for preconditions of the system under test during runtime and skip
+tests in a meaningful way.
+
+`GTEST_SKIP()` can be used in individual test cases or in the `SetUp()` methods
+of classes derived from either `::testing::Environment` or `::testing::Test`.
+For example:
+
+```c++
+TEST(SkipTest, DoesSkip) {
+ GTEST_SKIP() << "Skipping single test";
+ EXPECT_EQ(0, 1); // Won't fail; it won't be executed
+}
+
+class SkipFixture : public ::testing::Test {
+ protected:
+ void SetUp() override {
+ GTEST_SKIP() << "Skipping all tests for this fixture";
+ }
+};
+
+// Tests for SkipFixture won't be executed.
+TEST_F(SkipFixture, SkipsOneTest) {
+ EXPECT_EQ(5, 7); // Won't fail
+}
+```
+
+As with assertion macros, you can stream a custom message into `GTEST_SKIP()`.
+
+## Teaching googletest How to Print Your Values
+
+When a test assertion such as `EXPECT_EQ` fails, googletest prints the argument
+values to help you debug. It does this using a user-extensible value printer.
+
+This printer knows how to print built-in C++ types, native arrays, STL
+containers, and any type that supports the `<<` operator. For other types, it
+prints the raw bytes in the value and hopes that you the user can figure it out.
+
+As mentioned earlier, the printer is *extensible*. That means you can teach it
+to do a better job at printing your particular type than to dump the bytes. To
+do that, define `<<` for your type:
+
+```c++
+#include <ostream>
+
+namespace foo {
+
+class Bar { // We want googletest to be able to print instances of this.
+...
+ // Create a free inline friend function.
+ friend std::ostream& operator<<(std::ostream& os, const Bar& bar) {
+ return os << bar.DebugString(); // whatever needed to print bar to os
+ }
+};
+
+// If you can't declare the function in the class it's important that the
+// << operator is defined in the SAME namespace that defines Bar. C++'s look-up
+// rules rely on that.
+std::ostream& operator<<(std::ostream& os, const Bar& bar) {
+ return os << bar.DebugString(); // whatever needed to print bar to os
+}
+
+} // namespace foo
+```
+
+Sometimes, this might not be an option: your team may consider it bad style to
+have a `<<` operator for `Bar`, or `Bar` may already have a `<<` operator that
+doesn't do what you want (and you cannot change it). If so, you can instead
+define a `PrintTo()` function like this:
+
+```c++
+#include <ostream>
+
+namespace foo {
+
+class Bar {
+ ...
+ friend void PrintTo(const Bar& bar, std::ostream* os) {
+ *os << bar.DebugString(); // whatever needed to print bar to os
+ }
+};
+
+// If you can't declare the function in the class it's important that PrintTo()
+// is defined in the SAME namespace that defines Bar. C++'s look-up rules rely
+// on that.
+void PrintTo(const Bar& bar, std::ostream* os) {
+ *os << bar.DebugString(); // whatever needed to print bar to os
+}
+
+} // namespace foo
+```
+
+If you have defined both `<<` and `PrintTo()`, the latter will be used when
+googletest is concerned. This allows you to customize how the value appears in
+googletest's output without affecting code that relies on the behavior of its
+`<<` operator.
+
+If you want to print a value `x` using googletest's value printer yourself, just
+call `::testing::PrintToString(x)`, which returns an `std::string`:
+
+```c++
+vector<pair<Bar, int> > bar_ints = GetBarIntVector();
+
+EXPECT_TRUE(IsCorrectBarIntVector(bar_ints))
+ << "bar_ints = " << testing::PrintToString(bar_ints);
+```
+
+## Death Tests
+
+In many applications, there are assertions that can cause application failure if
+a condition is not met. These consistency checks, which ensure that the program
+is in a known good state, are there to fail at the earliest possible time after
+some program state is corrupted. If the assertion checks the wrong condition,
+then the program may proceed in an erroneous state, which could lead to memory
+corruption, security holes, or worse. Hence it is vitally important to test that
+such assertion statements work as expected.
+
+Since these precondition checks cause the processes to die, we call such tests
+_death tests_. More generally, any test that checks that a program terminates
+(except by throwing an exception) in an expected fashion is also a death test.
+
+Note that if a piece of code throws an exception, we don't consider it "death"
+for the purpose of death tests, as the caller of the code could catch the
+exception and avoid the crash. If you want to verify exceptions thrown by your
+code, see [Exception Assertions](#ExceptionAssertions).
+
+If you want to test `EXPECT_*()/ASSERT_*()` failures in your test code, see
+["Catching" Failures](#catching-failures).
+
+### How to Write a Death Test
+
+GoogleTest provides assertion macros to support death tests. See
+[Death Assertions](reference/assertions.md#death) in the Assertions Reference
+for details.
+
+To write a death test, simply use one of the macros inside your test function.
+For example,
+
+```c++
+TEST(MyDeathTest, Foo) {
+ // This death test uses a compound statement.
+ ASSERT_DEATH({
+ int n = 5;
+ Foo(&n);
+ }, "Error on line .* of Foo()");
+}
+
+TEST(MyDeathTest, NormalExit) {
+ EXPECT_EXIT(NormalExit(), testing::ExitedWithCode(0), "Success");
+}
+
+TEST(MyDeathTest, KillProcess) {
+ EXPECT_EXIT(KillProcess(), testing::KilledBySignal(SIGKILL),
+ "Sending myself unblockable signal");
+}
+```
+
+verifies that:
+
+* calling `Foo(5)` causes the process to die with the given error message,
+* calling `NormalExit()` causes the process to print `"Success"` to stderr and
+ exit with exit code 0, and
+* calling `KillProcess()` kills the process with signal `SIGKILL`.
+
+The test function body may contain other assertions and statements as well, if
+necessary.
+
+Note that a death test only cares about three things:
+
+1. does `statement` abort or exit the process?
+2. (in the case of `ASSERT_EXIT` and `EXPECT_EXIT`) does the exit status
+ satisfy `predicate`? Or (in the case of `ASSERT_DEATH` and `EXPECT_DEATH`)
+ is the exit status non-zero? And
+3. does the stderr output match `matcher`?
+
+In particular, if `statement` generates an `ASSERT_*` or `EXPECT_*` failure, it
+will **not** cause the death test to fail, as googletest assertions don't abort
+the process.
+
+### Death Test Naming
+
+{: .callout .important}
+IMPORTANT: We strongly recommend you to follow the convention of naming your
+**test suite** (not test) `*DeathTest` when it contains a death test, as
+demonstrated in the above example. The
+[Death Tests And Threads](#death-tests-and-threads) section below explains why.
+
+If a test fixture class is shared by normal tests and death tests, you can use
+`using` or `typedef` to introduce an alias for the fixture class and avoid
+duplicating its code:
+
+```c++
+class FooTest : public testing::Test { ... };
+
+using FooDeathTest = FooTest;
+
+TEST_F(FooTest, DoesThis) {
+ // normal test
+}
+
+TEST_F(FooDeathTest, DoesThat) {
+ // death test
+}
+```
+
+### Regular Expression Syntax
+
+On POSIX systems (e.g. Linux, Cygwin, and Mac), googletest uses the
+[POSIX extended regular expression](http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap09.html#tag_09_04)
+syntax. To learn about this syntax, you may want to read this
+[Wikipedia entry](http://en.wikipedia.org/wiki/Regular_expression#POSIX_Extended_Regular_Expressions).
+
+On Windows, googletest uses its own simple regular expression implementation. It
+lacks many features. For example, we don't support union (`"x|y"`), grouping
+(`"(xy)"`), brackets (`"[xy]"`), and repetition count (`"x{5,7}"`), among
+others. Below is what we do support (`A` denotes a literal character, period
+(`.`), or a single `\\ ` escape sequence; `x` and `y` denote regular
+expressions.):
+
+Expression | Meaning
+---------- | --------------------------------------------------------------
+`c` | matches any literal character `c`
+`\\d` | matches any decimal digit
+`\\D` | matches any character that's not a decimal digit
+`\\f` | matches `\f`
+`\\n` | matches `\n`
+`\\r` | matches `\r`
+`\\s` | matches any ASCII whitespace, including `\n`
+`\\S` | matches any character that's not a whitespace
+`\\t` | matches `\t`
+`\\v` | matches `\v`
+`\\w` | matches any letter, `_`, or decimal digit
+`\\W` | matches any character that `\\w` doesn't match
+`\\c` | matches any literal character `c`, which must be a punctuation
+`.` | matches any single character except `\n`
+`A?` | matches 0 or 1 occurrences of `A`
+`A*` | matches 0 or many occurrences of `A`
+`A+` | matches 1 or many occurrences of `A`
+`^` | matches the beginning of a string (not that of each line)
+`$` | matches the end of a string (not that of each line)
+`xy` | matches `x` followed by `y`
+
+To help you determine which capability is available on your system, googletest
+defines macros to govern which regular expression it is using. The macros are:
+`GTEST_USES_SIMPLE_RE=1` or `GTEST_USES_POSIX_RE=1`. If you want your death
+tests to work in all cases, you can either `#if` on these macros or use the more
+limited syntax only.
+
+### How It Works
+
+See [Death Assertions](reference/assertions.md#death) in the Assertions
+Reference.
+
+### Death Tests And Threads
+
+The reason for the two death test styles has to do with thread safety. Due to
+well-known problems with forking in the presence of threads, death tests should
+be run in a single-threaded context. Sometimes, however, it isn't feasible to
+arrange that kind of environment. For example, statically-initialized modules
+may start threads before main is ever reached. Once threads have been created,
+it may be difficult or impossible to clean them up.
+
+googletest has three features intended to raise awareness of threading issues.
+
+1. A warning is emitted if multiple threads are running when a death test is
+ encountered.
+2. Test suites with a name ending in "DeathTest" are run before all other
+ tests.
+3. It uses `clone()` instead of `fork()` to spawn the child process on Linux
+ (`clone()` is not available on Cygwin and Mac), as `fork()` is more likely
+ to cause the child to hang when the parent process has multiple threads.
+
+It's perfectly fine to create threads inside a death test statement; they are
+executed in a separate process and cannot affect the parent.
+
+### Death Test Styles
+
+The "threadsafe" death test style was introduced in order to help mitigate the
+risks of testing in a possibly multithreaded environment. It trades increased
+test execution time (potentially dramatically so) for improved thread safety.
+
+The automated testing framework does not set the style flag. You can choose a
+particular style of death tests by setting the flag programmatically:
+
+```c++
+GTEST_FLAG_SET(death_test_style, "threadsafe")
+```
+
+You can do this in `main()` to set the style for all death tests in the binary,
+or in individual tests. Recall that flags are saved before running each test and
+restored afterwards, so you need not do that yourself. For example:
+
+```c++
+int main(int argc, char** argv) {
+ testing::InitGoogleTest(&argc, argv);
+ GTEST_FLAG_SET(death_test_style, "fast");
+ return RUN_ALL_TESTS();
+}
+
+TEST(MyDeathTest, TestOne) {
+ GTEST_FLAG_SET(death_test_style, "threadsafe");
+ // This test is run in the "threadsafe" style:
+ ASSERT_DEATH(ThisShouldDie(), "");
+}
+
+TEST(MyDeathTest, TestTwo) {
+ // This test is run in the "fast" style:
+ ASSERT_DEATH(ThisShouldDie(), "");
+}
+```
+
+### Caveats
+
+The `statement` argument of `ASSERT_EXIT()` can be any valid C++ statement. If
+it leaves the current function via a `return` statement or by throwing an
+exception, the death test is considered to have failed. Some googletest macros
+may return from the current function (e.g. `ASSERT_TRUE()`), so be sure to avoid
+them in `statement`.
+
+Since `statement` runs in the child process, any in-memory side effect (e.g.
+modifying a variable, releasing memory, etc) it causes will *not* be observable
+in the parent process. In particular, if you release memory in a death test,
+your program will fail the heap check as the parent process will never see the
+memory reclaimed. To solve this problem, you can
+
+1. try not to free memory in a death test;
+2. free the memory again in the parent process; or
+3. do not use the heap checker in your program.
+
+Due to an implementation detail, you cannot place multiple death test assertions
+on the same line; otherwise, compilation will fail with an unobvious error
+message.
+
+Despite the improved thread safety afforded by the "threadsafe" style of death
+test, thread problems such as deadlock are still possible in the presence of
+handlers registered with `pthread_atfork(3)`.
+
+## Using Assertions in Sub-routines
+
+{: .callout .note}
+Note: If you want to put a series of test assertions in a subroutine to check
+for a complex condition, consider using
+[a custom GMock matcher](gmock_cook_book.md#NewMatchers) instead. This lets you
+provide a more readable error message in case of failure and avoid all of the
+issues described below.
+
+### Adding Traces to Assertions
+
+If a test sub-routine is called from several places, when an assertion inside it
+fails, it can be hard to tell which invocation of the sub-routine the failure is
+from. You can alleviate this problem using extra logging or custom failure
+messages, but that usually clutters up your tests. A better solution is to use
+the `SCOPED_TRACE` macro or the `ScopedTrace` utility:
+
+```c++
+SCOPED_TRACE(message);
+```
+
+```c++
+ScopedTrace trace("file_path", line_number, message);
+```
+
+where `message` can be anything streamable to `std::ostream`. `SCOPED_TRACE`
+macro will cause the current file name, line number, and the given message to be
+added in every failure message. `ScopedTrace` accepts explicit file name and
+line number in arguments, which is useful for writing test helpers. The effect
+will be undone when the control leaves the current lexical scope.
+
+For example,
+
+```c++
+10: void Sub1(int n) {
+11: EXPECT_EQ(Bar(n), 1);
+12: EXPECT_EQ(Bar(n + 1), 2);
+13: }
+14:
+15: TEST(FooTest, Bar) {
+16: {
+17: SCOPED_TRACE("A"); // This trace point will be included in
+18: // every failure in this scope.
+19: Sub1(1);
+20: }
+21: // Now it won't.
+22: Sub1(9);
+23: }
+```
+
+could result in messages like these:
+
+```none
+path/to/foo_test.cc:11: Failure
+Value of: Bar(n)
+Expected: 1
+ Actual: 2
+Google Test trace:
+path/to/foo_test.cc:17: A
+
+path/to/foo_test.cc:12: Failure
+Value of: Bar(n + 1)
+Expected: 2
+ Actual: 3
+```
+
+Without the trace, it would've been difficult to know which invocation of
+`Sub1()` the two failures come from respectively. (You could add an extra
+message to each assertion in `Sub1()` to indicate the value of `n`, but that's
+tedious.)
+
+Some tips on using `SCOPED_TRACE`:
+
+1. With a suitable message, it's often enough to use `SCOPED_TRACE` at the
+ beginning of a sub-routine, instead of at each call site.
+2. When calling sub-routines inside a loop, make the loop iterator part of the
+ message in `SCOPED_TRACE` such that you can know which iteration the failure
+ is from.
+3. Sometimes the line number of the trace point is enough for identifying the
+ particular invocation of a sub-routine. In this case, you don't have to
+ choose a unique message for `SCOPED_TRACE`. You can simply use `""`.
+4. You can use `SCOPED_TRACE` in an inner scope when there is one in the outer
+ scope. In this case, all active trace points will be included in the failure
+ messages, in reverse order they are encountered.
+5. The trace dump is clickable in Emacs - hit `return` on a line number and
+ you'll be taken to that line in the source file!
+
+### Propagating Fatal Failures
+
+A common pitfall when using `ASSERT_*` and `FAIL*` is not understanding that
+when they fail they only abort the _current function_, not the entire test. For
+example, the following test will segfault:
+
+```c++
+void Subroutine() {
+ // Generates a fatal failure and aborts the current function.
+ ASSERT_EQ(1, 2);
+
+ // The following won't be executed.
+ ...
+}
+
+TEST(FooTest, Bar) {
+ Subroutine(); // The intended behavior is for the fatal failure
+ // in Subroutine() to abort the entire test.
+
+ // The actual behavior: the function goes on after Subroutine() returns.
+ int* p = nullptr;
+ *p = 3; // Segfault!
+}
+```
+
+To alleviate this, googletest provides three different solutions. You could use
+either exceptions, the `(ASSERT|EXPECT)_NO_FATAL_FAILURE` assertions or the
+`HasFatalFailure()` function. They are described in the following two
+subsections.
+
+#### Asserting on Subroutines with an exception
+
+The following code can turn ASSERT-failure into an exception:
+
+```c++
+class ThrowListener : public testing::EmptyTestEventListener {
+ void OnTestPartResult(const testing::TestPartResult& result) override {
+ if (result.type() == testing::TestPartResult::kFatalFailure) {
+ throw testing::AssertionException(result);
+ }
+ }
+};
+int main(int argc, char** argv) {
+ ...
+ testing::UnitTest::GetInstance()->listeners().Append(new ThrowListener);
+ return RUN_ALL_TESTS();
+}
+```
+
+This listener should be added after other listeners if you have any, otherwise
+they won't see failed `OnTestPartResult`.
+
+#### Asserting on Subroutines
+
+As shown above, if your test calls a subroutine that has an `ASSERT_*` failure
+in it, the test will continue after the subroutine returns. This may not be what
+you want.
+
+Often people want fatal failures to propagate like exceptions. For that
+googletest offers the following macros:
+
+Fatal assertion | Nonfatal assertion | Verifies
+------------------------------------- | ------------------------------------- | --------
+`ASSERT_NO_FATAL_FAILURE(statement);` | `EXPECT_NO_FATAL_FAILURE(statement);` | `statement` doesn't generate any new fatal failures in the current thread.
+
+Only failures in the thread that executes the assertion are checked to determine
+the result of this type of assertions. If `statement` creates new threads,
+failures in these threads are ignored.
+
+Examples:
+
+```c++
+ASSERT_NO_FATAL_FAILURE(Foo());
+
+int i;
+EXPECT_NO_FATAL_FAILURE({
+ i = Bar();
+});
+```
+
+Assertions from multiple threads are currently not supported on Windows.
+
+#### Checking for Failures in the Current Test
+
+`HasFatalFailure()` in the `::testing::Test` class returns `true` if an
+assertion in the current test has suffered a fatal failure. This allows
+functions to catch fatal failures in a sub-routine and return early.
+
+```c++
+class Test {
+ public:
+ ...
+ static bool HasFatalFailure();
+};
+```
+
+The typical usage, which basically simulates the behavior of a thrown exception,
+is:
+
+```c++
+TEST(FooTest, Bar) {
+ Subroutine();
+ // Aborts if Subroutine() had a fatal failure.
+ if (HasFatalFailure()) return;
+
+ // The following won't be executed.
+ ...
+}
+```
+
+If `HasFatalFailure()` is used outside of `TEST()` , `TEST_F()` , or a test
+fixture, you must add the `::testing::Test::` prefix, as in:
+
+```c++
+if (testing::Test::HasFatalFailure()) return;
+```
+
+Similarly, `HasNonfatalFailure()` returns `true` if the current test has at
+least one non-fatal failure, and `HasFailure()` returns `true` if the current
+test has at least one failure of either kind.
+
+## Logging Additional Information
+
+In your test code, you can call `RecordProperty("key", value)` to log additional
+information, where `value` can be either a string or an `int`. The *last* value
+recorded for a key will be emitted to the
+[XML output](#generating-an-xml-report) if you specify one. For example, the
+test
+
+```c++
+TEST_F(WidgetUsageTest, MinAndMaxWidgets) {
+ RecordProperty("MaximumWidgets", ComputeMaxUsage());
+ RecordProperty("MinimumWidgets", ComputeMinUsage());
+}
+```
+
+will output XML like this:
+
+```xml
+ ...
+ <testcase name="MinAndMaxWidgets" status="run" time="0.006" classname="WidgetUsageTest" MaximumWidgets="12" MinimumWidgets="9" />
+ ...
+```
+
+{: .callout .note}
+> NOTE:
+>
+> * `RecordProperty()` is a static member of the `Test` class. Therefore it
+> needs to be prefixed with `::testing::Test::` if used outside of the
+> `TEST` body and the test fixture class.
+> * *`key`* must be a valid XML attribute name, and cannot conflict with the
+> ones already used by googletest (`name`, `status`, `time`, `classname`,
+> `type_param`, and `value_param`).
+> * Calling `RecordProperty()` outside of the lifespan of a test is allowed.
+> If it's called outside of a test but between a test suite's
+> `SetUpTestSuite()` and `TearDownTestSuite()` methods, it will be
+> attributed to the XML element for the test suite. If it's called outside
+> of all test suites (e.g. in a test environment), it will be attributed to
+> the top-level XML element.
+
+## Sharing Resources Between Tests in the Same Test Suite
+
+googletest creates a new test fixture object for each test in order to make
+tests independent and easier to debug. However, sometimes tests use resources
+that are expensive to set up, making the one-copy-per-test model prohibitively
+expensive.
+
+If the tests don't change the resource, there's no harm in their sharing a
+single resource copy. So, in addition to per-test set-up/tear-down, googletest
+also supports per-test-suite set-up/tear-down. To use it:
+
+1. In your test fixture class (say `FooTest` ), declare as `static` some member
+ variables to hold the shared resources.
+2. Outside your test fixture class (typically just below it), define those
+ member variables, optionally giving them initial values.
+3. In the same test fixture class, define a `static void SetUpTestSuite()`
+ function (remember not to spell it as **`SetupTestSuite`** with a small
+ `u`!) to set up the shared resources and a `static void TearDownTestSuite()`
+ function to tear them down.
+
+That's it! googletest automatically calls `SetUpTestSuite()` before running the
+*first test* in the `FooTest` test suite (i.e. before creating the first
+`FooTest` object), and calls `TearDownTestSuite()` after running the *last test*
+in it (i.e. after deleting the last `FooTest` object). In between, the tests can
+use the shared resources.
+
+Remember that the test order is undefined, so your code can't depend on a test
+preceding or following another. Also, the tests must either not modify the state
+of any shared resource, or, if they do modify the state, they must restore the
+state to its original value before passing control to the next test.
+
+Note that `SetUpTestSuite()` may be called multiple times for a test fixture
+class that has derived classes, so you should not expect code in the function
+body to be run only once. Also, derived classes still have access to shared
+resources defined as static members, so careful consideration is needed when
+managing shared resources to avoid memory leaks.
+
+Here's an example of per-test-suite set-up and tear-down:
+
+```c++
+class FooTest : public testing::Test {
+ protected:
+ // Per-test-suite set-up.
+ // Called before the first test in this test suite.
+ // Can be omitted if not needed.
+ static void SetUpTestSuite() {
+ // Avoid reallocating static objects if called in subclasses of FooTest.
+ if (shared_resource_ == nullptr) {
+ shared_resource_ = new ...;
+ }
+ }
+
+ // Per-test-suite tear-down.
+ // Called after the last test in this test suite.
+ // Can be omitted if not needed.
+ static void TearDownTestSuite() {
+ delete shared_resource_;
+ shared_resource_ = nullptr;
+ }
+
+ // You can define per-test set-up logic as usual.
+ void SetUp() override { ... }
+
+ // You can define per-test tear-down logic as usual.
+ void TearDown() override { ... }
+
+ // Some expensive resource shared by all tests.
+ static T* shared_resource_;
+};
+
+T* FooTest::shared_resource_ = nullptr;
+
+TEST_F(FooTest, Test1) {
+ ... you can refer to shared_resource_ here ...
+}
+
+TEST_F(FooTest, Test2) {
+ ... you can refer to shared_resource_ here ...
+}
+```
+
+{: .callout .note}
+NOTE: Though the above code declares `SetUpTestSuite()` protected, it may
+sometimes be necessary to declare it public, such as when using it with
+`TEST_P`.
+
+## Global Set-Up and Tear-Down
+
+Just as you can do set-up and tear-down at the test level and the test suite
+level, you can also do it at the test program level. Here's how.
+
+First, you subclass the `::testing::Environment` class to define a test
+environment, which knows how to set-up and tear-down:
+
+```c++
+class Environment : public ::testing::Environment {
+ public:
+ ~Environment() override {}
+
+ // Override this to define how to set up the environment.
+ void SetUp() override {}
+
+ // Override this to define how to tear down the environment.
+ void TearDown() override {}
+};
+```
+
+Then, you register an instance of your environment class with googletest by
+calling the `::testing::AddGlobalTestEnvironment()` function:
+
+```c++
+Environment* AddGlobalTestEnvironment(Environment* env);
+```
+
+Now, when `RUN_ALL_TESTS()` is called, it first calls the `SetUp()` method of
+each environment object, then runs the tests if none of the environments
+reported fatal failures and `GTEST_SKIP()` was not called. `RUN_ALL_TESTS()`
+always calls `TearDown()` with each environment object, regardless of whether or
+not the tests were run.
+
+It's OK to register multiple environment objects. In this suite, their `SetUp()`
+will be called in the order they are registered, and their `TearDown()` will be
+called in the reverse order.
+
+Note that googletest takes ownership of the registered environment objects.
+Therefore **do not delete them** by yourself.
+
+You should call `AddGlobalTestEnvironment()` before `RUN_ALL_TESTS()` is called,
+probably in `main()`. If you use `gtest_main`, you need to call this before
+`main()` starts for it to take effect. One way to do this is to define a global
+variable like this:
+
+```c++
+testing::Environment* const foo_env =
+ testing::AddGlobalTestEnvironment(new FooEnvironment);
+```
+
+However, we strongly recommend you to write your own `main()` and call
+`AddGlobalTestEnvironment()` there, as relying on initialization of global
+variables makes the code harder to read and may cause problems when you register
+multiple environments from different translation units and the environments have
+dependencies among them (remember that the compiler doesn't guarantee the order
+in which global variables from different translation units are initialized).
+
+## Value-Parameterized Tests
+
+*Value-parameterized tests* allow you to test your code with different
+parameters without writing multiple copies of the same test. This is useful in a
+number of situations, for example:
+
+* You have a piece of code whose behavior is affected by one or more
+ command-line flags. You want to make sure your code performs correctly for
+ various values of those flags.
+* You want to test different implementations of an OO interface.
+* You want to test your code over various inputs (a.k.a. data-driven testing).
+ This feature is easy to abuse, so please exercise your good sense when doing
+ it!
+
+### How to Write Value-Parameterized Tests
+
+To write value-parameterized tests, first you should define a fixture class. It
+must be derived from both `testing::Test` and `testing::WithParamInterface<T>`
+(the latter is a pure interface), where `T` is the type of your parameter
+values. For convenience, you can just derive the fixture class from
+`testing::TestWithParam<T>`, which itself is derived from both `testing::Test`
+and `testing::WithParamInterface<T>`. `T` can be any copyable type. If it's a
+raw pointer, you are responsible for managing the lifespan of the pointed
+values.
+
+{: .callout .note}
+NOTE: If your test fixture defines `SetUpTestSuite()` or `TearDownTestSuite()`
+they must be declared **public** rather than **protected** in order to use
+`TEST_P`.
+
+```c++
+class FooTest :
+ public testing::TestWithParam<const char*> {
+ // You can implement all the usual fixture class members here.
+ // To access the test parameter, call GetParam() from class
+ // TestWithParam<T>.
+};
+
+// Or, when you want to add parameters to a pre-existing fixture class:
+class BaseTest : public testing::Test {
+ ...
+};
+class BarTest : public BaseTest,
+ public testing::WithParamInterface<const char*> {
+ ...
+};
+```
+
+Then, use the `TEST_P` macro to define as many test patterns using this fixture
+as you want. The `_P` suffix is for "parameterized" or "pattern", whichever you
+prefer to think.
+
+```c++
+TEST_P(FooTest, DoesBlah) {
+ // Inside a test, access the test parameter with the GetParam() method
+ // of the TestWithParam<T> class:
+ EXPECT_TRUE(foo.Blah(GetParam()));
+ ...
+}
+
+TEST_P(FooTest, HasBlahBlah) {
+ ...
+}
+```
+
+Finally, you can use the `INSTANTIATE_TEST_SUITE_P` macro to instantiate the
+test suite with any set of parameters you want. GoogleTest defines a number of
+functions for generating test parameters—see details at
+[`INSTANTIATE_TEST_SUITE_P`](reference/testing.md#INSTANTIATE_TEST_SUITE_P) in
+the Testing Reference.
+
+For example, the following statement will instantiate tests from the `FooTest`
+test suite each with parameter values `"meeny"`, `"miny"`, and `"moe"` using the
+[`Values`](reference/testing.md#param-generators) parameter generator:
+
+```c++
+INSTANTIATE_TEST_SUITE_P(MeenyMinyMoe,
+ FooTest,
+ testing::Values("meeny", "miny", "moe"));
+```
+
+{: .callout .note}
+NOTE: The code above must be placed at global or namespace scope, not at
+function scope.
+
+The first argument to `INSTANTIATE_TEST_SUITE_P` is a unique name for the
+instantiation of the test suite. The next argument is the name of the test
+pattern, and the last is the
+[parameter generator](reference/testing.md#param-generators).
+
+You can instantiate a test pattern more than once, so to distinguish different
+instances of the pattern, the instantiation name is added as a prefix to the
+actual test suite name. Remember to pick unique prefixes for different
+instantiations. The tests from the instantiation above will have these names:
+
+* `MeenyMinyMoe/FooTest.DoesBlah/0` for `"meeny"`
+* `MeenyMinyMoe/FooTest.DoesBlah/1` for `"miny"`
+* `MeenyMinyMoe/FooTest.DoesBlah/2` for `"moe"`
+* `MeenyMinyMoe/FooTest.HasBlahBlah/0` for `"meeny"`
+* `MeenyMinyMoe/FooTest.HasBlahBlah/1` for `"miny"`
+* `MeenyMinyMoe/FooTest.HasBlahBlah/2` for `"moe"`
+
+You can use these names in [`--gtest_filter`](#running-a-subset-of-the-tests).
+
+The following statement will instantiate all tests from `FooTest` again, each
+with parameter values `"cat"` and `"dog"` using the
+[`ValuesIn`](reference/testing.md#param-generators) parameter generator:
+
+```c++
+const char* pets[] = {"cat", "dog"};
+INSTANTIATE_TEST_SUITE_P(Pets, FooTest, testing::ValuesIn(pets));
+```
+
+The tests from the instantiation above will have these names:
+
+* `Pets/FooTest.DoesBlah/0` for `"cat"`
+* `Pets/FooTest.DoesBlah/1` for `"dog"`
+* `Pets/FooTest.HasBlahBlah/0` for `"cat"`
+* `Pets/FooTest.HasBlahBlah/1` for `"dog"`
+
+Please note that `INSTANTIATE_TEST_SUITE_P` will instantiate *all* tests in the
+given test suite, whether their definitions come before or *after* the
+`INSTANTIATE_TEST_SUITE_P` statement.
+
+Additionally, by default, every `TEST_P` without a corresponding
+`INSTANTIATE_TEST_SUITE_P` causes a failing test in test suite
+`GoogleTestVerification`. If you have a test suite where that omission is not an
+error, for example it is in a library that may be linked in for other reasons or
+where the list of test cases is dynamic and may be empty, then this check can be
+suppressed by tagging the test suite:
+
+```c++
+GTEST_ALLOW_UNINSTANTIATED_PARAMETERIZED_TEST(FooTest);
+```
+
+You can see [sample7_unittest.cc] and [sample8_unittest.cc] for more examples.
+
+[sample7_unittest.cc]: https://github.com/google/googletest/blob/master/googletest/samples/sample7_unittest.cc "Parameterized Test example"
+[sample8_unittest.cc]: https://github.com/google/googletest/blob/master/googletest/samples/sample8_unittest.cc "Parameterized Test example with multiple parameters"
+
+### Creating Value-Parameterized Abstract Tests
+
+In the above, we define and instantiate `FooTest` in the *same* source file.
+Sometimes you may want to define value-parameterized tests in a library and let
+other people instantiate them later. This pattern is known as *abstract tests*.
+As an example of its application, when you are designing an interface you can
+write a standard suite of abstract tests (perhaps using a factory function as
+the test parameter) that all implementations of the interface are expected to
+pass. When someone implements the interface, they can instantiate your suite to
+get all the interface-conformance tests for free.
+
+To define abstract tests, you should organize your code like this:
+
+1. Put the definition of the parameterized test fixture class (e.g. `FooTest`)
+ in a header file, say `foo_param_test.h`. Think of this as *declaring* your
+ abstract tests.
+2. Put the `TEST_P` definitions in `foo_param_test.cc`, which includes
+ `foo_param_test.h`. Think of this as *implementing* your abstract tests.
+
+Once they are defined, you can instantiate them by including `foo_param_test.h`,
+invoking `INSTANTIATE_TEST_SUITE_P()`, and depending on the library target that
+contains `foo_param_test.cc`. You can instantiate the same abstract test suite
+multiple times, possibly in different source files.
+
+### Specifying Names for Value-Parameterized Test Parameters
+
+The optional last argument to `INSTANTIATE_TEST_SUITE_P()` allows the user to
+specify a function or functor that generates custom test name suffixes based on
+the test parameters. The function should accept one argument of type
+`testing::TestParamInfo<class ParamType>`, and return `std::string`.
+
+`testing::PrintToStringParamName` is a builtin test suffix generator that
+returns the value of `testing::PrintToString(GetParam())`. It does not work for
+`std::string` or C strings.
+
+{: .callout .note}
+NOTE: test names must be non-empty, unique, and may only contain ASCII
+alphanumeric characters. In particular, they
+[should not contain underscores](faq.md#why-should-test-suite-names-and-test-names-not-contain-underscore)
+
+```c++
+class MyTestSuite : public testing::TestWithParam<int> {};
+
+TEST_P(MyTestSuite, MyTest)
+{
+ std::cout << "Example Test Param: " << GetParam() << std::endl;
+}
+
+INSTANTIATE_TEST_SUITE_P(MyGroup, MyTestSuite, testing::Range(0, 10),
+ testing::PrintToStringParamName());
+```
+
+Providing a custom functor allows for more control over test parameter name
+generation, especially for types where the automatic conversion does not
+generate helpful parameter names (e.g. strings as demonstrated above). The
+following example illustrates this for multiple parameters, an enumeration type
+and a string, and also demonstrates how to combine generators. It uses a lambda
+for conciseness:
+
+```c++
+enum class MyType { MY_FOO = 0, MY_BAR = 1 };
+
+class MyTestSuite : public testing::TestWithParam<std::tuple<MyType, std::string>> {
+};
+
+INSTANTIATE_TEST_SUITE_P(
+ MyGroup, MyTestSuite,
+ testing::Combine(
+ testing::Values(MyType::MY_FOO, MyType::MY_BAR),
+ testing::Values("A", "B")),
+ [](const testing::TestParamInfo<MyTestSuite::ParamType>& info) {
+ std::string name = absl::StrCat(
+ std::get<0>(info.param) == MyType::MY_FOO ? "Foo" : "Bar",
+ std::get<1>(info.param));
+ absl::c_replace_if(name, [](char c) { return !std::isalnum(c); }, '_');
+ return name;
+ });
+```
+
+## Typed Tests
+
+Suppose you have multiple implementations of the same interface and want to make
+sure that all of them satisfy some common requirements. Or, you may have defined
+several types that are supposed to conform to the same "concept" and you want to
+verify it. In both cases, you want the same test logic repeated for different
+types.
+
+While you can write one `TEST` or `TEST_F` for each type you want to test (and
+you may even factor the test logic into a function template that you invoke from
+the `TEST`), it's tedious and doesn't scale: if you want `m` tests over `n`
+types, you'll end up writing `m*n` `TEST`s.
+
+*Typed tests* allow you to repeat the same test logic over a list of types. You
+only need to write the test logic once, although you must know the type list
+when writing typed tests. Here's how you do it:
+
+First, define a fixture class template. It should be parameterized by a type.
+Remember to derive it from `::testing::Test`:
+
+```c++
+template <typename T>
+class FooTest : public testing::Test {
+ public:
+ ...
+ using List = std::list<T>;
+ static T shared_;
+ T value_;
+};
+```
+
+Next, associate a list of types with the test suite, which will be repeated for
+each type in the list:
+
+```c++
+using MyTypes = ::testing::Types<char, int, unsigned int>;
+TYPED_TEST_SUITE(FooTest, MyTypes);
+```
+
+The type alias (`using` or `typedef`) is necessary for the `TYPED_TEST_SUITE`
+macro to parse correctly. Otherwise the compiler will think that each comma in
+the type list introduces a new macro argument.
+
+Then, use `TYPED_TEST()` instead of `TEST_F()` to define a typed test for this
+test suite. You can repeat this as many times as you want:
+
+```c++
+TYPED_TEST(FooTest, DoesBlah) {
+ // Inside a test, refer to the special name TypeParam to get the type
+ // parameter. Since we are inside a derived class template, C++ requires
+ // us to visit the members of FooTest via 'this'.
+ TypeParam n = this->value_;
+
+ // To visit static members of the fixture, add the 'TestFixture::'
+ // prefix.
+ n += TestFixture::shared_;
+
+ // To refer to typedefs in the fixture, add the 'typename TestFixture::'
+ // prefix. The 'typename' is required to satisfy the compiler.
+ typename TestFixture::List values;
+
+ values.push_back(n);
+ ...
+}
+
+TYPED_TEST(FooTest, HasPropertyA) { ... }
+```
+
+You can see [sample6_unittest.cc] for a complete example.
+
+[sample6_unittest.cc]: https://github.com/google/googletest/blob/master/googletest/samples/sample6_unittest.cc "Typed Test example"
+
+## Type-Parameterized Tests
+
+*Type-parameterized tests* are like typed tests, except that they don't require
+you to know the list of types ahead of time. Instead, you can define the test
+logic first and instantiate it with different type lists later. You can even
+instantiate it more than once in the same program.
+
+If you are designing an interface or concept, you can define a suite of
+type-parameterized tests to verify properties that any valid implementation of
+the interface/concept should have. Then, the author of each implementation can
+just instantiate the test suite with their type to verify that it conforms to
+the requirements, without having to write similar tests repeatedly. Here's an
+example:
+
+First, define a fixture class template, as we did with typed tests:
+
+```c++
+template <typename T>
+class FooTest : public testing::Test {
+ ...
+};
+```
+
+Next, declare that you will define a type-parameterized test suite:
+
+```c++
+TYPED_TEST_SUITE_P(FooTest);
+```
+
+Then, use `TYPED_TEST_P()` to define a type-parameterized test. You can repeat
+this as many times as you want:
+
+```c++
+TYPED_TEST_P(FooTest, DoesBlah) {
+ // Inside a test, refer to TypeParam to get the type parameter.
+ TypeParam n = 0;
+ ...
+}
+
+TYPED_TEST_P(FooTest, HasPropertyA) { ... }
+```
+
+Now the tricky part: you need to register all test patterns using the
+`REGISTER_TYPED_TEST_SUITE_P` macro before you can instantiate them. The first
+argument of the macro is the test suite name; the rest are the names of the
+tests in this test suite:
+
+```c++
+REGISTER_TYPED_TEST_SUITE_P(FooTest,
+ DoesBlah, HasPropertyA);
+```
+
+Finally, you are free to instantiate the pattern with the types you want. If you
+put the above code in a header file, you can `#include` it in multiple C++
+source files and instantiate it multiple times.
+
+```c++
+using MyTypes = ::testing::Types<char, int, unsigned int>;
+INSTANTIATE_TYPED_TEST_SUITE_P(My, FooTest, MyTypes);
+```
+
+To distinguish different instances of the pattern, the first argument to the
+`INSTANTIATE_TYPED_TEST_SUITE_P` macro is a prefix that will be added to the
+actual test suite name. Remember to pick unique prefixes for different
+instances.
+
+In the special case where the type list contains only one type, you can write
+that type directly without `::testing::Types<...>`, like this:
+
+```c++
+INSTANTIATE_TYPED_TEST_SUITE_P(My, FooTest, int);
+```
+
+You can see [sample6_unittest.cc] for a complete example.

+If you change your software's internal implementation, your tests should not
+break as long as the change is not observable by users. Therefore, **per the
+black-box testing principle, most of the time you should test your code through
+its public interfaces.**
+
+**If you still find yourself needing to test internal implementation code,
+consider if there's a better design.** The desire to test internal
+implementation is often a sign that the class is doing too much. Consider
+extracting an implementation class, and testing it. Then use that implementation
+class in the original class.
+
+If you absolutely have to test non-public interface code though, you can. There
+are two cases to consider:
+
+* Static functions ( *not* the same as static member functions!) or unnamed
+ namespaces, and
+* Private or protected class members
+
+To test them, we use the following special techniques:
+
+* Both static functions and definitions/declarations in an unnamed namespace
+ are only visible within the same translation unit. To test them, you can
+ `#include` the entire `.cc` file being tested in your `*_test.cc` file.
+ (#including `.cc` files is not a good way to reuse code - you should not do
+ this in production code!)
+
+ However, a better approach is to move the private code into the
+ `foo::internal` namespace, where `foo` is the namespace your project
+ normally uses, and put the private declarations in a `*-internal.h` file.
+ Your production `.cc` files and your tests are allowed to include this
+ internal header, but your clients are not. This way, you can fully test your
+ internal implementation without leaking it to your clients.
+
+* Private class members are only accessible from within the class or by
+ friends. To access a class' private members, you can declare your test
+ fixture as a friend to the class and define accessors in your fixture. Tests
+ using the fixture can then access the private members of your production
+ class via the accessors in the fixture. Note that even though your fixture
+ is a friend to your production class, your tests are not automatically
+ friends to it, as they are technically defined in sub-classes of the
+ fixture.
+
+ Another way to test private members is to refactor them into an
+ implementation class, which is then declared in a `*-internal.h` file. Your
+ clients aren't allowed to include this header but your tests can. Such is
+ called the
+ [Pimpl](https://www.gamedev.net/articles/programming/general-and-gameplay-programming/the-c-pimpl-r1794/)
+ (Private Implementation) idiom.
+
+ Or, you can declare an individual test as a friend of your class by adding
+ this line in the class body:
+
+ ```c++
+ FRIEND_TEST(TestSuiteName, TestName);
+ ```
+
+ For example,
+
+ ```c++
+ // foo.h
+ class Foo {
+ ...
+ private:
+ FRIEND_TEST(FooTest, BarReturnsZeroOnNull);
+
+ int Bar(void* x);
+ };
+
+ // foo_test.cc
+ ...
+ TEST(FooTest, BarReturnsZeroOnNull) {
+ Foo foo;
+ EXPECT_EQ(foo.Bar(NULL), 0); // Uses Foo's private member Bar().
+ }
+ ```
+
+ Pay special attention when your class is defined in a namespace. If you want
+ your test fixtures and tests to be friends of your class, then they must be
+ defined in the exact same namespace (no anonymous or inline namespaces).
+
+ For example, if the code to be tested looks like:
+
+ ```c++
+ namespace my_namespace {
+
+ class Foo {
+ friend class FooTest;
+ FRIEND_TEST(FooTest, Bar);
+ FRIEND_TEST(FooTest, Baz);
+ ... definition of the class Foo ...
+ };
+
+ } // namespace my_namespace
+ ```
+
+ Your test code should be something like:
+
+ ```c++
+ namespace my_namespace {
+
+ class FooTest : public testing::Test {
+ protected:
+ ...
+ };
+
+ TEST_F(FooTest, Bar) { ... }
+ TEST_F(FooTest, Baz) { ... }
+
+ } // namespace my_namespace
+ ```
+
+## "Catching" Failures
+
+If you are building a testing utility on top of googletest, you'll want to test
+your utility. What framework would you use to test it? googletest, of course.
+
+The challenge is to verify that your testing utility reports failures correctly.
+In frameworks that report a failure by throwing an exception, you could catch
+the exception and assert on it. But googletest doesn't use exceptions, so how do
+we test that a piece of code generates an expected failure?
+
+`"gtest/gtest-spi.h"` contains some constructs to do this.
+After #including this header, you can use
+
+```c++
+ EXPECT_FATAL_FAILURE(statement, substring);
+```
+
+to assert that `statement` generates a fatal (e.g. `ASSERT_*`) failure in the
+current thread whose message contains the given `substring`, or use
+
+```c++
+ EXPECT_NONFATAL_FAILURE(statement, substring);
+```
+
+if you are expecting a non-fatal (e.g. `EXPECT_*`) failure.
+
+Only failures in the current thread are checked to determine the result of this
+type of expectations. If `statement` creates new threads, failures in these
+threads are also ignored. If you want to catch failures in other threads as
+well, use one of the following macros instead:
+
+```c++
+ EXPECT_FATAL_FAILURE_ON_ALL_THREADS(statement, substring);
+ EXPECT_NONFATAL_FAILURE_ON_ALL_THREADS(statement, substring);
+```
+
+{: .callout .note}
+NOTE: Assertions from multiple threads are currently not supported on Windows.
+
+For technical reasons, there are some caveats:
+
+1. You cannot stream a failure message to either macro.
+
+2. `statement` in `EXPECT_FATAL_FAILURE{_ON_ALL_THREADS}()` cannot reference
+ local non-static variables or non-static members of `this` object.
+
+3. `statement` in `EXPECT_FATAL_FAILURE{_ON_ALL_THREADS}()` cannot return a
+ value.
+
+## Registering tests programmatically
+
+The `TEST` macros handle the vast majority of all use cases, but there are few
+where runtime registration logic is required. For those cases, the framework
+provides the `::testing::RegisterTest` that allows callers to register arbitrary
+tests dynamically.
+
+This is an advanced API only to be used when the `TEST` macros are insufficient.
+The macros should be preferred when possible, as they avoid most of the
+complexity of calling this function.
+
+It provides the following signature:
+
+```c++
+template <typename Factory>
+TestInfo* RegisterTest(const char* test_suite_name, const char* test_name,
+ const char* type_param, const char* value_param,
+ const char* file, int line, Factory factory);
+```
+
+The `factory` argument is a factory callable (move-constructible) object or
+function pointer that creates a new instance of the Test object. It handles
+ownership to the caller. The signature of the callable is `Fixture*()`, where
+`Fixture` is the test fixture class for the test. All tests registered with the
+same `test_suite_name` must return the same fixture type. This is checked at
+runtime.
+
+The framework will infer the fixture class from the factory and will call the
+`SetUpTestSuite` and `TearDownTestSuite` for it.
+
+Must be called before `RUN_ALL_TESTS()` is invoked, otherwise behavior is
+undefined.
+
+Use case example:
+
+```c++
+class MyFixture : public testing::Test {
+ public:
+ // All of these optional, just like in regular macro usage.
+ static void SetUpTestSuite() { ... }
+ static void TearDownTestSuite() { ... }
+ void SetUp() override { ... }
+ void TearDown() override { ... }
+};
+
+class MyTest : public MyFixture {
+ public:
+ explicit MyTest(int data) : data_(data) {}
+ void TestBody() override { ... }
+
+ private:
+ int data_;
+};
+
+void RegisterMyTests(const std::vector<int>& values) {
+ for (int v : values) {
+ testing::RegisterTest(
+ "MyFixture", ("Test" + std::to_string(v)).c_str(), nullptr,
+ std::to_string(v).c_str(),
+ __FILE__, __LINE__,
+ // Important to use the fixture type as the return type here.
+ [=]() -> MyFixture* { return new MyTest(v); });
+ }
+}
+...
+int main(int argc, char** argv) {
+ testing::InitGoogleTest(&argc, argv);
+ std::vector<int> values_to_test = LoadValuesFromConfig();
+ RegisterMyTests(values_to_test);
+ ...
+ return RUN_ALL_TESTS();
+}
+```
+
+## Getting the Current Test's Name
+
+Sometimes a function may need to know the name of the currently running test.
+For example, you may be using the `SetUp()` method of your test fixture to set
+the golden file name based on which test is running. The
+[`TestInfo`](reference/testing.md#TestInfo) class has this information.
+
+To obtain a `TestInfo` object for the currently running test, call
+`current_test_info()` on the [`UnitTest`](reference/testing.md#UnitTest)
+singleton object:
+
+```c++
+ // Gets information about the currently running test.
+ // Do NOT delete the returned object - it's managed by the UnitTest class.
+ const testing::TestInfo* const test_info =
+ testing::UnitTest::GetInstance()->current_test_info();
+
+ printf("We are in test %s of test suite %s.\n",
+ test_info->name(),
+ test_info->test_suite_name());
+```
+
+`current_test_info()` returns a null pointer if no test is running. In
+particular, you cannot find the test suite name in `SetUpTestSuite()`,
+`TearDownTestSuite()` (where you know the test suite name implicitly), or
+functions called from them.
+
+## Extending googletest by Handling Test Events
+
+googletest provides an **event listener API** to let you receive notifications
+about the progress of a test program and test failures. The events you can
+listen to include the start and end of the test program, a test suite, or a test
+method, among others. You may use this API to augment or replace the standard
+console output, replace the XML output, or provide a completely different form
+of output, such as a GUI or a database. You can also use test events as
+checkpoints to implement a resource leak checker, for example.
+
+### Defining Event Listeners
+
+To define a event listener, you subclass either
+[`testing::TestEventListener`](reference/testing.md#TestEventListener) or
+[`testing::EmptyTestEventListener`](reference/testing.md#EmptyTestEventListener)
+The former is an (abstract) interface, where *each pure virtual method can be
+overridden to handle a test event* (For example, when a test starts, the
+`OnTestStart()` method will be called.). The latter provides an empty
+implementation of all methods in the interface, such that a subclass only needs
+to override the methods it cares about.
+
+When an event is fired, its context is passed to the handler function as an
+argument. The following argument types are used:
+
+* UnitTest reflects the state of the entire test program,
+* TestSuite has information about a test suite, which can contain one or more
+ tests,
+* TestInfo contains the state of a test, and
+* TestPartResult represents the result of a test assertion.
+
+An event handler function can examine the argument it receives to find out
+interesting information about the event and the test program's state.
+
+Here's an example:
+
+```c++
+ class MinimalistPrinter : public testing::EmptyTestEventListener {
+ // Called before a test starts.
+ void OnTestStart(const testing::TestInfo& test_info) override {
+ printf("*** Test %s.%s starting.\n",
+ test_info.test_suite_name(), test_info.name());
+ }
+
+ // Called after a failed assertion or a SUCCESS().
+ void OnTestPartResult(const testing::TestPartResult& test_part_result) override {
+ printf("%s in %s:%d\n%s\n",
+ test_part_result.failed() ? "*** Failure" : "Success",
+ test_part_result.file_name(),
+ test_part_result.line_number(),
+ test_part_result.summary());
+ }
+
+ // Called after a test ends.
+ void OnTestEnd(const testing::TestInfo& test_info) override {
+ printf("*** Test %s.%s ending.\n",
+ test_info.test_suite_name(), test_info.name());
+ }
+ };
+```
+
+### Using Event Listeners
+
+To use the event listener you have defined, add an instance of it to the
+googletest event listener list (represented by class
+[`TestEventListeners`](reference/testing.md#TestEventListeners) - note the "s"
+at the end of the name) in your `main()` function, before calling
+`RUN_ALL_TESTS()`:
+
+```c++
+int main(int argc, char** argv) {
+ testing::InitGoogleTest(&argc, argv);
+ // Gets hold of the event listener list.
+ testing::TestEventListeners& listeners =
+ testing::UnitTest::GetInstance()->listeners();
+ // Adds a listener to the end. googletest takes the ownership.
+ listeners.Append(new MinimalistPrinter);
+ return RUN_ALL_TESTS();
+}
+```
+
+There's only one problem: the default test result printer is still in effect, so
+its output will mingle with the output from your minimalist printer. To suppress
+the default printer, just release it from the event listener list and delete it.
+You can do so by adding one line:
+
+```c++
+ ...
+ delete listeners.Release(listeners.default_result_printer());
+ listeners.Append(new MinimalistPrinter);
+ return RUN_ALL_TESTS();
+```
+
+Now, sit back and enjoy a completely different output from your tests. For more
+details, see [sample9_unittest.cc].
+
+[sample9_unittest.cc]: https://github.com/google/googletest/blob/master/googletest/samples/sample9_unittest.cc "Event listener example"
+
+You may append more than one listener to the list. When an `On*Start()` or
+`OnTestPartResult()` event is fired, the listeners will receive it in the order
+they appear in the list (since new listeners are added to the end of the list,
+the default text printer and the default XML generator will receive the event
+first). An `On*End()` event will be received by the listeners in the *reverse*
+order. This allows output by listeners added later to be framed by output from
+listeners added earlier.
+
+### Generating Failures in Listeners
+
+You may use failure-raising macros (`EXPECT_*()`, `ASSERT_*()`, `FAIL()`, etc)
+when processing an event. There are some restrictions:
+
+1. You cannot generate any failure in `OnTestPartResult()` (otherwise it will
+ cause `OnTestPartResult()` to be called recursively).
+2. A listener that handles `OnTestPartResult()` is not allowed to generate any
+ failure.
+
+When you add listeners to the listener list, you should put listeners that
+handle `OnTestPartResult()` *before* listeners that can generate failures. This
+ensures that failures generated by the latter are attributed to the right test
+by the former.
+
+See [sample10_unittest.cc] for an example of a failure-raising listener.
+
+[sample10_unittest.cc]: https://github.com/google/googletest/blob/master/googletest/samples/sample10_unittest.cc "Failure-raising listener example"
+
+## Running Test Programs: Advanced Options
+
+googletest test programs are ordinary executables. Once built, you can run them
+directly and affect their behavior via the following environment variables
+and/or command line flags. For the flags to work, your programs must call
+`::testing::InitGoogleTest()` before calling `RUN_ALL_TESTS()`.
+
+To see a list of supported flags and their usage, please run your test program
+with the `--help` flag. You can also use `-h`, `-?`, or `/?` for short.
+
+If an option is specified both by an environment variable and by a flag, the
+latter takes precedence.
+
+### Selecting Tests
+
+#### Listing Test Names
+
+Sometimes it is necessary to list the available tests in a program before
+running them so that a filter may be applied if needed. Including the flag
+`--gtest_list_tests` overrides all other flags and lists tests in the following
+format:
+
+```none
+TestSuite1.
+ TestName1
+ TestName2
+TestSuite2.
+ TestName
+```
+
+None of the tests listed are actually run if the flag is provided. There is no
+corresponding environment variable for this flag.
+
+#### Running a Subset of the Tests
+
+By default, a googletest program runs all tests the user has defined. Sometimes,
+you want to run only a subset of the tests (e.g. for debugging or quickly
+verifying a change). If you set the `GTEST_FILTER` environment variable or the
+`--gtest_filter` flag to a filter string, googletest will only run the tests
+whose full names (in the form of `TestSuiteName.TestName`) match the filter.
+
+The format of a filter is a '`:`'-separated list of wildcard patterns (called
+the *positive patterns*) optionally followed by a '`-`' and another
+'`:`'-separated pattern list (called the *negative patterns*). A test matches
+the filter if and only if it matches any of the positive patterns but does not
+match any of the negative patterns.
+
+A pattern may contain `'*'` (matches any string) or `'?'` (matches any single
+character). For convenience, the filter `'*-NegativePatterns'` can be also
+written as `'-NegativePatterns'`.
+
+For example:
+
+* `./foo_test` Has no flag, and thus runs all its tests.
+* `./foo_test --gtest_filter=*` Also runs everything, due to the single
+ match-everything `*` value.
+* `./foo_test --gtest_filter=FooTest.*` Runs everything in test suite
+ `FooTest` .
+* `./foo_test --gtest_filter=*Null*:*Constructor*` Runs any test whose full
+ name contains either `"Null"` or `"Constructor"` .
+* `./foo_test --gtest_filter=-*DeathTest.*` Runs all non-death tests.
+* `./foo_test --gtest_filter=FooTest.*-FooTest.Bar` Runs everything in test
+ suite `FooTest` except `FooTest.Bar`.
+* `./foo_test --gtest_filter=FooTest.*:BarTest.*-FooTest.Bar:BarTest.Foo` Runs
+ everything in test suite `FooTest` except `FooTest.Bar` and everything in
+ test suite `BarTest` except `BarTest.Foo`.
+
+#### Stop test execution upon first failure
+
+By default, a googletest program runs all tests the user has defined. In some
+cases (e.g. iterative test development & execution) it may be desirable stop
+test execution upon first failure (trading improved latency for completeness).
+If `GTEST_FAIL_FAST` environment variable or `--gtest_fail_fast` flag is set,
+the test runner will stop execution as soon as the first test failure is found.
+
+#### Temporarily Disabling Tests
+
+If you have a broken test that you cannot fix right away, you can add the
+`DISABLED_` prefix to its name. This will exclude it from execution. This is
+better than commenting out the code or using `#if 0`, as disabled tests are
+still compiled (and thus won't rot).
+
+If you need to disable all tests in a test suite, you can either add `DISABLED_`
+to the front of the name of each test, or alternatively add it to the front of
+the test suite name.
+
+For example, the following tests won't be run by googletest, even though they
+will still be compiled:
+
+```c++
+// Tests that Foo does Abc.
+TEST(FooTest, DISABLED_DoesAbc) { ... }
+
+class DISABLED_BarTest : public testing::Test { ... };
+
+// Tests that Bar does Xyz.
+TEST_F(DISABLED_BarTest, DoesXyz) { ... }
+```
+
+{: .callout .note}
+NOTE: This feature should only be used for temporary pain-relief. You still have
+to fix the disabled tests at a later date. As a reminder, googletest will print
+a banner warning you if a test program contains any disabled tests.
+
+{: .callout .tip}
+TIP: You can easily count the number of disabled tests you have using
+`grep`. This number can be used as a metric for
+improving your test quality.
+
+#### Temporarily Enabling Disabled Tests
+
+To include disabled tests in test execution, just invoke the test program with
+the `--gtest_also_run_disabled_tests` flag or set the
+`GTEST_ALSO_RUN_DISABLED_TESTS` environment variable to a value other than `0`.
+You can combine this with the `--gtest_filter` flag to further select which
+disabled tests to run.
+
+### Repeating the Tests
+
+Once in a while you'll run into a test whose result is hit-or-miss. Perhaps it
+will fail only 1% of the time, making it rather hard to reproduce the bug under
+a debugger. This can be a major source of frustration.
+
+The `--gtest_repeat` flag allows you to repeat all (or selected) test methods in
+a program many times. Hopefully, a flaky test will eventually fail and give you
+a chance to debug. Here's how to use it:
+
+```none
+$ foo_test --gtest_repeat=1000
+Repeat foo_test 1000 times and don't stop at failures.
+
+$ foo_test --gtest_repeat=-1
+A negative count means repeating forever.
+
+$ foo_test --gtest_repeat=1000 --gtest_break_on_failure
+Repeat foo_test 1000 times, stopping at the first failure. This
+is especially useful when running under a debugger: when the test
+fails, it will drop into the debugger and you can then inspect
+variables and stacks.
+
+$ foo_test --gtest_repeat=1000 --gtest_filter=FooBar.*
+Repeat the tests whose name matches the filter 1000 times.
+```
+
+If your test program contains
+[global set-up/tear-down](#global-set-up-and-tear-down) code, it will be
+repeated in each iteration as well, as the flakiness may be in it. You can also
+specify the repeat count by setting the `GTEST_REPEAT` environment variable.
+
+### Shuffling the Tests
+
+You can specify the `--gtest_shuffle` flag (or set the `GTEST_SHUFFLE`
+environment variable to `1`) to run the tests in a program in a random order.
+This helps to reveal bad dependencies between tests.
+
+By default, googletest uses a random seed calculated from the current time.
+Therefore you'll get a different order every time. The console output includes
+the random seed value, such that you can reproduce an order-related test failure
+later. To specify the random seed explicitly, use the `--gtest_random_seed=SEED`
+flag (or set the `GTEST_RANDOM_SEED` environment variable), where `SEED` is an
+integer in the range [0, 99999]. The seed value 0 is special: it tells
+googletest to do the default behavior of calculating the seed from the current
+time.
+
+If you combine this with `--gtest_repeat=N`, googletest will pick a different
+random seed and re-shuffle the tests in each iteration.
+
+### Distributing Test Functions to Multiple Machines
+
+If you have more than one machine you can use to run a test program, you might
+want to run the test functions in parallel and get the result faster. We call
+this technique *sharding*, where each machine is called a *shard*.
+
+GoogleTest is compatible with test sharding. To take advantage of this feature,
+your test runner (not part of GoogleTest) needs to do the following:
+
+1. Allocate a number of machines (shards) to run the tests.
+1. On each shard, set the `GTEST_TOTAL_SHARDS` environment variable to the total
+ number of shards. It must be the same for all shards.
+1. On each shard, set the `GTEST_SHARD_INDEX` environment variable to the index
+ of the shard. Different shards must be assigned different indices, which
+ must be in the range `[0, GTEST_TOTAL_SHARDS - 1]`.
+1. Run the same test program on all shards. When GoogleTest sees the above two
+ environment variables, it will select a subset of the test functions to run.
+ Across all shards, each test function in the program will be run exactly
+ once.
+1. Wait for all shards to finish, then collect and report the results.
+
+Your project may have tests that were written without GoogleTest and thus don't
+understand this protocol. In order for your test runner to figure out which test
+supports sharding, it can set the environment variable `GTEST_SHARD_STATUS_FILE`
+to a non-existent file path. If a test program supports sharding, it will create
+this file to acknowledge that fact; otherwise it will not create it. The actual
+contents of the file are not important at this time, although we may put some
+useful information in it in the future.
+
+Here's an example to make it clear. Suppose you have a test program `foo_test`
+that contains the following 5 test functions:
+
+```
+TEST(A, V)
+TEST(A, W)
+TEST(B, X)
+TEST(B, Y)
+TEST(B, Z)
+```
+
+Suppose you have 3 machines at your disposal. To run the test functions in
+parallel, you would set `GTEST_TOTAL_SHARDS` to 3 on all machines, and set
+`GTEST_SHARD_INDEX` to 0, 1, and 2 on the machines respectively. Then you would
+run the same `foo_test` on each machine.
+
+GoogleTest reserves the right to change how the work is distributed across the
+shards, but here's one possible scenario:
+
+* Machine #0 runs `A.V` and `B.X`.
+* Machine #1 runs `A.W` and `B.Y`.
+* Machine #2 runs `B.Z`.
+
+### Controlling Test Output
+
+#### Colored Terminal Output
+
+googletest can use colors in its terminal output to make it easier to spot the
+important information:
+
+<pre>...
+<font color="green">[----------]</font> 1 test from FooTest
+<font color="green">[ RUN ]</font> FooTest.DoesAbc
+<font color="green">[ OK ]</font> FooTest.DoesAbc
+<font color="green">[----------]</font> 2 tests from BarTest
+<font color="green">[ RUN ]</font> BarTest.HasXyzProperty
+<font color="green">[ OK ]</font> BarTest.HasXyzProperty
+<font color="green">[ RUN ]</font> BarTest.ReturnsTrueOnSuccess
+... some error messages ...
+<font color="red">[ FAILED ]</font> BarTest.ReturnsTrueOnSuccess
+...
+<font color="green">[==========]</font> 30 tests from 14 test suites ran.
+<font color="green">[ PASSED ]</font> 28 tests.
+<font color="red">[ FAILED ]</font> 2 tests, listed below:
+<font color="red">[ FAILED ]</font> BarTest.ReturnsTrueOnSuccess
+<font color="red">[ FAILED ]</font> AnotherTest.DoesXyz
+
+ 2 FAILED TESTS
+</pre>
+
+You can set the `GTEST_COLOR` environment variable or the `--gtest_color`
+command line flag to `yes`, `no`, or `auto` (the default) to enable colors,
+disable colors, or let googletest decide. When the value is `auto`, googletest
+will use colors if and only if the output goes to a terminal and (on non-Windows
+platforms) the `TERM` environment variable is set to `xterm` or `xterm-color`.
+
+#### Suppressing test passes
+
+By default, googletest prints 1 line of output for each test, indicating if it
+passed or failed. To show only test failures, run the test program with
+`--gtest_brief=1`, or set the GTEST_BRIEF environment variable to `1`.
+
+#### Suppressing the Elapsed Time
+
+By default, googletest prints the time it takes to run each test. To disable
+that, run the test program with the `--gtest_print_time=0` command line flag, or
+set the GTEST_PRINT_TIME environment variable to `0`.
+
+#### Suppressing UTF-8 Text Output
+
+In case of assertion failures, googletest prints expected and actual values of
+type `string` both as hex-encoded strings as well as in readable UTF-8 text if
+they contain valid non-ASCII UTF-8 characters. If you want to suppress the UTF-8
+text because, for example, you don't have an UTF-8 compatible output medium, run
+the test program with `--gtest_print_utf8=0` or set the `GTEST_PRINT_UTF8`
+environment variable to `0`.
+
+#### Generating an XML Report
+
+googletest can emit a detailed XML report to a file in addition to its normal
+textual output. The report contains the duration of each test, and thus can help
+you identify slow tests.
+
+To generate the XML report, set the `GTEST_OUTPUT` environment variable or the
+`--gtest_output` flag to the string `"xml:path_to_output_file"`, which will
+create the file at the given location. You can also just use the string `"xml"`,
+in which case the output can be found in the `test_detail.xml` file in the
+current directory.
+
+If you specify a directory (for example, `"xml:output/directory/"` on Linux or
+`"xml:output\directory\"` on Windows), googletest will create the XML file in
+that directory, named after the test executable (e.g. `foo_test.xml` for test
+program `foo_test` or `foo_test.exe`). If the file already exists (perhaps left
+over from a previous run), googletest will pick a different name (e.g.
+`foo_test_1.xml`) to avoid overwriting it.
+
+The report is based on the `junitreport` Ant task. Since that format was
+originally intended for Java, a little interpretation is required to make it
+apply to googletest tests, as shown here:
+
+```xml
+<testsuites name="AllTests" ...>
+ <testsuite name="test_case_name" ...>
+ <testcase name="test_name" ...>
+ <failure message="..."/>
+ <failure message="..."/>
+ <failure message="..."/>
+ </testcase>
+ </testsuite>
+</testsuites>
+```
+
+* The root `<testsuites>` element corresponds to the entire test program.
+* `<testsuite>` elements correspond to googletest test suites.
+* `<testcase>` elements correspond to googletest test functions.
+
+For instance, the following program
+
+```c++
+TEST(MathTest, Addition) { ... }
+TEST(MathTest, Subtraction) { ... }
+TEST(LogicTest, NonContradiction) { ... }
+```
+
+could generate this report:
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<testsuites tests="3" failures="1" errors="0" time="0.035" timestamp="2011-10-31T18:52:42" name="AllTests">
+ <testsuite name="MathTest" tests="2" failures="1" errors="0" time="0.015">
+ <testcase name="Addition" status="run" time="0.007" classname="">
+ <failure message="Value of: add(1, 1)&#x0A; Actual: 3&#x0A;Expected: 2" type="">...</failure>
+ <failure message="Value of: add(1, -1)&#x0A; Actual: 1&#x0A;Expected: 0" type="">...</failure>
+ </testcase>
+ <testcase name="Subtraction" status="run" time="0.005" classname="">
+ </testcase>
+ </testsuite>
+ <testsuite name="LogicTest" tests="1" failures="0" errors="0" time="0.005">
+ <testcase name="NonContradiction" status="run" time="0.005" classname="">
+ </testcase>
+ </testsuite>
+</testsuites>
+```
+
+Things to note:
+
+* The `tests` attribute of a `<testsuites>` or `<testsuite>` element tells how
+ many test functions the googletest program or test suite contains, while the
+ `failures` attribute tells how many of them failed.
+
+* The `time` attribute expresses the duration of the test, test suite, or
+ entire test program in seconds.
+
+* The `timestamp` attribute records the local date and time of the test
+ execution.
+
+* Each `<failure>` element corresponds to a single failed googletest
+ assertion.
+
+#### Generating a JSON Report
+
+googletest can also emit a JSON report as an alternative format to XML. To
+generate the JSON report, set the `GTEST_OUTPUT` environment variable or the
+`--gtest_output` flag to the string `"json:path_to_output_file"`, which will
+create the file at the given location. You can also just use the string
+`"json"`, in which case the output can be found in the `test_detail.json` file
+in the current directory.
+
+The report format conforms to the following JSON Schema:
+
+```json
+{
+ "$schema": "http://json-schema.org/schema#",
+ "type": "object",
+ "definitions": {
+ "TestCase": {

+
+The report uses the format that conforms to the following Proto3 using the
+[JSON encoding](https://developers.google.com/protocol-buffers/docs/proto3#json):
+
+```proto

+import "google/protobuf/duration.proto";
+

+
+### Controlling How Failures Are Reported
+
+#### Detecting Test Premature Exit
+
+Google Test implements the _premature-exit-file_ protocol for test runners to
+catch any kind of unexpected exits of test programs. Upon start, Google Test
+creates the file which will be automatically deleted after all work has been
+finished. Then, the test runner can check if this file exists. In case the file
+remains undeleted, the inspected test has exited prematurely.
+
+This feature is enabled only if the `TEST_PREMATURE_EXIT_FILE` environment
+variable has been set.
+
+#### Turning Assertion Failures into Break-Points
+
+When running test programs under a debugger, it's very convenient if the
+debugger can catch an assertion failure and automatically drop into interactive
+mode. googletest's *break-on-failure* mode supports this behavior.
+
+To enable it, set the `GTEST_BREAK_ON_FAILURE` environment variable to a value
+other than `0`. Alternatively, you can use the `--gtest_break_on_failure`
+command line flag.
+
+#### Disabling Catching Test-Thrown Exceptions
+
+googletest can be used either with or without exceptions enabled. If a test
+throws a C++ exception or (on Windows) a structured exception (SEH), by default
+googletest catches it, reports it as a test failure, and continues with the next
+test method. This maximizes the coverage of a test run. Also, on Windows an
+uncaught exception will cause a pop-up window, so catching the exceptions allows
+you to run the tests automatically.
+
+When debugging the test failures, however, you may instead want the exceptions
+to be handled by the debugger, such that you can examine the call stack when an
+exception is thrown. To achieve that, set the `GTEST_CATCH_EXCEPTIONS`
+environment variable to `0`, or use the `--gtest_catch_exceptions=0` flag when
+running the tests.
+
+### Sanitizer Integration
+
+The
+[Undefined Behavior Sanitizer](https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html),
+[Address Sanitizer](https://github.com/google/sanitizers/wiki/AddressSanitizer),
+and
+[Thread Sanitizer](https://github.com/google/sanitizers/wiki/ThreadSanitizerCppManual)
+all provide weak functions that you can override to trigger explicit failures
+when they detect sanitizer errors, such as creating a reference from `nullptr`.
+To override these functions, place definitions for them in a source file that
+you compile as part of your main binary:
+
+```
+extern "C" {
+void __ubsan_on_report() {
+ FAIL() << "Encountered an undefined behavior sanitizer error";
+}
+void __asan_on_error() {
+ FAIL() << "Encountered an address sanitizer error";
+}
+void __tsan_on_report() {
+ FAIL() << "Encountered a thread sanitizer error";
+}
+} // extern "C"
+```
+
+After compiling your project with one of the sanitizers enabled, if a particular
+test triggers a sanitizer error, googletest will report that it failed.

+# Googletest FAQ
+
+## Why should test suite names and test names not contain underscore?
+
+{: .callout .note}
+Note: Googletest reserves underscore (`_`) for special purpose keywords, such as
+[the `DISABLED_` prefix](advanced.md#temporarily-disabling-tests), in addition
+to the following rationale.
+
+Underscore (`_`) is special, as C++ reserves the following to be used by the
+compiler and the standard library:
+
+1. any identifier that starts with an `_` followed by an upper-case letter, and
+2. any identifier that contains two consecutive underscores (i.e. `__`)
+ *anywhere* in its name.
+
+User code is *prohibited* from using such identifiers.
+
+Now let's look at what this means for `TEST` and `TEST_F`.
+
+Currently `TEST(TestSuiteName, TestName)` generates a class named
+`TestSuiteName_TestName_Test`. What happens if `TestSuiteName` or `TestName`
+contains `_`?
+
+1. If `TestSuiteName` starts with an `_` followed by an upper-case letter (say,
+ `_Foo`), we end up with `_Foo_TestName_Test`, which is reserved and thus
+ invalid.
+2. If `TestSuiteName` ends with an `_` (say, `Foo_`), we get
+ `Foo__TestName_Test`, which is invalid.
+3. If `TestName` starts with an `_` (say, `_Bar`), we get
+ `TestSuiteName__Bar_Test`, which is invalid.
+4. If `TestName` ends with an `_` (say, `Bar_`), we get
+ `TestSuiteName_Bar__Test`, which is invalid.
+
+So clearly `TestSuiteName` and `TestName` cannot start or end with `_`
+(Actually, `TestSuiteName` can start with `_` -- as long as the `_` isn't
+followed by an upper-case letter. But that's getting complicated. So for
+simplicity we just say that it cannot start with `_`.).
+
+It may seem fine for `TestSuiteName` and `TestName` to contain `_` in the
+middle. However, consider this:
+
+```c++
+TEST(Time, Flies_Like_An_Arrow) { ... }
+TEST(Time_Flies, Like_An_Arrow) { ... }
+```
+
+Now, the two `TEST`s will both generate the same class
+(`Time_Flies_Like_An_Arrow_Test`). That's not good.
+
+So for simplicity, we just ask the users to avoid `_` in `TestSuiteName` and
+`TestName`. The rule is more constraining than necessary, but it's simple and
+easy to remember. It also gives googletest some wiggle room in case its
+implementation needs to change in the future.
+
+If you violate the rule, there may not be immediate consequences, but your test
+may (just may) break with a new compiler (or a new version of the compiler you
+are using) or with a new version of googletest. Therefore it's best to follow
+the rule.
+
+## Why does googletest support `EXPECT_EQ(NULL, ptr)` and `ASSERT_EQ(NULL, ptr)` but not `EXPECT_NE(NULL, ptr)` and `ASSERT_NE(NULL, ptr)`?
+
+First of all, you can use `nullptr` with each of these macros, e.g.
+`EXPECT_EQ(ptr, nullptr)`, `EXPECT_NE(ptr, nullptr)`, `ASSERT_EQ(ptr, nullptr)`,
+`ASSERT_NE(ptr, nullptr)`. This is the preferred syntax in the style guide
+because `nullptr` does not have the type problems that `NULL` does.
+
+Due to some peculiarity of C++, it requires some non-trivial template meta
+programming tricks to support using `NULL` as an argument of the `EXPECT_XX()`
+and `ASSERT_XX()` macros. Therefore we only do it where it's most needed
+(otherwise we make the implementation of googletest harder to maintain and more
+error-prone than necessary).
+
+Historically, the `EXPECT_EQ()` macro took the *expected* value as its first
+argument and the *actual* value as the second, though this argument order is now
+discouraged. It was reasonable that someone wanted
+to write `EXPECT_EQ(NULL, some_expression)`, and this indeed was requested
+several times. Therefore we implemented it.
+
+The need for `EXPECT_NE(NULL, ptr)` wasn't nearly as strong. When the assertion
+fails, you already know that `ptr` must be `NULL`, so it doesn't add any
+information to print `ptr` in this case. That means `EXPECT_TRUE(ptr != NULL)`
+works just as well.
+
+If we were to support `EXPECT_NE(NULL, ptr)`, for consistency we'd have to
+support `EXPECT_NE(ptr, NULL)` as well. This means using the template meta
+programming tricks twice in the implementation, making it even harder to
+understand and maintain. We believe the benefit doesn't justify the cost.
+
+Finally, with the growth of the gMock matcher library, we are encouraging people
+to use the unified `EXPECT_THAT(value, matcher)` syntax more often in tests. One
+significant advantage of the matcher approach is that matchers can be easily
+combined to form new matchers, while the `EXPECT_NE`, etc, macros cannot be
+easily combined. Therefore we want to invest more in the matchers than in the
+`EXPECT_XX()` macros.
+
+## I need to test that different implementations of an interface satisfy some common requirements. Should I use typed tests or value-parameterized tests?
+
+For testing various implementations of the same interface, either typed tests or
+value-parameterized tests can get it done. It's really up to you the user to
+decide which is more convenient for you, depending on your particular case. Some
+rough guidelines:
+
+* Typed tests can be easier to write if instances of the different
+ implementations can be created the same way, modulo the type. For example,
+ if all these implementations have a public default constructor (such that
+ you can write `new TypeParam`), or if their factory functions have the same
+ form (e.g. `CreateInstance<TypeParam>()`).
+* Value-parameterized tests can be easier to write if you need different code
+ patterns to create different implementations' instances, e.g. `new Foo` vs
+ `new Bar(5)`. To accommodate for the differences, you can write factory
+ function wrappers and pass these function pointers to the tests as their
+ parameters.
+* When a typed test fails, the default output includes the name of the type,
+ which can help you quickly identify which implementation is wrong.
+ Value-parameterized tests only show the number of the failed iteration by
+ default. You will need to define a function that returns the iteration name
+ and pass it as the third parameter to INSTANTIATE_TEST_SUITE_P to have more
+ useful output.
+* When using typed tests, you need to make sure you are testing against the
+ interface type, not the concrete types (in other words, you want to make
+ sure `implicit_cast<MyInterface*>(my_concrete_impl)` works, not just that
+ `my_concrete_impl` works). It's less likely to make mistakes in this area
+ when using value-parameterized tests.
+
+I hope I didn't confuse you more. :-) If you don't mind, I'd suggest you to give
+both approaches a try. Practice is a much better way to grasp the subtle
+differences between the two tools. Once you have some concrete experience, you
+can much more easily decide which one to use the next time.
+
+## I got some run-time errors about invalid proto descriptors when using `ProtocolMessageEquals`. Help!
+
+{: .callout .note}
+**Note:** `ProtocolMessageEquals` and `ProtocolMessageEquiv` are *deprecated*
+now. Please use `EqualsProto`, etc instead.
+
+`ProtocolMessageEquals` and `ProtocolMessageEquiv` were redefined recently and
+are now less tolerant of invalid protocol buffer definitions. In particular, if
+you have a `foo.proto` that doesn't fully qualify the type of a protocol message
+it references (e.g. `message<Bar>` where it should be `message<blah.Bar>`), you
+will now get run-time errors like:
+
+```
+... descriptor.cc:...] Invalid proto descriptor for file "path/to/foo.proto":
+... descriptor.cc:...] blah.MyMessage.my_field: ".Bar" is not defined.
+```
+
+If you see this, your `.proto` file is broken and needs to be fixed by making
+the types fully qualified. The new definition of `ProtocolMessageEquals` and
+`ProtocolMessageEquiv` just happen to reveal your bug.
+
+## My death test modifies some state, but the change seems lost after the death test finishes. Why?
+
+Death tests (`EXPECT_DEATH`, etc) are executed in a sub-process s.t. the
+expected crash won't kill the test program (i.e. the parent process). As a
+result, any in-memory side effects they incur are observable in their respective
+sub-processes, but not in the parent process. You can think of them as running
+in a parallel universe, more or less.
+
+In particular, if you use mocking and the death test statement invokes some mock
+methods, the parent process will think the calls have never occurred. Therefore,
+you may want to move your `EXPECT_CALL` statements inside the `EXPECT_DEATH`
+macro.
+
+## EXPECT_EQ(htonl(blah), blah_blah) generates weird compiler errors in opt mode. Is this a googletest bug?
+
+Actually, the bug is in `htonl()`.
+
+According to `'man htonl'`, `htonl()` is a *function*, which means it's valid to
+use `htonl` as a function pointer. However, in opt mode `htonl()` is defined as
+a *macro*, which breaks this usage.
+
+Worse, the macro definition of `htonl()` uses a `gcc` extension and is *not*
+standard C++. That hacky implementation has some ad hoc limitations. In
+particular, it prevents you from writing `Foo<sizeof(htonl(x))>()`, where `Foo`
+is a template that has an integral argument.
+
+The implementation of `EXPECT_EQ(a, b)` uses `sizeof(... a ...)` inside a
+template argument, and thus doesn't compile in opt mode when `a` contains a call
+to `htonl()`. It is difficult to make `EXPECT_EQ` bypass the `htonl()` bug, as
+the solution must work with different compilers on various platforms.
+
+## The compiler complains about "undefined references" to some static const member variables, but I did define them in the class body. What's wrong?
+
+If your class has a static data member:
+
+```c++
+// foo.h
+class Foo {
+ ...
+ static const int kBar = 100;
+};
+```
+
+You also need to define it *outside* of the class body in `foo.cc`:
+
+```c++
+const int Foo::kBar; // No initializer here.
+```
+
+Otherwise your code is **invalid C++**, and may break in unexpected ways. In
+particular, using it in googletest comparison assertions (`EXPECT_EQ`, etc) will
+generate an "undefined reference" linker error. The fact that "it used to work"
+doesn't mean it's valid. It just means that you were lucky. :-)
+
+If the declaration of the static data member is `constexpr` then it is
+implicitly an `inline` definition, and a separate definition in `foo.cc` is not
+needed:
+
+```c++
+// foo.h
+class Foo {
+ ...
+ static constexpr int kBar = 100; // Defines kBar, no need to do it in foo.cc.
+};
+```
+
+## Can I derive a test fixture from another?
+
+Yes.
+
+Each test fixture has a corresponding and same named test suite. This means only
+one test suite can use a particular fixture. Sometimes, however, multiple test
+cases may want to use the same or slightly different fixtures. For example, you
+may want to make sure that all of a GUI library's test suites don't leak
+important system resources like fonts and brushes.
+
+In googletest, you share a fixture among test suites by putting the shared logic
+in a base test fixture, then deriving from that base a separate fixture for each
+test suite that wants to use this common logic. You then use `TEST_F()` to write
+tests using each derived fixture.
+
+Typically, your code looks like this:
+
+```c++
+// Defines a base test fixture.
+class BaseTest : public ::testing::Test {
+ protected:
+ ...
+};
+
+// Derives a fixture FooTest from BaseTest.
+class FooTest : public BaseTest {
+ protected:
+ void SetUp() override {
+ BaseTest::SetUp(); // Sets up the base fixture first.
+ ... additional set-up work ...
+ }
+
+ void TearDown() override {
+ ... clean-up work for FooTest ...
+ BaseTest::TearDown(); // Remember to tear down the base fixture
+ // after cleaning up FooTest!
+ }
+
+ ... functions and variables for FooTest ...
+};
+
+// Tests that use the fixture FooTest.
+TEST_F(FooTest, Bar) { ... }
+TEST_F(FooTest, Baz) { ... }
+
+... additional fixtures derived from BaseTest ...
+```
+
+If necessary, you can continue to derive test fixtures from a derived fixture.
+googletest has no limit on how deep the hierarchy can be.
+
+For a complete example using derived test fixtures, see
+[sample5_unittest.cc](https://github.com/google/googletest/blob/master/googletest/samples/sample5_unittest.cc).
+
+## My compiler complains "void value not ignored as it ought to be." What does this mean?
+
+You're probably using an `ASSERT_*()` in a function that doesn't return `void`.
+`ASSERT_*()` can only be used in `void` functions, due to exceptions being
+disabled by our build system. Please see more details
+[here](advanced.md#assertion-placement).
+
+## My death test hangs (or seg-faults). How do I fix it?
+
+In googletest, death tests are run in a child process and the way they work is
+delicate. To write death tests you really need to understand how they work—see
+the details at [Death Assertions](reference/assertions.md#death) in the
+Assertions Reference.
+
+In particular, death tests don't like having multiple threads in the parent
+process. So the first thing you can try is to eliminate creating threads outside
+of `EXPECT_DEATH()`. For example, you may want to use mocks or fake objects
+instead of real ones in your tests.
+
+Sometimes this is impossible as some library you must use may be creating
+threads before `main()` is even reached. In this case, you can try to minimize
+the chance of conflicts by either moving as many activities as possible inside
+`EXPECT_DEATH()` (in the extreme case, you want to move everything inside), or
+leaving as few things as possible in it. Also, you can try to set the death test
+style to `"threadsafe"`, which is safer but slower, and see if it helps.
+
+If you go with thread-safe death tests, remember that they rerun the test
+program from the beginning in the child process. Therefore make sure your
+program can run side-by-side with itself and is deterministic.
+
+In the end, this boils down to good concurrent programming. You have to make
+sure that there are no race conditions or deadlocks in your program. No silver
+bullet - sorry!

+The first thing to remember is that googletest does **not** reuse the same test
+fixture object across multiple tests. For each `TEST_F`, googletest will create
+a **fresh** test fixture object, immediately call `SetUp()`, run the test body,
+call `TearDown()`, and then delete the test fixture object.
+
+When you need to write per-test set-up and tear-down logic, you have the choice
+between using the test fixture constructor/destructor or `SetUp()/TearDown()`.
+The former is usually preferred, as it has the following benefits:
+
+* By initializing a member variable in the constructor, we have the option to
+ make it `const`, which helps prevent accidental changes to its value and
+ makes the tests more obviously correct.
+* In case we need to subclass the test fixture class, the subclass'
+ constructor is guaranteed to call the base class' constructor *first*, and
+ the subclass' destructor is guaranteed to call the base class' destructor
+ *afterward*. With `SetUp()/TearDown()`, a subclass may make the mistake of
+ forgetting to call the base class' `SetUp()/TearDown()` or call them at the
+ wrong time.
+
+You may still want to use `SetUp()/TearDown()` in the following cases:
+
+* C++ does not allow virtual function calls in constructors and destructors.
+ You can call a method declared as virtual, but it will not use dynamic
+ dispatch. It will use the definition from the class the constructor of which
+ is currently executing. This is because calling a virtual method before the
+ derived class constructor has a chance to run is very dangerous - the
+ virtual method might operate on uninitialized data. Therefore, if you need
+ to call a method that will be overridden in a derived class, you have to use
+ `SetUp()/TearDown()`.
+* In the body of a constructor (or destructor), it's not possible to use the
+ `ASSERT_xx` macros. Therefore, if the set-up operation could cause a fatal
+ test failure that should prevent the test from running, it's necessary to
+ use `abort` and abort the whole test
+ executable, or to use `SetUp()` instead of a constructor.
+* If the tear-down operation could throw an exception, you must use
+ `TearDown()` as opposed to the destructor, as throwing in a destructor leads
+ to undefined behavior and usually will kill your program right away. Note
+ that many standard libraries (like STL) may throw when exceptions are
+ enabled in the compiler. Therefore you should prefer `TearDown()` if you
+ want to write portable tests that work with or without exceptions.
+* The googletest team is considering making the assertion macros throw on
+ platforms where exceptions are enabled (e.g. Windows, Mac OS, and Linux
+ client-side), which will eliminate the need for the user to propagate
+ failures from a subroutine to its caller. Therefore, you shouldn't use
+ googletest assertions in a destructor if your code could run on such a
+ platform.
+
+## The compiler complains "no matching function to call" when I use ASSERT_PRED*. How do I fix it?
+
+See details for [`EXPECT_PRED*`](reference/assertions.md#EXPECT_PRED) in the
+Assertions Reference.
+
+## My compiler complains about "ignoring return value" when I call RUN_ALL_TESTS(). Why?
+
+Some people had been ignoring the return value of `RUN_ALL_TESTS()`. That is,
+instead of
+
+```c++
+ return RUN_ALL_TESTS();
+```
+
+they write
+
+```c++
+ RUN_ALL_TESTS();
+```
+
+This is **wrong and dangerous**. The testing services needs to see the return
+value of `RUN_ALL_TESTS()` in order to determine if a test has passed. If your
+`main()` function ignores it, your test will be considered successful even if it
+has a googletest assertion failure. Very bad.
+
+We have decided to fix this (thanks to Michael Chastain for the idea). Now, your
+code will no longer be able to ignore `RUN_ALL_TESTS()` when compiled with
+`gcc`. If you do so, you'll get a compiler error.
+
+If you see the compiler complaining about you ignoring the return value of
+`RUN_ALL_TESTS()`, the fix is simple: just make sure its value is used as the
+return value of `main()`.
+
+But how could we introduce a change that breaks existing tests? Well, in this
+case, the code was already broken in the first place, so we didn't break it. :-)
+
+## My compiler complains that a constructor (or destructor) cannot return a value. What's going on?
+
+Due to a peculiarity of C++, in order to support the syntax for streaming
+messages to an `ASSERT_*`, e.g.
+
+```c++
+ ASSERT_EQ(1, Foo()) << "blah blah" << foo;
+```
+
+we had to give up using `ASSERT*` and `FAIL*` (but not `EXPECT*` and
+`ADD_FAILURE*`) in constructors and destructors. The workaround is to move the
+content of your constructor/destructor to a private void member function, or
+switch to `EXPECT_*()` if that works. This
+[section](advanced.md#assertion-placement) in the user's guide explains it.
+
+## My SetUp() function is not called. Why?
+
+C++ is case-sensitive. Did you spell it as `Setup()`?
+
+Similarly, sometimes people spell `SetUpTestSuite()` as `SetupTestSuite()` and
+wonder why it's never called.
+
+## I have several test suites which share the same test fixture logic, do I have to define a new test fixture class for each of them? This seems pretty tedious.
+
+You don't have to. Instead of
+
+```c++
+class FooTest : public BaseTest {};
+
+TEST_F(FooTest, Abc) { ... }
+TEST_F(FooTest, Def) { ... }
+
+class BarTest : public BaseTest {};
+
+TEST_F(BarTest, Abc) { ... }
+TEST_F(BarTest, Def) { ... }
+```
+
+you can simply `typedef` the test fixtures:
+
+```c++
+typedef BaseTest FooTest;
+
+TEST_F(FooTest, Abc) { ... }
+TEST_F(FooTest, Def) { ... }
+
+typedef BaseTest BarTest;
+
+TEST_F(BarTest, Abc) { ... }
+TEST_F(BarTest, Def) { ... }
+```
+
+## googletest output is buried in a whole bunch of LOG messages. What do I do?
+
+The googletest output is meant to be a concise and human-friendly report. If
+your test generates textual output itself, it will mix with the googletest
+output, making it hard to read. However, there is an easy solution to this
+problem.
+
+Since `LOG` messages go to stderr, we decided to let googletest output go to
+stdout. This way, you can easily separate the two using redirection. For
+example:
+
+```shell
+$ ./my_test > gtest_output.txt
+```
+
+## Why should I prefer test fixtures over global variables?
+
+There are several good reasons:
+
+1. It's likely your test needs to change the states of its global variables.
+ This makes it difficult to keep side effects from escaping one test and
+ contaminating others, making debugging difficult. By using fixtures, each
+ test has a fresh set of variables that's different (but with the same
+ names). Thus, tests are kept independent of each other.
+2. Global variables pollute the global namespace.
+3. Test fixtures can be reused via subclassing, which cannot be done easily
+ with global variables. This is useful if many test suites have something in
+ common.
+
+## What can the statement argument in ASSERT_DEATH() be?
+
+`ASSERT_DEATH(statement, matcher)` (or any death assertion macro) can be used
+wherever *`statement`* is valid. So basically *`statement`* can be any C++
+statement that makes sense in the current context. In particular, it can
+reference global and/or local variables, and can be:
+
+* a simple function call (often the case),
+* a complex expression, or
+* a compound statement.
+
+Some examples are shown here:
+
+```c++
+// A death test can be a simple function call.
+TEST(MyDeathTest, FunctionCall) {
+ ASSERT_DEATH(Xyz(5), "Xyz failed");
+}
+
+// Or a complex expression that references variables and functions.
+TEST(MyDeathTest, ComplexExpression) {
+ const bool c = Condition();
+ ASSERT_DEATH((c ? Func1(0) : object2.Method("test")),
+ "(Func1|Method) failed");
+}
+
+// Death assertions can be used anywhere in a function. In
+// particular, they can be inside a loop.
+TEST(MyDeathTest, InsideLoop) {
+ // Verifies that Foo(0), Foo(1), ..., and Foo(4) all die.
+ for (int i = 0; i < 5; i++) {
+ EXPECT_DEATH_M(Foo(i), "Foo has \\d+ errors",
+ ::testing::Message() << "where i is " << i);
+ }
+}
+
+// A death assertion can contain a compound statement.
+TEST(MyDeathTest, CompoundStatement) {
+ // Verifies that at lease one of Bar(0), Bar(1), ..., and
+ // Bar(4) dies.
+ ASSERT_DEATH({
+ for (int i = 0; i < 5; i++) {
+ Bar(i);
+ }
+ },
+ "Bar has \\d+ errors");
+}
+```
+
+## I have a fixture class `FooTest`, but `TEST_F(FooTest, Bar)` gives me error ``"no matching function for call to `FooTest::FooTest()'"``. Why?
+
+Googletest needs to be able to create objects of your test fixture class, so it
+must have a default constructor. Normally the compiler will define one for you.
+However, there are cases where you have to define your own:
+
+* If you explicitly declare a non-default constructor for class `FooTest`
+ (`DISALLOW_EVIL_CONSTRUCTORS()` does this), then you need to define a
+ default constructor, even if it would be empty.
+* If `FooTest` has a const non-static data member, then you have to define the
+ default constructor *and* initialize the const member in the initializer
+ list of the constructor. (Early versions of `gcc` doesn't force you to
+ initialize the const member. It's a bug that has been fixed in `gcc 4`.)
+
+## Why does ASSERT_DEATH complain about previous threads that were already joined?
+
+With the Linux pthread library, there is no turning back once you cross the line
+from a single thread to multiple threads. The first time you create a thread, a
+manager thread is created in addition, so you get 3, not 2, threads. Later when
+the thread you create joins the main thread, the thread count decrements by 1,
+but the manager thread will never be killed, so you still have 2 threads, which
+means you cannot safely run a death test.
+
+The new NPTL thread library doesn't suffer from this problem, as it doesn't
+create a manager thread. However, if you don't control which machine your test
+runs on, you shouldn't depend on this.
+
+## Why does googletest require the entire test suite, instead of individual tests, to be named *DeathTest when it uses ASSERT_DEATH?
+
+googletest does not interleave tests from different test suites. That is, it
+runs all tests in one test suite first, and then runs all tests in the next test
+suite, and so on. googletest does this because it needs to set up a test suite
+before the first test in it is run, and tear it down afterwards. Splitting up
+the test case would require multiple set-up and tear-down processes, which is
+inefficient and makes the semantics unclean.
+
+If we were to determine the order of tests based on test name instead of test
+case name, then we would have a problem with the following situation:
+
+```c++
+TEST_F(FooTest, AbcDeathTest) { ... }
+TEST_F(FooTest, Uvw) { ... }
+
+TEST_F(BarTest, DefDeathTest) { ... }
+TEST_F(BarTest, Xyz) { ... }
+```
+
+Since `FooTest.AbcDeathTest` needs to run before `BarTest.Xyz`, and we don't
+interleave tests from different test suites, we need to run all tests in the
+`FooTest` case before running any test in the `BarTest` case. This contradicts
+with the requirement to run `BarTest.DefDeathTest` before `FooTest.Uvw`.
+
+## But I don't like calling my entire test suite \*DeathTest when it contains both death tests and non-death tests. What do I do?
+
+You don't have to, but if you like, you may split up the test suite into
+`FooTest` and `FooDeathTest`, where the names make it clear that they are
+related:
+
+```c++
+class FooTest : public ::testing::Test { ... };
+
+TEST_F(FooTest, Abc) { ... }
+TEST_F(FooTest, Def) { ... }
+
+using FooDeathTest = FooTest;
+
+TEST_F(FooDeathTest, Uvw) { ... EXPECT_DEATH(...) ... }
+TEST_F(FooDeathTest, Xyz) { ... ASSERT_DEATH(...) ... }
+```
+
+## googletest prints the LOG messages in a death test's child process only when the test fails. How can I see the LOG messages when the death test succeeds?
+
+Printing the LOG messages generated by the statement inside `EXPECT_DEATH()`
+makes it harder to search for real problems in the parent's log. Therefore,
+googletest only prints them when the death test has failed.
+
+If you really need to see such LOG messages, a workaround is to temporarily
+break the death test (e.g. by changing the regex pattern it is expected to
+match). Admittedly, this is a hack. We'll consider a more permanent solution
+after the fork-and-exec-style death tests are implemented.
+
+## The compiler complains about `no match for 'operator<<'` when I use an assertion. What gives?
+
+If you use a user-defined type `FooType` in an assertion, you must make sure
+there is an `std::ostream& operator<<(std::ostream&, const FooType&)` function
+defined such that we can print a value of `FooType`.
+
+In addition, if `FooType` is declared in a name space, the `<<` operator also
+needs to be defined in the *same* name space. See
+[Tip of the Week #49](http://abseil.io/tips/49) for details.
+
+## How do I suppress the memory leak messages on Windows?
+
+Since the statically initialized googletest singleton requires allocations on
+the heap, the Visual C++ memory leak detector will report memory leaks at the
+end of the program run. The easiest way to avoid this is to use the
+`_CrtMemCheckpoint` and `_CrtMemDumpAllObjectsSince` calls to not report any
+statically initialized heap objects. See MSDN for more details and additional
+heap check/debug routines.
+
+## How can my code detect if it is running in a test?
+
+If you write code that sniffs whether it's running in a test and does different
+things accordingly, you are leaking test-only logic into production code and
+there is no easy way to ensure that the test-only code paths aren't run by
+mistake in production. Such cleverness also leads to
+[Heisenbugs](https://en.wikipedia.org/wiki/Heisenbug). Therefore we strongly
+advise against the practice, and googletest doesn't provide a way to do it.
+
+In general, the recommended way to cause the code to behave differently under
+test is [Dependency Injection](http://en.wikipedia.org/wiki/Dependency_injection). You can inject
+different functionality from the test and from the production code. Since your
+production code doesn't link in the for-test logic at all (the
+[`testonly`](http://docs.bazel.build/versions/master/be/common-definitions.html#common.testonly) attribute for BUILD targets helps to ensure
+that), there is no danger in accidentally running it.
+
+However, if you *really*, *really*, *really* have no choice, and if you follow
+the rule of ending your test program names with `_test`, you can use the
+*horrible* hack of sniffing your executable name (`argv[0]` in `main()`) to know
+whether the code is under test.
+
+## How do I temporarily disable a test?
+
+If you have a broken test that you cannot fix right away, you can add the
+`DISABLED_` prefix to its name. This will exclude it from execution. This is
+better than commenting out the code or using `#if 0`, as disabled tests are
+still compiled (and thus won't rot).
+
+To include disabled tests in test execution, just invoke the test program with
+the `--gtest_also_run_disabled_tests` flag.
+
+## Is it OK if I have two separate `TEST(Foo, Bar)` test methods defined in different namespaces?
+
+Yes.
+
+The rule is **all test methods in the same test suite must use the same fixture
+class.** This means that the following is **allowed** because both tests use the
+same fixture class (`::testing::Test`).
+
+```c++
+namespace foo {
+TEST(CoolTest, DoSomething) {
+ SUCCEED();
+}
+} // namespace foo
+
+namespace bar {
+TEST(CoolTest, DoSomething) {
+ SUCCEED();
+}
+} // namespace bar
+```
+
+However, the following code is **not allowed** and will produce a runtime error
+from googletest because the test methods are using different test fixture
+classes with the same test suite name.
+
+```c++
+namespace foo {
+class CoolTest : public ::testing::Test {}; // Fixture foo::CoolTest
+TEST_F(CoolTest, DoSomething) {
+ SUCCEED();
+}
+} // namespace foo
+
+namespace bar {
+class CoolTest : public ::testing::Test {}; // Fixture: bar::CoolTest
+TEST_F(CoolTest, DoSomething) {
+ SUCCEED();
+}
+} // namespace bar
+```

+# gMock Cheat Sheet
+
+## Defining a Mock Class
+
+### Mocking a Normal Class {#MockClass}
+
+Given
+
+```cpp
+class Foo {
+ ...
+ virtual ~Foo();
+ virtual int GetSize() const = 0;
+ virtual string Describe(const char* name) = 0;
+ virtual string Describe(int type) = 0;
+ virtual bool Process(Bar elem, int count) = 0;
+};
+```
+
+(note that `~Foo()` **must** be virtual) we can define its mock as
+
+```cpp
+#include "gmock/gmock.h"
+
+class MockFoo : public Foo {
+ ...
+ MOCK_METHOD(int, GetSize, (), (const, override));
+ MOCK_METHOD(string, Describe, (const char* name), (override));
+ MOCK_METHOD(string, Describe, (int type), (override));
+ MOCK_METHOD(bool, Process, (Bar elem, int count), (override));
+};
+```
+
+To create a "nice" mock, which ignores all uninteresting calls, a "naggy" mock,
+which warns on all uninteresting calls, or a "strict" mock, which treats them as
+failures:
+
+```cpp
+using ::testing::NiceMock;
+using ::testing::NaggyMock;
+using ::testing::StrictMock;
+
+NiceMock<MockFoo> nice_foo; // The type is a subclass of MockFoo.
+NaggyMock<MockFoo> naggy_foo; // The type is a subclass of MockFoo.
+StrictMock<MockFoo> strict_foo; // The type is a subclass of MockFoo.
+```
+
+{: .callout .note}
+**Note:** A mock object is currently naggy by default. We may make it nice by
+default in the future.
+
+### Mocking a Class Template {#MockTemplate}
+
+Class templates can be mocked just like any class.
+
+To mock
+
+```cpp
+template <typename Elem>
+class StackInterface {
+ ...
+ virtual ~StackInterface();
+ virtual int GetSize() const = 0;
+ virtual void Push(const Elem& x) = 0;
+};
+```
+
+(note that all member functions that are mocked, including `~StackInterface()`
+**must** be virtual).
+
+```cpp
+template <typename Elem>
+class MockStack : public StackInterface<Elem> {
+ ...
+ MOCK_METHOD(int, GetSize, (), (const, override));
+ MOCK_METHOD(void, Push, (const Elem& x), (override));
+};
+```
+
+### Specifying Calling Conventions for Mock Functions
+
+If your mock function doesn't use the default calling convention, you can
+specify it by adding `Calltype(convention)` to `MOCK_METHOD`'s 4th parameter.
+For example,
+
+```cpp
+ MOCK_METHOD(bool, Foo, (int n), (Calltype(STDMETHODCALLTYPE)));
+ MOCK_METHOD(int, Bar, (double x, double y),
+ (const, Calltype(STDMETHODCALLTYPE)));
+```
+
+where `STDMETHODCALLTYPE` is defined by `<objbase.h>` on Windows.
+
+## Using Mocks in Tests {#UsingMocks}
+
+The typical work flow is:
+
+1. Import the gMock names you need to use. All gMock symbols are in the
+ `testing` namespace unless they are macros or otherwise noted.
+2. Create the mock objects.
+3. Optionally, set the default actions of the mock objects.
+4. Set your expectations on the mock objects (How will they be called? What
+ will they do?).
+5. Exercise code that uses the mock objects; if necessary, check the result
+ using googletest assertions.
+6. When a mock object is destructed, gMock automatically verifies that all
+ expectations on it have been satisfied.
+
+Here's an example:
+
+```cpp
+using ::testing::Return; // #1
+
+TEST(BarTest, DoesThis) {
+ MockFoo foo; // #2
+
+ ON_CALL(foo, GetSize()) // #3
+ .WillByDefault(Return(1));
+ // ... other default actions ...
+
+ EXPECT_CALL(foo, Describe(5)) // #4
+ .Times(3)
+ .WillRepeatedly(Return("Category 5"));
+ // ... other expectations ...
+
+ EXPECT_EQ(MyProductionFunction(&foo), "good"); // #5
+} // #6
+```
+
+## Setting Default Actions {#OnCall}
+
+gMock has a **built-in default action** for any function that returns `void`,
+`bool`, a numeric value, or a pointer. In C++11, it will additionally returns
+the default-constructed value, if one exists for the given type.
+
+To customize the default action for functions with return type `T`, use
+[`DefaultValue<T>`](reference/mocking.md#DefaultValue). For example:
+
+```cpp
+ // Sets the default action for return type std::unique_ptr<Buzz> to
+ // creating a new Buzz every time.
+ DefaultValue<std::unique_ptr<Buzz>>::SetFactory(
+ [] { return MakeUnique<Buzz>(AccessLevel::kInternal); });
+
+ // When this fires, the default action of MakeBuzz() will run, which
+ // will return a new Buzz object.
+ EXPECT_CALL(mock_buzzer_, MakeBuzz("hello")).Times(AnyNumber());
+
+ auto buzz1 = mock_buzzer_.MakeBuzz("hello");
+ auto buzz2 = mock_buzzer_.MakeBuzz("hello");
+ EXPECT_NE(buzz1, nullptr);
+ EXPECT_NE(buzz2, nullptr);
+ EXPECT_NE(buzz1, buzz2);
+
+ // Resets the default action for return type std::unique_ptr<Buzz>,
+ // to avoid interfere with other tests.
+ DefaultValue<std::unique_ptr<Buzz>>::Clear();
+```
+
+To customize the default action for a particular method of a specific mock
+object, use [`ON_CALL`](reference/mocking.md#ON_CALL). `ON_CALL` has a similar
+syntax to `EXPECT_CALL`, but it is used for setting default behaviors when you
+do not require that the mock method is called. See
+[Knowing When to Expect](gmock_cook_book.md#UseOnCall) for a more detailed
+discussion.
+
+## Setting Expectations {#ExpectCall}
+
+See [`EXPECT_CALL`](reference/mocking.md#EXPECT_CALL) in the Mocking Reference.
+
+## Matchers {#MatcherList}
+
+See the [Matchers Reference](reference/matchers.md).
+
+## Actions {#ActionList}
+
+See the [Actions Reference](reference/actions.md).
+
+## Cardinalities {#CardinalityList}
+
+See the [`Times` clause](reference/mocking.md#EXPECT_CALL.Times) of
+`EXPECT_CALL` in the Mocking Reference.
+
+## Expectation Order
+
+By default, expectations can be matched in *any* order. If some or all
+expectations must be matched in a given order, you can use the
+[`After` clause](reference/mocking.md#EXPECT_CALL.After) or
+[`InSequence` clause](reference/mocking.md#EXPECT_CALL.InSequence) of
+`EXPECT_CALL`, or use an [`InSequence` object](reference/mocking.md#InSequence).
+
+## Verifying and Resetting a Mock
+
+gMock will verify the expectations on a mock object when it is destructed, or
+you can do it earlier:
+
+```cpp
+using ::testing::Mock;
+...
+// Verifies and removes the expectations on mock_obj;
+// returns true if and only if successful.
+Mock::VerifyAndClearExpectations(&mock_obj);
+...
+// Verifies and removes the expectations on mock_obj;
+// also removes the default actions set by ON_CALL();
+// returns true if and only if successful.
+Mock::VerifyAndClear(&mock_obj);
+```
+
+Do not set new expectations after verifying and clearing a mock after its use.
+Setting expectations after code that exercises the mock has undefined behavior.
+See [Using Mocks in Tests](gmock_for_dummies.md#using-mocks-in-tests) for more
+information.
+
+You can also tell gMock that a mock object can be leaked and doesn't need to be
+verified:
+
+```cpp
+Mock::AllowLeak(&mock_obj);
+```
+
+## Mock Classes
+
+gMock defines a convenient mock class template
+
+```cpp
+class MockFunction<R(A1, ..., An)> {
+ public:
+ MOCK_METHOD(R, Call, (A1, ..., An));
+};
+```
+
+See this [recipe](gmock_cook_book.md#UsingCheckPoints) for one application of
+it.
+
+## Flags
+
+| Flag | Description |
+| :----------------------------- | :---------------------------------------- |
+| `--gmock_catch_leaked_mocks=0` | Don't report leaked mock objects as failures. |
+| `--gmock_verbose=LEVEL` | Sets the default verbosity level (`info`, `warning`, or `error`) of Google Mock messages. |

+# gMock Cookbook
+
+You can find recipes for using gMock here. If you haven't yet, please read
+[the dummy guide](gmock_for_dummies.md) first to make sure you understand the
+basics.
+
+{: .callout .note}
+**Note:** gMock lives in the `testing` name space. For readability, it is
+recommended to write `using ::testing::Foo;` once in your file before using the
+name `Foo` defined by gMock. We omit such `using` statements in this section for
+brevity, but you should do it in your own code.
+
+## Creating Mock Classes
+
+Mock classes are defined as normal classes, using the `MOCK_METHOD` macro to
+generate mocked methods. The macro gets 3 or 4 parameters:
+
+```cpp
+class MyMock {
+ public:
+ MOCK_METHOD(ReturnType, MethodName, (Args...));
+ MOCK_METHOD(ReturnType, MethodName, (Args...), (Specs...));
+};
+```
+
+The first 3 parameters are simply the method declaration, split into 3 parts.
+The 4th parameter accepts a closed list of qualifiers, which affect the
+generated method:
+
+* **`const`** - Makes the mocked method a `const` method. Required if
+ overriding a `const` method.
+* **`override`** - Marks the method with `override`. Recommended if overriding
+ a `virtual` method.
+* **`noexcept`** - Marks the method with `noexcept`. Required if overriding a
+ `noexcept` method.
+* **`Calltype(...)`** - Sets the call type for the method (e.g. to
+ `STDMETHODCALLTYPE`), useful in Windows.
+* **`ref(...)`** - Marks the method with the reference qualification
+ specified. Required if overriding a method that has reference
+ qualifications. Eg `ref(&)` or `ref(&&)`.
+
+### Dealing with unprotected commas
+
+Unprotected commas, i.e. commas which are not surrounded by parentheses, prevent
+`MOCK_METHOD` from parsing its arguments correctly:
+
+{: .bad}
+```cpp
+class MockFoo {
+ public:
+ MOCK_METHOD(std::pair<bool, int>, GetPair, ()); // Won't compile!
+ MOCK_METHOD(bool, CheckMap, (std::map<int, double>, bool)); // Won't compile!
+};
+```
+
+Solution 1 - wrap with parentheses:
+
+{: .good}
+```cpp
+class MockFoo {
+ public:
+ MOCK_METHOD((std::pair<bool, int>), GetPair, ());
+ MOCK_METHOD(bool, CheckMap, ((std::map<int, double>), bool));
+};
+```
+
+Note that wrapping a return or argument type with parentheses is, in general,
+invalid C++. `MOCK_METHOD` removes the parentheses.
+
+Solution 2 - define an alias:
+
+{: .good}
+```cpp
+class MockFoo {
+ public:
+ using BoolAndInt = std::pair<bool, int>;
+ MOCK_METHOD(BoolAndInt, GetPair, ());
+ using MapIntDouble = std::map<int, double>;
+ MOCK_METHOD(bool, CheckMap, (MapIntDouble, bool));
+};
+```
+
+### Mocking Private or Protected Methods
+
+You must always put a mock method definition (`MOCK_METHOD`) in a `public:`
+section of the mock class, regardless of the method being mocked being `public`,
+`protected`, or `private` in the base class. This allows `ON_CALL` and
+`EXPECT_CALL` to reference the mock function from outside of the mock class.
+(Yes, C++ allows a subclass to change the access level of a virtual function in
+the base class.) Example:
+
+```cpp
+class Foo {
+ public:
+ ...
+ virtual bool Transform(Gadget* g) = 0;
+
+ protected:
+ virtual void Resume();
+
+ private:
+ virtual int GetTimeOut();
+};
+
+class MockFoo : public Foo {
+ public:
+ ...
+ MOCK_METHOD(bool, Transform, (Gadget* g), (override));
+
+ // The following must be in the public section, even though the
+ // methods are protected or private in the base class.
+ MOCK_METHOD(void, Resume, (), (override));
+ MOCK_METHOD(int, GetTimeOut, (), (override));
+};
+```
+
+### Mocking Overloaded Methods
+
+You can mock overloaded functions as usual. No special attention is required:
+
+```cpp
+class Foo {
+ ...
+
+ // Must be virtual as we'll inherit from Foo.
+ virtual ~Foo();
+
+ // Overloaded on the types and/or numbers of arguments.
+ virtual int Add(Element x);
+ virtual int Add(int times, Element x);
+
+ // Overloaded on the const-ness of this object.
+ virtual Bar& GetBar();
+ virtual const Bar& GetBar() const;
+};
+
+class MockFoo : public Foo {
+ ...
+ MOCK_METHOD(int, Add, (Element x), (override));
+ MOCK_METHOD(int, Add, (int times, Element x), (override));
+
+ MOCK_METHOD(Bar&, GetBar, (), (override));
+ MOCK_METHOD(const Bar&, GetBar, (), (const, override));
+};
+```
+
+{: .callout .note}
+**Note:** if you don't mock all versions of the overloaded method, the compiler
+will give you a warning about some methods in the base class being hidden. To
+fix that, use `using` to bring them in scope:
+
+```cpp
+class MockFoo : public Foo {
+ ...
+ using Foo::Add;
+ MOCK_METHOD(int, Add, (Element x), (override));
+ // We don't want to mock int Add(int times, Element x);
+ ...
+};
+```
+
+### Mocking Class Templates
+
+You can mock class templates just like any class.
+
+```cpp
+template <typename Elem>
+class StackInterface {
+ ...
+ // Must be virtual as we'll inherit from StackInterface.
+ virtual ~StackInterface();
+
+ virtual int GetSize() const = 0;
+ virtual void Push(const Elem& x) = 0;
+};
+
+template <typename Elem>
+class MockStack : public StackInterface<Elem> {
+ ...
+ MOCK_METHOD(int, GetSize, (), (override));
+ MOCK_METHOD(void, Push, (const Elem& x), (override));
+};
+```
+
+### Mocking Non-virtual Methods {#MockingNonVirtualMethods}
+
+gMock can mock non-virtual functions to be used in Hi-perf dependency injection.
+
+In this case, instead of sharing a common base class with the real class, your
+mock class will be *unrelated* to the real class, but contain methods with the
+same signatures. The syntax for mocking non-virtual methods is the *same* as
+mocking virtual methods (just don't add `override`):
+
+```cpp
+// A simple packet stream class. None of its members is virtual.
+class ConcretePacketStream {
+ public:
+ void AppendPacket(Packet* new_packet);
+ const Packet* GetPacket(size_t packet_number) const;
+ size_t NumberOfPackets() const;
+ ...
+};
+
+// A mock packet stream class. It inherits from no other, but defines
+// GetPacket() and NumberOfPackets().
+class MockPacketStream {
+ public:
+ MOCK_METHOD(const Packet*, GetPacket, (size_t packet_number), (const));
+ MOCK_METHOD(size_t, NumberOfPackets, (), (const));
+ ...
+};
+```
+
+Note that the mock class doesn't define `AppendPacket()`, unlike the real class.
+That's fine as long as the test doesn't need to call it.
+
+Next, you need a way to say that you want to use `ConcretePacketStream` in
+production code, and use `MockPacketStream` in tests. Since the functions are
+not virtual and the two classes are unrelated, you must specify your choice at
+*compile time* (as opposed to run time).
+
+One way to do it is to templatize your code that needs to use a packet stream.
+More specifically, you will give your code a template type argument for the type
+of the packet stream. In production, you will instantiate your template with
+`ConcretePacketStream` as the type argument. In tests, you will instantiate the
+same template with `MockPacketStream`. For example, you may write:
+
+```cpp
+template <class PacketStream>
+void CreateConnection(PacketStream* stream) { ... }
+
+template <class PacketStream>
+class PacketReader {
+ public:
+ void ReadPackets(PacketStream* stream, size_t packet_num);
+};
+```
+
+Then you can use `CreateConnection<ConcretePacketStream>()` and
+`PacketReader<ConcretePacketStream>` in production code, and use
+`CreateConnection<MockPacketStream>()` and `PacketReader<MockPacketStream>` in
+tests.
+
+```cpp
+ MockPacketStream mock_stream;
+ EXPECT_CALL(mock_stream, ...)...;
+ .. set more expectations on mock_stream ...
+ PacketReader<MockPacketStream> reader(&mock_stream);
+ ... exercise reader ...
+```
+
+### Mocking Free Functions
+
+It is not possible to directly mock a free function (i.e. a C-style function or
+a static method). If you need to, you can rewrite your code to use an interface
+(abstract class).
+
+Instead of calling a free function (say, `OpenFile`) directly, introduce an
+interface for it and have a concrete subclass that calls the free function:
+
+```cpp
+class FileInterface {
+ public:
+ ...
+ virtual bool Open(const char* path, const char* mode) = 0;
+};
+
+class File : public FileInterface {
+ public:
+ ...
+ bool Open(const char* path, const char* mode) override {
+ return OpenFile(path, mode);
+ }
+};
+```
+
+Your code should talk to `FileInterface` to open a file. Now it's easy to mock
+out the function.
+
+This may seem like a lot of hassle, but in practice you often have multiple
+related functions that you can put in the same interface, so the per-function
+syntactic overhead will be much lower.
+
+If you are concerned about the performance overhead incurred by virtual
+functions, and profiling confirms your concern, you can combine this with the
+recipe for [mocking non-virtual methods](#MockingNonVirtualMethods).
+
+### Old-Style `MOCK_METHODn` Macros
+
+Before the generic `MOCK_METHOD` macro
+[was introduced in 2018](https://github.com/google/googletest/commit/c5f08bf91944ce1b19bcf414fa1760e69d20afc2),
+mocks where created using a family of macros collectively called `MOCK_METHODn`.
+These macros are still supported, though migration to the new `MOCK_METHOD` is
+recommended.
+
+The macros in the `MOCK_METHODn` family differ from `MOCK_METHOD`:
+
+* The general structure is `MOCK_METHODn(MethodName, ReturnType(Args))`,
+ instead of `MOCK_METHOD(ReturnType, MethodName, (Args))`.
+* The number `n` must equal the number of arguments.
+* When mocking a const method, one must use `MOCK_CONST_METHODn`.
+* When mocking a class template, the macro name must be suffixed with `_T`.
+* In order to specify the call type, the macro name must be suffixed with
+ `_WITH_CALLTYPE`, and the call type is the first macro argument.
+
+Old macros and their new equivalents:

+
+### The Nice, the Strict, and the Naggy {#NiceStrictNaggy}
+
+If a mock method has no `EXPECT_CALL` spec but is called, we say that it's an
+"uninteresting call", and the default action (which can be specified using
+`ON_CALL()`) of the method will be taken. Currently, an uninteresting call will
+also by default cause gMock to print a warning. (In the future, we might remove
+this warning by default.)
+
+However, sometimes you may want to ignore these uninteresting calls, and
+sometimes you may want to treat them as errors. gMock lets you make the decision
+on a per-mock-object basis.
+
+Suppose your test uses a mock class `MockFoo`:
+
+```cpp
+TEST(...) {
+ MockFoo mock_foo;
+ EXPECT_CALL(mock_foo, DoThis());
+ ... code that uses mock_foo ...
+}
+```
+
+If a method of `mock_foo` other than `DoThis()` is called, you will get a
+warning. However, if you rewrite your test to use `NiceMock<MockFoo>` instead,
+you can suppress the warning:
+
+```cpp
+using ::testing::NiceMock;
+
+TEST(...) {
+ NiceMock<MockFoo> mock_foo;
+ EXPECT_CALL(mock_foo, DoThis());
+ ... code that uses mock_foo ...
+}
+```
+
+`NiceMock<MockFoo>` is a subclass of `MockFoo`, so it can be used wherever
+`MockFoo` is accepted.
+
+It also works if `MockFoo`'s constructor takes some arguments, as
+`NiceMock<MockFoo>` "inherits" `MockFoo`'s constructors:
+
+```cpp
+using ::testing::NiceMock;
+
+TEST(...) {
+ NiceMock<MockFoo> mock_foo(5, "hi"); // Calls MockFoo(5, "hi").
+ EXPECT_CALL(mock_foo, DoThis());
+ ... code that uses mock_foo ...
+}
+```
+
+The usage of `StrictMock` is similar, except that it makes all uninteresting
+calls failures:
+
+```cpp
+using ::testing::StrictMock;
+
+TEST(...) {
+ StrictMock<MockFoo> mock_foo;
+ EXPECT_CALL(mock_foo, DoThis());
+ ... code that uses mock_foo ...
+
+ // The test will fail if a method of mock_foo other than DoThis()
+ // is called.
+}
+```
+
+{: .callout .note}
+NOTE: `NiceMock` and `StrictMock` only affects *uninteresting* calls (calls of
+*methods* with no expectations); they do not affect *unexpected* calls (calls of
+methods with expectations, but they don't match). See
+[Understanding Uninteresting vs Unexpected Calls](#uninteresting-vs-unexpected).
+
+There are some caveats though (sadly they are side effects of C++'s
+limitations):
+
+1. `NiceMock<MockFoo>` and `StrictMock<MockFoo>` only work for mock methods
+ defined using the `MOCK_METHOD` macro **directly** in the `MockFoo` class.
+ If a mock method is defined in a **base class** of `MockFoo`, the "nice" or
+ "strict" modifier may not affect it, depending on the compiler. In
+ particular, nesting `NiceMock` and `StrictMock` (e.g.
+ `NiceMock<StrictMock<MockFoo> >`) is **not** supported.
+2. `NiceMock<MockFoo>` and `StrictMock<MockFoo>` may not work correctly if the
+ destructor of `MockFoo` is not virtual. We would like to fix this, but it
+ requires cleaning up existing tests.
+
+Finally, you should be **very cautious** about when to use naggy or strict
+mocks, as they tend to make tests more brittle and harder to maintain. When you
+refactor your code without changing its externally visible behavior, ideally you
+shouldn't need to update any tests. If your code interacts with a naggy mock,
+however, you may start to get spammed with warnings as the result of your
+change. Worse, if your code interacts with a strict mock, your tests may start
+to fail and you'll be forced to fix them. Our general recommendation is to use
+nice mocks (not yet the default) most of the time, use naggy mocks (the current
+default) when developing or debugging tests, and use strict mocks only as the
+last resort.
+
+### Simplifying the Interface without Breaking Existing Code {#SimplerInterfaces}
+
+Sometimes a method has a long list of arguments that is mostly uninteresting.
+For example:
+
+```cpp
+class LogSink {
+ public:
+ ...
+ virtual void send(LogSeverity severity, const char* full_filename,
+ const char* base_filename, int line,
+ const struct tm* tm_time,
+ const char* message, size_t message_len) = 0;
+};
+```
+
+This method's argument list is lengthy and hard to work with (the `message`
+argument is not even 0-terminated). If we mock it as is, using the mock will be
+awkward. If, however, we try to simplify this interface, we'll need to fix all
+clients depending on it, which is often infeasible.
+
+The trick is to redispatch the method in the mock class:
+
+```cpp
+class ScopedMockLog : public LogSink {
+ public:
+ ...
+ void send(LogSeverity severity, const char* full_filename,
+ const char* base_filename, int line, const tm* tm_time,
+ const char* message, size_t message_len) override {
+ // We are only interested in the log severity, full file name, and
+ // log message.
+ Log(severity, full_filename, std::string(message, message_len));
+ }
+
+ // Implements the mock method:
+ //
+ // void Log(LogSeverity severity,
+ // const string& file_path,
+ // const string& message);
+ MOCK_METHOD(void, Log,
+ (LogSeverity severity, const string& file_path,
+ const string& message));
+};
+```
+
+By defining a new mock method with a trimmed argument list, we make the mock
+class more user-friendly.
+
+This technique may also be applied to make overloaded methods more amenable to
+mocking. For example, when overloads have been used to implement default
+arguments:
+
+```cpp
+class MockTurtleFactory : public TurtleFactory {
+ public:
+ Turtle* MakeTurtle(int length, int weight) override { ... }
+ Turtle* MakeTurtle(int length, int weight, int speed) override { ... }
+
+ // the above methods delegate to this one:
+ MOCK_METHOD(Turtle*, DoMakeTurtle, ());
+};
+```
+
+This allows tests that don't care which overload was invoked to avoid specifying
+argument matchers:
+
+```cpp
+ON_CALL(factory, DoMakeTurtle)
+ .WillByDefault(Return(MakeMockTurtle()));
+```
+
+### Alternative to Mocking Concrete Classes
+
+Often you may find yourself using classes that don't implement interfaces. In
+order to test your code that uses such a class (let's call it `Concrete`), you
+may be tempted to make the methods of `Concrete` virtual and then mock it.
+
+Try not to do that.
+
+Making a non-virtual function virtual is a big decision. It creates an extension
+point where subclasses can tweak your class' behavior. This weakens your control
+on the class because now it's harder to maintain the class invariants. You
+should make a function virtual only when there is a valid reason for a subclass
+to override it.
+
+Mocking concrete classes directly is problematic as it creates a tight coupling
+between the class and the tests - any small change in the class may invalidate
+your tests and make test maintenance a pain.
+
+To avoid such problems, many programmers have been practicing "coding to
+interfaces": instead of talking to the `Concrete` class, your code would define
+an interface and talk to it. Then you implement that interface as an adaptor on
+top of `Concrete`. In tests, you can easily mock that interface to observe how
+your code is doing.
+
+This technique incurs some overhead:
+
+* You pay the cost of virtual function calls (usually not a problem).
+* There is more abstraction for the programmers to learn.
+
+However, it can also bring significant benefits in addition to better
+testability:
+
+* `Concrete`'s API may not fit your problem domain very well, as you may not
+ be the only client it tries to serve. By designing your own interface, you
+ have a chance to tailor it to your need - you may add higher-level
+ functionalities, rename stuff, etc instead of just trimming the class. This
+ allows you to write your code (user of the interface) in a more natural way,
+ which means it will be more readable, more maintainable, and you'll be more
+ productive.
+* If `Concrete`'s implementation ever has to change, you don't have to rewrite
+ everywhere it is used. Instead, you can absorb the change in your
+ implementation of the interface, and your other code and tests will be
+ insulated from this change.
+
+Some people worry that if everyone is practicing this technique, they will end
+up writing lots of redundant code. This concern is totally understandable.
+However, there are two reasons why it may not be the case:
+
+* Different projects may need to use `Concrete` in different ways, so the best
+ interfaces for them will be different. Therefore, each of them will have its
+ own domain-specific interface on top of `Concrete`, and they will not be the
+ same code.
+* If enough projects want to use the same interface, they can always share it,
+ just like they have been sharing `Concrete`. You can check in the interface
+ and the adaptor somewhere near `Concrete` (perhaps in a `contrib`
+ sub-directory) and let many projects use it.
+
+You need to weigh the pros and cons carefully for your particular problem, but
+I'd like to assure you that the Java community has been practicing this for a
+long time and it's a proven effective technique applicable in a wide variety of
+situations. :-)
+
+### Delegating Calls to a Fake {#DelegatingToFake}
+
+Some times you have a non-trivial fake implementation of an interface. For
+example:
+
+```cpp
+class Foo {
+ public:
+ virtual ~Foo() {}
+ virtual char DoThis(int n) = 0;
+ virtual void DoThat(const char* s, int* p) = 0;
+};
+
+class FakeFoo : public Foo {
+ public:
+ char DoThis(int n) override {
+ return (n > 0) ? '+' :
+ (n < 0) ? '-' : '0';
+ }
+
+ void DoThat(const char* s, int* p) override {
+ *p = strlen(s);
+ }
+};
+```
+
+Now you want to mock this interface such that you can set expectations on it.
+However, you also want to use `FakeFoo` for the default behavior, as duplicating
+it in the mock object is, well, a lot of work.
+
+When you define the mock class using gMock, you can have it delegate its default
+action to a fake class you already have, using this pattern:
+
+```cpp
+class MockFoo : public Foo {
+ public:
+ // Normal mock method definitions using gMock.
+ MOCK_METHOD(char, DoThis, (int n), (override));
+ MOCK_METHOD(void, DoThat, (const char* s, int* p), (override));
+
+ // Delegates the default actions of the methods to a FakeFoo object.
+ // This must be called *before* the custom ON_CALL() statements.
+ void DelegateToFake() {
+ ON_CALL(*this, DoThis).WillByDefault([this](int n) {
+ return fake_.DoThis(n);
+ });
+ ON_CALL(*this, DoThat).WillByDefault([this](const char* s, int* p) {
+ fake_.DoThat(s, p);
+ });
+ }
+
+ private:
+ FakeFoo fake_; // Keeps an instance of the fake in the mock.
+};
+```
+
+With that, you can use `MockFoo` in your tests as usual. Just remember that if
+you don't explicitly set an action in an `ON_CALL()` or `EXPECT_CALL()`, the
+fake will be called upon to do it.:
+
+```cpp
+using ::testing::_;
+
+TEST(AbcTest, Xyz) {
+ MockFoo foo;
+
+ foo.DelegateToFake(); // Enables the fake for delegation.
+
+ // Put your ON_CALL(foo, ...)s here, if any.
+
+ // No action specified, meaning to use the default action.
+ EXPECT_CALL(foo, DoThis(5));
+ EXPECT_CALL(foo, DoThat(_, _));
+
+ int n = 0;
+ EXPECT_EQ('+', foo.DoThis(5)); // FakeFoo::DoThis() is invoked.
+ foo.DoThat("Hi", &n); // FakeFoo::DoThat() is invoked.
+ EXPECT_EQ(2, n);
+}
+```
+
+**Some tips:**
+
+* If you want, you can still override the default action by providing your own
+ `ON_CALL()` or using `.WillOnce()` / `.WillRepeatedly()` in `EXPECT_CALL()`.
+* In `DelegateToFake()`, you only need to delegate the methods whose fake
+ implementation you intend to use.
+
+* The general technique discussed here works for overloaded methods, but
+ you'll need to tell the compiler which version you mean. To disambiguate a
+ mock function (the one you specify inside the parentheses of `ON_CALL()`),
+ use [this technique](#SelectOverload); to disambiguate a fake function (the
+ one you place inside `Invoke()`), use a `static_cast` to specify the
+ function's type. For instance, if class `Foo` has methods `char DoThis(int
+ n)` and `bool DoThis(double x) const`, and you want to invoke the latter,
+ you need to write `Invoke(&fake_, static_cast<bool (FakeFoo::*)(double)
+ const>(&FakeFoo::DoThis))` instead of `Invoke(&fake_, &FakeFoo::DoThis)`
+ (The strange-looking thing inside the angled brackets of `static_cast` is
+ the type of a function pointer to the second `DoThis()` method.).
+
+* Having to mix a mock and a fake is often a sign of something gone wrong.
+ Perhaps you haven't got used to the interaction-based way of testing yet. Or
+ perhaps your interface is taking on too many roles and should be split up.
+ Therefore, **don't abuse this**. We would only recommend to do it as an
+ intermediate step when you are refactoring your code.
+
+Regarding the tip on mixing a mock and a fake, here's an example on why it may
+be a bad sign: Suppose you have a class `System` for low-level system
+operations. In particular, it does file and I/O operations. And suppose you want
+to test how your code uses `System` to do I/O, and you just want the file
+operations to work normally. If you mock out the entire `System` class, you'll
+have to provide a fake implementation for the file operation part, which
+suggests that `System` is taking on too many roles.
+
+Instead, you can define a `FileOps` interface and an `IOOps` interface and split
+`System`'s functionalities into the two. Then you can mock `IOOps` without
+mocking `FileOps`.
+
+### Delegating Calls to a Real Object
+
+When using testing doubles (mocks, fakes, stubs, and etc), sometimes their
+behaviors will differ from those of the real objects. This difference could be
+either intentional (as in simulating an error such that you can test the error
+handling code) or unintentional. If your mocks have different behaviors than the
+real objects by mistake, you could end up with code that passes the tests but
+fails in production.
+
+You can use the *delegating-to-real* technique to ensure that your mock has the
+same behavior as the real object while retaining the ability to validate calls.
+This technique is very similar to the [delegating-to-fake](#DelegatingToFake)
+technique, the difference being that we use a real object instead of a fake.
+Here's an example:
+
+```cpp
+using ::testing::AtLeast;
+
+class MockFoo : public Foo {
+ public:
+ MockFoo() {
+ // By default, all calls are delegated to the real object.
+ ON_CALL(*this, DoThis).WillByDefault([this](int n) {
+ return real_.DoThis(n);
+ });
+ ON_CALL(*this, DoThat).WillByDefault([this](const char* s, int* p) {
+ real_.DoThat(s, p);
+ });
+ ...
+ }
+ MOCK_METHOD(char, DoThis, ...);
+ MOCK_METHOD(void, DoThat, ...);
+ ...
+ private:
+ Foo real_;
+};
+
+...
+ MockFoo mock;
+ EXPECT_CALL(mock, DoThis())
+ .Times(3);
+ EXPECT_CALL(mock, DoThat("Hi"))
+ .Times(AtLeast(1));
+ ... use mock in test ...
+```
+
+With this, gMock will verify that your code made the right calls (with the right
+arguments, in the right order, called the right number of times, etc), and a
+real object will answer the calls (so the behavior will be the same as in
+production). This gives you the best of both worlds.
+
+### Delegating Calls to a Parent Class
+
+Ideally, you should code to interfaces, whose methods are all pure virtual. In
+reality, sometimes you do need to mock a virtual method that is not pure (i.e,
+it already has an implementation). For example:
+
+```cpp
+class Foo {
+ public:
+ virtual ~Foo();
+
+ virtual void Pure(int n) = 0;
+ virtual int Concrete(const char* str) { ... }
+};
+
+class MockFoo : public Foo {
+ public:
+ // Mocking a pure method.
+ MOCK_METHOD(void, Pure, (int n), (override));
+ // Mocking a concrete method. Foo::Concrete() is shadowed.
+ MOCK_METHOD(int, Concrete, (const char* str), (override));
+};
+```
+
+Sometimes you may want to call `Foo::Concrete()` instead of
+`MockFoo::Concrete()`. Perhaps you want to do it as part of a stub action, or
+perhaps your test doesn't need to mock `Concrete()` at all (but it would be
+oh-so painful to have to define a new mock class whenever you don't need to mock
+one of its methods).
+
+You can call `Foo::Concrete()` inside an action by:
+
+```cpp
+...
+ EXPECT_CALL(foo, Concrete).WillOnce([&foo](const char* str) {
+ return foo.Foo::Concrete(str);
+ });
+```
+
+or tell the mock object that you don't want to mock `Concrete()`:
+
+```cpp
+...
+ ON_CALL(foo, Concrete).WillByDefault([&foo](const char* str) {
+ return foo.Foo::Concrete(str);
+ });
+```
+
+(Why don't we just write `{ return foo.Concrete(str); }`? If you do that,
+`MockFoo::Concrete()` will be called (and cause an infinite recursion) since
+`Foo::Concrete()` is virtual. That's just how C++ works.)
+
+## Using Matchers
+
+### Matching Argument Values Exactly
+
+You can specify exactly which arguments a mock method is expecting:
+
+```cpp
+using ::testing::Return;
+...
+ EXPECT_CALL(foo, DoThis(5))
+ .WillOnce(Return('a'));
+ EXPECT_CALL(foo, DoThat("Hello", bar));
+```
+
+### Using Simple Matchers
+
+You can use matchers to match arguments that have a certain property:
+
+```cpp
+using ::testing::NotNull;
+using ::testing::Return;
+...
+ EXPECT_CALL(foo, DoThis(Ge(5))) // The argument must be >= 5.
+ .WillOnce(Return('a'));
+ EXPECT_CALL(foo, DoThat("Hello", NotNull()));
+ // The second argument must not be NULL.
+```
+
+A frequently used matcher is `_`, which matches anything:
+
+```cpp
+ EXPECT_CALL(foo, DoThat(_, NotNull()));
+```
+
+### Combining Matchers {#CombiningMatchers}
+
+You can build complex matchers from existing ones using `AllOf()`,
+`AllOfArray()`, `AnyOf()`, `AnyOfArray()` and `Not()`:
+
+```cpp
+using ::testing::AllOf;
+using ::testing::Gt;
+using ::testing::HasSubstr;
+using ::testing::Ne;
+using ::testing::Not;
+...
+ // The argument must be > 5 and != 10.
+ EXPECT_CALL(foo, DoThis(AllOf(Gt(5),
+ Ne(10))));
+
+ // The first argument must not contain sub-string "blah".
+ EXPECT_CALL(foo, DoThat(Not(HasSubstr("blah")),
+ NULL));
+```
+
+Matchers are function objects, and parametrized matchers can be composed just
+like any other function. However because their types can be long and rarely
+provide meaningful information, it can be easier to express them with C++14
+generic lambdas to avoid specifying types. For example,
+
+```cpp
+using ::testing::Contains;
+using ::testing::Property;
+
+inline constexpr auto HasFoo = [](const auto& f) {
+ return Property(&MyClass::foo, Contains(f));
+};
+...
+ EXPECT_THAT(x, HasFoo("blah"));
+```
+
+### Casting Matchers {#SafeMatcherCast}
+
+gMock matchers are statically typed, meaning that the compiler can catch your
+mistake if you use a matcher of the wrong type (for example, if you use `Eq(5)`
+to match a `string` argument). Good for you!
+
+Sometimes, however, you know what you're doing and want the compiler to give you
+some slack. One example is that you have a matcher for `long` and the argument
+you want to match is `int`. While the two types aren't exactly the same, there
+is nothing really wrong with using a `Matcher<long>` to match an `int` - after
+all, we can first convert the `int` argument to a `long` losslessly before
+giving it to the matcher.
+
+To support this need, gMock gives you the `SafeMatcherCast<T>(m)` function. It
+casts a matcher `m` to type `Matcher<T>`. To ensure safety, gMock checks that
+(let `U` be the type `m` accepts :
+
+1. Type `T` can be *implicitly* cast to type `U`;
+2. When both `T` and `U` are built-in arithmetic types (`bool`, integers, and
+ floating-point numbers), the conversion from `T` to `U` is not lossy (in
+ other words, any value representable by `T` can also be represented by `U`);
+ and
+3. When `U` is a reference, `T` must also be a reference (as the underlying
+ matcher may be interested in the address of the `U` value).
+
+The code won't compile if any of these conditions isn't met.
+
+Here's one example:
+
+```cpp
+using ::testing::SafeMatcherCast;
+
+// A base class and a child class.
+class Base { ... };
+class Derived : public Base { ... };
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(void, DoThis, (Derived* derived), (override));
+};
+
+...
+ MockFoo foo;
+ // m is a Matcher<Base*> we got from somewhere.
+ EXPECT_CALL(foo, DoThis(SafeMatcherCast<Derived*>(m)));
+```
+
+If you find `SafeMatcherCast<T>(m)` too limiting, you can use a similar function
+`MatcherCast<T>(m)`. The difference is that `MatcherCast` works as long as you
+can `static_cast` type `T` to type `U`.
+
+`MatcherCast` essentially lets you bypass C++'s type system (`static_cast` isn't
+always safe as it could throw away information, for example), so be careful not
+to misuse/abuse it.
+
+### Selecting Between Overloaded Functions {#SelectOverload}
+
+If you expect an overloaded function to be called, the compiler may need some
+help on which overloaded version it is.
+
+To disambiguate functions overloaded on the const-ness of this object, use the
+`Const()` argument wrapper.
+
+```cpp
+using ::testing::ReturnRef;
+
+class MockFoo : public Foo {
+ ...
+ MOCK_METHOD(Bar&, GetBar, (), (override));
+ MOCK_METHOD(const Bar&, GetBar, (), (const, override));
+};
+
+...
+ MockFoo foo;
+ Bar bar1, bar2;
+ EXPECT_CALL(foo, GetBar()) // The non-const GetBar().
+ .WillOnce(ReturnRef(bar1));
+ EXPECT_CALL(Const(foo), GetBar()) // The const GetBar().
+ .WillOnce(ReturnRef(bar2));
+```
+
+(`Const()` is defined by gMock and returns a `const` reference to its argument.)
+
+To disambiguate overloaded functions with the same number of arguments but
+different argument types, you may need to specify the exact type of a matcher,
+either by wrapping your matcher in `Matcher<type>()`, or using a matcher whose
+type is fixed (`TypedEq<type>`, `An<type>()`, etc):
+
+```cpp
+using ::testing::An;
+using ::testing::Matcher;
+using ::testing::TypedEq;
+
+class MockPrinter : public Printer {
+ public:
+ MOCK_METHOD(void, Print, (int n), (override));
+ MOCK_METHOD(void, Print, (char c), (override));
+};
+
+TEST(PrinterTest, Print) {
+ MockPrinter printer;
+
+ EXPECT_CALL(printer, Print(An<int>())); // void Print(int);
+ EXPECT_CALL(printer, Print(Matcher<int>(Lt(5)))); // void Print(int);
+ EXPECT_CALL(printer, Print(TypedEq<char>('a'))); // void Print(char);
+
+ printer.Print(3);
+ printer.Print(6);
+ printer.Print('a');
+}
+```
+
+### Performing Different Actions Based on the Arguments
+
+When a mock method is called, the *last* matching expectation that's still
+active will be selected (think "newer overrides older"). So, you can make a
+method do different things depending on its argument values like this:
+
+```cpp
+using ::testing::_;
+using ::testing::Lt;
+using ::testing::Return;
+...
+ // The default case.
+ EXPECT_CALL(foo, DoThis(_))
+ .WillRepeatedly(Return('b'));
+ // The more specific case.
+ EXPECT_CALL(foo, DoThis(Lt(5)))
+ .WillRepeatedly(Return('a'));
+```
+
+Now, if `foo.DoThis()` is called with a value less than 5, `'a'` will be
+returned; otherwise `'b'` will be returned.
+
+### Matching Multiple Arguments as a Whole
+
+Sometimes it's not enough to match the arguments individually. For example, we
+may want to say that the first argument must be less than the second argument.
+The `With()` clause allows us to match all arguments of a mock function as a
+whole. For example,
+
+```cpp
+using ::testing::_;
+using ::testing::Ne;
+using ::testing::Lt;
+...
+ EXPECT_CALL(foo, InRange(Ne(0), _))
+ .With(Lt());
+```
+
+says that the first argument of `InRange()` must not be 0, and must be less than
+the second argument.
+
+The expression inside `With()` must be a matcher of type `Matcher<std::tuple<A1,
+..., An>>`, where `A1`, ..., `An` are the types of the function arguments.
+
+You can also write `AllArgs(m)` instead of `m` inside `.With()`. The two forms
+are equivalent, but `.With(AllArgs(Lt()))` is more readable than `.With(Lt())`.
+
+You can use `Args<k1, ..., kn>(m)` to match the `n` selected arguments (as a
+tuple) against `m`. For example,
+
+```cpp
+using ::testing::_;
+using ::testing::AllOf;
+using ::testing::Args;
+using ::testing::Lt;
+...
+ EXPECT_CALL(foo, Blah)
+ .With(AllOf(Args<0, 1>(Lt()), Args<1, 2>(Lt())));
+```
+
+says that `Blah` will be called with arguments `x`, `y`, and `z` where `x < y <
+z`. Note that in this example, it wasn't necessary to specify the positional
+matchers.
+
+As a convenience and example, gMock provides some matchers for 2-tuples,
+including the `Lt()` matcher above. See
+[Multi-argument Matchers](reference/matchers.md#MultiArgMatchers) for the
+complete list.
+
+Note that if you want to pass the arguments to a predicate of your own (e.g.
+`.With(Args<0, 1>(Truly(&MyPredicate)))`), that predicate MUST be written to
+take a `std::tuple` as its argument; gMock will pass the `n` selected arguments
+as *one* single tuple to the predicate.
+
+### Using Matchers as Predicates
+
+Have you noticed that a matcher is just a fancy predicate that also knows how to
+describe itself? Many existing algorithms take predicates as arguments (e.g.
+those defined in STL's `<algorithm>` header), and it would be a shame if gMock
+matchers were not allowed to participate.
+
+Luckily, you can use a matcher where a unary predicate functor is expected by
+wrapping it inside the `Matches()` function. For example,
+
+```cpp
+#include <algorithm>
+#include <vector>
+
+using ::testing::Matches;
+using ::testing::Ge;
+
+vector<int> v;
+...
+// How many elements in v are >= 10?
+const int count = count_if(v.begin(), v.end(), Matches(Ge(10)));
+```
+
+Since you can build complex matchers from simpler ones easily using gMock, this
+gives you a way to conveniently construct composite predicates (doing the same
+using STL's `<functional>` header is just painful). For example, here's a
+predicate that's satisfied by any number that is >= 0, <= 100, and != 50:
+
+```cpp
+using testing::AllOf;
+using testing::Ge;
+using testing::Le;
+using testing::Matches;
+using testing::Ne;
+...
+Matches(AllOf(Ge(0), Le(100), Ne(50)))
+```
+
+### Using Matchers in googletest Assertions
+
+See [`EXPECT_THAT`](reference/assertions.md#EXPECT_THAT) in the Assertions
+Reference.
+
+### Using Predicates as Matchers
+
+gMock provides a set of built-in matchers for matching arguments with expected
+values—see the [Matchers Reference](reference/matchers.md) for more information.
+In case you find the built-in set lacking, you can use an arbitrary unary
+predicate function or functor as a matcher - as long as the predicate accepts a
+value of the type you want. You do this by wrapping the predicate inside the
+`Truly()` function, for example:
+
+```cpp
+using ::testing::Truly;
+
+int IsEven(int n) { return (n % 2) == 0 ? 1 : 0; }
+...
+ // Bar() must be called with an even number.
+ EXPECT_CALL(foo, Bar(Truly(IsEven)));
+```
+
+Note that the predicate function / functor doesn't have to return `bool`. It
+works as long as the return value can be used as the condition in in statement
+`if (condition) ...`.
+
+### Matching Arguments that Are Not Copyable
+
+When you do an `EXPECT_CALL(mock_obj, Foo(bar))`, gMock saves away a copy of
+`bar`. When `Foo()` is called later, gMock compares the argument to `Foo()` with
+the saved copy of `bar`. This way, you don't need to worry about `bar` being
+modified or destroyed after the `EXPECT_CALL()` is executed. The same is true
+when you use matchers like `Eq(bar)`, `Le(bar)`, and so on.
+
+But what if `bar` cannot be copied (i.e. has no copy constructor)? You could
+define your own matcher function or callback and use it with `Truly()`, as the
+previous couple of recipes have shown. Or, you may be able to get away from it
+if you can guarantee that `bar` won't be changed after the `EXPECT_CALL()` is
+executed. Just tell gMock that it should save a reference to `bar`, instead of a
+copy of it. Here's how:
+
+```cpp
+using ::testing::Eq;
+using ::testing::Lt;
+...
+ // Expects that Foo()'s argument == bar.
+ EXPECT_CALL(mock_obj, Foo(Eq(std::ref(bar))));
+
+ // Expects that Foo()'s argument < bar.
+ EXPECT_CALL(mock_obj, Foo(Lt(std::ref(bar))));
+```
+
+Remember: if you do this, don't change `bar` after the `EXPECT_CALL()`, or the
+result is undefined.
+
+### Validating a Member of an Object
+
+Often a mock function takes a reference to object as an argument. When matching
+the argument, you may not want to compare the entire object against a fixed
+object, as that may be over-specification. Instead, you may need to validate a
+certain member variable or the result of a certain getter method of the object.
+You can do this with `Field()` and `Property()`. More specifically,
+
+```cpp
+Field(&Foo::bar, m)
+```
+
+is a matcher that matches a `Foo` object whose `bar` member variable satisfies
+matcher `m`.
+
+```cpp
+Property(&Foo::baz, m)
+```
+
+is a matcher that matches a `Foo` object whose `baz()` method returns a value
+that satisfies matcher `m`.
+
+For example:
+
+| Expression | Description |
+| :--------------------------- | :--------------------------------------- |
+| `Field(&Foo::number, Ge(3))` | Matches `x` where `x.number >= 3`. |
+| `Property(&Foo::name, StartsWith("John "))` | Matches `x` where `x.name()` starts with `"John "`. |
+
+Note that in `Property(&Foo::baz, ...)`, method `baz()` must take no argument
+and be declared as `const`. Don't use `Property()` against member functions that
+you do not own, because taking addresses of functions is fragile and generally
+not part of the contract of the function.
+
+`Field()` and `Property()` can also match plain pointers to objects. For
+instance,
+
+```cpp
+using ::testing::Field;
+using ::testing::Ge;
+...
+Field(&Foo::number, Ge(3))
+```
+
+matches a plain pointer `p` where `p->number >= 3`. If `p` is `NULL`, the match
+will always fail regardless of the inner matcher.
+
+What if you want to validate more than one members at the same time? Remember
+that there are [`AllOf()` and `AllOfArray()`](#CombiningMatchers).
+
+Finally `Field()` and `Property()` provide overloads that take the field or
+property names as the first argument to include it in the error message. This
+can be useful when creating combined matchers.
+
+```cpp
+using ::testing::AllOf;
+using ::testing::Field;
+using ::testing::Matcher;
+using ::testing::SafeMatcherCast;
+
+Matcher<Foo> IsFoo(const Foo& foo) {
+ return AllOf(Field("some_field", &Foo::some_field, foo.some_field),
+ Field("other_field", &Foo::other_field, foo.other_field),
+ Field("last_field", &Foo::last_field, foo.last_field));
+}
+```
+
+### Validating the Value Pointed to by a Pointer Argument
+
+C++ functions often take pointers as arguments. You can use matchers like
+`IsNull()`, `NotNull()`, and other comparison matchers to match a pointer, but
+what if you want to make sure the value *pointed to* by the pointer, instead of
+the pointer itself, has a certain property? Well, you can use the `Pointee(m)`
+matcher.
+
+`Pointee(m)` matches a pointer if and only if `m` matches the value the pointer
+points to. For example:
+
+```cpp
+using ::testing::Ge;
+using ::testing::Pointee;
+...
+ EXPECT_CALL(foo, Bar(Pointee(Ge(3))));
+```
+
+expects `foo.Bar()` to be called with a pointer that points to a value greater
+than or equal to 3.
+
+One nice thing about `Pointee()` is that it treats a `NULL` pointer as a match
+failure, so you can write `Pointee(m)` instead of
+
+```cpp
+using ::testing::AllOf;
+using ::testing::NotNull;
+using ::testing::Pointee;
+...
+ AllOf(NotNull(), Pointee(m))
+```
+
+without worrying that a `NULL` pointer will crash your test.
+
+Also, did we tell you that `Pointee()` works with both raw pointers **and**
+smart pointers (`std::unique_ptr`, `std::shared_ptr`, etc)?
+
+What if you have a pointer to pointer? You guessed it - you can use nested
+`Pointee()` to probe deeper inside the value. For example,
+`Pointee(Pointee(Lt(3)))` matches a pointer that points to a pointer that points
+to a number less than 3 (what a mouthful...).
+
+### Testing a Certain Property of an Object
+
+Sometimes you want to specify that an object argument has a certain property,
+but there is no existing matcher that does this. If you want good error
+messages, you should [define a matcher](#NewMatchers). If you want to do it
+quick and dirty, you could get away with writing an ordinary function.
+
+Let's say you have a mock function that takes an object of type `Foo`, which has
+an `int bar()` method and an `int baz()` method, and you want to constrain that
+the argument's `bar()` value plus its `baz()` value is a given number. Here's
+how you can define a matcher to do it:
+
+```cpp
+using ::testing::Matcher;
+
+class BarPlusBazEqMatcher {
+ public:
+ explicit BarPlusBazEqMatcher(int expected_sum)
+ : expected_sum_(expected_sum) {}
+
+ bool MatchAndExplain(const Foo& foo,
+ std::ostream* /* listener */) const {
+ return (foo.bar() + foo.baz()) == expected_sum_;
+ }
+
+ void DescribeTo(std::ostream& os) const {
+ os << "bar() + baz() equals " << expected_sum_;
+ }
+
+ void DescribeNegationTo(std::ostream& os) const {
+ os << "bar() + baz() does not equal " << expected_sum_;
+ }
+ private:
+ const int expected_sum_;
+};
+
+Matcher<const Foo&> BarPlusBazEq(int expected_sum) {
+ return BarPlusBazEqMatcher(expected_sum);
+}
+
+...
+ EXPECT_CALL(..., DoThis(BarPlusBazEq(5)))...;
+```
+
+### Matching Containers
+
+Sometimes an STL container (e.g. list, vector, map, ...) is passed to a mock
+function and you may want to validate it. Since most STL containers support the
+`==` operator, you can write `Eq(expected_container)` or simply
+`expected_container` to match a container exactly.
+
+Sometimes, though, you may want to be more flexible (for example, the first
+element must be an exact match, but the second element can be any positive
+number, and so on). Also, containers used in tests often have a small number of
+elements, and having to define the expected container out-of-line is a bit of a
+hassle.
+
+You can use the `ElementsAre()` or `UnorderedElementsAre()` matcher in such
+cases:
+
+```cpp
+using ::testing::_;
+using ::testing::ElementsAre;
+using ::testing::Gt;
+...
+ MOCK_METHOD(void, Foo, (const vector<int>& numbers), (override));
+...
+ EXPECT_CALL(mock, Foo(ElementsAre(1, Gt(0), _, 5)));
+```
+
+The above matcher says that the container must have 4 elements, which must be 1,
+greater than 0, anything, and 5 respectively.
+
+If you instead write:
+
+```cpp
+using ::testing::_;
+using ::testing::Gt;
+using ::testing::UnorderedElementsAre;
+...
+ MOCK_METHOD(void, Foo, (const vector<int>& numbers), (override));
+...
+ EXPECT_CALL(mock, Foo(UnorderedElementsAre(1, Gt(0), _, 5)));
+```
+
+It means that the container must have 4 elements, which (under some permutation)
+must be 1, greater than 0, anything, and 5 respectively.
+
+As an alternative you can place the arguments in a C-style array and use
+`ElementsAreArray()` or `UnorderedElementsAreArray()` instead:
+
+```cpp
+using ::testing::ElementsAreArray;
+...
+ // ElementsAreArray accepts an array of element values.
+ const int expected_vector1[] = {1, 5, 2, 4, ...};
+ EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector1)));
+
+ // Or, an array of element matchers.
+ Matcher<int> expected_vector2[] = {1, Gt(2), _, 3, ...};
+ EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector2)));
+```
+
+In case the array needs to be dynamically created (and therefore the array size
+cannot be inferred by the compiler), you can give `ElementsAreArray()` an
+additional argument to specify the array size:
+
+```cpp
+using ::testing::ElementsAreArray;
+...
+ int* const expected_vector3 = new int[count];
+ ... fill expected_vector3 with values ...
+ EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector3, count)));
+```
+
+Use `Pair` when comparing maps or other associative containers.
+
+{% raw %}
+
+```cpp
+using testing::ElementsAre;
+using testing::Pair;
+...
+ std::map<string, int> m = {{"a", 1}, {"b", 2}, {"c", 3}};
+ EXPECT_THAT(m, ElementsAre(Pair("a", 1), Pair("b", 2), Pair("c", 3)));
+```
+
+{% endraw %}
+
+**Tips:**
+
+* `ElementsAre*()` can be used to match *any* container that implements the
+ STL iterator pattern (i.e. it has a `const_iterator` type and supports
+ `begin()/end()`), not just the ones defined in STL. It will even work with
+ container types yet to be written - as long as they follows the above
+ pattern.
+* You can use nested `ElementsAre*()` to match nested (multi-dimensional)
+ containers.
+* If the container is passed by pointer instead of by reference, just write
+ `Pointee(ElementsAre*(...))`.
+* The order of elements *matters* for `ElementsAre*()`. If you are using it
+ with containers whose element order are undefined (e.g. `hash_map`) you
+ should use `WhenSorted` around `ElementsAre`.
+
+### Sharing Matchers
+
+Under the hood, a gMock matcher object consists of a pointer to a ref-counted
+implementation object. Copying matchers is allowed and very efficient, as only
+the pointer is copied. When the last matcher that references the implementation
+object dies, the implementation object will be deleted.
+
+Therefore, if you have some complex matcher that you want to use again and
+again, there is no need to build it every time. Just assign it to a matcher
+variable and use that variable repeatedly! For example,
+
+```cpp
+using ::testing::AllOf;
+using ::testing::Gt;
+using ::testing::Le;
+using ::testing::Matcher;
+...
+ Matcher<int> in_range = AllOf(Gt(5), Le(10));
+ ... use in_range as a matcher in multiple EXPECT_CALLs ...
+```
+
+### Matchers must have no side-effects {#PureMatchers}
+
+{: .callout .warning}
+WARNING: gMock does not guarantee when or how many times a matcher will be
+invoked. Therefore, all matchers must be *purely functional*: they cannot have
+any side effects, and the match result must not depend on anything other than
+the matcher's parameters and the value being matched.
+
+This requirement must be satisfied no matter how a matcher is defined (e.g., if
+it is one of the standard matchers, or a custom matcher). In particular, a
+matcher can never call a mock function, as that will affect the state of the
+mock object and gMock.
+
+## Setting Expectations
+
+### Knowing When to Expect {#UseOnCall}
+
+**`ON_CALL`** is likely the *single most under-utilized construct* in gMock.
+
+There are basically two constructs for defining the behavior of a mock object:
+`ON_CALL` and `EXPECT_CALL`. The difference? `ON_CALL` defines what happens when
+a mock method is called, but <em>doesn't imply any expectation on the method
+being called</em>. `EXPECT_CALL` not only defines the behavior, but also sets an
+expectation that <em>the method will be called with the given arguments, for the
+given number of times</em> (and *in the given order* when you specify the order
+too).
+
+Since `EXPECT_CALL` does more, isn't it better than `ON_CALL`? Not really. Every
+`EXPECT_CALL` adds a constraint on the behavior of the code under test. Having
+more constraints than necessary is *baaad* - even worse than not having enough
+constraints.
+
+This may be counter-intuitive. How could tests that verify more be worse than
+tests that verify less? Isn't verification the whole point of tests?
+
+The answer lies in *what* a test should verify. **A good test verifies the
+contract of the code.** If a test over-specifies, it doesn't leave enough
+freedom to the implementation. As a result, changing the implementation without
+breaking the contract (e.g. refactoring and optimization), which should be
+perfectly fine to do, can break such tests. Then you have to spend time fixing
+them, only to see them broken again the next time the implementation is changed.
+
+Keep in mind that one doesn't have to verify more than one property in one test.
+In fact, **it's a good style to verify only one thing in one test.** If you do
+that, a bug will likely break only one or two tests instead of dozens (which
+case would you rather debug?). If you are also in the habit of giving tests
+descriptive names that tell what they verify, you can often easily guess what's
+wrong just from the test log itself.
+
+So use `ON_CALL` by default, and only use `EXPECT_CALL` when you actually intend
+to verify that the call is made. For example, you may have a bunch of `ON_CALL`s
+in your test fixture to set the common mock behavior shared by all tests in the
+same group, and write (scarcely) different `EXPECT_CALL`s in different `TEST_F`s
+to verify different aspects of the code's behavior. Compared with the style
+where each `TEST` has many `EXPECT_CALL`s, this leads to tests that are more
+resilient to implementational changes (and thus less likely to require
+maintenance) and makes the intent of the tests more obvious (so they are easier
+to maintain when you do need to maintain them).
+
+If you are bothered by the "Uninteresting mock function call" message printed
+when a mock method without an `EXPECT_CALL` is called, you may use a `NiceMock`
+instead to suppress all such messages for the mock object, or suppress the
+message for specific methods by adding `EXPECT_CALL(...).Times(AnyNumber())`. DO
+NOT suppress it by blindly adding an `EXPECT_CALL(...)`, or you'll have a test
+that's a pain to maintain.
+
+### Ignoring Uninteresting Calls
+
+If you are not interested in how a mock method is called, just don't say
+anything about it. In this case, if the method is ever called, gMock will
+perform its default action to allow the test program to continue. If you are not
+happy with the default action taken by gMock, you can override it using
+`DefaultValue<T>::Set()` (described [here](#DefaultValue)) or `ON_CALL()`.
+
+Please note that once you expressed interest in a particular mock method (via
+`EXPECT_CALL()`), all invocations to it must match some expectation. If this
+function is called but the arguments don't match any `EXPECT_CALL()` statement,
+it will be an error.
+
+### Disallowing Unexpected Calls
+
+If a mock method shouldn't be called at all, explicitly say so:
+
+```cpp
+using ::testing::_;
+...
+ EXPECT_CALL(foo, Bar(_))
+ .Times(0);
+```
+
+If some calls to the method are allowed, but the rest are not, just list all the
+expected calls:
+
+```cpp
+using ::testing::AnyNumber;
+using ::testing::Gt;
+...
+ EXPECT_CALL(foo, Bar(5));
+ EXPECT_CALL(foo, Bar(Gt(10)))
+ .Times(AnyNumber());
+```
+
+A call to `foo.Bar()` that doesn't match any of the `EXPECT_CALL()` statements
+will be an error.
+
+### Understanding Uninteresting vs Unexpected Calls {#uninteresting-vs-unexpected}
+
+*Uninteresting* calls and *unexpected* calls are different concepts in gMock.
+*Very* different.
+
+A call `x.Y(...)` is **uninteresting** if there's *not even a single*
+`EXPECT_CALL(x, Y(...))` set. In other words, the test isn't interested in the
+`x.Y()` method at all, as evident in that the test doesn't care to say anything
+about it.
+
+A call `x.Y(...)` is **unexpected** if there are *some* `EXPECT_CALL(x,
+Y(...))`s set, but none of them matches the call. Put another way, the test is
+interested in the `x.Y()` method (therefore it explicitly sets some
+`EXPECT_CALL` to verify how it's called); however, the verification fails as the
+test doesn't expect this particular call to happen.
+
+**An unexpected call is always an error,** as the code under test doesn't behave
+the way the test expects it to behave.
+
+**By default, an uninteresting call is not an error,** as it violates no
+constraint specified by the test. (gMock's philosophy is that saying nothing
+means there is no constraint.) However, it leads to a warning, as it *might*
+indicate a problem (e.g. the test author might have forgotten to specify a
+constraint).
+
+In gMock, `NiceMock` and `StrictMock` can be used to make a mock class "nice" or
+"strict". How does this affect uninteresting calls and unexpected calls?
+
+A **nice mock** suppresses uninteresting call *warnings*. It is less chatty than
+the default mock, but otherwise is the same. If a test fails with a default
+mock, it will also fail using a nice mock instead. And vice versa. Don't expect
+making a mock nice to change the test's result.
+
+A **strict mock** turns uninteresting call warnings into errors. So making a
+mock strict may change the test's result.
+
+Let's look at an example:
+
+```cpp
+TEST(...) {
+ NiceMock<MockDomainRegistry> mock_registry;
+ EXPECT_CALL(mock_registry, GetDomainOwner("google.com"))
+ .WillRepeatedly(Return("Larry Page"));
+
+ // Use mock_registry in code under test.
+ ... &mock_registry ...
+}
+```
+
+The sole `EXPECT_CALL` here says that all calls to `GetDomainOwner()` must have
+`"google.com"` as the argument. If `GetDomainOwner("yahoo.com")` is called, it
+will be an unexpected call, and thus an error. *Having a nice mock doesn't
+change the severity of an unexpected call.*
+
+So how do we tell gMock that `GetDomainOwner()` can be called with some other
+arguments as well? The standard technique is to add a "catch all" `EXPECT_CALL`:
+
+```cpp
+ EXPECT_CALL(mock_registry, GetDomainOwner(_))
+ .Times(AnyNumber()); // catches all other calls to this method.
+ EXPECT_CALL(mock_registry, GetDomainOwner("google.com"))
+ .WillRepeatedly(Return("Larry Page"));
+```
+
+Remember that `_` is the wildcard matcher that matches anything. With this, if
+`GetDomainOwner("google.com")` is called, it will do what the second
+`EXPECT_CALL` says; if it is called with a different argument, it will do what
+the first `EXPECT_CALL` says.
+
+Note that the order of the two `EXPECT_CALL`s is important, as a newer
+`EXPECT_CALL` takes precedence over an older one.
+
+For more on uninteresting calls, nice mocks, and strict mocks, read
+["The Nice, the Strict, and the Naggy"](#NiceStrictNaggy).
+
+### Ignoring Uninteresting Arguments {#ParameterlessExpectations}
+
+If your test doesn't care about the parameters (it only cares about the number
+or order of calls), you can often simply omit the parameter list:
+
+```cpp
+ // Expect foo.Bar( ... ) twice with any arguments.
+ EXPECT_CALL(foo, Bar).Times(2);
+
+ // Delegate to the given method whenever the factory is invoked.
+ ON_CALL(foo_factory, MakeFoo)
+ .WillByDefault(&BuildFooForTest);
+```
+
+This functionality is only available when a method is not overloaded; to prevent
+unexpected behavior it is a compilation error to try to set an expectation on a
+method where the specific overload is ambiguous. You can work around this by
+supplying a [simpler mock interface](#SimplerInterfaces) than the mocked class
+provides.
+
+This pattern is also useful when the arguments are interesting, but match logic
+is substantially complex. You can leave the argument list unspecified and use
+SaveArg actions to [save the values for later verification](#SaveArgVerify). If
+you do that, you can easily differentiate calling the method the wrong number of
+times from calling it with the wrong arguments.
+
+### Expecting Ordered Calls {#OrderedCalls}
+
+Although an `EXPECT_CALL()` statement defined later takes precedence when gMock
+tries to match a function call with an expectation, by default calls don't have
+to happen in the order `EXPECT_CALL()` statements are written. For example, if
+the arguments match the matchers in the second `EXPECT_CALL()`, but not those in
+the first and third, then the second expectation will be used.
+
+If you would rather have all calls occur in the order of the expectations, put
+the `EXPECT_CALL()` statements in a block where you define a variable of type
+`InSequence`:
+
+```cpp
+using ::testing::_;
+using ::testing::InSequence;
+
+ {
+ InSequence s;
+
+ EXPECT_CALL(foo, DoThis(5));
+ EXPECT_CALL(bar, DoThat(_))
+ .Times(2);
+ EXPECT_CALL(foo, DoThis(6));
+ }
+```
+
+In this example, we expect a call to `foo.DoThis(5)`, followed by two calls to
+`bar.DoThat()` where the argument can be anything, which are in turn followed by
+a call to `foo.DoThis(6)`. If a call occurred out-of-order, gMock will report an
+error.
+
+### Expecting Partially Ordered Calls {#PartialOrder}
+
+Sometimes requiring everything to occur in a predetermined order can lead to
+brittle tests. For example, we may care about `A` occurring before both `B` and
+`C`, but aren't interested in the relative order of `B` and `C`. In this case,
+the test should reflect our real intent, instead of being overly constraining.
+
+gMock allows you to impose an arbitrary DAG (directed acyclic graph) on the
+calls. One way to express the DAG is to use the
+[`After` clause](reference/mocking.md#EXPECT_CALL.After) of `EXPECT_CALL`.
+
+Another way is via the `InSequence()` clause (not the same as the `InSequence`
+class), which we borrowed from jMock 2. It's less flexible than `After()`, but
+more convenient when you have long chains of sequential calls, as it doesn't
+require you to come up with different names for the expectations in the chains.
+Here's how it works:
+
+If we view `EXPECT_CALL()` statements as nodes in a graph, and add an edge from
+node A to node B wherever A must occur before B, we can get a DAG. We use the
+term "sequence" to mean a directed path in this DAG. Now, if we decompose the
+DAG into sequences, we just need to know which sequences each `EXPECT_CALL()`
+belongs to in order to be able to reconstruct the original DAG.
+
+So, to specify the partial order on the expectations we need to do two things:
+first to define some `Sequence` objects, and then for each `EXPECT_CALL()` say
+which `Sequence` objects it is part of.
+
+Expectations in the same sequence must occur in the order they are written. For
+example,
+
+```cpp
+using ::testing::Sequence;
+...
+ Sequence s1, s2;
+
+ EXPECT_CALL(foo, A())
+ .InSequence(s1, s2);
+ EXPECT_CALL(bar, B())
+ .InSequence(s1);
+ EXPECT_CALL(bar, C())
+ .InSequence(s2);
+ EXPECT_CALL(foo, D())
+ .InSequence(s2);
+```
+
+specifies the following DAG (where `s1` is `A -> B`, and `s2` is `A -> C -> D`):
+
+```text
+ +---> B
+ |
+ A ---|
+ |
+ +---> C ---> D
+```
+
+This means that A must occur before B and C, and C must occur before D. There's
+no restriction about the order other than these.
+
+### Controlling When an Expectation Retires
+
+When a mock method is called, gMock only considers expectations that are still
+active. An expectation is active when created, and becomes inactive (aka
+*retires*) when a call that has to occur later has occurred. For example, in
+
+```cpp
+using ::testing::_;
+using ::testing::Sequence;
+...
+ Sequence s1, s2;
+
+ EXPECT_CALL(log, Log(WARNING, _, "File too large.")) // #1
+ .Times(AnyNumber())
+ .InSequence(s1, s2);
+ EXPECT_CALL(log, Log(WARNING, _, "Data set is empty.")) // #2
+ .InSequence(s1);
+ EXPECT_CALL(log, Log(WARNING, _, "User not found.")) // #3
+ .InSequence(s2);
+```
+
+as soon as either #2 or #3 is matched, #1 will retire. If a warning `"File too
+large."` is logged after this, it will be an error.
+
+Note that an expectation doesn't retire automatically when it's saturated. For
+example,
+
+```cpp
+using ::testing::_;
+...
+ EXPECT_CALL(log, Log(WARNING, _, _)); // #1
+ EXPECT_CALL(log, Log(WARNING, _, "File too large.")); // #2
+```
+
+says that there will be exactly one warning with the message `"File too
+large."`. If the second warning contains this message too, #2 will match again
+and result in an upper-bound-violated error.
+
+If this is not what you want, you can ask an expectation to retire as soon as it
+becomes saturated:
+
+```cpp
+using ::testing::_;
+...
+ EXPECT_CALL(log, Log(WARNING, _, _)); // #1
+ EXPECT_CALL(log, Log(WARNING, _, "File too large.")) // #2
+ .RetiresOnSaturation();
+```
+
+Here #2 can be used only once, so if you have two warnings with the message
+`"File too large."`, the first will match #2 and the second will match #1 -
+there will be no error.
+
+## Using Actions
+
+### Returning References from Mock Methods
+
+If a mock function's return type is a reference, you need to use `ReturnRef()`
+instead of `Return()` to return a result:
+
+```cpp
+using ::testing::ReturnRef;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(Bar&, GetBar, (), (override));
+};
+...
+ MockFoo foo;
+ Bar bar;
+ EXPECT_CALL(foo, GetBar())
+ .WillOnce(ReturnRef(bar));
+...
+```
+
+### Returning Live Values from Mock Methods
+
+The `Return(x)` action saves a copy of `x` when the action is created, and
+always returns the same value whenever it's executed. Sometimes you may want to
+instead return the *live* value of `x` (i.e. its value at the time when the
+action is *executed*.). Use either `ReturnRef()` or `ReturnPointee()` for this
+purpose.
+
+If the mock function's return type is a reference, you can do it using
+`ReturnRef(x)`, as shown in the previous recipe ("Returning References from Mock
+Methods"). However, gMock doesn't let you use `ReturnRef()` in a mock function
+whose return type is not a reference, as doing that usually indicates a user
+error. So, what shall you do?
+
+Though you may be tempted, DO NOT use `std::ref()`:
+
+```cpp
+using testing::Return;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(int, GetValue, (), (override));
+};
+...
+ int x = 0;
+ MockFoo foo;
+ EXPECT_CALL(foo, GetValue())
+ .WillRepeatedly(Return(std::ref(x))); // Wrong!
+ x = 42;
+ EXPECT_EQ(42, foo.GetValue());
+```
+
+Unfortunately, it doesn't work here. The above code will fail with error:
+
+```text
+Value of: foo.GetValue()
+ Actual: 0
+Expected: 42
+```
+
+The reason is that `Return(*value*)` converts `value` to the actual return type
+of the mock function at the time when the action is *created*, not when it is
+*executed*. (This behavior was chosen for the action to be safe when `value` is
+a proxy object that references some temporary objects.) As a result,
+`std::ref(x)` is converted to an `int` value (instead of a `const int&`) when
+the expectation is set, and `Return(std::ref(x))` will always return 0.
+
+`ReturnPointee(pointer)` was provided to solve this problem specifically. It
+returns the value pointed to by `pointer` at the time the action is *executed*:
+
+```cpp
+using testing::ReturnPointee;
+...
+ int x = 0;
+ MockFoo foo;
+ EXPECT_CALL(foo, GetValue())
+ .WillRepeatedly(ReturnPointee(&x)); // Note the & here.
+ x = 42;
+ EXPECT_EQ(42, foo.GetValue()); // This will succeed now.
+```
+
+### Combining Actions
+
+Want to do more than one thing when a function is called? That's fine. `DoAll()`
+allow you to do sequence of actions every time. Only the return value of the
+last action in the sequence will be used.
+
+```cpp
+using ::testing::_;
+using ::testing::DoAll;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(bool, Bar, (int n), (override));
+};
+...
+ EXPECT_CALL(foo, Bar(_))
+ .WillOnce(DoAll(action_1,
+ action_2,
+ ...
+ action_n));
+```
+
+### Verifying Complex Arguments {#SaveArgVerify}
+
+If you want to verify that a method is called with a particular argument but the
+match criteria is complex, it can be difficult to distinguish between
+cardinality failures (calling the method the wrong number of times) and argument
+match failures. Similarly, if you are matching multiple parameters, it may not
+be easy to distinguishing which argument failed to match. For example:
+
+```cpp
+ // Not ideal: this could fail because of a problem with arg1 or arg2, or maybe
+ // just the method wasn't called.
+ EXPECT_CALL(foo, SendValues(_, ElementsAre(1, 4, 4, 7), EqualsProto( ... )));
+```
+
+You can instead save the arguments and test them individually:
+
+```cpp
+ EXPECT_CALL(foo, SendValues)
+ .WillOnce(DoAll(SaveArg<1>(&actual_array), SaveArg<2>(&actual_proto)));
+ ... run the test
+ EXPECT_THAT(actual_array, ElementsAre(1, 4, 4, 7));
+ EXPECT_THAT(actual_proto, EqualsProto( ... ));
+```
+
+### Mocking Side Effects {#MockingSideEffects}
+
+Sometimes a method exhibits its effect not via returning a value but via side
+effects. For example, it may change some global state or modify an output
+argument. To mock side effects, in general you can define your own action by
+implementing `::testing::ActionInterface`.
+
+If all you need to do is to change an output argument, the built-in
+`SetArgPointee()` action is convenient:
+
+```cpp
+using ::testing::_;
+using ::testing::SetArgPointee;
+
+class MockMutator : public Mutator {
+ public:
+ MOCK_METHOD(void, Mutate, (bool mutate, int* value), (override));
+ ...
+}
+...
+ MockMutator mutator;
+ EXPECT_CALL(mutator, Mutate(true, _))
+ .WillOnce(SetArgPointee<1>(5));
+```
+
+In this example, when `mutator.Mutate()` is called, we will assign 5 to the
+`int` variable pointed to by argument #1 (0-based).
+
+`SetArgPointee()` conveniently makes an internal copy of the value you pass to
+it, removing the need to keep the value in scope and alive. The implication
+however is that the value must have a copy constructor and assignment operator.
+
+If the mock method also needs to return a value as well, you can chain
+`SetArgPointee()` with `Return()` using `DoAll()`, remembering to put the
+`Return()` statement last:
+
+```cpp
+using ::testing::_;
+using ::testing::DoAll;
+using ::testing::Return;
+using ::testing::SetArgPointee;
+
+class MockMutator : public Mutator {
+ public:
+ ...
+ MOCK_METHOD(bool, MutateInt, (int* value), (override));
+}
+...
+ MockMutator mutator;
+ EXPECT_CALL(mutator, MutateInt(_))
+ .WillOnce(DoAll(SetArgPointee<0>(5),
+ Return(true)));
+```
+
+Note, however, that if you use the `ReturnOKWith()` method, it will override the
+values provided by `SetArgPointee()` in the response parameters of your function
+call.
+
+If the output argument is an array, use the `SetArrayArgument<N>(first, last)`
+action instead. It copies the elements in source range `[first, last)` to the
+array pointed to by the `N`-th (0-based) argument:
+
+```cpp
+using ::testing::NotNull;
+using ::testing::SetArrayArgument;
+
+class MockArrayMutator : public ArrayMutator {
+ public:
+ MOCK_METHOD(void, Mutate, (int* values, int num_values), (override));
+ ...
+}
+...
+ MockArrayMutator mutator;
+ int values[5] = {1, 2, 3, 4, 5};
+ EXPECT_CALL(mutator, Mutate(NotNull(), 5))
+ .WillOnce(SetArrayArgument<0>(values, values + 5));
+```
+
+This also works when the argument is an output iterator:
+
+```cpp
+using ::testing::_;
+using ::testing::SetArrayArgument;
+
+class MockRolodex : public Rolodex {
+ public:
+ MOCK_METHOD(void, GetNames, (std::back_insert_iterator<vector<string>>),
+ (override));
+ ...
+}
+...
+ MockRolodex rolodex;
+ vector<string> names = {"George", "John", "Thomas"};
+ EXPECT_CALL(rolodex, GetNames(_))
+ .WillOnce(SetArrayArgument<0>(names.begin(), names.end()));
+```
+
+### Changing a Mock Object's Behavior Based on the State
+
+If you expect a call to change the behavior of a mock object, you can use
+`::testing::InSequence` to specify different behaviors before and after the
+call:
+
+```cpp
+using ::testing::InSequence;
+using ::testing::Return;
+
+...
+ {
+ InSequence seq;
+ EXPECT_CALL(my_mock, IsDirty())
+ .WillRepeatedly(Return(true));
+ EXPECT_CALL(my_mock, Flush());
+ EXPECT_CALL(my_mock, IsDirty())
+ .WillRepeatedly(Return(false));
+ }
+ my_mock.FlushIfDirty();
+```
+
+This makes `my_mock.IsDirty()` return `true` before `my_mock.Flush()` is called
+and return `false` afterwards.
+
+If the behavior change is more complex, you can store the effects in a variable
+and make a mock method get its return value from that variable:
+
+```cpp
+using ::testing::_;
+using ::testing::SaveArg;
+using ::testing::Return;
+
+ACTION_P(ReturnPointee, p) { return *p; }
+...
+ int previous_value = 0;
+ EXPECT_CALL(my_mock, GetPrevValue)
+ .WillRepeatedly(ReturnPointee(&previous_value));
+ EXPECT_CALL(my_mock, UpdateValue)
+ .WillRepeatedly(SaveArg<0>(&previous_value));
+ my_mock.DoSomethingToUpdateValue();
+```
+
+Here `my_mock.GetPrevValue()` will always return the argument of the last
+`UpdateValue()` call.
+
+### Setting the Default Value for a Return Type {#DefaultValue}
+
+If a mock method's return type is a built-in C++ type or pointer, by default it
+will return 0 when invoked. Also, in C++ 11 and above, a mock method whose
+return type has a default constructor will return a default-constructed value by
+default. You only need to specify an action if this default value doesn't work
+for you.
+
+Sometimes, you may want to change this default value, or you may want to specify
+a default value for types gMock doesn't know about. You can do this using the
+`::testing::DefaultValue` class template:
+
+```cpp
+using ::testing::DefaultValue;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(Bar, CalculateBar, (), (override));
+};
+
+
+...
+ Bar default_bar;
+ // Sets the default return value for type Bar.
+ DefaultValue<Bar>::Set(default_bar);
+
+ MockFoo foo;
+
+ // We don't need to specify an action here, as the default
+ // return value works for us.
+ EXPECT_CALL(foo, CalculateBar());
+
+ foo.CalculateBar(); // This should return default_bar.
+
+ // Unsets the default return value.
+ DefaultValue<Bar>::Clear();
+```
+
+Please note that changing the default value for a type can make your tests hard
+to understand. We recommend you to use this feature judiciously. For example,
+you may want to make sure the `Set()` and `Clear()` calls are right next to the
+code that uses your mock.
+
+### Setting the Default Actions for a Mock Method
+
+You've learned how to change the default value of a given type. However, this
+may be too coarse for your purpose: perhaps you have two mock methods with the
+same return type and you want them to have different behaviors. The `ON_CALL()`
+macro allows you to customize your mock's behavior at the method level:
+
+```cpp
+using ::testing::_;
+using ::testing::AnyNumber;
+using ::testing::Gt;
+using ::testing::Return;
+...
+ ON_CALL(foo, Sign(_))
+ .WillByDefault(Return(-1));
+ ON_CALL(foo, Sign(0))
+ .WillByDefault(Return(0));
+ ON_CALL(foo, Sign(Gt(0)))
+ .WillByDefault(Return(1));
+
+ EXPECT_CALL(foo, Sign(_))
+ .Times(AnyNumber());
+
+ foo.Sign(5); // This should return 1.
+ foo.Sign(-9); // This should return -1.
+ foo.Sign(0); // This should return 0.
+```
+
+As you may have guessed, when there are more than one `ON_CALL()` statements,
+the newer ones in the order take precedence over the older ones. In other words,
+the **last** one that matches the function arguments will be used. This matching
+order allows you to set up the common behavior in a mock object's constructor or
+the test fixture's set-up phase and specialize the mock's behavior later.
+
+Note that both `ON_CALL` and `EXPECT_CALL` have the same "later statements take
+precedence" rule, but they don't interact. That is, `EXPECT_CALL`s have their
+own precedence order distinct from the `ON_CALL` precedence order.
+
+### Using Functions/Methods/Functors/Lambdas as Actions {#FunctionsAsActions}
+
+If the built-in actions don't suit you, you can use an existing callable
+(function, `std::function`, method, functor, lambda) as an action.
+
+```cpp
+using ::testing::_; using ::testing::Invoke;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(int, Sum, (int x, int y), (override));
+ MOCK_METHOD(bool, ComplexJob, (int x), (override));
+};
+
+int CalculateSum(int x, int y) { return x + y; }
+int Sum3(int x, int y, int z) { return x + y + z; }
+
+class Helper {
+ public:
+ bool ComplexJob(int x);
+};
+
+...
+ MockFoo foo;
+ Helper helper;
+ EXPECT_CALL(foo, Sum(_, _))
+ .WillOnce(&CalculateSum)
+ .WillRepeatedly(Invoke(NewPermanentCallback(Sum3, 1)));
+ EXPECT_CALL(foo, ComplexJob(_))
+ .WillOnce(Invoke(&helper, &Helper::ComplexJob))
+ .WillOnce([] { return true; })
+ .WillRepeatedly([](int x) { return x > 0; });
+
+ foo.Sum(5, 6); // Invokes CalculateSum(5, 6).
+ foo.Sum(2, 3); // Invokes Sum3(1, 2, 3).
+ foo.ComplexJob(10); // Invokes helper.ComplexJob(10).
+ foo.ComplexJob(-1); // Invokes the inline lambda.
+```
+
+The only requirement is that the type of the function, etc must be *compatible*
+with the signature of the mock function, meaning that the latter's arguments (if
+it takes any) can be implicitly converted to the corresponding arguments of the
+former, and the former's return type can be implicitly converted to that of the
+latter. So, you can invoke something whose type is *not* exactly the same as the
+mock function, as long as it's safe to do so - nice, huh?
+
+Note that:
+
+* The action takes ownership of the callback and will delete it when the
+ action itself is destructed.
+* If the type of a callback is derived from a base callback type `C`, you need
+ to implicitly cast it to `C` to resolve the overloading, e.g.
+
+ ```cpp
+ using ::testing::Invoke;
+ ...
+ ResultCallback<bool>* is_ok = ...;
+ ... Invoke(is_ok) ...; // This works.
+
+ BlockingClosure* done = new BlockingClosure;
+ ... Invoke(implicit_cast<Closure*>(done)) ...; // The cast is necessary.
+ ```
+
+### Using Functions with Extra Info as Actions
+
+The function or functor you call using `Invoke()` must have the same number of
+arguments as the mock function you use it for. Sometimes you may have a function
+that takes more arguments, and you are willing to pass in the extra arguments
+yourself to fill the gap. You can do this in gMock using callbacks with
+pre-bound arguments. Here's an example:
+
+```cpp
+using ::testing::Invoke;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(char, DoThis, (int n), (override));
+};
+
+char SignOfSum(int x, int y) {
+ const int sum = x + y;
+ return (sum > 0) ? '+' : (sum < 0) ? '-' : '0';
+}
+
+TEST_F(FooTest, Test) {
+ MockFoo foo;
+
+ EXPECT_CALL(foo, DoThis(2))
+ .WillOnce(Invoke(NewPermanentCallback(SignOfSum, 5)));
+ EXPECT_EQ('+', foo.DoThis(2)); // Invokes SignOfSum(5, 2).
+}
+```
+
+### Invoking a Function/Method/Functor/Lambda/Callback Without Arguments
+
+`Invoke()` passes the mock function's arguments to the function, etc being
+invoked such that the callee has the full context of the call to work with. If
+the invoked function is not interested in some or all of the arguments, it can
+simply ignore them.
+
+Yet, a common pattern is that a test author wants to invoke a function without
+the arguments of the mock function. She could do that using a wrapper function
+that throws away the arguments before invoking an underlining nullary function.
+Needless to say, this can be tedious and obscures the intent of the test.
+
+There are two solutions to this problem. First, you can pass any callable of
+zero args as an action. Alternatively, use `InvokeWithoutArgs()`, which is like
+`Invoke()` except that it doesn't pass the mock function's arguments to the
+callee. Here's an example of each:
+
+```cpp
+using ::testing::_;
+using ::testing::InvokeWithoutArgs;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(bool, ComplexJob, (int n), (override));
+};
+
+bool Job1() { ... }
+bool Job2(int n, char c) { ... }
+
+...
+ MockFoo foo;
+ EXPECT_CALL(foo, ComplexJob(_))
+ .WillOnce([] { Job1(); });
+ .WillOnce(InvokeWithoutArgs(NewPermanentCallback(Job2, 5, 'a')));
+
+ foo.ComplexJob(10); // Invokes Job1().
+ foo.ComplexJob(20); // Invokes Job2(5, 'a').
+```
+
+Note that:
+
+* The action takes ownership of the callback and will delete it when the
+ action itself is destructed.
+* If the type of a callback is derived from a base callback type `C`, you need
+ to implicitly cast it to `C` to resolve the overloading, e.g.
+
+ ```cpp
+ using ::testing::InvokeWithoutArgs;
+ ...
+ ResultCallback<bool>* is_ok = ...;
+ ... InvokeWithoutArgs(is_ok) ...; // This works.
+
+ BlockingClosure* done = ...;
+ ... InvokeWithoutArgs(implicit_cast<Closure*>(done)) ...;
+ // The cast is necessary.
+ ```
+
+### Invoking an Argument of the Mock Function
+
+Sometimes a mock function will receive a function pointer, a functor (in other
+words, a "callable") as an argument, e.g.
+
+```cpp
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(bool, DoThis, (int n, (ResultCallback1<bool, int>* callback)),
+ (override));
+};
+```
+
+and you may want to invoke this callable argument:
+
+```cpp
+using ::testing::_;
+...
+ MockFoo foo;
+ EXPECT_CALL(foo, DoThis(_, _))
+ .WillOnce(...);
+ // Will execute callback->Run(5), where callback is the
+ // second argument DoThis() receives.
+```
+
+{: .callout .note}
+NOTE: The section below is legacy documentation from before C++ had lambdas:
+
+Arghh, you need to refer to a mock function argument but C++ has no lambda
+(yet), so you have to define your own action. :-( Or do you really?
+
+Well, gMock has an action to solve *exactly* this problem:
+
+```cpp
+InvokeArgument<N>(arg_1, arg_2, ..., arg_m)
+```
+
+will invoke the `N`-th (0-based) argument the mock function receives, with
+`arg_1`, `arg_2`, ..., and `arg_m`. No matter if the argument is a function
+pointer, a functor, or a callback. gMock handles them all.
+
+With that, you could write:
+
+```cpp
+using ::testing::_;
+using ::testing::InvokeArgument;
+...
+ EXPECT_CALL(foo, DoThis(_, _))
+ .WillOnce(InvokeArgument<1>(5));
+ // Will execute callback->Run(5), where callback is the
+ // second argument DoThis() receives.
+```
+
+What if the callable takes an argument by reference? No problem - just wrap it
+inside `std::ref()`:
+
+```cpp
+ ...
+ MOCK_METHOD(bool, Bar,
+ ((ResultCallback2<bool, int, const Helper&>* callback)),
+ (override));
+ ...
+ using ::testing::_;
+ using ::testing::InvokeArgument;
+ ...
+ MockFoo foo;
+ Helper helper;
+ ...
+ EXPECT_CALL(foo, Bar(_))
+ .WillOnce(InvokeArgument<0>(5, std::ref(helper)));
+ // std::ref(helper) guarantees that a reference to helper, not a copy of
+ // it, will be passed to the callback.
+```
+
+What if the callable takes an argument by reference and we do **not** wrap the
+argument in `std::ref()`? Then `InvokeArgument()` will *make a copy* of the
+argument, and pass a *reference to the copy*, instead of a reference to the
+original value, to the callable. This is especially handy when the argument is a
+temporary value:
+
+```cpp
+ ...
+ MOCK_METHOD(bool, DoThat, (bool (*f)(const double& x, const string& s)),
+ (override));
+ ...
+ using ::testing::_;
+ using ::testing::InvokeArgument;
+ ...
+ MockFoo foo;
+ ...
+ EXPECT_CALL(foo, DoThat(_))
+ .WillOnce(InvokeArgument<0>(5.0, string("Hi")));
+ // Will execute (*f)(5.0, string("Hi")), where f is the function pointer
+ // DoThat() receives. Note that the values 5.0 and string("Hi") are
+ // temporary and dead once the EXPECT_CALL() statement finishes. Yet
+ // it's fine to perform this action later, since a copy of the values
+ // are kept inside the InvokeArgument action.
+```
+
+### Ignoring an Action's Result
+
+Sometimes you have an action that returns *something*, but you need an action
+that returns `void` (perhaps you want to use it in a mock function that returns
+`void`, or perhaps it needs to be used in `DoAll()` and it's not the last in the
+list). `IgnoreResult()` lets you do that. For example:
+
+```cpp
+using ::testing::_;
+using ::testing::DoAll;
+using ::testing::IgnoreResult;
+using ::testing::Return;
+
+int Process(const MyData& data);
+string DoSomething();
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(void, Abc, (const MyData& data), (override));
+ MOCK_METHOD(bool, Xyz, (), (override));
+};
+
+ ...
+ MockFoo foo;
+ EXPECT_CALL(foo, Abc(_))
+ // .WillOnce(Invoke(Process));
+ // The above line won't compile as Process() returns int but Abc() needs
+ // to return void.
+ .WillOnce(IgnoreResult(Process));
+ EXPECT_CALL(foo, Xyz())
+ .WillOnce(DoAll(IgnoreResult(DoSomething),
+ // Ignores the string DoSomething() returns.
+ Return(true)));
+```
+
+Note that you **cannot** use `IgnoreResult()` on an action that already returns
+`void`. Doing so will lead to ugly compiler errors.
+
+### Selecting an Action's Arguments {#SelectingArgs}
+
+Say you have a mock function `Foo()` that takes seven arguments, and you have a
+custom action that you want to invoke when `Foo()` is called. Trouble is, the
+custom action only wants three arguments:
+
+```cpp
+using ::testing::_;
+using ::testing::Invoke;
+...
+ MOCK_METHOD(bool, Foo,
+ (bool visible, const string& name, int x, int y,
+ (const map<pair<int, int>>), double& weight, double min_weight,
+ double max_wight));
+...
+bool IsVisibleInQuadrant1(bool visible, int x, int y) {
+ return visible && x >= 0 && y >= 0;
+}
+...
+ EXPECT_CALL(mock, Foo)
+ .WillOnce(Invoke(IsVisibleInQuadrant1)); // Uh, won't compile. :-(
+```
+
+To please the compiler God, you need to define an "adaptor" that has the same
+signature as `Foo()` and calls the custom action with the right arguments:
+
+```cpp
+using ::testing::_;
+using ::testing::Invoke;
+...
+bool MyIsVisibleInQuadrant1(bool visible, const string& name, int x, int y,
+ const map<pair<int, int>, double>& weight,
+ double min_weight, double max_wight) {
+ return IsVisibleInQuadrant1(visible, x, y);
+}
+...
+ EXPECT_CALL(mock, Foo)
+ .WillOnce(Invoke(MyIsVisibleInQuadrant1)); // Now it works.
+```
+
+But isn't this awkward?
+
+gMock provides a generic *action adaptor*, so you can spend your time minding
+more important business than writing your own adaptors. Here's the syntax:
+
+```cpp
+WithArgs<N1, N2, ..., Nk>(action)
+```
+
+creates an action that passes the arguments of the mock function at the given
+indices (0-based) to the inner `action` and performs it. Using `WithArgs`, our
+original example can be written as:
+
+```cpp
+using ::testing::_;
+using ::testing::Invoke;
+using ::testing::WithArgs;
+...
+ EXPECT_CALL(mock, Foo)
+ .WillOnce(WithArgs<0, 2, 3>(Invoke(IsVisibleInQuadrant1))); // No need to define your own adaptor.
+```
+
+For better readability, gMock also gives you:
+
+* `WithoutArgs(action)` when the inner `action` takes *no* argument, and
+* `WithArg<N>(action)` (no `s` after `Arg`) when the inner `action` takes
+ *one* argument.
+
+As you may have realized, `InvokeWithoutArgs(...)` is just syntactic sugar for
+`WithoutArgs(Invoke(...))`.
+
+Here are more tips:
+
+* The inner action used in `WithArgs` and friends does not have to be
+ `Invoke()` -- it can be anything.
+* You can repeat an argument in the argument list if necessary, e.g.
+ `WithArgs<2, 3, 3, 5>(...)`.
+* You can change the order of the arguments, e.g. `WithArgs<3, 2, 1>(...)`.
+* The types of the selected arguments do *not* have to match the signature of
+ the inner action exactly. It works as long as they can be implicitly
+ converted to the corresponding arguments of the inner action. For example,
+ if the 4-th argument of the mock function is an `int` and `my_action` takes
+ a `double`, `WithArg<4>(my_action)` will work.
+
+### Ignoring Arguments in Action Functions
+
+The [selecting-an-action's-arguments](#SelectingArgs) recipe showed us one way
+to make a mock function and an action with incompatible argument lists fit
+together. The downside is that wrapping the action in `WithArgs<...>()` can get
+tedious for people writing the tests.
+
+If you are defining a function (or method, functor, lambda, callback) to be used
+with `Invoke*()`, and you are not interested in some of its arguments, an
+alternative to `WithArgs` is to declare the uninteresting arguments as `Unused`.
+This makes the definition less cluttered and less fragile in case the types of
+the uninteresting arguments change. It could also increase the chance the action
+function can be reused. For example, given
+
+```cpp
+ public:
+ MOCK_METHOD(double, Foo, double(const string& label, double x, double y),
+ (override));
+ MOCK_METHOD(double, Bar, (int index, double x, double y), (override));
+```
+
+instead of
+
+```cpp
+using ::testing::_;
+using ::testing::Invoke;
+
+double DistanceToOriginWithLabel(const string& label, double x, double y) {
+ return sqrt(x*x + y*y);
+}
+double DistanceToOriginWithIndex(int index, double x, double y) {
+ return sqrt(x*x + y*y);
+}
+...
+ EXPECT_CALL(mock, Foo("abc", _, _))
+ .WillOnce(Invoke(DistanceToOriginWithLabel));
+ EXPECT_CALL(mock, Bar(5, _, _))
+ .WillOnce(Invoke(DistanceToOriginWithIndex));
+```
+
+you could write
+
+```cpp
+using ::testing::_;
+using ::testing::Invoke;
+using ::testing::Unused;
+
+double DistanceToOrigin(Unused, double x, double y) {
+ return sqrt(x*x + y*y);
+}
+...
+ EXPECT_CALL(mock, Foo("abc", _, _))
+ .WillOnce(Invoke(DistanceToOrigin));
+ EXPECT_CALL(mock, Bar(5, _, _))
+ .WillOnce(Invoke(DistanceToOrigin));
+```
+
+### Sharing Actions
+
+Just like matchers, a gMock action object consists of a pointer to a ref-counted
+implementation object. Therefore copying actions is also allowed and very
+efficient. When the last action that references the implementation object dies,
+the implementation object will be deleted.
+
+If you have some complex action that you want to use again and again, you may
+not have to build it from scratch every time. If the action doesn't have an
+internal state (i.e. if it always does the same thing no matter how many times
+it has been called), you can assign it to an action variable and use that
+variable repeatedly. For example:
+
+```cpp
+using ::testing::Action;
+using ::testing::DoAll;
+using ::testing::Return;
+using ::testing::SetArgPointee;
+...
+ Action<bool(int*)> set_flag = DoAll(SetArgPointee<0>(5),
+ Return(true));
+ ... use set_flag in .WillOnce() and .WillRepeatedly() ...
+```
+
+However, if the action has its own state, you may be surprised if you share the
+action object. Suppose you have an action factory `IncrementCounter(init)` which
+creates an action that increments and returns a counter whose initial value is
+`init`, using two actions created from the same expression and using a shared
+action will exhibit different behaviors. Example:
+
+```cpp
+ EXPECT_CALL(foo, DoThis())
+ .WillRepeatedly(IncrementCounter(0));
+ EXPECT_CALL(foo, DoThat())
+ .WillRepeatedly(IncrementCounter(0));
+ foo.DoThis(); // Returns 1.
+ foo.DoThis(); // Returns 2.
+ foo.DoThat(); // Returns 1 - Blah() uses a different
+ // counter than Bar()'s.
+```
+
+versus
+
+```cpp
+using ::testing::Action;
+...
+ Action<int()> increment = IncrementCounter(0);
+ EXPECT_CALL(foo, DoThis())
+ .WillRepeatedly(increment);
+ EXPECT_CALL(foo, DoThat())
+ .WillRepeatedly(increment);
+ foo.DoThis(); // Returns 1.
+ foo.DoThis(); // Returns 2.
+ foo.DoThat(); // Returns 3 - the counter is shared.
+```
+
+### Testing Asynchronous Behavior
+
+One oft-encountered problem with gMock is that it can be hard to test
+asynchronous behavior. Suppose you had a `EventQueue` class that you wanted to
+test, and you created a separate `EventDispatcher` interface so that you could
+easily mock it out. However, the implementation of the class fired all the
+events on a background thread, which made test timings difficult. You could just
+insert `sleep()` statements and hope for the best, but that makes your test
+behavior nondeterministic. A better way is to use gMock actions and
+`Notification` objects to force your asynchronous test to behave synchronously.
+
+```cpp
+class MockEventDispatcher : public EventDispatcher {
+ MOCK_METHOD(bool, DispatchEvent, (int32), (override));
+};
+
+TEST(EventQueueTest, EnqueueEventTest) {
+ MockEventDispatcher mock_event_dispatcher;
+ EventQueue event_queue(&mock_event_dispatcher);
+
+ const int32 kEventId = 321;
+ absl::Notification done;
+ EXPECT_CALL(mock_event_dispatcher, DispatchEvent(kEventId))
+ .WillOnce([&done] { done.Notify(); });
+
+ event_queue.EnqueueEvent(kEventId);
+ done.WaitForNotification();
+}
+```
+
+In the example above, we set our normal gMock expectations, but then add an
+additional action to notify the `Notification` object. Now we can just call
+`Notification::WaitForNotification()` in the main thread to wait for the
+asynchronous call to finish. After that, our test suite is complete and we can
+safely exit.
+
+{: .callout .note}
+Note: this example has a downside: namely, if the expectation is not satisfied,
+our test will run forever. It will eventually time-out and fail, but it will
+take longer and be slightly harder to debug. To alleviate this problem, you can
+use `WaitForNotificationWithTimeout(ms)` instead of `WaitForNotification()`.
+
+## Misc Recipes on Using gMock
+
+### Mocking Methods That Use Move-Only Types
+
+C++11 introduced *move-only types*. A move-only-typed value can be moved from
+one object to another, but cannot be copied. `std::unique_ptr<T>` is probably
+the most commonly used move-only type.
+
+Mocking a method that takes and/or returns move-only types presents some
+challenges, but nothing insurmountable. This recipe shows you how you can do it.
+Note that the support for move-only method arguments was only introduced to
+gMock in April 2017; in older code, you may find more complex
+[workarounds](#LegacyMoveOnly) for lack of this feature.
+
+Let’s say we are working on a fictional project that lets one post and share
+snippets called “buzzes”. Your code uses these types:
+
+```cpp
+enum class AccessLevel { kInternal, kPublic };
+
+class Buzz {
+ public:
+ explicit Buzz(AccessLevel access) { ... }
+ ...
+};
+
+class Buzzer {
+ public:
+ virtual ~Buzzer() {}
+ virtual std::unique_ptr<Buzz> MakeBuzz(StringPiece text) = 0;
+ virtual bool ShareBuzz(std::unique_ptr<Buzz> buzz, int64_t timestamp) = 0;
+ ...
+};
+```
+
+A `Buzz` object represents a snippet being posted. A class that implements the
+`Buzzer` interface is capable of creating and sharing `Buzz`es. Methods in
+`Buzzer` may return a `unique_ptr<Buzz>` or take a `unique_ptr<Buzz>`. Now we
+need to mock `Buzzer` in our tests.
+
+To mock a method that accepts or returns move-only types, you just use the
+familiar `MOCK_METHOD` syntax as usual:
+
+```cpp
+class MockBuzzer : public Buzzer {
+ public:
+ MOCK_METHOD(std::unique_ptr<Buzz>, MakeBuzz, (StringPiece text), (override));
+ MOCK_METHOD(bool, ShareBuzz, (std::unique_ptr<Buzz> buzz, int64_t timestamp),
+ (override));
+};
+```
+
+Now that we have the mock class defined, we can use it in tests. In the
+following code examples, we assume that we have defined a `MockBuzzer` object
+named `mock_buzzer_`:
+
+```cpp
+ MockBuzzer mock_buzzer_;
+```
+
+First let’s see how we can set expectations on the `MakeBuzz()` method, which
+returns a `unique_ptr<Buzz>`.
+
+As usual, if you set an expectation without an action (i.e. the `.WillOnce()` or
+`.WillRepeatedly()` clause), when that expectation fires, the default action for
+that method will be taken. Since `unique_ptr<>` has a default constructor that
+returns a null `unique_ptr`, that’s what you’ll get if you don’t specify an
+action:
+
+```cpp
+ // Use the default action.
+ EXPECT_CALL(mock_buzzer_, MakeBuzz("hello"));
+
+ // Triggers the previous EXPECT_CALL.
+ EXPECT_EQ(nullptr, mock_buzzer_.MakeBuzz("hello"));
+```
+
+If you are not happy with the default action, you can tweak it as usual; see
+[Setting Default Actions](#OnCall).
+
+If you just need to return a pre-defined move-only value, you can use the
+`Return(ByMove(...))` action:
+
+```cpp
+ // When this fires, the unique_ptr<> specified by ByMove(...) will
+ // be returned.
+ EXPECT_CALL(mock_buzzer_, MakeBuzz("world"))
+ .WillOnce(Return(ByMove(MakeUnique<Buzz>(AccessLevel::kInternal))));
+
+ EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("world"));
+```
+
+Note that `ByMove()` is essential here - if you drop it, the code won’t compile.
+
+Quiz time! What do you think will happen if a `Return(ByMove(...))` action is
+performed more than once (e.g. you write `...
+.WillRepeatedly(Return(ByMove(...)));`)? Come think of it, after the first time
+the action runs, the source value will be consumed (since it’s a move-only
+value), so the next time around, there’s no value to move from -- you’ll get a
+run-time error that `Return(ByMove(...))` can only be run once.
+
+If you need your mock method to do more than just moving a pre-defined value,
+remember that you can always use a lambda or a callable object, which can do
+pretty much anything you want:
+
+```cpp
+ EXPECT_CALL(mock_buzzer_, MakeBuzz("x"))
+ .WillRepeatedly([](StringPiece text) {
+ return MakeUnique<Buzz>(AccessLevel::kInternal);
+ });
+
+ EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("x"));
+ EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("x"));
+```
+
+Every time this `EXPECT_CALL` fires, a new `unique_ptr<Buzz>` will be created
+and returned. You cannot do this with `Return(ByMove(...))`.
+
+That covers returning move-only values; but how do we work with methods
+accepting move-only arguments? The answer is that they work normally, although
+some actions will not compile when any of method's arguments are move-only. You
+can always use `Return`, or a [lambda or functor](#FunctionsAsActions):
+
+```cpp
+ using ::testing::Unused;
+
+ EXPECT_CALL(mock_buzzer_, ShareBuzz(NotNull(), _)).WillOnce(Return(true));
+ EXPECT_TRUE(mock_buzzer_.ShareBuzz(MakeUnique<Buzz>(AccessLevel::kInternal)),
+ 0);
+
+ EXPECT_CALL(mock_buzzer_, ShareBuzz(_, _)).WillOnce(
+ [](std::unique_ptr<Buzz> buzz, Unused) { return buzz != nullptr; });
+ EXPECT_FALSE(mock_buzzer_.ShareBuzz(nullptr, 0));
+```
+
+Many built-in actions (`WithArgs`, `WithoutArgs`,`DeleteArg`, `SaveArg`, ...)
+could in principle support move-only arguments, but the support for this is not
+implemented yet. If this is blocking you, please file a bug.
+
+A few actions (e.g. `DoAll`) copy their arguments internally, so they can never
+work with non-copyable objects; you'll have to use functors instead.
+
+#### Legacy workarounds for move-only types {#LegacyMoveOnly}
+
+Support for move-only function arguments was only introduced to gMock in April
+of 2017. In older code, you may encounter the following workaround for the lack
+of this feature (it is no longer necessary - we're including it just for
+reference):
+
+```cpp
+class MockBuzzer : public Buzzer {
+ public:
+ MOCK_METHOD(bool, DoShareBuzz, (Buzz* buzz, Time timestamp));
+ bool ShareBuzz(std::unique_ptr<Buzz> buzz, Time timestamp) override {
+ return DoShareBuzz(buzz.get(), timestamp);
+ }
+};
+```
+
+The trick is to delegate the `ShareBuzz()` method to a mock method (let’s call
+it `DoShareBuzz()`) that does not take move-only parameters. Then, instead of
+setting expectations on `ShareBuzz()`, you set them on the `DoShareBuzz()` mock
+method:
+
+```cpp
+ MockBuzzer mock_buzzer_;
+ EXPECT_CALL(mock_buzzer_, DoShareBuzz(NotNull(), _));
+
+ // When one calls ShareBuzz() on the MockBuzzer like this, the call is
+ // forwarded to DoShareBuzz(), which is mocked. Therefore this statement
+ // will trigger the above EXPECT_CALL.
+ mock_buzzer_.ShareBuzz(MakeUnique<Buzz>(AccessLevel::kInternal), 0);
+```
+
+### Making the Compilation Faster
+
+Believe it or not, the *vast majority* of the time spent on compiling a mock
+class is in generating its constructor and destructor, as they perform
+non-trivial tasks (e.g. verification of the expectations). What's more, mock
+methods with different signatures have different types and thus their
+constructors/destructors need to be generated by the compiler separately. As a
+result, if you mock many different types of methods, compiling your mock class
+can get really slow.
+
+If you are experiencing slow compilation, you can move the definition of your
+mock class' constructor and destructor out of the class body and into a `.cc`
+file. This way, even if you `#include` your mock class in N files, the compiler
+only needs to generate its constructor and destructor once, resulting in a much
+faster compilation.
+
+Let's illustrate the idea using an example. Here's the definition of a mock
+class before applying this recipe:
+
+```cpp
+// File mock_foo.h.
+...
+class MockFoo : public Foo {
+ public:
+ // Since we don't declare the constructor or the destructor,
+ // the compiler will generate them in every translation unit
+ // where this mock class is used.
+
+ MOCK_METHOD(int, DoThis, (), (override));
+ MOCK_METHOD(bool, DoThat, (const char* str), (override));
+ ... more mock methods ...
+};
+```
+
+After the change, it would look like:
+
+```cpp
+// File mock_foo.h.
+...
+class MockFoo : public Foo {
+ public:
+ // The constructor and destructor are declared, but not defined, here.
+ MockFoo();
+ virtual ~MockFoo();
+
+ MOCK_METHOD(int, DoThis, (), (override));
+ MOCK_METHOD(bool, DoThat, (const char* str), (override));
+ ... more mock methods ...
+};
+```
+
+and
+
+```cpp
+// File mock_foo.cc.
+#include "path/to/mock_foo.h"
+
+// The definitions may appear trivial, but the functions actually do a
+// lot of things through the constructors/destructors of the member
+// variables used to implement the mock methods.
+MockFoo::MockFoo() {}
+MockFoo::~MockFoo() {}
+```
+
+### Forcing a Verification
+
+When it's being destroyed, your friendly mock object will automatically verify
+that all expectations on it have been satisfied, and will generate googletest
+failures if not. This is convenient as it leaves you with one less thing to
+worry about. That is, unless you are not sure if your mock object will be
+destroyed.
+
+How could it be that your mock object won't eventually be destroyed? Well, it
+might be created on the heap and owned by the code you are testing. Suppose
+there's a bug in that code and it doesn't delete the mock object properly - you
+could end up with a passing test when there's actually a bug.
+
+Using a heap checker is a good idea and can alleviate the concern, but its
+implementation is not 100% reliable. So, sometimes you do want to *force* gMock
+to verify a mock object before it is (hopefully) destructed. You can do this
+with `Mock::VerifyAndClearExpectations(&mock_object)`:
+
+```cpp
+TEST(MyServerTest, ProcessesRequest) {
+ using ::testing::Mock;
+
+ MockFoo* const foo = new MockFoo;
+ EXPECT_CALL(*foo, ...)...;
+ // ... other expectations ...
+
+ // server now owns foo.
+ MyServer server(foo);
+ server.ProcessRequest(...);
+
+ // In case that server's destructor will forget to delete foo,
+ // this will verify the expectations anyway.
+ Mock::VerifyAndClearExpectations(foo);
+} // server is destroyed when it goes out of scope here.
+```
+
+{: .callout .tip}
+**Tip:** The `Mock::VerifyAndClearExpectations()` function returns a `bool` to
+indicate whether the verification was successful (`true` for yes), so you can
+wrap that function call inside a `ASSERT_TRUE()` if there is no point going
+further when the verification has failed.
+
+Do not set new expectations after verifying and clearing a mock after its use.
+Setting expectations after code that exercises the mock has undefined behavior.
+See [Using Mocks in Tests](gmock_for_dummies.md#using-mocks-in-tests) for more
+information.
+
+### Using Checkpoints {#UsingCheckPoints}
+
+Sometimes you might want to test a mock object's behavior in phases whose sizes
+are each manageable, or you might want to set more detailed expectations about
+which API calls invoke which mock functions.
+
+A technique you can use is to put the expectations in a sequence and insert
+calls to a dummy "checkpoint" function at specific places. Then you can verify
+that the mock function calls do happen at the right time. For example, if you
+are exercising the code:
+
+```cpp
+ Foo(1);
+ Foo(2);
+ Foo(3);
+```
+
+and want to verify that `Foo(1)` and `Foo(3)` both invoke `mock.Bar("a")`, but
+`Foo(2)` doesn't invoke anything, you can write:
+
+```cpp
+using ::testing::MockFunction;
+
+TEST(FooTest, InvokesBarCorrectly) {
+ MyMock mock;
+ // Class MockFunction<F> has exactly one mock method. It is named
+ // Call() and has type F.
+ MockFunction<void(string check_point_name)> check;
+ {
+ InSequence s;
+
+ EXPECT_CALL(mock, Bar("a"));
+ EXPECT_CALL(check, Call("1"));
+ EXPECT_CALL(check, Call("2"));
+ EXPECT_CALL(mock, Bar("a"));
+ }
+ Foo(1);
+ check.Call("1");
+ Foo(2);
+ check.Call("2");
+ Foo(3);
+}
+```
+
+The expectation spec says that the first `Bar("a")` call must happen before
+checkpoint "1", the second `Bar("a")` call must happen after checkpoint "2", and
+nothing should happen between the two checkpoints. The explicit checkpoints make
+it clear which `Bar("a")` is called by which call to `Foo()`.
+
+### Mocking Destructors
+
+Sometimes you want to make sure a mock object is destructed at the right time,
+e.g. after `bar->A()` is called but before `bar->B()` is called. We already know
+that you can specify constraints on the [order](#OrderedCalls) of mock function
+calls, so all we need to do is to mock the destructor of the mock function.
+
+This sounds simple, except for one problem: a destructor is a special function
+with special syntax and special semantics, and the `MOCK_METHOD` macro doesn't
+work for it:
+
+```cpp
+MOCK_METHOD(void, ~MockFoo, ()); // Won't compile!
+```
+
+The good news is that you can use a simple pattern to achieve the same effect.
+First, add a mock function `Die()` to your mock class and call it in the
+destructor, like this:
+
+```cpp
+class MockFoo : public Foo {
+ ...
+ // Add the following two lines to the mock class.
+ MOCK_METHOD(void, Die, ());
+ ~MockFoo() override { Die(); }
+};
+```
+
+(If the name `Die()` clashes with an existing symbol, choose another name.) Now,
+we have translated the problem of testing when a `MockFoo` object dies to
+testing when its `Die()` method is called:
+
+```cpp
+ MockFoo* foo = new MockFoo;
+ MockBar* bar = new MockBar;
+ ...
+ {
+ InSequence s;
+
+ // Expects *foo to die after bar->A() and before bar->B().
+ EXPECT_CALL(*bar, A());
+ EXPECT_CALL(*foo, Die());
+ EXPECT_CALL(*bar, B());
+ }
+```
+
+And that's that.
+
+### Using gMock and Threads {#UsingThreads}
+
+In a **unit** test, it's best if you could isolate and test a piece of code in a
+single-threaded context. That avoids race conditions and dead locks, and makes
+debugging your test much easier.
+
+Yet most programs are multi-threaded, and sometimes to test something we need to
+pound on it from more than one thread. gMock works for this purpose too.
+
+Remember the steps for using a mock:
+
+1. Create a mock object `foo`.
+2. Set its default actions and expectations using `ON_CALL()` and
+ `EXPECT_CALL()`.
+3. The code under test calls methods of `foo`.
+4. Optionally, verify and reset the mock.
+5. Destroy the mock yourself, or let the code under test destroy it. The
+ destructor will automatically verify it.
+
+If you follow the following simple rules, your mocks and threads can live
+happily together:
+
+* Execute your *test code* (as opposed to the code being tested) in *one*
+ thread. This makes your test easy to follow.
+* Obviously, you can do step #1 without locking.
+* When doing step #2 and #5, make sure no other thread is accessing `foo`.
+ Obvious too, huh?
+* #3 and #4 can be done either in one thread or in multiple threads - anyway
+ you want. gMock takes care of the locking, so you don't have to do any -
+ unless required by your test logic.
+
+If you violate the rules (for example, if you set expectations on a mock while
+another thread is calling its methods), you get undefined behavior. That's not
+fun, so don't do it.
+
+gMock guarantees that the action for a mock function is done in the same thread
+that called the mock function. For example, in
+
+```cpp
+ EXPECT_CALL(mock, Foo(1))
+ .WillOnce(action1);
+ EXPECT_CALL(mock, Foo(2))
+ .WillOnce(action2);
+```
+
+if `Foo(1)` is called in thread 1 and `Foo(2)` is called in thread 2, gMock will
+execute `action1` in thread 1 and `action2` in thread 2.
+
+gMock does *not* impose a sequence on actions performed in different threads
+(doing so may create deadlocks as the actions may need to cooperate). This means
+that the execution of `action1` and `action2` in the above example *may*
+interleave. If this is a problem, you should add proper synchronization logic to
+`action1` and `action2` to make the test thread-safe.
+
+Also, remember that `DefaultValue<T>` is a global resource that potentially
+affects *all* living mock objects in your program. Naturally, you won't want to
+mess with it from multiple threads or when there still are mocks in action.
+
+### Controlling How Much Information gMock Prints
+
+When gMock sees something that has the potential of being an error (e.g. a mock
+function with no expectation is called, a.k.a. an uninteresting call, which is
+allowed but perhaps you forgot to explicitly ban the call), it prints some
+warning messages, including the arguments of the function, the return value, and
+the stack trace. Hopefully this will remind you to take a look and see if there
+is indeed a problem.
+
+Sometimes you are confident that your tests are correct and may not appreciate
+such friendly messages. Some other times, you are debugging your tests or
+learning about the behavior of the code you are testing, and wish you could
+observe every mock call that happens (including argument values, the return
+value, and the stack trace). Clearly, one size doesn't fit all.
+
+You can control how much gMock tells you using the `--gmock_verbose=LEVEL`
+command-line flag, where `LEVEL` is a string with three possible values:
+
+* `info`: gMock will print all informational messages, warnings, and errors
+ (most verbose). At this setting, gMock will also log any calls to the
+ `ON_CALL/EXPECT_CALL` macros. It will include a stack trace in
+ "uninteresting call" warnings.
+* `warning`: gMock will print both warnings and errors (less verbose); it will
+ omit the stack traces in "uninteresting call" warnings. This is the default.
+* `error`: gMock will print errors only (least verbose).
+
+Alternatively, you can adjust the value of that flag from within your tests like
+so:
+
+```cpp
+ ::testing::FLAGS_gmock_verbose = "error";
+```
+
+If you find gMock printing too many stack frames with its informational or
+warning messages, remember that you can control their amount with the
+`--gtest_stack_trace_depth=max_depth` flag.
+
+Now, judiciously use the right flag to enable gMock serve you better!
+
+### Gaining Super Vision into Mock Calls
+
+You have a test using gMock. It fails: gMock tells you some expectations aren't
+satisfied. However, you aren't sure why: Is there a typo somewhere in the
+matchers? Did you mess up the order of the `EXPECT_CALL`s? Or is the code under
+test doing something wrong? How can you find out the cause?
+
+Won't it be nice if you have X-ray vision and can actually see the trace of all
+`EXPECT_CALL`s and mock method calls as they are made? For each call, would you
+like to see its actual argument values and which `EXPECT_CALL` gMock thinks it
+matches? If you still need some help to figure out who made these calls, how
+about being able to see the complete stack trace at each mock call?
+
+You can unlock this power by running your test with the `--gmock_verbose=info`
+flag. For example, given the test program:
+
+```cpp
+#include "gmock/gmock.h"
+
+using testing::_;
+using testing::HasSubstr;
+using testing::Return;
+
+class MockFoo {
+ public:
+ MOCK_METHOD(void, F, (const string& x, const string& y));
+};
+
+TEST(Foo, Bar) {
+ MockFoo mock;
+ EXPECT_CALL(mock, F(_, _)).WillRepeatedly(Return());
+ EXPECT_CALL(mock, F("a", "b"));
+ EXPECT_CALL(mock, F("c", HasSubstr("d")));
+
+ mock.F("a", "good");
+ mock.F("a", "b");
+}
+```
+
+if you run it with `--gmock_verbose=info`, you will see this output:
+
+```shell
+[ RUN ] Foo.Bar
+
+foo_test.cc:14: EXPECT_CALL(mock, F(_, _)) invoked
+Stack trace: ...
+
+foo_test.cc:15: EXPECT_CALL(mock, F("a", "b")) invoked
+Stack trace: ...
+
+foo_test.cc:16: EXPECT_CALL(mock, F("c", HasSubstr("d"))) invoked
+Stack trace: ...
+
+foo_test.cc:14: Mock function call matches EXPECT_CALL(mock, F(_, _))...
+ Function call: F(@0x7fff7c8dad40"a",@0x7fff7c8dad10"good")
+Stack trace: ...
+
+foo_test.cc:15: Mock function call matches EXPECT_CALL(mock, F("a", "b"))...
+ Function call: F(@0x7fff7c8dada0"a",@0x7fff7c8dad70"b")
+Stack trace: ...
+
+foo_test.cc:16: Failure
+Actual function call count doesn't match EXPECT_CALL(mock, F("c", HasSubstr("d")))...
+ Expected: to be called once
+ Actual: never called - unsatisfied and active
+[ FAILED ] Foo.Bar
+```
+
+Suppose the bug is that the `"c"` in the third `EXPECT_CALL` is a typo and
+should actually be `"a"`. With the above message, you should see that the actual
+`F("a", "good")` call is matched by the first `EXPECT_CALL`, not the third as
+you thought. From that it should be obvious that the third `EXPECT_CALL` is
+written wrong. Case solved.
+
+If you are interested in the mock call trace but not the stack traces, you can
+combine `--gmock_verbose=info` with `--gtest_stack_trace_depth=0` on the test
+command line.
+
+### Running Tests in Emacs
+
+If you build and run your tests in Emacs using the `M-x google-compile` command
+(as many googletest users do), the source file locations of gMock and googletest
+errors will be highlighted. Just press `<Enter>` on one of them and you'll be
+taken to the offending line. Or, you can just type `C-x`` to jump to the next
+error.
+
+To make it even easier, you can add the following lines to your `~/.emacs` file:
+
+```text
+(global-set-key "\M-m" 'google-compile) ; m is for make
+(global-set-key [M-down] 'next-error)
+(global-set-key [M-up] '(lambda () (interactive) (next-error -1)))
+```
+
+Then you can type `M-m` to start a build (if you want to run the test as well,
+just make sure `foo_test.run` or `runtests` is in the build command you supply
+after typing `M-m`), or `M-up`/`M-down` to move back and forth between errors.
+
+## Extending gMock
+
+### Writing New Matchers Quickly {#NewMatchers}
+
+{: .callout .warning}
+WARNING: gMock does not guarantee when or how many times a matcher will be
+invoked. Therefore, all matchers must be functionally pure. See
+[this section](#PureMatchers) for more details.
+
+The `MATCHER*` family of macros can be used to define custom matchers easily.
+The syntax:
+
+```cpp
+MATCHER(name, description_string_expression) { statements; }
+```
+
+will define a matcher with the given name that executes the statements, which
+must return a `bool` to indicate if the match succeeds. Inside the statements,
+you can refer to the value being matched by `arg`, and refer to its type by
+`arg_type`.
+
+The *description string* is a `string`-typed expression that documents what the
+matcher does, and is used to generate the failure message when the match fails.
+It can (and should) reference the special `bool` variable `negation`, and should
+evaluate to the description of the matcher when `negation` is `false`, or that
+of the matcher's negation when `negation` is `true`.
+
+For convenience, we allow the description string to be empty (`""`), in which
+case gMock will use the sequence of words in the matcher name as the
+description.
+
+For example:
+
+```cpp
+MATCHER(IsDivisibleBy7, "") { return (arg % 7) == 0; }
+```
+
+allows you to write
+
+```cpp
+ // Expects mock_foo.Bar(n) to be called where n is divisible by 7.
+ EXPECT_CALL(mock_foo, Bar(IsDivisibleBy7()));
+```
+
+or,
+
+```cpp
+ using ::testing::Not;
+ ...
+ // Verifies that a value is divisible by 7 and the other is not.
+ EXPECT_THAT(some_expression, IsDivisibleBy7());
+ EXPECT_THAT(some_other_expression, Not(IsDivisibleBy7()));
+```
+
+If the above assertions fail, they will print something like:
+
+```shell
+ Value of: some_expression
+ Expected: is divisible by 7
+ Actual: 27
+ ...
+ Value of: some_other_expression
+ Expected: not (is divisible by 7)
+ Actual: 21
+```
+
+where the descriptions `"is divisible by 7"` and `"not (is divisible by 7)"` are
+automatically calculated from the matcher name `IsDivisibleBy7`.
+
+As you may have noticed, the auto-generated descriptions (especially those for
+the negation) may not be so great. You can always override them with a `string`
+expression of your own:
+
+```cpp
+MATCHER(IsDivisibleBy7,
+ absl::StrCat(negation ? "isn't" : "is", " divisible by 7")) {
+ return (arg % 7) == 0;
+}
+```
+
+Optionally, you can stream additional information to a hidden argument named
+`result_listener` to explain the match result. For example, a better definition
+of `IsDivisibleBy7` is:
+
+```cpp
+MATCHER(IsDivisibleBy7, "") {
+ if ((arg % 7) == 0)
+ return true;
+
+ *result_listener << "the remainder is " << (arg % 7);
+ return false;
+}
+```
+
+With this definition, the above assertion will give a better message:
+
+```shell
+ Value of: some_expression
+ Expected: is divisible by 7
+ Actual: 27 (the remainder is 6)
+```
+
+You should let `MatchAndExplain()` print *any additional information* that can
+help a user understand the match result. Note that it should explain why the
+match succeeds in case of a success (unless it's obvious) - this is useful when
+the matcher is used inside `Not()`. There is no need to print the argument value
+itself, as gMock already prints it for you.
+
+{: .callout .note}
+NOTE: The type of the value being matched (`arg_type`) is determined by the
+context in which you use the matcher and is supplied to you by the compiler, so
+you don't need to worry about declaring it (nor can you). This allows the
+matcher to be polymorphic. For example, `IsDivisibleBy7()` can be used to match
+any type where the value of `(arg % 7) == 0` can be implicitly converted to a
+`bool`. In the `Bar(IsDivisibleBy7())` example above, if method `Bar()` takes an
+`int`, `arg_type` will be `int`; if it takes an `unsigned long`, `arg_type` will
+be `unsigned long`; and so on.
+
+### Writing New Parameterized Matchers Quickly
+
+Sometimes you'll want to define a matcher that has parameters. For that you can
+use the macro:
+
+```cpp
+MATCHER_P(name, param_name, description_string) { statements; }
+```
+
+where the description string can be either `""` or a `string` expression that
+references `negation` and `param_name`.
+
+For example:
+
+```cpp
+MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
+```
+
+will allow you to write:
+
+```cpp
+ EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
+```
+
+which may lead to this message (assuming `n` is 10):
+
+```shell
+ Value of: Blah("a")
+ Expected: has absolute value 10
+ Actual: -9
+```
+
+Note that both the matcher description and its parameter are printed, making the
+message human-friendly.
+
+In the matcher definition body, you can write `foo_type` to reference the type
+of a parameter named `foo`. For example, in the body of
+`MATCHER_P(HasAbsoluteValue, value)` above, you can write `value_type` to refer
+to the type of `value`.
+
+gMock also provides `MATCHER_P2`, `MATCHER_P3`, ..., up to `MATCHER_P10` to
+support multi-parameter matchers:
+
+```cpp
+MATCHER_Pk(name, param_1, ..., param_k, description_string) { statements; }
+```
+
+Please note that the custom description string is for a particular *instance* of
+the matcher, where the parameters have been bound to actual values. Therefore
+usually you'll want the parameter values to be part of the description. gMock
+lets you do that by referencing the matcher parameters in the description string
+expression.
+
+For example,
+
+```cpp
+using ::testing::PrintToString;
+MATCHER_P2(InClosedRange, low, hi,
+ absl::StrFormat("%s in range [%s, %s]", negation ? "isn't" : "is",
+ PrintToString(low), PrintToString(hi))) {
+ return low <= arg && arg <= hi;
+}
+...
+EXPECT_THAT(3, InClosedRange(4, 6));
+```
+
+would generate a failure that contains the message:
+
+```shell
+ Expected: is in range [4, 6]
+```
+
+If you specify `""` as the description, the failure message will contain the
+sequence of words in the matcher name followed by the parameter values printed
+as a tuple. For example,
+
+```cpp
+ MATCHER_P2(InClosedRange, low, hi, "") { ... }
+ ...
+ EXPECT_THAT(3, InClosedRange(4, 6));
+```
+
+would generate a failure that contains the text:
+
+```shell
+ Expected: in closed range (4, 6)
+```
+
+For the purpose of typing, you can view
+
+```cpp
+MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
+```
+
+as shorthand for
+
+```cpp
+template <typename p1_type, ..., typename pk_type>
+FooMatcherPk<p1_type, ..., pk_type>
+Foo(p1_type p1, ..., pk_type pk) { ... }
+```
+
+When you write `Foo(v1, ..., vk)`, the compiler infers the types of the
+parameters `v1`, ..., and `vk` for you. If you are not happy with the result of
+the type inference, you can specify the types by explicitly instantiating the
+template, as in `Foo<long, bool>(5, false)`. As said earlier, you don't get to
+(or need to) specify `arg_type` as that's determined by the context in which the
+matcher is used.
+
+You can assign the result of expression `Foo(p1, ..., pk)` to a variable of type
+`FooMatcherPk<p1_type, ..., pk_type>`. This can be useful when composing
+matchers. Matchers that don't have a parameter or have only one parameter have
+special types: you can assign `Foo()` to a `FooMatcher`-typed variable, and
+assign `Foo(p)` to a `FooMatcherP<p_type>`-typed variable.
+
+While you can instantiate a matcher template with reference types, passing the
+parameters by pointer usually makes your code more readable. If, however, you
+still want to pass a parameter by reference, be aware that in the failure
+message generated by the matcher you will see the value of the referenced object
+but not its address.
+
+You can overload matchers with different numbers of parameters:
+
+```cpp
+MATCHER_P(Blah, a, description_string_1) { ... }
+MATCHER_P2(Blah, a, b, description_string_2) { ... }
+```
+
+While it's tempting to always use the `MATCHER*` macros when defining a new
+matcher, you should also consider implementing the matcher interface directly
+instead (see the recipes that follow), especially if you need to use the matcher
+a lot. While these approaches require more work, they give you more control on
+the types of the value being matched and the matcher parameters, which in
+general leads to better compiler error messages that pay off in the long run.
+They also allow overloading matchers based on parameter types (as opposed to
+just based on the number of parameters).
+
+### Writing New Monomorphic Matchers
+
+A matcher of argument type `T` implements the matcher interface for `T` and does
+two things: it tests whether a value of type `T` matches the matcher, and can
+describe what kind of values it matches. The latter ability is used for
+generating readable error messages when expectations are violated.
+
+A matcher of `T` must declare a typedef like:
+
+```cpp
+using is_gtest_matcher = void;
+```
+
+and supports the following operations:
+
+```cpp
+// Match a value and optionally explain into an ostream.
+bool matched = matcher.MatchAndExplain(value, maybe_os);
+// where `value` is of type `T` and
+// `maybe_os` is of type `std::ostream*`, where it can be null if the caller
+// is not interested in there textual explanation.
+
+matcher.DescribeTo(os);
+matcher.DescribeNegationTo(os);
+// where `os` is of type `std::ostream*`.
+```
+
+If you need a custom matcher but `Truly()` is not a good option (for example,
+you may not be happy with the way `Truly(predicate)` describes itself, or you
+may want your matcher to be polymorphic as `Eq(value)` is), you can define a
+matcher to do whatever you want in two steps: first implement the matcher
+interface, and then define a factory function to create a matcher instance. The
+second step is not strictly needed but it makes the syntax of using the matcher
+nicer.
+
+For example, you can define a matcher to test whether an `int` is divisible by 7
+and then use it like this:
+
+```cpp
+using ::testing::Matcher;
+
+class DivisibleBy7Matcher {
+ public:
+ using is_gtest_matcher = void;
+
+ bool MatchAndExplain(int n, std::ostream*) const {
+ return (n % 7) == 0;
+ }
+
+ void DescribeTo(std::ostream* os) const {
+ *os << "is divisible by 7";
+ }
+
+ void DescribeNegationTo(std::ostream* os) const {
+ *os << "is not divisible by 7";
+ }
+};
+
+Matcher<int> DivisibleBy7() {
+ return DivisibleBy7Matcher();
+}
+
+...
+ EXPECT_CALL(foo, Bar(DivisibleBy7()));
+```
+
+You may improve the matcher message by streaming additional information to the
+`os` argument in `MatchAndExplain()`:
+
+```cpp
+class DivisibleBy7Matcher {
+ public:
+ bool MatchAndExplain(int n, std::ostream* os) const {
+ const int remainder = n % 7;
+ if (remainder != 0 && os != nullptr) {
+ *os << "the remainder is " << remainder;
+ }
+ return remainder == 0;
+ }
+ ...
+};
+```
+
+Then, `EXPECT_THAT(x, DivisibleBy7());` may generate a message like this:
+
+```shell
+Value of: x
+Expected: is divisible by 7
+ Actual: 23 (the remainder is 2)
+```
+
+{: .callout .tip}
+Tip: for convenience, `MatchAndExplain()` can take a `MatchResultListener*`
+instead of `std::ostream*`.
+
+### Writing New Polymorphic Matchers
+
+Expanding what we learned above to *polymorphic* matchers is now just as simple
+as adding templates in the right place.
+
+```cpp
+
+class NotNullMatcher {
+ public:

+};
+
+NotNullMatcher NotNull() {
+ return NotNullMatcher();
+}
+
+...
+
+ EXPECT_CALL(foo, Bar(NotNull())); // The argument must be a non-NULL pointer.
+```
+
+### Legacy Matcher Implementation
+
+Defining matchers used to be somewhat more complicated, in which it required
+several supporting classes and virtual functions. To implement a matcher for
+type `T` using the legacy API you have to derive from `MatcherInterface<T>` and
+call `MakeMatcher` to construct the object.
+
+The interface looks like this:
+
+```cpp
+class MatchResultListener {
+ public:
+ ...
+ // Streams x to the underlying ostream; does nothing if the ostream
+ // is NULL.
+ template <typename T>
+ MatchResultListener& operator<<(const T& x);
+
+ // Returns the underlying ostream.
+ std::ostream* stream();
+};
+
+template <typename T>
+class MatcherInterface {
+ public:
+ virtual ~MatcherInterface();
+
+ // Returns true if and only if the matcher matches x; also explains the match
+ // result to 'listener'.
+ virtual bool MatchAndExplain(T x, MatchResultListener* listener) const = 0;
+
+ // Describes this matcher to an ostream.
+ virtual void DescribeTo(std::ostream* os) const = 0;
+
+ // Describes the negation of this matcher to an ostream.
+ virtual void DescribeNegationTo(std::ostream* os) const;
+};
+```
+
+Fortunately, most of the time you can define a polymorphic matcher easily with
+the help of `MakePolymorphicMatcher()`. Here's how you can define `NotNull()` as
+an example:
+
+```cpp
+using ::testing::MakePolymorphicMatcher;
+using ::testing::MatchResultListener;
+using ::testing::PolymorphicMatcher;
+
+class NotNullMatcher {
+ public:
+ // To implement a polymorphic matcher, first define a COPYABLE class
+ // that has three members MatchAndExplain(), DescribeTo(), and
+ // DescribeNegationTo(), like the following.
+
+ // In this example, we want to use NotNull() with any pointer, so
+ // MatchAndExplain() accepts a pointer of any type as its first argument.
+ // In general, you can define MatchAndExplain() as an ordinary method or
+ // a method template, or even overload it.
+ template <typename T>
+ bool MatchAndExplain(T* p,
+ MatchResultListener* /* listener */) const {
+ return p != NULL;
+ }
+
+ // Describes the property of a value matching this matcher.
+ void DescribeTo(std::ostream* os) const { *os << "is not NULL"; }
+
+ // Describes the property of a value NOT matching this matcher.
+ void DescribeNegationTo(std::ostream* os) const { *os << "is NULL"; }
+};
+
+// To construct a polymorphic matcher, pass an instance of the class
+// to MakePolymorphicMatcher(). Note the return type.
+PolymorphicMatcher<NotNullMatcher> NotNull() {
+ return MakePolymorphicMatcher(NotNullMatcher());
+}
+
+...
+
+ EXPECT_CALL(foo, Bar(NotNull())); // The argument must be a non-NULL pointer.
+```
+
+{: .callout .note}
+**Note:** Your polymorphic matcher class does **not** need to inherit from
+`MatcherInterface` or any other class, and its methods do **not** need to be
+virtual.
+
+Like in a monomorphic matcher, you may explain the match result by streaming
+additional information to the `listener` argument in `MatchAndExplain()`.
+
+### Writing New Cardinalities
+
+A cardinality is used in `Times()` to tell gMock how many times you expect a
+call to occur. It doesn't have to be exact. For example, you can say
+`AtLeast(5)` or `Between(2, 4)`.
+
+If the [built-in set](gmock_cheat_sheet.md#CardinalityList) of cardinalities
+doesn't suit you, you are free to define your own by implementing the following
+interface (in namespace `testing`):
+
+```cpp
+class CardinalityInterface {
+ public:
+ virtual ~CardinalityInterface();
+
+ // Returns true if and only if call_count calls will satisfy this cardinality.
+ virtual bool IsSatisfiedByCallCount(int call_count) const = 0;
+
+ // Returns true if and only if call_count calls will saturate this
+ // cardinality.
+ virtual bool IsSaturatedByCallCount(int call_count) const = 0;
+
+ // Describes self to an ostream.
+ virtual void DescribeTo(std::ostream* os) const = 0;
+};
+```
+
+For example, to specify that a call must occur even number of times, you can
+write
+
+```cpp
+using ::testing::Cardinality;
+using ::testing::CardinalityInterface;
+using ::testing::MakeCardinality;
+
+class EvenNumberCardinality : public CardinalityInterface {
+ public:
+ bool IsSatisfiedByCallCount(int call_count) const override {
+ return (call_count % 2) == 0;
+ }
+
+ bool IsSaturatedByCallCount(int call_count) const override {
+ return false;
+ }
+
+ void DescribeTo(std::ostream* os) const {
+ *os << "called even number of times";
+ }
+};
+
+Cardinality EvenNumber() {
+ return MakeCardinality(new EvenNumberCardinality);
+}
+
+...
+ EXPECT_CALL(foo, Bar(3))
+ .Times(EvenNumber());
+```
+
+### Writing New Actions Quickly {#QuickNewActions}
+
+If the built-in actions don't work for you, you can easily define your own one.
+Just define a functor class with a (possibly templated) call operator, matching
+the signature of your action.
+
+```cpp
+struct Increment {
+ template <typename T>
+ T operator()(T* arg) {
+ return ++(*arg);
+ }
+}
+```
+
+The same approach works with stateful functors (or any callable, really):
+
+```
+struct MultiplyBy {
+ template <typename T>
+ T operator()(T arg) { return arg * multiplier; }
+
+ int multiplier;
+}
+
+// Then use:
+// EXPECT_CALL(...).WillOnce(MultiplyBy{7});
+```
+
+#### Legacy macro-based Actions
+
+Before C++11, the functor-based actions were not supported; the old way of
+writing actions was through a set of `ACTION*` macros. We suggest to avoid them
+in new code; they hide a lot of logic behind the macro, potentially leading to
+harder-to-understand compiler errors. Nevertheless, we cover them here for
+completeness.
+
+By writing
+
+```cpp
+ACTION(name) { statements; }
+```
+
+in a namespace scope (i.e. not inside a class or function), you will define an
+action with the given name that executes the statements. The value returned by
+`statements` will be used as the return value of the action. Inside the
+statements, you can refer to the K-th (0-based) argument of the mock function as
+`argK`. For example:
+
+```cpp
+ACTION(IncrementArg1) { return ++(*arg1); }
+```
+
+allows you to write
+
+```cpp
+... WillOnce(IncrementArg1());
+```
+
+Note that you don't need to specify the types of the mock function arguments.
+Rest assured that your code is type-safe though: you'll get a compiler error if
+`*arg1` doesn't support the `++` operator, or if the type of `++(*arg1)` isn't
+compatible with the mock function's return type.
+
+Another example:
+
+```cpp
+ACTION(Foo) {
+ (*arg2)(5);
+ Blah();
+ *arg1 = 0;
+ return arg0;
+}
+```
+
+defines an action `Foo()` that invokes argument #2 (a function pointer) with 5,
+calls function `Blah()`, sets the value pointed to by argument #1 to 0, and
+returns argument #0.
+
+For more convenience and flexibility, you can also use the following pre-defined
+symbols in the body of `ACTION`:
+
+`argK_type` | The type of the K-th (0-based) argument of the mock function
+:-------------- | :-----------------------------------------------------------
+`args` | All arguments of the mock function as a tuple
+`args_type` | The type of all arguments of the mock function as a tuple
+`return_type` | The return type of the mock function
+`function_type` | The type of the mock function
+
+For example, when using an `ACTION` as a stub action for mock function:
+
+```cpp
+int DoSomething(bool flag, int* ptr);
+```
+
+we have:
+
+Pre-defined Symbol | Is Bound To
+------------------ | ---------------------------------
+`arg0` | the value of `flag`
+`arg0_type` | the type `bool`
+`arg1` | the value of `ptr`
+`arg1_type` | the type `int*`
+`args` | the tuple `(flag, ptr)`
+`args_type` | the type `std::tuple<bool, int*>`
+`return_type` | the type `int`
+`function_type` | the type `int(bool, int*)`
+
+#### Legacy macro-based parameterized Actions
+
+Sometimes you'll want to parameterize an action you define. For that we have
+another macro
+
+```cpp
+ACTION_P(name, param) { statements; }
+```
+
+For example,
+
+```cpp
+ACTION_P(Add, n) { return arg0 + n; }
+```
+
+will allow you to write
+
+```cpp
+// Returns argument #0 + 5.
+... WillOnce(Add(5));
+```
+
+For convenience, we use the term *arguments* for the values used to invoke the
+mock function, and the term *parameters* for the values used to instantiate an
+action.
+
+Note that you don't need to provide the type of the parameter either. Suppose
+the parameter is named `param`, you can also use the gMock-defined symbol
+`param_type` to refer to the type of the parameter as inferred by the compiler.
+For example, in the body of `ACTION_P(Add, n)` above, you can write `n_type` for
+the type of `n`.
+
+gMock also provides `ACTION_P2`, `ACTION_P3`, and etc to support multi-parameter
+actions. For example,
+
+```cpp
+ACTION_P2(ReturnDistanceTo, x, y) {
+ double dx = arg0 - x;
+ double dy = arg1 - y;
+ return sqrt(dx*dx + dy*dy);
+}
+```
+
+lets you write
+
+```cpp
+... WillOnce(ReturnDistanceTo(5.0, 26.5));
+```
+
+You can view `ACTION` as a degenerated parameterized action where the number of
+parameters is 0.
+
+You can also easily define actions overloaded on the number of parameters:
+
+```cpp
+ACTION_P(Plus, a) { ... }
+ACTION_P2(Plus, a, b) { ... }
+```
+
+### Restricting the Type of an Argument or Parameter in an ACTION
+
+For maximum brevity and reusability, the `ACTION*` macros don't ask you to
+provide the types of the mock function arguments and the action parameters.
+Instead, we let the compiler infer the types for us.
+
+Sometimes, however, we may want to be more explicit about the types. There are
+several tricks to do that. For example:
+
+```cpp
+ACTION(Foo) {
+ // Makes sure arg0 can be converted to int.
+ int n = arg0;
+ ... use n instead of arg0 here ...
+}
+
+ACTION_P(Bar, param) {
+ // Makes sure the type of arg1 is const char*.
+ ::testing::StaticAssertTypeEq<const char*, arg1_type>();
+
+ // Makes sure param can be converted to bool.
+ bool flag = param;
+}
+```
+
+where `StaticAssertTypeEq` is a compile-time assertion in googletest that
+verifies two types are the same.
+
+### Writing New Action Templates Quickly
+
+Sometimes you want to give an action explicit template parameters that cannot be
+inferred from its value parameters. `ACTION_TEMPLATE()` supports that and can be
+viewed as an extension to `ACTION()` and `ACTION_P*()`.
+
+The syntax:
+
+```cpp
+ACTION_TEMPLATE(ActionName,
+ HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
+ AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
+```
+
+defines an action template that takes *m* explicit template parameters and *n*
+value parameters, where *m* is in [1, 10] and *n* is in [0, 10]. `name_i` is the
+name of the *i*-th template parameter, and `kind_i` specifies whether it's a
+`typename`, an integral constant, or a template. `p_i` is the name of the *i*-th
+value parameter.
+
+Example:
+
+```cpp
+// DuplicateArg<k, T>(output) converts the k-th argument of the mock
+// function to type T and copies it to *output.
+ACTION_TEMPLATE(DuplicateArg,
+ // Note the comma between int and k:
+ HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
+ AND_1_VALUE_PARAMS(output)) {
+ *output = T(std::get<k>(args));
+}
+```
+
+To create an instance of an action template, write:
+
+```cpp
+ActionName<t1, ..., t_m>(v1, ..., v_n)
+```
+
+where the `t`s are the template arguments and the `v`s are the value arguments.
+The value argument types are inferred by the compiler. For example:
+
+```cpp
+using ::testing::_;
+...
+ int n;
+ EXPECT_CALL(mock, Foo).WillOnce(DuplicateArg<1, unsigned char>(&n));
+```
+
+If you want to explicitly specify the value argument types, you can provide
+additional template arguments:
+
+```cpp
+ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
+```
+
+where `u_i` is the desired type of `v_i`.
+
+`ACTION_TEMPLATE` and `ACTION`/`ACTION_P*` can be overloaded on the number of
+value parameters, but not on the number of template parameters. Without the
+restriction, the meaning of the following is unclear:
+
+```cpp
+ OverloadedAction<int, bool>(x);
+```
+
+Are we using a single-template-parameter action where `bool` refers to the type
+of `x`, or a two-template-parameter action where the compiler is asked to infer
+the type of `x`?
+
+### Using the ACTION Object's Type
+
+If you are writing a function that returns an `ACTION` object, you'll need to
+know its type. The type depends on the macro used to define the action and the
+parameter types. The rule is relatively simple:
+
+
+| Given Definition | Expression | Has Type |
+| ----------------------------- | ------------------- | --------------------- |
+| `ACTION(Foo)` | `Foo()` | `FooAction` |
+| `ACTION_TEMPLATE(Foo, HAS_m_TEMPLATE_PARAMS(...), AND_0_VALUE_PARAMS())` | `Foo<t1, ..., t_m>()` | `FooAction<t1, ..., t_m>` |
+| `ACTION_P(Bar, param)` | `Bar(int_value)` | `BarActionP<int>` |
+| `ACTION_TEMPLATE(Bar, HAS_m_TEMPLATE_PARAMS(...), AND_1_VALUE_PARAMS(p1))` | `Bar<t1, ..., t_m>(int_value)` | `BarActionP<t1, ..., t_m, int>` |
+| `ACTION_P2(Baz, p1, p2)` | `Baz(bool_value, int_value)` | `BazActionP2<bool, int>` |
+| `ACTION_TEMPLATE(Baz, HAS_m_TEMPLATE_PARAMS(...), AND_2_VALUE_PARAMS(p1, p2))` | `Baz<t1, ..., t_m>(bool_value, int_value)` | `BazActionP2<t1, ..., t_m, bool, int>` |
+| ... | ... | ... |
+
+
+Note that we have to pick different suffixes (`Action`, `ActionP`, `ActionP2`,
+and etc) for actions with different numbers of value parameters, or the action
+definitions cannot be overloaded on the number of them.
+
+### Writing New Monomorphic Actions {#NewMonoActions}
+
+While the `ACTION*` macros are very convenient, sometimes they are
+inappropriate. For example, despite the tricks shown in the previous recipes,
+they don't let you directly specify the types of the mock function arguments and
+the action parameters, which in general leads to unoptimized compiler error
+messages that can baffle unfamiliar users. They also don't allow overloading
+actions based on parameter types without jumping through some hoops.
+
+An alternative to the `ACTION*` macros is to implement
+`::testing::ActionInterface<F>`, where `F` is the type of the mock function in
+which the action will be used. For example:
+
+```cpp
+template <typename F>
+class ActionInterface {
+ public:
+ virtual ~ActionInterface();
+
+ // Performs the action. Result is the return type of function type
+ // F, and ArgumentTuple is the tuple of arguments of F.
+ //
+
+ // For example, if F is int(bool, const string&), then Result would
+ // be int, and ArgumentTuple would be std::tuple<bool, const string&>.
+ virtual Result Perform(const ArgumentTuple& args) = 0;
+};
+```
+
+```cpp
+using ::testing::_;
+using ::testing::Action;
+using ::testing::ActionInterface;
+using ::testing::MakeAction;
+
+typedef int IncrementMethod(int*);
+
+class IncrementArgumentAction : public ActionInterface<IncrementMethod> {
+ public:
+ int Perform(const std::tuple<int*>& args) override {
+ int* p = std::get<0>(args); // Grabs the first argument.
+ return *p++;
+ }
+};
+
+Action<IncrementMethod> IncrementArgument() {
+ return MakeAction(new IncrementArgumentAction);
+}
+
+...
+ EXPECT_CALL(foo, Baz(_))
+ .WillOnce(IncrementArgument());
+
+ int n = 5;
+ foo.Baz(&n); // Should return 5 and change n to 6.
+```
+
+### Writing New Polymorphic Actions {#NewPolyActions}
+
+The previous recipe showed you how to define your own action. This is all good,
+except that you need to know the type of the function in which the action will
+be used. Sometimes that can be a problem. For example, if you want to use the
+action in functions with *different* types (e.g. like `Return()` and
+`SetArgPointee()`).
+
+If an action can be used in several types of mock functions, we say it's
+*polymorphic*. The `MakePolymorphicAction()` function template makes it easy to
+define such an action:
+
+```cpp
+namespace testing {
+template <typename Impl>
+PolymorphicAction<Impl> MakePolymorphicAction(const Impl& impl);
+} // namespace testing
+```
+
+As an example, let's define an action that returns the second argument in the
+mock function's argument list. The first step is to define an implementation
+class:
+
+```cpp
+class ReturnSecondArgumentAction {
+ public:
+ template <typename Result, typename ArgumentTuple>
+ Result Perform(const ArgumentTuple& args) const {
+ // To get the i-th (0-based) argument, use std::get(args).
+ return std::get<1>(args);
+ }
+};
+```
+
+This implementation class does *not* need to inherit from any particular class.
+What matters is that it must have a `Perform()` method template. This method
+template takes the mock function's arguments as a tuple in a **single**
+argument, and returns the result of the action. It can be either `const` or not,
+but must be invocable with exactly one template argument, which is the result
+type. In other words, you must be able to call `Perform<R>(args)` where `R` is
+the mock function's return type and `args` is its arguments in a tuple.
+
+Next, we use `MakePolymorphicAction()` to turn an instance of the implementation
+class into the polymorphic action we need. It will be convenient to have a
+wrapper for this:
+
+```cpp
+using ::testing::MakePolymorphicAction;
+using ::testing::PolymorphicAction;
+
+PolymorphicAction<ReturnSecondArgumentAction> ReturnSecondArgument() {
+ return MakePolymorphicAction(ReturnSecondArgumentAction());
+}
+```
+
+Now, you can use this polymorphic action the same way you use the built-in ones:
+
+```cpp
+using ::testing::_;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(int, DoThis, (bool flag, int n), (override));
+ MOCK_METHOD(string, DoThat, (int x, const char* str1, const char* str2),
+ (override));
+};
+
+ ...
+ MockFoo foo;
+ EXPECT_CALL(foo, DoThis).WillOnce(ReturnSecondArgument());
+ EXPECT_CALL(foo, DoThat).WillOnce(ReturnSecondArgument());
+ ...
+ foo.DoThis(true, 5); // Will return 5.
+ foo.DoThat(1, "Hi", "Bye"); // Will return "Hi".
+```
+
+### Teaching gMock How to Print Your Values
+
+When an uninteresting or unexpected call occurs, gMock prints the argument
+values and the stack trace to help you debug. Assertion macros like
+`EXPECT_THAT` and `EXPECT_EQ` also print the values in question when the
+assertion fails. gMock and googletest do this using googletest's user-extensible
+value printer.
+
+This printer knows how to print built-in C++ types, native arrays, STL
+containers, and any type that supports the `<<` operator. For other types, it
+prints the raw bytes in the value and hopes that you the user can figure it out.
+[The GoogleTest advanced guide](advanced.md#teaching-googletest-how-to-print-your-values)
+explains how to extend the printer to do a better job at printing your
+particular type than to dump the bytes.
+
+## Useful Mocks Created Using gMock
+
+<!--#include file="includes/g3_testing_LOGs.md"-->
+<!--#include file="includes/g3_mock_callbacks.md"-->
+
+### Mock std::function {#MockFunction}
+
+`std::function` is a general function type introduced in C++11. It is a
+preferred way of passing callbacks to new interfaces. Functions are copiable,
+and are not usually passed around by pointer, which makes them tricky to mock.
+But fear not - `MockFunction` can help you with that.
+
+`MockFunction<R(T1, ..., Tn)>` has a mock method `Call()` with the signature:
+
+```cpp
+ R Call(T1, ..., Tn);
+```
+
+It also has a `AsStdFunction()` method, which creates a `std::function` proxy
+forwarding to Call:
+
+```cpp
+ std::function<R(T1, ..., Tn)> AsStdFunction();
+```
+
+To use `MockFunction`, first create `MockFunction` object and set up
+expectations on its `Call` method. Then pass proxy obtained from
+`AsStdFunction()` to the code you are testing. For example:
+
+```cpp
+TEST(FooTest, RunsCallbackWithBarArgument) {
+ // 1. Create a mock object.
+ MockFunction<int(string)> mock_function;
+
+ // 2. Set expectations on Call() method.
+ EXPECT_CALL(mock_function, Call("bar")).WillOnce(Return(1));
+
+ // 3. Exercise code that uses std::function.
+ Foo(mock_function.AsStdFunction());
+ // Foo's signature can be either of:
+ // void Foo(const std::function<int(string)>& fun);
+ // void Foo(std::function<int(string)> fun);
+
+ // 4. All expectations will be verified when mock_function
+ // goes out of scope and is destroyed.
+}
+```
+
+Remember that function objects created with `AsStdFunction()` are just
+forwarders. If you create multiple of them, they will share the same set of
+expectations.
+
+Although `std::function` supports unlimited number of arguments, `MockFunction`
+implementation is limited to ten. If you ever hit that limit... well, your
+callback has bigger problems than being mockable. :-)

+# Legacy gMock FAQ
+
+### When I call a method on my mock object, the method for the real object is invoked instead. What's the problem?
+
+In order for a method to be mocked, it must be *virtual*, unless you use the
+[high-perf dependency injection technique](gmock_cook_book.md#MockingNonVirtualMethods).
+
+### Can I mock a variadic function?
+
+You cannot mock a variadic function (i.e. a function taking ellipsis (`...`)
+arguments) directly in gMock.
+
+The problem is that in general, there is *no way* for a mock object to know how
+many arguments are passed to the variadic method, and what the arguments' types
+are. Only the *author of the base class* knows the protocol, and we cannot look
+into his or her head.
+
+Therefore, to mock such a function, the *user* must teach the mock object how to
+figure out the number of arguments and their types. One way to do it is to
+provide overloaded versions of the function.
+
+Ellipsis arguments are inherited from C and not really a C++ feature. They are
+unsafe to use and don't work with arguments that have constructors or
+destructors. Therefore we recommend to avoid them in C++ as much as possible.
+
+### MSVC gives me warning C4301 or C4373 when I define a mock method with a const parameter. Why?
+
+If you compile this using Microsoft Visual C++ 2005 SP1:
+
+```cpp
+class Foo {
+ ...
+ virtual void Bar(const int i) = 0;
+};
+
+class MockFoo : public Foo {
+ ...
+ MOCK_METHOD(void, Bar, (const int i), (override));
+};
+```
+
+You may get the following warning:
+
+```shell
+warning C4301: 'MockFoo::Bar': overriding virtual function only differs from 'Foo::Bar' by const/volatile qualifier
+```
+
+This is a MSVC bug. The same code compiles fine with gcc, for example. If you
+use Visual C++ 2008 SP1, you would get the warning:
+
+```shell
+warning C4373: 'MockFoo::Bar': virtual function overrides 'Foo::Bar', previous versions of the compiler did not override when parameters only differed by const/volatile qualifiers
+```
+
+In C++, if you *declare* a function with a `const` parameter, the `const`
+modifier is ignored. Therefore, the `Foo` base class above is equivalent to:
+
+```cpp
+class Foo {
+ ...
+ virtual void Bar(int i) = 0; // int or const int? Makes no difference.
+};
+```
+
+In fact, you can *declare* `Bar()` with an `int` parameter, and define it with a
+`const int` parameter. The compiler will still match them up.
+
+Since making a parameter `const` is meaningless in the method declaration, we
+recommend to remove it in both `Foo` and `MockFoo`. That should workaround the
+VC bug.
+
+Note that we are talking about the *top-level* `const` modifier here. If the
+function parameter is passed by pointer or reference, declaring the pointee or
+referee as `const` is still meaningful. For example, the following two
+declarations are *not* equivalent:
+
+```cpp
+void Bar(int* p); // Neither p nor *p is const.
+void Bar(const int* p); // p is not const, but *p is.
+```
+
+### I can't figure out why gMock thinks my expectations are not satisfied. What should I do?
+
+You might want to run your test with `--gmock_verbose=info`. This flag lets
+gMock print a trace of every mock function call it receives. By studying the
+trace, you'll gain insights on why the expectations you set are not met.
+
+If you see the message "The mock function has no default action set, and its
+return type has no default value set.", then try
+[adding a default action](gmock_cheat_sheet.md#OnCall). Due to a known issue,
+unexpected calls on mocks without default actions don't print out a detailed
+comparison between the actual arguments and the expected arguments.
+
+### My program crashed and `ScopedMockLog` spit out tons of messages. Is it a gMock bug?
+
+gMock and `ScopedMockLog` are likely doing the right thing here.
+
+When a test crashes, the failure signal handler will try to log a lot of
+information (the stack trace, and the address map, for example). The messages
+are compounded if you have many threads with depth stacks. When `ScopedMockLog`
+intercepts these messages and finds that they don't match any expectations, it
+prints an error for each of them.
+
+You can learn to ignore the errors, or you can rewrite your expectations to make
+your test more robust, for example, by adding something like:
+
+```cpp
+using ::testing::AnyNumber;
+using ::testing::Not;
+...
+ // Ignores any log not done by us.
+ EXPECT_CALL(log, Log(_, Not(EndsWith("/my_file.cc")), _))
+ .Times(AnyNumber());
+```
+
+### How can I assert that a function is NEVER called?
+
+```cpp
+using ::testing::_;
+...
+ EXPECT_CALL(foo, Bar(_))
+ .Times(0);
+```
+
+### I have a failed test where gMock tells me TWICE that a particular expectation is not satisfied. Isn't this redundant?
+
+When gMock detects a failure, it prints relevant information (the mock function
+arguments, the state of relevant expectations, and etc) to help the user debug.
+If another failure is detected, gMock will do the same, including printing the
+state of relevant expectations.
+
+Sometimes an expectation's state didn't change between two failures, and you'll
+see the same description of the state twice. They are however *not* redundant,
+as they refer to *different points in time*. The fact they are the same *is*
+interesting information.
+
+### I get a heapcheck failure when using a mock object, but using a real object is fine. What can be wrong?
+
+Does the class (hopefully a pure interface) you are mocking have a virtual
+destructor?
+
+Whenever you derive from a base class, make sure its destructor is virtual.
+Otherwise Bad Things will happen. Consider the following code:
+
+```cpp
+class Base {
+ public:
+ // Not virtual, but should be.
+ ~Base() { ... }
+ ...
+};
+
+class Derived : public Base {
+ public:
+ ...
+ private:
+ std::string value_;
+};
+
+...
+ Base* p = new Derived;
+ ...
+ delete p; // Surprise! ~Base() will be called, but ~Derived() will not
+ // - value_ is leaked.
+```
+
+By changing `~Base()` to virtual, `~Derived()` will be correctly called when
+`delete p` is executed, and the heap checker will be happy.
+
+### The "newer expectations override older ones" rule makes writing expectations awkward. Why does gMock do that?
+
+When people complain about this, often they are referring to code like:
+
+```cpp
+using ::testing::Return;
+...
+ // foo.Bar() should be called twice, return 1 the first time, and return
+ // 2 the second time. However, I have to write the expectations in the
+ // reverse order. This sucks big time!!!
+ EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(2))
+ .RetiresOnSaturation();
+ EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(1))
+ .RetiresOnSaturation();
+```
+
+The problem, is that they didn't pick the **best** way to express the test's
+intent.
+
+By default, expectations don't have to be matched in *any* particular order. If
+you want them to match in a certain order, you need to be explicit. This is
+gMock's (and jMock's) fundamental philosophy: it's easy to accidentally
+over-specify your tests, and we want to make it harder to do so.
+
+There are two better ways to write the test spec. You could either put the
+expectations in sequence:
+
+```cpp
+using ::testing::Return;
+...
+ // foo.Bar() should be called twice, return 1 the first time, and return
+ // 2 the second time. Using a sequence, we can write the expectations
+ // in their natural order.
+ {
+ InSequence s;
+ EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(1))
+ .RetiresOnSaturation();
+ EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(2))
+ .RetiresOnSaturation();
+ }
+```
+
+or you can put the sequence of actions in the same expectation:
+
+```cpp
+using ::testing::Return;
+...
+ // foo.Bar() should be called twice, return 1 the first time, and return
+ // 2 the second time.
+ EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(1))
+ .WillOnce(Return(2))
+ .RetiresOnSaturation();
+```
+
+Back to the original questions: why does gMock search the expectations (and
+`ON_CALL`s) from back to front? Because this allows a user to set up a mock's
+behavior for the common case early (e.g. in the mock's constructor or the test
+fixture's set-up phase) and customize it with more specific rules later. If
+gMock searches from front to back, this very useful pattern won't be possible.
+
+### gMock prints a warning when a function without EXPECT_CALL is called, even if I have set its behavior using ON_CALL. Would it be reasonable not to show the warning in this case?
+
+When choosing between being neat and being safe, we lean toward the latter. So
+the answer is that we think it's better to show the warning.
+
+Often people write `ON_CALL`s in the mock object's constructor or `SetUp()`, as
+the default behavior rarely changes from test to test. Then in the test body
+they set the expectations, which are often different for each test. Having an
+`ON_CALL` in the set-up part of a test doesn't mean that the calls are expected.
+If there's no `EXPECT_CALL` and the method is called, it's possibly an error. If
+we quietly let the call go through without notifying the user, bugs may creep in
+unnoticed.
+
+If, however, you are sure that the calls are OK, you can write
+
+```cpp
+using ::testing::_;
+...
+ EXPECT_CALL(foo, Bar(_))
+ .WillRepeatedly(...);
+```
+
+instead of
+
+```cpp
+using ::testing::_;
+...
+ ON_CALL(foo, Bar(_))
+ .WillByDefault(...);
+```
+
+This tells gMock that you do expect the calls and no warning should be printed.
+
+Also, you can control the verbosity by specifying `--gmock_verbose=error`. Other
+values are `info` and `warning`. If you find the output too noisy when
+debugging, just choose a less verbose level.
+
+### How can I delete the mock function's argument in an action?
+
+If your mock function takes a pointer argument and you want to delete that
+argument, you can use testing::DeleteArg<N>() to delete the N'th (zero-indexed)
+argument:
+
+```cpp
+using ::testing::_;
+ ...
+ MOCK_METHOD(void, Bar, (X* x, const Y& y));
+ ...
+ EXPECT_CALL(mock_foo_, Bar(_, _))
+ .WillOnce(testing::DeleteArg<0>()));
+```
+
+### How can I perform an arbitrary action on a mock function's argument?
+
+If you find yourself needing to perform some action that's not supported by
+gMock directly, remember that you can define your own actions using
+[`MakeAction()`](#NewMonoActions) or
+[`MakePolymorphicAction()`](#NewPolyActions), or you can write a stub function
+and invoke it using [`Invoke()`](#FunctionsAsActions).
+
+```cpp
+using ::testing::_;
+using ::testing::Invoke;
+ ...
+ MOCK_METHOD(void, Bar, (X* p));
+ ...
+ EXPECT_CALL(mock_foo_, Bar(_))
+ .WillOnce(Invoke(MyAction(...)));
+```
+
+### My code calls a static/global function. Can I mock it?
+
+You can, but you need to make some changes.
+
+In general, if you find yourself needing to mock a static function, it's a sign
+that your modules are too tightly coupled (and less flexible, less reusable,
+less testable, etc). You are probably better off defining a small interface and
+call the function through that interface, which then can be easily mocked. It's
+a bit of work initially, but usually pays for itself quickly.
+
+This Google Testing Blog
+[post](https://testing.googleblog.com/2008/06/defeat-static-cling.html) says it
+excellently. Check it out.
+
+### My mock object needs to do complex stuff. It's a lot of pain to specify the actions. gMock sucks!
+
+I know it's not a question, but you get an answer for free any way. :-)
+
+With gMock, you can create mocks in C++ easily. And people might be tempted to
+use them everywhere. Sometimes they work great, and sometimes you may find them,
+well, a pain to use. So, what's wrong in the latter case?
+
+When you write a test without using mocks, you exercise the code and assert that
+it returns the correct value or that the system is in an expected state. This is
+sometimes called "state-based testing".
+
+Mocks are great for what some call "interaction-based" testing: instead of
+checking the system state at the very end, mock objects verify that they are
+invoked the right way and report an error as soon as it arises, giving you a
+handle on the precise context in which the error was triggered. This is often
+more effective and economical to do than state-based testing.
+
+If you are doing state-based testing and using a test double just to simulate
+the real object, you are probably better off using a fake. Using a mock in this
+case causes pain, as it's not a strong point for mocks to perform complex
+actions. If you experience this and think that mocks suck, you are just not
+using the right tool for your problem. Or, you might be trying to solve the
+wrong problem. :-)
+
+### I got a warning "Uninteresting function call encountered - default action taken.." Should I panic?
+
+By all means, NO! It's just an FYI. :-)
+
+What it means is that you have a mock function, you haven't set any expectations
+on it (by gMock's rule this means that you are not interested in calls to this
+function and therefore it can be called any number of times), and it is called.
+That's OK - you didn't say it's not OK to call the function!
+
+What if you actually meant to disallow this function to be called, but forgot to
+write `EXPECT_CALL(foo, Bar()).Times(0)`? While one can argue that it's the
+user's fault, gMock tries to be nice and prints you a note.
+
+So, when you see the message and believe that there shouldn't be any
+uninteresting calls, you should investigate what's going on. To make your life
+easier, gMock dumps the stack trace when an uninteresting call is encountered.
+From that you can figure out which mock function it is, and how it is called.
+
+### I want to define a custom action. Should I use Invoke() or implement the ActionInterface interface?
+
+Either way is fine - you want to choose the one that's more convenient for your
+circumstance.
+
+Usually, if your action is for a particular function type, defining it using
+`Invoke()` should be easier; if your action can be used in functions of
+different types (e.g. if you are defining `Return(*value*)`),
+`MakePolymorphicAction()` is easiest. Sometimes you want precise control on what
+types of functions the action can be used in, and implementing `ActionInterface`
+is the way to go here. See the implementation of `Return()` in `gmock-actions.h`
+for an example.
+
+### I use SetArgPointee() in WillOnce(), but gcc complains about "conflicting return type specified". What does it mean?
+
+You got this error as gMock has no idea what value it should return when the
+mock method is called. `SetArgPointee()` says what the side effect is, but
+doesn't say what the return value should be. You need `DoAll()` to chain a
+`SetArgPointee()` with a `Return()` that provides a value appropriate to the API
+being mocked.
+
+See this [recipe](gmock_cook_book.md#mocking-side-effects) for more details and
+an example.
+
+### I have a huge mock class, and Microsoft Visual C++ runs out of memory when compiling it. What can I do?
+
+We've noticed that when the `/clr` compiler flag is used, Visual C++ uses 5~6
+times as much memory when compiling a mock class. We suggest to avoid `/clr`
+when compiling native C++ mocks.

+# gMock for Dummies
+
+## What Is gMock?
+
+When you write a prototype or test, often it's not feasible or wise to rely on
+real objects entirely. A **mock object** implements the same interface as a real
+object (so it can be used as one), but lets you specify at run time how it will
+be used and what it should do (which methods will be called? in which order? how
+many times? with what arguments? what will they return? etc).
+
+It is easy to confuse the term *fake objects* with mock objects. Fakes and mocks
+actually mean very different things in the Test-Driven Development (TDD)
+community:
+
+* **Fake** objects have working implementations, but usually take some
+ shortcut (perhaps to make the operations less expensive), which makes them
+ not suitable for production. An in-memory file system would be an example of
+ a fake.
+* **Mocks** are objects pre-programmed with *expectations*, which form a
+ specification of the calls they are expected to receive.
+
+If all this seems too abstract for you, don't worry - the most important thing
+to remember is that a mock allows you to check the *interaction* between itself
+and code that uses it. The difference between fakes and mocks shall become much
+clearer once you start to use mocks.
+
+**gMock** is a library (sometimes we also call it a "framework" to make it sound
+cool) for creating mock classes and using them. It does to C++ what
+jMock/EasyMock does to Java (well, more or less).
+
+When using gMock,
+
+1. first, you use some simple macros to describe the interface you want to
+ mock, and they will expand to the implementation of your mock class;
+2. next, you create some mock objects and specify its expectations and behavior
+ using an intuitive syntax;
+3. then you exercise code that uses the mock objects. gMock will catch any
+ violation to the expectations as soon as it arises.
+
+## Why gMock?
+
+While mock objects help you remove unnecessary dependencies in tests and make
+them fast and reliable, using mocks manually in C++ is *hard*:
+
+* Someone has to implement the mocks. The job is usually tedious and
+ error-prone. No wonder people go great distance to avoid it.
+* The quality of those manually written mocks is a bit, uh, unpredictable. You
+ may see some really polished ones, but you may also see some that were
+ hacked up in a hurry and have all sorts of ad hoc restrictions.
+* The knowledge you gained from using one mock doesn't transfer to the next
+ one.
+
+In contrast, Java and Python programmers have some fine mock frameworks (jMock,
+EasyMock, etc), which automate the creation of mocks. As a result, mocking is a
+proven effective technique and widely adopted practice in those communities.
+Having the right tool absolutely makes the difference.
+
+gMock was built to help C++ programmers. It was inspired by jMock and EasyMock,
+but designed with C++'s specifics in mind. It is your friend if any of the
+following problems is bothering you:
+
+* You are stuck with a sub-optimal design and wish you had done more
+ prototyping before it was too late, but prototyping in C++ is by no means
+ "rapid".
+* Your tests are slow as they depend on too many libraries or use expensive
+ resources (e.g. a database).
+* Your tests are brittle as some resources they use are unreliable (e.g. the
+ network).
+* You want to test how your code handles a failure (e.g. a file checksum
+ error), but it's not easy to cause one.
+* You need to make sure that your module interacts with other modules in the
+ right way, but it's hard to observe the interaction; therefore you resort to
+ observing the side effects at the end of the action, but it's awkward at
+ best.
+* You want to "mock out" your dependencies, except that they don't have mock
+ implementations yet; and, frankly, you aren't thrilled by some of those
+ hand-written mocks.
+
+We encourage you to use gMock as
+
+* a *design* tool, for it lets you experiment with your interface design early
+ and often. More iterations lead to better designs!
+* a *testing* tool to cut your tests' outbound dependencies and probe the
+ interaction between your module and its collaborators.
+
+## Getting Started
+
+gMock is bundled with googletest.
+
+## A Case for Mock Turtles
+
+Let's look at an example. Suppose you are developing a graphics program that
+relies on a [LOGO](http://en.wikipedia.org/wiki/Logo_programming_language)-like
+API for drawing. How would you test that it does the right thing? Well, you can
+run it and compare the screen with a golden screen snapshot, but let's admit it:
+tests like this are expensive to run and fragile (What if you just upgraded to a
+shiny new graphics card that has better anti-aliasing? Suddenly you have to
+update all your golden images.). It would be too painful if all your tests are
+like this. Fortunately, you learned about
+[Dependency Injection](http://en.wikipedia.org/wiki/Dependency_injection) and know the right thing
+to do: instead of having your application talk to the system API directly, wrap
+the API in an interface (say, `Turtle`) and code to that interface:
+
+```cpp
+class Turtle {
+ ...
+ virtual ~Turtle() {}
+ virtual void PenUp() = 0;
+ virtual void PenDown() = 0;
+ virtual void Forward(int distance) = 0;
+ virtual void Turn(int degrees) = 0;
+ virtual void GoTo(int x, int y) = 0;
+ virtual int GetX() const = 0;
+ virtual int GetY() const = 0;
+};
+```
+
+(Note that the destructor of `Turtle` **must** be virtual, as is the case for
+**all** classes you intend to inherit from - otherwise the destructor of the
+derived class will not be called when you delete an object through a base
+pointer, and you'll get corrupted program states like memory leaks.)
+
+You can control whether the turtle's movement will leave a trace using `PenUp()`
+and `PenDown()`, and control its movement using `Forward()`, `Turn()`, and
+`GoTo()`. Finally, `GetX()` and `GetY()` tell you the current position of the
+turtle.
+
+Your program will normally use a real implementation of this interface. In
+tests, you can use a mock implementation instead. This allows you to easily
+check what drawing primitives your program is calling, with what arguments, and
+in which order. Tests written this way are much more robust (they won't break
+because your new machine does anti-aliasing differently), easier to read and
+maintain (the intent of a test is expressed in the code, not in some binary
+images), and run *much, much faster*.
+
+## Writing the Mock Class
+
+If you are lucky, the mocks you need to use have already been implemented by
+some nice people. If, however, you find yourself in the position to write a mock
+class, relax - gMock turns this task into a fun game! (Well, almost.)
+
+### How to Define It
+
+Using the `Turtle` interface as example, here are the simple steps you need to
+follow:
+
+* Derive a class `MockTurtle` from `Turtle`.
+* Take a *virtual* function of `Turtle` (while it's possible to
+ [mock non-virtual methods using templates](gmock_cook_book.md#MockingNonVirtualMethods),
+ it's much more involved).
+* In the `public:` section of the child class, write `MOCK_METHOD();`
+* Now comes the fun part: you take the function signature, cut-and-paste it
+ into the macro, and add two commas - one between the return type and the
+ name, another between the name and the argument list.
+* If you're mocking a const method, add a 4th parameter containing `(const)`
+ (the parentheses are required).
+* Since you're overriding a virtual method, we suggest adding the `override`
+ keyword. For const methods the 4th parameter becomes `(const, override)`,
+ for non-const methods just `(override)`. This isn't mandatory.
+* Repeat until all virtual functions you want to mock are done. (It goes
+ without saying that *all* pure virtual methods in your abstract class must
+ be either mocked or overridden.)
+
+After the process, you should have something like:
+
+```cpp
+#include "gmock/gmock.h" // Brings in gMock.
+
+class MockTurtle : public Turtle {
+ public:
+ ...
+ MOCK_METHOD(void, PenUp, (), (override));
+ MOCK_METHOD(void, PenDown, (), (override));
+ MOCK_METHOD(void, Forward, (int distance), (override));
+ MOCK_METHOD(void, Turn, (int degrees), (override));
+ MOCK_METHOD(void, GoTo, (int x, int y), (override));
+ MOCK_METHOD(int, GetX, (), (const, override));
+ MOCK_METHOD(int, GetY, (), (const, override));
+};
+```
+
+You don't need to define these mock methods somewhere else - the `MOCK_METHOD`
+macro will generate the definitions for you. It's that simple!
+
+### Where to Put It
+
+When you define a mock class, you need to decide where to put its definition.
+Some people put it in a `_test.cc`. This is fine when the interface being mocked
+(say, `Foo`) is owned by the same person or team. Otherwise, when the owner of
+`Foo` changes it, your test could break. (You can't really expect `Foo`'s
+maintainer to fix every test that uses `Foo`, can you?)
+
+Generally, you should not define mock classes you don't own. If you must mock
+such a class owned by others, define the mock class in `Foo`'s Bazel package
+(usually the same directory or a `testing` sub-directory), and put it in a `.h`
+and a `cc_library` with `testonly=True`. Then everyone can reference them from
+their tests. If `Foo` ever changes, there is only one copy of `MockFoo` to
+change, and only tests that depend on the changed methods need to be fixed.
+
+Another way to do it: you can introduce a thin layer `FooAdaptor` on top of
+`Foo` and code to this new interface. Since you own `FooAdaptor`, you can absorb
+changes in `Foo` much more easily. While this is more work initially, carefully
+choosing the adaptor interface can make your code easier to write and more
+readable (a net win in the long run), as you can choose `FooAdaptor` to fit your
+specific domain much better than `Foo` does.
+
+## Using Mocks in Tests
+
+Once you have a mock class, using it is easy. The typical work flow is:
+
+1. Import the gMock names from the `testing` namespace such that you can use
+ them unqualified (You only have to do it once per file). Remember that
+ namespaces are a good idea.
+2. Create some mock objects.
+3. Specify your expectations on them (How many times will a method be called?
+ With what arguments? What should it do? etc.).
+4. Exercise some code that uses the mocks; optionally, check the result using
+ googletest assertions. If a mock method is called more than expected or with
+ wrong arguments, you'll get an error immediately.
+5. When a mock is destructed, gMock will automatically check whether all
+ expectations on it have been satisfied.
+
+Here's an example:
+
+```cpp
+#include "path/to/mock-turtle.h"
+#include "gmock/gmock.h"
+#include "gtest/gtest.h"
+
+using ::testing::AtLeast; // #1
+
+TEST(PainterTest, CanDrawSomething) {
+ MockTurtle turtle; // #2
+ EXPECT_CALL(turtle, PenDown()) // #3
+ .Times(AtLeast(1));
+
+ Painter painter(&turtle); // #4
+
+ EXPECT_TRUE(painter.DrawCircle(0, 0, 10)); // #5
+}
+```
+
+As you might have guessed, this test checks that `PenDown()` is called at least
+once. If the `painter` object didn't call this method, your test will fail with
+a message like this:
+
+```text
+path/to/my_test.cc:119: Failure
+Actual function call count doesn't match this expectation:
+Actually: never called;
+Expected: called at least once.
+Stack trace:
+...
+```
+
+**Tip 1:** If you run the test from an Emacs buffer, you can hit `<Enter>` on
+the line number to jump right to the failed expectation.
+
+**Tip 2:** If your mock objects are never deleted, the final verification won't
+happen. Therefore it's a good idea to turn on the heap checker in your tests
+when you allocate mocks on the heap. You get that automatically if you use the
+`gtest_main` library already.
+
+**Important note:** gMock requires expectations to be set **before** the mock
+functions are called, otherwise the behavior is **undefined**. Do not alternate
+between calls to `EXPECT_CALL()` and calls to the mock functions, and do not set
+any expectations on a mock after passing the mock to an API.
+
+This means `EXPECT_CALL()` should be read as expecting that a call will occur
+*in the future*, not that a call has occurred. Why does gMock work like that?
+Well, specifying the expectation beforehand allows gMock to report a violation
+as soon as it rises, when the context (stack trace, etc) is still available.
+This makes debugging much easier.
+
+Admittedly, this test is contrived and doesn't do much. You can easily achieve
+the same effect without using gMock. However, as we shall reveal soon, gMock
+allows you to do *so much more* with the mocks.
+
+## Setting Expectations
+
+The key to using a mock object successfully is to set the *right expectations*
+on it. If you set the expectations too strict, your test will fail as the result
+of unrelated changes. If you set them too loose, bugs can slip through. You want
+to do it just right such that your test can catch exactly the kind of bugs you
+intend it to catch. gMock provides the necessary means for you to do it "just
+right."
+
+### General Syntax
+
+In gMock we use the `EXPECT_CALL()` macro to set an expectation on a mock
+method. The general syntax is:
+
+```cpp
+EXPECT_CALL(mock_object, method(matchers))
+ .Times(cardinality)
+ .WillOnce(action)
+ .WillRepeatedly(action);
+```
+
+The macro has two arguments: first the mock object, and then the method and its
+arguments. Note that the two are separated by a comma (`,`), not a period (`.`).
+(Why using a comma? The answer is that it was necessary for technical reasons.)
+If the method is not overloaded, the macro can also be called without matchers:
+
+```cpp
+EXPECT_CALL(mock_object, non-overloaded-method)
+ .Times(cardinality)
+ .WillOnce(action)
+ .WillRepeatedly(action);
+```
+
+This syntax allows the test writer to specify "called with any arguments"
+without explicitly specifying the number or types of arguments. To avoid
+unintended ambiguity, this syntax may only be used for methods that are not
+overloaded.
+
+Either form of the macro can be followed by some optional *clauses* that provide
+more information about the expectation. We'll discuss how each clause works in
+the coming sections.
+
+This syntax is designed to make an expectation read like English. For example,
+you can probably guess that
+
+```cpp
+using ::testing::Return;
+...
+EXPECT_CALL(turtle, GetX())
+ .Times(5)
+ .WillOnce(Return(100))
+ .WillOnce(Return(150))
+ .WillRepeatedly(Return(200));
+```
+
+says that the `turtle` object's `GetX()` method will be called five times, it
+will return 100 the first time, 150 the second time, and then 200 every time.
+Some people like to call this style of syntax a Domain-Specific Language (DSL).
+
+{: .callout .note}
+**Note:** Why do we use a macro to do this? Well it serves two purposes: first
+it makes expectations easily identifiable (either by `grep` or by a human
+reader), and second it allows gMock to include the source file location of a
+failed expectation in messages, making debugging easier.
+
+### Matchers: What Arguments Do We Expect?
+
+When a mock function takes arguments, we may specify what arguments we are
+expecting, for example:
+
+```cpp
+// Expects the turtle to move forward by 100 units.
+EXPECT_CALL(turtle, Forward(100));
+```
+
+Oftentimes you do not want to be too specific. Remember that talk about tests
+being too rigid? Over specification leads to brittle tests and obscures the
+intent of tests. Therefore we encourage you to specify only what's necessary—no
+more, no less. If you aren't interested in the value of an argument, write `_`
+as the argument, which means "anything goes":
+
+```cpp
+using ::testing::_;
+...
+// Expects that the turtle jumps to somewhere on the x=50 line.
+EXPECT_CALL(turtle, GoTo(50, _));
+```
+
+`_` is an instance of what we call **matchers**. A matcher is like a predicate
+and can test whether an argument is what we'd expect. You can use a matcher
+inside `EXPECT_CALL()` wherever a function argument is expected. `_` is a
+convenient way of saying "any value".
+
+In the above examples, `100` and `50` are also matchers; implicitly, they are
+the same as `Eq(100)` and `Eq(50)`, which specify that the argument must be
+equal (using `operator==`) to the matcher argument. There are many
+[built-in matchers](reference/matchers.md) for common types (as well as
+[custom matchers](gmock_cook_book.md#NewMatchers)); for example:
+
+```cpp
+using ::testing::Ge;
+...
+// Expects the turtle moves forward by at least 100.
+EXPECT_CALL(turtle, Forward(Ge(100)));
+```
+
+If you don't care about *any* arguments, rather than specify `_` for each of
+them you may instead omit the parameter list:
+
+```cpp
+// Expects the turtle to move forward.
+EXPECT_CALL(turtle, Forward);
+// Expects the turtle to jump somewhere.
+EXPECT_CALL(turtle, GoTo);
+```
+
+This works for all non-overloaded methods; if a method is overloaded, you need
+to help gMock resolve which overload is expected by specifying the number of
+arguments and possibly also the
+[types of the arguments](gmock_cook_book.md#SelectOverload).
+
+### Cardinalities: How Many Times Will It Be Called?
+
+The first clause we can specify following an `EXPECT_CALL()` is `Times()`. We
+call its argument a **cardinality** as it tells *how many times* the call should
+occur. It allows us to repeat an expectation many times without actually writing
+it as many times. More importantly, a cardinality can be "fuzzy", just like a
+matcher can be. This allows a user to express the intent of a test exactly.
+
+An interesting special case is when we say `Times(0)`. You may have guessed - it
+means that the function shouldn't be called with the given arguments at all, and
+gMock will report a googletest failure whenever the function is (wrongfully)
+called.
+
+We've seen `AtLeast(n)` as an example of fuzzy cardinalities earlier. For the
+list of built-in cardinalities you can use, see
+[here](gmock_cheat_sheet.md#CardinalityList).
+
+The `Times()` clause can be omitted. **If you omit `Times()`, gMock will infer
+the cardinality for you.** The rules are easy to remember:
+
+* If **neither** `WillOnce()` **nor** `WillRepeatedly()` is in the
+ `EXPECT_CALL()`, the inferred cardinality is `Times(1)`.
+* If there are *n* `WillOnce()`'s but **no** `WillRepeatedly()`, where *n* >=
+ 1, the cardinality is `Times(n)`.
+* If there are *n* `WillOnce()`'s and **one** `WillRepeatedly()`, where *n* >=
+ 0, the cardinality is `Times(AtLeast(n))`.
+
+**Quick quiz:** what do you think will happen if a function is expected to be
+called twice but actually called four times?
+
+### Actions: What Should It Do?
+
+Remember that a mock object doesn't really have a working implementation? We as
+users have to tell it what to do when a method is invoked. This is easy in
+gMock.
+
+First, if the return type of a mock function is a built-in type or a pointer,
+the function has a **default action** (a `void` function will just return, a
+`bool` function will return `false`, and other functions will return 0). In
+addition, in C++ 11 and above, a mock function whose return type is
+default-constructible (i.e. has a default constructor) has a default action of
+returning a default-constructed value. If you don't say anything, this behavior
+will be used.
+
+Second, if a mock function doesn't have a default action, or the default action
+doesn't suit you, you can specify the action to be taken each time the
+expectation matches using a series of `WillOnce()` clauses followed by an
+optional `WillRepeatedly()`. For example,
+
+```cpp
+using ::testing::Return;
+...
+EXPECT_CALL(turtle, GetX())
+ .WillOnce(Return(100))
+ .WillOnce(Return(200))
+ .WillOnce(Return(300));
+```
+
+says that `turtle.GetX()` will be called *exactly three times* (gMock inferred
+this from how many `WillOnce()` clauses we've written, since we didn't
+explicitly write `Times()`), and will return 100, 200, and 300 respectively.
+
+```cpp
+using ::testing::Return;
+...
+EXPECT_CALL(turtle, GetY())
+ .WillOnce(Return(100))
+ .WillOnce(Return(200))
+ .WillRepeatedly(Return(300));
+```
+
+says that `turtle.GetY()` will be called *at least twice* (gMock knows this as
+we've written two `WillOnce()` clauses and a `WillRepeatedly()` while having no
+explicit `Times()`), will return 100 and 200 respectively the first two times,
+and 300 from the third time on.
+
+Of course, if you explicitly write a `Times()`, gMock will not try to infer the
+cardinality itself. What if the number you specified is larger than there are
+`WillOnce()` clauses? Well, after all `WillOnce()`s are used up, gMock will do
+the *default* action for the function every time (unless, of course, you have a
+`WillRepeatedly()`.).
+
+What can we do inside `WillOnce()` besides `Return()`? You can return a
+reference using `ReturnRef(`*`variable`*`)`, or invoke a pre-defined function,
+among [others](gmock_cook_book.md#using-actions).
+
+**Important note:** The `EXPECT_CALL()` statement evaluates the action clause
+only once, even though the action may be performed many times. Therefore you
+must be careful about side effects. The following may not do what you want:
+
+```cpp
+using ::testing::Return;
+...
+int n = 100;
+EXPECT_CALL(turtle, GetX())
+ .Times(4)
+ .WillRepeatedly(Return(n++));
+```
+
+Instead of returning 100, 101, 102, ..., consecutively, this mock function will
+always return 100 as `n++` is only evaluated once. Similarly, `Return(new Foo)`
+will create a new `Foo` object when the `EXPECT_CALL()` is executed, and will
+return the same pointer every time. If you want the side effect to happen every
+time, you need to define a custom action, which we'll teach in the
+[cook book](gmock_cook_book.md).
+
+Time for another quiz! What do you think the following means?
+
+```cpp
+using ::testing::Return;
+...
+EXPECT_CALL(turtle, GetY())
+ .Times(4)
+ .WillOnce(Return(100));
+```
+
+Obviously `turtle.GetY()` is expected to be called four times. But if you think
+it will return 100 every time, think twice! Remember that one `WillOnce()`
+clause will be consumed each time the function is invoked and the default action
+will be taken afterwards. So the right answer is that `turtle.GetY()` will
+return 100 the first time, but **return 0 from the second time on**, as
+returning 0 is the default action for `int` functions.
+
+### Using Multiple Expectations {#MultiExpectations}
+
+So far we've only shown examples where you have a single expectation. More
+realistically, you'll specify expectations on multiple mock methods which may be
+from multiple mock objects.
+
+By default, when a mock method is invoked, gMock will search the expectations in
+the **reverse order** they are defined, and stop when an active expectation that
+matches the arguments is found (you can think of it as "newer rules override
+older ones."). If the matching expectation cannot take any more calls, you will
+get an upper-bound-violated failure. Here's an example:
+
+```cpp
+using ::testing::_;
+...
+EXPECT_CALL(turtle, Forward(_)); // #1
+EXPECT_CALL(turtle, Forward(10)) // #2
+ .Times(2);
+```
+
+If `Forward(10)` is called three times in a row, the third time it will be an
+error, as the last matching expectation (#2) has been saturated. If, however,
+the third `Forward(10)` call is replaced by `Forward(20)`, then it would be OK,
+as now #1 will be the matching expectation.
+
+{: .callout .note}
+**Note:** Why does gMock search for a match in the *reverse* order of the
+expectations? The reason is that this allows a user to set up the default
+expectations in a mock object's constructor or the test fixture's set-up phase
+and then customize the mock by writing more specific expectations in the test
+body. So, if you have two expectations on the same method, you want to put the
+one with more specific matchers **after** the other, or the more specific rule
+would be shadowed by the more general one that comes after it.
+
+{: .callout .tip}
+**Tip:** It is very common to start with a catch-all expectation for a method
+and `Times(AnyNumber())` (omitting arguments, or with `_` for all arguments, if
+overloaded). This makes any calls to the method expected. This is not necessary
+for methods that are not mentioned at all (these are "uninteresting"), but is
+useful for methods that have some expectations, but for which other calls are
+ok. See
+[Understanding Uninteresting vs Unexpected Calls](gmock_cook_book.md#uninteresting-vs-unexpected).
+
+### Ordered vs Unordered Calls {#OrderedCalls}
+
+By default, an expectation can match a call even though an earlier expectation
+hasn't been satisfied. In other words, the calls don't have to occur in the
+order the expectations are specified.
+
+Sometimes, you may want all the expected calls to occur in a strict order. To
+say this in gMock is easy:
+
+```cpp
+using ::testing::InSequence;
+...
+TEST(FooTest, DrawsLineSegment) {
+ ...
+ {
+ InSequence seq;
+
+ EXPECT_CALL(turtle, PenDown());
+ EXPECT_CALL(turtle, Forward(100));
+ EXPECT_CALL(turtle, PenUp());
+ }
+ Foo();
+}
+```
+
+By creating an object of type `InSequence`, all expectations in its scope are
+put into a *sequence* and have to occur *sequentially*. Since we are just
+relying on the constructor and destructor of this object to do the actual work,
+its name is really irrelevant.
+
+In this example, we test that `Foo()` calls the three expected functions in the
+order as written. If a call is made out-of-order, it will be an error.
+
+(What if you care about the relative order of some of the calls, but not all of
+them? Can you specify an arbitrary partial order? The answer is ... yes! The
+details can be found [here](gmock_cook_book.md#OrderedCalls).)
+
+### All Expectations Are Sticky (Unless Said Otherwise) {#StickyExpectations}
+
+Now let's do a quick quiz to see how well you can use this mock stuff already.
+How would you test that the turtle is asked to go to the origin *exactly twice*
+(you want to ignore any other instructions it receives)?
+
+After you've come up with your answer, take a look at ours and compare notes
+(solve it yourself first - don't cheat!):
+
+```cpp
+using ::testing::_;
+using ::testing::AnyNumber;
+...
+EXPECT_CALL(turtle, GoTo(_, _)) // #1
+ .Times(AnyNumber());
+EXPECT_CALL(turtle, GoTo(0, 0)) // #2
+ .Times(2);
+```
+
+Suppose `turtle.GoTo(0, 0)` is called three times. In the third time, gMock will
+see that the arguments match expectation #2 (remember that we always pick the
+last matching expectation). Now, since we said that there should be only two
+such calls, gMock will report an error immediately. This is basically what we've
+told you in the [Using Multiple Expectations](#MultiExpectations) section above.
+
+This example shows that **expectations in gMock are "sticky" by default**, in
+the sense that they remain active even after we have reached their invocation
+upper bounds. This is an important rule to remember, as it affects the meaning
+of the spec, and is **different** to how it's done in many other mocking
+frameworks (Why'd we do that? Because we think our rule makes the common cases
+easier to express and understand.).
+
+Simple? Let's see if you've really understood it: what does the following code
+say?
+
+```cpp
+using ::testing::Return;
+...
+for (int i = n; i > 0; i--) {
+ EXPECT_CALL(turtle, GetX())
+ .WillOnce(Return(10*i));
+}
+```
+
+If you think it says that `turtle.GetX()` will be called `n` times and will
+return 10, 20, 30, ..., consecutively, think twice! The problem is that, as we
+said, expectations are sticky. So, the second time `turtle.GetX()` is called,
+the last (latest) `EXPECT_CALL()` statement will match, and will immediately
+lead to an "upper bound violated" error - this piece of code is not very useful!
+
+One correct way of saying that `turtle.GetX()` will return 10, 20, 30, ..., is
+to explicitly say that the expectations are *not* sticky. In other words, they
+should *retire* as soon as they are saturated:
+
+```cpp
+using ::testing::Return;
+...
+for (int i = n; i > 0; i--) {
+ EXPECT_CALL(turtle, GetX())
+ .WillOnce(Return(10*i))
+ .RetiresOnSaturation();
+}
+```
+
+And, there's a better way to do it: in this case, we expect the calls to occur
+in a specific order, and we line up the actions to match the order. Since the
+order is important here, we should make it explicit using a sequence:
+
+```cpp
+using ::testing::InSequence;
+using ::testing::Return;
+...
+{
+ InSequence s;
+
+ for (int i = 1; i <= n; i++) {
+ EXPECT_CALL(turtle, GetX())
+ .WillOnce(Return(10*i))
+ .RetiresOnSaturation();
+ }
+}
+```
+
+By the way, the other situation where an expectation may *not* be sticky is when
+it's in a sequence - as soon as another expectation that comes after it in the
+sequence has been used, it automatically retires (and will never be used to
+match any call).
+
+### Uninteresting Calls
+
+A mock object may have many methods, and not all of them are that interesting.
+For example, in some tests we may not care about how many times `GetX()` and
+`GetY()` get called.
+
+In gMock, if you are not interested in a method, just don't say anything about
+it. If a call to this method occurs, you'll see a warning in the test output,
+but it won't be a failure. This is called "naggy" behavior; to change, see
+[The Nice, the Strict, and the Naggy](gmock_cook_book.md#NiceStrictNaggy).

+## Using GoogleTest from various build systems
+
+GoogleTest comes with pkg-config files that can be used to determine all
+necessary flags for compiling and linking to GoogleTest (and GoogleMock).
+Pkg-config is a standardised plain-text format containing
+
+* the includedir (-I) path
+* necessary macro (-D) definitions
+* further required flags (-pthread)
+* the library (-L) path
+* the library (-l) to link to
+
+All current build systems support pkg-config in one way or another. For all
+examples here we assume you want to compile the sample
+`samples/sample3_unittest.cc`.
+
+### CMake
+
+Using `pkg-config` in CMake is fairly easy:
+
+```cmake
+cmake_minimum_required(VERSION 3.0)
+
+cmake_policy(SET CMP0048 NEW)
+project(my_gtest_pkgconfig VERSION 0.0.1 LANGUAGES CXX)
+
+find_package(PkgConfig)
+pkg_search_module(GTEST REQUIRED gtest_main)
+
+add_executable(testapp samples/sample3_unittest.cc)
+target_link_libraries(testapp ${GTEST_LDFLAGS})
+target_compile_options(testapp PUBLIC ${GTEST_CFLAGS})
+
+include(CTest)
+add_test(first_and_only_test testapp)
+```
+
+It is generally recommended that you use `target_compile_options` + `_CFLAGS`
+over `target_include_directories` + `_INCLUDE_DIRS` as the former includes not
+just -I flags (GoogleTest might require a macro indicating to internal headers
+that all libraries have been compiled with threading enabled. In addition,
+GoogleTest might also require `-pthread` in the compiling step, and as such
+splitting the pkg-config `Cflags` variable into include dirs and macros for
+`target_compile_definitions()` might still miss this). The same recommendation
+goes for using `_LDFLAGS` over the more commonplace `_LIBRARIES`, which happens
+to discard `-L` flags and `-pthread`.
+
+### Help! pkg-config can't find GoogleTest!
+
+Let's say you have a `CMakeLists.txt` along the lines of the one in this
+tutorial and you try to run `cmake`. It is very possible that you get a failure
+along the lines of:
+
+```
+-- Checking for one of the modules 'gtest_main'
+CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:640 (message):
+ None of the required 'gtest_main' found
+```
+
+These failures are common if you installed GoogleTest yourself and have not
+sourced it from a distro or other package manager. If so, you need to tell
+pkg-config where it can find the `.pc` files containing the information. Say you
+installed GoogleTest to `/usr/local`, then it might be that the `.pc` files are
+installed under `/usr/local/lib64/pkgconfig`. If you set
+
+```
+export PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig
+```
+
+pkg-config will also try to look in `PKG_CONFIG_PATH` to find `gtest_main.pc`.
+
+### Using pkg-config in a cross-compilation setting
+
+Pkg-config can be used in a cross-compilation setting too. To do this, let's
+assume the final prefix of the cross-compiled installation will be `/usr`, and
+your sysroot is `/home/MYUSER/sysroot`. Configure and install GTest using
+
+```
+mkdir build && cmake -DCMAKE_INSTALL_PREFIX=/usr ..
+```
+
+Install into the sysroot using `DESTDIR`:
+
+```
+make -j install DESTDIR=/home/MYUSER/sysroot
+```
+
+Before we continue, it is recommended to **always** define the following two
+variables for pkg-config in a cross-compilation setting:
+
+```
+export PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=yes
+export PKG_CONFIG_ALLOW_SYSTEM_LIBS=yes
+```
+
+otherwise `pkg-config` will filter `-I` and `-L` flags against standard prefixes
+such as `/usr` (see https://bugs.freedesktop.org/show_bug.cgi?id=28264#c3 for
+reasons why this stripping needs to occur usually).
+
+If you look at the generated pkg-config file, it will look something like
+
+```
+libdir=/usr/lib64
+includedir=/usr/include
+
+Name: gtest
+Description: GoogleTest (without main() function)
+Version: 1.11.0
+URL: https://github.com/google/googletest
+Libs: -L${libdir} -lgtest -lpthread
+Cflags: -I${includedir} -DGTEST_HAS_PTHREAD=1 -lpthread
+```
+
+Notice that the sysroot is not included in `libdir` and `includedir`! If you try
+to run `pkg-config` with the correct
+`PKG_CONFIG_LIBDIR=/home/MYUSER/sysroot/usr/lib64/pkgconfig` against this `.pc`
+file, you will get
+
+```
+$ pkg-config --cflags gtest
+-DGTEST_HAS_PTHREAD=1 -lpthread -I/usr/include
+$ pkg-config --libs gtest
+-L/usr/lib64 -lgtest -lpthread
+```
+
+which is obviously wrong and points to the `CBUILD` and not `CHOST` root. In
+order to use this in a cross-compilation setting, we need to tell pkg-config to
+inject the actual sysroot into `-I` and `-L` variables. Let us now tell
+pkg-config about the actual sysroot
+
+```
+export PKG_CONFIG_DIR=
+export PKG_CONFIG_SYSROOT_DIR=/home/MYUSER/sysroot
+export PKG_CONFIG_LIBDIR=${PKG_CONFIG_SYSROOT_DIR}/usr/lib64/pkgconfig
+```
+
+and running `pkg-config` again we get
+
+```
+$ pkg-config --cflags gtest
+-DGTEST_HAS_PTHREAD=1 -lpthread -I/home/MYUSER/sysroot/usr/include
+$ pkg-config --libs gtest
+-L/home/MYUSER/sysroot/usr/lib64 -lgtest -lpthread
+```
+
+which contains the correct sysroot now. For a more comprehensive guide to also
+including `${CHOST}` in build system calls, see the excellent tutorial by Diego
+Elio Pettenò: <https://autotools.io/pkgconfig/cross-compiling.html>

+# Googletest Primer
+
+## Introduction: Why googletest?
+
+*googletest* helps you write better C++ tests.
+
+googletest is a testing framework developed by the Testing Technology team with
+Google's specific requirements and constraints in mind. Whether you work on
+Linux, Windows, or a Mac, if you write C++ code, googletest can help you. And it
+supports *any* kind of tests, not just unit tests.
+
+So what makes a good test, and how does googletest fit in? We believe:
+
+1. Tests should be *independent* and *repeatable*. It's a pain to debug a test
+ that succeeds or fails as a result of other tests. googletest isolates the
+ tests by running each of them on a different object. When a test fails,
+ googletest allows you to run it in isolation for quick debugging.
+2. Tests should be well *organized* and reflect the structure of the tested
+ code. googletest groups related tests into test suites that can share data
+ and subroutines. This common pattern is easy to recognize and makes tests
+ easy to maintain. Such consistency is especially helpful when people switch
+ projects and start to work on a new code base.
+3. Tests should be *portable* and *reusable*. Google has a lot of code that is
+ platform-neutral; its tests should also be platform-neutral. googletest
+ works on different OSes, with different compilers, with or without
+ exceptions, so googletest tests can work with a variety of configurations.
+4. When tests fail, they should provide as much *information* about the problem
+ as possible. googletest doesn't stop at the first test failure. Instead, it
+ only stops the current test and continues with the next. You can also set up
+ tests that report non-fatal failures after which the current test continues.
+ Thus, you can detect and fix multiple bugs in a single run-edit-compile
+ cycle.
+5. The testing framework should liberate test writers from housekeeping chores
+ and let them focus on the test *content*. googletest automatically keeps
+ track of all tests defined, and doesn't require the user to enumerate them
+ in order to run them.
+6. Tests should be *fast*. With googletest, you can reuse shared resources
+ across tests and pay for the set-up/tear-down only once, without making
+ tests depend on each other.
+
+Since googletest is based on the popular xUnit architecture, you'll feel right
+at home if you've used JUnit or PyUnit before. If not, it will take you about 10
+minutes to learn the basics and get started. So let's go!
+
+## Beware of the nomenclature
+
+{: .callout .note}
+_Note:_ There might be some confusion arising from different definitions of the
+terms _Test_, _Test Case_ and _Test Suite_, so beware of misunderstanding these.
+
+Historically, googletest started to use the term _Test Case_ for grouping
+related tests, whereas current publications, including International Software
+Testing Qualifications Board ([ISTQB](http://www.istqb.org/)) materials and
+various textbooks on software quality, use the term
+_[Test Suite][istqb test suite]_ for this.
+
+The related term _Test_, as it is used in googletest, corresponds to the term
+_[Test Case][istqb test case]_ of ISTQB and others.
+
+The term _Test_ is commonly of broad enough sense, including ISTQB's definition
+of _Test Case_, so it's not much of a problem here. But the term _Test Case_ as
+was used in Google Test is of contradictory sense and thus confusing.
+
+googletest recently started replacing the term _Test Case_ with _Test Suite_.
+The preferred API is *TestSuite*. The older TestCase API is being slowly
+deprecated and refactored away.
+
+So please be aware of the different definitions of the terms:
+
+

+[istqb test suite]: http://glossary.istqb.org/en/search/test%20suite
+
+## Basic Concepts
+
+When using googletest, you start by writing *assertions*, which are statements
+that check whether a condition is true. An assertion's result can be *success*,
+*nonfatal failure*, or *fatal failure*. If a fatal failure occurs, it aborts the
+current function; otherwise the program continues normally.
+
+*Tests* use assertions to verify the tested code's behavior. If a test crashes
+or has a failed assertion, then it *fails*; otherwise it *succeeds*.
+
+A *test suite* contains one or many tests. You should group your tests into test
+suites that reflect the structure of the tested code. When multiple tests in a
+test suite need to share common objects and subroutines, you can put them into a
+*test fixture* class.
+
+A *test program* can contain multiple test suites.
+
+We'll now explain how to write a test program, starting at the individual
+assertion level and building up to tests and test suites.
+
+## Assertions
+
+googletest assertions are macros that resemble function calls. You test a class
+or function by making assertions about its behavior. When an assertion fails,
+googletest prints the assertion's source file and line number location, along
+with a failure message. You may also supply a custom failure message which will
+be appended to googletest's message.
+
+The assertions come in pairs that test the same thing but have different effects
+on the current function. `ASSERT_*` versions generate fatal failures when they
+fail, and **abort the current function**. `EXPECT_*` versions generate nonfatal
+failures, which don't abort the current function. Usually `EXPECT_*` are
+preferred, as they allow more than one failure to be reported in a test.
+However, you should use `ASSERT_*` if it doesn't make sense to continue when the
+assertion in question fails.
+
+Since a failed `ASSERT_*` returns from the current function immediately,
+possibly skipping clean-up code that comes after it, it may cause a space leak.
+Depending on the nature of the leak, it may or may not be worth fixing - so keep
+this in mind if you get a heap checker error in addition to assertion errors.
+
+To provide a custom failure message, simply stream it into the macro using the
+`<<` operator or a sequence of such operators. See the following example, using
+the [`ASSERT_EQ` and `EXPECT_EQ`](reference/assertions.md#EXPECT_EQ) macros to
+verify value equality:
+
+```c++
+ASSERT_EQ(x.size(), y.size()) << "Vectors x and y are of unequal length";
+
+for (int i = 0; i < x.size(); ++i) {
+ EXPECT_EQ(x[i], y[i]) << "Vectors x and y differ at index " << i;
+}
+```
+
+Anything that can be streamed to an `ostream` can be streamed to an assertion
+macro--in particular, C strings and `string` objects. If a wide string
+(`wchar_t*`, `TCHAR*` in `UNICODE` mode on Windows, or `std::wstring`) is
+streamed to an assertion, it will be translated to UTF-8 when printed.
+
+GoogleTest provides a collection of assertions for verifying the behavior of
+your code in various ways. You can check Boolean conditions, compare values
+based on relational operators, verify string values, floating-point values, and
+much more. There are even assertions that enable you to verify more complex
+states by providing custom predicates. For the complete list of assertions
+provided by GoogleTest, see the [Assertions Reference](reference/assertions.md).
+
+## Simple Tests
+
+To create a test:
+
+1. Use the `TEST()` macro to define and name a test function. These are
+ ordinary C++ functions that don't return a value.
+2. In this function, along with any valid C++ statements you want to include,
+ use the various googletest assertions to check values.
+3. The test's result is determined by the assertions; if any assertion in the
+ test fails (either fatally or non-fatally), or if the test crashes, the
+ entire test fails. Otherwise, it succeeds.
+
+```c++
+TEST(TestSuiteName, TestName) {
+ ... test body ...
+}
+```
+
+`TEST()` arguments go from general to specific. The *first* argument is the name
+of the test suite, and the *second* argument is the test's name within the test
+suite. Both names must be valid C++ identifiers, and they should not contain any
+underscores (`_`). A test's *full name* consists of its containing test suite
+and its individual name. Tests from different test suites can have the same
+individual name.
+
+For example, let's take a simple integer function:
+
+```c++
+int Factorial(int n); // Returns the factorial of n
+```
+
+A test suite for this function might look like:
+
+```c++
+// Tests factorial of 0.
+TEST(FactorialTest, HandlesZeroInput) {
+ EXPECT_EQ(Factorial(0), 1);
+}
+
+// Tests factorial of positive numbers.
+TEST(FactorialTest, HandlesPositiveInput) {
+ EXPECT_EQ(Factorial(1), 1);
+ EXPECT_EQ(Factorial(2), 2);
+ EXPECT_EQ(Factorial(3), 6);
+ EXPECT_EQ(Factorial(8), 40320);
+}
+```
+
+googletest groups the test results by test suites, so logically related tests
+should be in the same test suite; in other words, the first argument to their
+`TEST()` should be the same. In the above example, we have two tests,
+`HandlesZeroInput` and `HandlesPositiveInput`, that belong to the same test
+suite `FactorialTest`.
+
+When naming your test suites and tests, you should follow the same convention as
+for
+[naming functions and classes](https://google.github.io/styleguide/cppguide.html#Function_Names).
+
+**Availability**: Linux, Windows, Mac.
+
+## Test Fixtures: Using the Same Data Configuration for Multiple Tests {#same-data-multiple-tests}
+
+If you find yourself writing two or more tests that operate on similar data, you
+can use a *test fixture*. This allows you to reuse the same configuration of
+objects for several different tests.
+
+To create a fixture:
+
+1. Derive a class from `::testing::Test` . Start its body with `protected:`, as
+ we'll want to access fixture members from sub-classes.
+2. Inside the class, declare any objects you plan to use.
+3. If necessary, write a default constructor or `SetUp()` function to prepare
+ the objects for each test. A common mistake is to spell `SetUp()` as
+ **`Setup()`** with a small `u` - Use `override` in C++11 to make sure you
+ spelled it correctly.
+4. If necessary, write a destructor or `TearDown()` function to release any
+ resources you allocated in `SetUp()` . To learn when you should use the
+ constructor/destructor and when you should use `SetUp()/TearDown()`, read
+ the [FAQ](faq.md#CtorVsSetUp).
+5. If needed, define subroutines for your tests to share.
+
+When using a fixture, use `TEST_F()` instead of `TEST()` as it allows you to
+access objects and subroutines in the test fixture:
+
+```c++
+TEST_F(TestFixtureName, TestName) {
+ ... test body ...
+}
+```
+
+Like `TEST()`, the first argument is the test suite name, but for `TEST_F()`
+this must be the name of the test fixture class. You've probably guessed: `_F`
+is for fixture.
+
+Unfortunately, the C++ macro system does not allow us to create a single macro
+that can handle both types of tests. Using the wrong macro causes a compiler
+error.
+
+Also, you must first define a test fixture class before using it in a
+`TEST_F()`, or you'll get the compiler error "`virtual outside class
+declaration`".
+
+For each test defined with `TEST_F()`, googletest will create a *fresh* test
+fixture at runtime, immediately initialize it via `SetUp()`, run the test, clean
+up by calling `TearDown()`, and then delete the test fixture. Note that
+different tests in the same test suite have different test fixture objects, and
+googletest always deletes a test fixture before it creates the next one.
+googletest does **not** reuse the same test fixture for multiple tests. Any
+changes one test makes to the fixture do not affect other tests.
+
+As an example, let's write tests for a FIFO queue class named `Queue`, which has
+the following interface:
+
+```c++
+template <typename E> // E is the element type.
+class Queue {
+ public:
+ Queue();
+ void Enqueue(const E& element);
+ E* Dequeue(); // Returns NULL if the queue is empty.
+ size_t size() const;
+ ...
+};
+```
+
+First, define a fixture class. By convention, you should give it the name
+`FooTest` where `Foo` is the class being tested.
+
+```c++
+class QueueTest : public ::testing::Test {
+ protected:
+ void SetUp() override {
+ q0_.Enqueue(1);
+ q1_.Enqueue(2);
+ q2_.Enqueue(3);
+ }
+
+ // void TearDown() override {}
+
+ Queue<int> q0_;
+ Queue<int> q1_;
+ Queue<int> q2_;
+};
+```
+
+In this case, `TearDown()` is not needed since we don't have to clean up after
+each test, other than what's already done by the destructor.
+
+Now we'll write tests using `TEST_F()` and this fixture.
+
+```c++
+TEST_F(QueueTest, IsEmptyInitially) {
+ EXPECT_EQ(q0_.size(), 0);
+}
+
+TEST_F(QueueTest, DequeueWorks) {
+ int* n = q0_.Dequeue();
+ EXPECT_EQ(n, nullptr);
+
+ n = q1_.Dequeue();
+ ASSERT_NE(n, nullptr);
+ EXPECT_EQ(*n, 1);
+ EXPECT_EQ(q1_.size(), 0);
+ delete n;
+
+ n = q2_.Dequeue();
+ ASSERT_NE(n, nullptr);
+ EXPECT_EQ(*n, 2);
+ EXPECT_EQ(q2_.size(), 1);
+ delete n;
+}
+```
+
+The above uses both `ASSERT_*` and `EXPECT_*` assertions. The rule of thumb is
+to use `EXPECT_*` when you want the test to continue to reveal more errors after
+the assertion failure, and use `ASSERT_*` when continuing after failure doesn't
+make sense. For example, the second assertion in the `Dequeue` test is
+`ASSERT_NE(n, nullptr)`, as we need to dereference the pointer `n` later, which
+would lead to a segfault when `n` is `NULL`.
+
+When these tests run, the following happens:
+
+1. googletest constructs a `QueueTest` object (let's call it `t1`).
+2. `t1.SetUp()` initializes `t1`.
+3. The first test (`IsEmptyInitially`) runs on `t1`.
+4. `t1.TearDown()` cleans up after the test finishes.
+5. `t1` is destructed.
+6. The above steps are repeated on another `QueueTest` object, this time
+ running the `DequeueWorks` test.
+
+**Availability**: Linux, Windows, Mac.
+
+## Invoking the Tests
+
+`TEST()` and `TEST_F()` implicitly register their tests with googletest. So,
+unlike with many other C++ testing frameworks, you don't have to re-list all
+your defined tests in order to run them.
+
+After defining your tests, you can run them with `RUN_ALL_TESTS()`, which
+returns `0` if all the tests are successful, or `1` otherwise. Note that
+`RUN_ALL_TESTS()` runs *all tests* in your link unit--they can be from different
+test suites, or even different source files.
+
+When invoked, the `RUN_ALL_TESTS()` macro:
+
+* Saves the state of all googletest flags.
+
+* Creates a test fixture object for the first test.
+
+* Initializes it via `SetUp()`.
+
+* Runs the test on the fixture object.
+
+* Cleans up the fixture via `TearDown()`.
+
+* Deletes the fixture.
+
+* Restores the state of all googletest flags.
+
+* Repeats the above steps for the next test, until all tests have run.
+
+If a fatal failure happens the subsequent steps will be skipped.
+
+{: .callout .important}
+> IMPORTANT: You must **not** ignore the return value of `RUN_ALL_TESTS()`, or
+> you will get a compiler error. The rationale for this design is that the
+> automated testing service determines whether a test has passed based on its
+> exit code, not on its stdout/stderr output; thus your `main()` function must
+> return the value of `RUN_ALL_TESTS()`.
+>
+> Also, you should call `RUN_ALL_TESTS()` only **once**. Calling it more than
+> once conflicts with some advanced googletest features (e.g., thread-safe
+> [death tests](advanced.md#death-tests)) and thus is not supported.
+
+**Availability**: Linux, Windows, Mac.
+
+## Writing the main() Function
+
+Most users should _not_ need to write their own `main` function and instead link
+with `gtest_main` (as opposed to with `gtest`), which defines a suitable entry
+point. See the end of this section for details. The remainder of this section
+should only apply when you need to do something custom before the tests run that
+cannot be expressed within the framework of fixtures and test suites.
+
+If you write your own `main` function, it should return the value of
+`RUN_ALL_TESTS()`.
+
+You can start from this boilerplate:
+
+```c++
+#include "this/package/foo.h"
+
+#include "gtest/gtest.h"
+
+namespace my {
+namespace project {
+namespace {
+
+// The fixture for testing class Foo.
+class FooTest : public ::testing::Test {
+ protected:
+ // You can remove any or all of the following functions if their bodies would
+ // be empty.
+
+ FooTest() {
+ // You can do set-up work for each test here.
+ }
+
+ ~FooTest() override {
+ // You can do clean-up work that doesn't throw exceptions here.
+ }
+
+ // If the constructor and destructor are not enough for setting up
+ // and cleaning up each test, you can define the following methods:
+
+ void SetUp() override {
+ // Code here will be called immediately after the constructor (right
+ // before each test).
+ }
+
+ void TearDown() override {
+ // Code here will be called immediately after each test (right
+ // before the destructor).
+ }
+
+ // Class members declared here can be used by all tests in the test suite
+ // for Foo.
+};
+
+// Tests that the Foo::Bar() method does Abc.
+TEST_F(FooTest, MethodBarDoesAbc) {
+ const std::string input_filepath = "this/package/testdata/myinputfile.dat";
+ const std::string output_filepath = "this/package/testdata/myoutputfile.dat";
+ Foo f;
+ EXPECT_EQ(f.Bar(input_filepath, output_filepath), 0);
+}
+
+// Tests that Foo does Xyz.
+TEST_F(FooTest, DoesXyz) {
+ // Exercises the Xyz feature of Foo.
+}
+
+} // namespace
+} // namespace project
+} // namespace my
+
+int main(int argc, char **argv) {
+ ::testing::InitGoogleTest(&argc, argv);
+ return RUN_ALL_TESTS();
+}
+```
+
+The `::testing::InitGoogleTest()` function parses the command line for
+googletest flags, and removes all recognized flags. This allows the user to
+control a test program's behavior via various flags, which we'll cover in the
+[AdvancedGuide](advanced.md). You **must** call this function before calling
+`RUN_ALL_TESTS()`, or the flags won't be properly initialized.
+
+On Windows, `InitGoogleTest()` also works with wide strings, so it can be used
+in programs compiled in `UNICODE` mode as well.
+
+But maybe you think that writing all those `main` functions is too much work? We
+agree with you completely, and that's why Google Test provides a basic
+implementation of main(). If it fits your needs, then just link your test with
+the `gtest_main` library and you are good to go.
+
+{: .callout .note}
+NOTE: `ParseGUnitFlags()` is deprecated in favor of `InitGoogleTest()`.
+
+## Known Limitations
+
+* Google Test is designed to be thread-safe. The implementation is thread-safe
+ on systems where the `pthreads` library is available. It is currently
+ _unsafe_ to use Google Test assertions from two threads concurrently on
+ other systems (e.g. Windows). In most tests this is not an issue as usually
+ the assertions are done in the main thread. If you want to help, you can
+ volunteer to implement the necessary synchronization primitives in
+ `gtest-port.h` for your platform.

+# Quickstart: Building with Bazel
+
+This tutorial aims to get you up and running with GoogleTest using the Bazel
+build system. If you're using GoogleTest for the first time or need a refresher,
+we recommend this tutorial as a starting point.
+
+## Prerequisites
+
+To complete this tutorial, you'll need:
+
+* A compatible operating system (e.g. Linux, macOS, Windows).
+* A compatible C++ compiler that supports at least C++11.
+* [Bazel](https://bazel.build/), the preferred build system used by the
+ GoogleTest team.
+
+See [Supported Platforms](platforms.md) for more information about platforms
+compatible with GoogleTest.
+
+If you don't already have Bazel installed, see the
+[Bazel installation guide](https://docs.bazel.build/versions/main/install.html).
+
+{: .callout .note}
+Note: The terminal commands in this tutorial show a Unix shell prompt, but the
+commands work on the Windows command line as well.
+
+## Set up a Bazel workspace
+
+A
+[Bazel workspace](https://docs.bazel.build/versions/main/build-ref.html#workspace)
+is a directory on your filesystem that you use to manage source files for the
+software you want to build. Each workspace directory has a text file named
+`WORKSPACE` which may be empty, or may contain references to external
+dependencies required to build the outputs.
+
+First, create a directory for your workspace:
+
+```
+$ mkdir my_workspace && cd my_workspace
+```
+
+Next, you’ll create the `WORKSPACE` file to specify dependencies. A common and
+recommended way to depend on GoogleTest is to use a
+[Bazel external dependency](https://docs.bazel.build/versions/main/external.html)
+via the
+[`http_archive` rule](https://docs.bazel.build/versions/main/repo/http.html#http_archive).
+To do this, in the root directory of your workspace (`my_workspace/`), create a
+file named `WORKSPACE` with the following contents:
+
+```
+load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
+
+http_archive(
+ name = "com_google_googletest",
+ urls = ["https://github.com/google/googletest/archive/609281088cfefc76f9d0ce82e1ff6c30cc3591e5.zip"],
+ strip_prefix = "googletest-609281088cfefc76f9d0ce82e1ff6c30cc3591e5",
+)
+```
+
+The above configuration declares a dependency on GoogleTest which is downloaded
+as a ZIP archive from GitHub. In the above example,
+`609281088cfefc76f9d0ce82e1ff6c30cc3591e5` is the Git commit hash of the
+GoogleTest version to use; we recommend updating the hash often to point to the
+latest version.
+
+Now you're ready to build C++ code that uses GoogleTest.
+
+## Create and run a binary
+
+With your Bazel workspace set up, you can now use GoogleTest code within your
+own project.
+
+As an example, create a file named `hello_test.cc` in your `my_workspace`
+directory with the following contents:
+
+```cpp
+#include <gtest/gtest.h>
+
+// Demonstrate some basic assertions.
+TEST(HelloTest, BasicAssertions) {
+ // Expect two strings not to be equal.
+ EXPECT_STRNE("hello", "world");
+ // Expect equality.
+ EXPECT_EQ(7 * 6, 42);
+}
+```
+
+GoogleTest provides [assertions](primer.md#assertions) that you use to test the
+behavior of your code. The above sample includes the main GoogleTest header file
+and demonstrates some basic assertions.
+
+To build the code, create a file named `BUILD` in the same directory with the
+following contents:
+
+```
+cc_test(
+ name = "hello_test",
+ size = "small",
+ srcs = ["hello_test.cc"],
+ deps = ["@com_google_googletest//:gtest_main"],
+)
+```
+
+This `cc_test` rule declares the C++ test binary you want to build, and links to
+GoogleTest (`//:gtest_main`) using the prefix you specified in the `WORKSPACE`
+file (`@com_google_googletest`). For more information about Bazel `BUILD` files,
+see the
+[Bazel C++ Tutorial](https://docs.bazel.build/versions/main/tutorial/cpp.html).
+
+Now you can build and run your test:
+
+<pre>
+<strong>my_workspace$ bazel test --test_output=all //:hello_test</strong>
+INFO: Analyzed target //:hello_test (26 packages loaded, 362 targets configured).

+
+Congratulations! You've successfully built and run a test binary using
+GoogleTest.

+## Prerequisites
+
+To complete this tutorial, you'll need:
+
+* A compatible operating system (e.g. Linux, macOS, Windows).

+
+## Set up a project
+
+CMake uses a file named `CMakeLists.txt` to configure the build system for a

+
+First, create a directory for your project:
+
+```
+$ mkdir my_project && cd my_project
+```
+
+Next, you'll create the `CMakeLists.txt` file and declare a dependency on
+GoogleTest. There are many ways to express dependencies in the CMake ecosystem;
+in this quickstart, you'll use the
+[`FetchContent` CMake module](https://cmake.org/cmake/help/latest/module/FetchContent.html).
+To do this, in your project directory (`my_project`), create a file named
+`CMakeLists.txt` with the following contents:
+
+```cmake
+cmake_minimum_required(VERSION 3.14)
+project(my_project)
+
+# GoogleTest requires at least C++11
+set(CMAKE_CXX_STANDARD 11)
+
+include(FetchContent)
+FetchContent_Declare(
+ googletest
+ URL https://github.com/google/googletest/archive/609281088cfefc76f9d0ce82e1ff6c30cc3591e5.zip
+)
+# For Windows: Prevent overriding the parent project's compiler/linker settings
+set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
+FetchContent_MakeAvailable(googletest)
+```
+
+The above configuration declares a dependency on GoogleTest which is downloaded
+from GitHub. In the above example, `609281088cfefc76f9d0ce82e1ff6c30cc3591e5` is
+the Git commit hash of the GoogleTest version to use; we recommend updating the
+hash often to point to the latest version.
+
+For more information about how to create `CMakeLists.txt` files, see the
+[CMake Tutorial](https://cmake.org/cmake/help/latest/guide/tutorial/index.html).
+
+## Create and run a binary
+
+With GoogleTest declared as a dependency, you can use GoogleTest code within
+your own project.
+
+As an example, create a file named `hello_test.cc` in your `my_project`
+directory with the following contents:
+
+```cpp
+#include <gtest/gtest.h>
+
+// Demonstrate some basic assertions.
+TEST(HelloTest, BasicAssertions) {
+ // Expect two strings not to be equal.
+ EXPECT_STRNE("hello", "world");
+ // Expect equality.
+ EXPECT_EQ(7 * 6, 42);
+}
+```
+
+GoogleTest provides [assertions](primer.md#assertions) that you use to test the
+behavior of your code. The above sample includes the main GoogleTest header file
+and demonstrates some basic assertions.
+
+To build the code, add the following to the end of your `CMakeLists.txt` file:
+
+```cmake
+enable_testing()
+
+add_executable(
+ hello_test
+ hello_test.cc
+)
+target_link_libraries(
+ hello_test
+ gtest_main
+)
+
+include(GoogleTest)
+gtest_discover_tests(hello_test)
+```
+
+The above configuration enables testing in CMake, declares the C++ test binary
+you want to build (`hello_test`), and links it to GoogleTest (`gtest_main`). The
+last two lines enable CMake's test runner to discover the tests included in the
+binary, using the
+[`GoogleTest` CMake module](https://cmake.org/cmake/help/git-stage/module/GoogleTest.html).
+
+Now you can build and run your test:
+
+<pre>
+<strong>my_project$ cmake -S . -B build</strong>
+-- The C compiler identification is GNU 10.2.1
+-- The CXX compiler identification is GNU 10.2.1
+...
+-- Build files have been written to: .../my_project/build

+
+100% tests passed, 0 tests failed out of 1
+
+Total Test time (real) = 0.01 sec
+</pre>
+
+Congratulations! You've successfully built and run a test binary using
+GoogleTest.

+# Actions Reference
+
+[**Actions**](../gmock_for_dummies.md#actions-what-should-it-do) specify what a
+mock function should do when invoked. This page lists the built-in actions
+provided by GoogleTest. All actions are defined in the `::testing` namespace.
+
+## Returning a Value
+
+| Action | Description |
+| :-------------------------------- | :-------------------------------------------- |
+| `Return()` | Return from a `void` mock function. |
+| `Return(value)` | Return `value`. If the type of `value` is different to the mock function's return type, `value` is converted to the latter type <i>at the time the expectation is set</i>, not when the action is executed. |
+| `ReturnArg<N>()` | Return the `N`-th (0-based) argument. |
+| `ReturnNew<T>(a1, ..., ak)` | Return `new T(a1, ..., ak)`; a different object is created each time. |
+| `ReturnNull()` | Return a null pointer. |
+| `ReturnPointee(ptr)` | Return the value pointed to by `ptr`. |
+| `ReturnRef(variable)` | Return a reference to `variable`. |
+| `ReturnRefOfCopy(value)` | Return a reference to a copy of `value`; the copy lives as long as the action. |
+| `ReturnRoundRobin({a1, ..., ak})` | Each call will return the next `ai` in the list, starting at the beginning when the end of the list is reached. |
+
+## Side Effects
+
+| Action | Description |
+| :--------------------------------- | :-------------------------------------- |
+| `Assign(&variable, value)` | Assign `value` to variable. |
+| `DeleteArg<N>()` | Delete the `N`-th (0-based) argument, which must be a pointer. |
+| `SaveArg<N>(pointer)` | Save the `N`-th (0-based) argument to `*pointer`. |
+| `SaveArgPointee<N>(pointer)` | Save the value pointed to by the `N`-th (0-based) argument to `*pointer`. |
+| `SetArgReferee<N>(value)` | Assign `value` to the variable referenced by the `N`-th (0-based) argument. |
+| `SetArgPointee<N>(value)` | Assign `value` to the variable pointed by the `N`-th (0-based) argument. |
+| `SetArgumentPointee<N>(value)` | Same as `SetArgPointee<N>(value)`. Deprecated. Will be removed in v1.7.0. |
+| `SetArrayArgument<N>(first, last)` | Copies the elements in source range [`first`, `last`) to the array pointed to by the `N`-th (0-based) argument, which can be either a pointer or an iterator. The action does not take ownership of the elements in the source range. |
+| `SetErrnoAndReturn(error, value)` | Set `errno` to `error` and return `value`. |
+| `Throw(exception)` | Throws the given exception, which can be any copyable value. Available since v1.1.0. |
+
+## Using a Function, Functor, or Lambda as an Action
+
+In the following, by "callable" we mean a free function, `std::function`,
+functor, or lambda.
+
+| Action | Description |
+| :---------------------------------- | :------------------------------------- |
+| `f` | Invoke `f` with the arguments passed to the mock function, where `f` is a callable. |
+| `Invoke(f)` | Invoke `f` with the arguments passed to the mock function, where `f` can be a global/static function or a functor. |
+| `Invoke(object_pointer, &class::method)` | Invoke the method on the object with the arguments passed to the mock function. |
+| `InvokeWithoutArgs(f)` | Invoke `f`, which can be a global/static function or a functor. `f` must take no arguments. |
+| `InvokeWithoutArgs(object_pointer, &class::method)` | Invoke the method on the object, which takes no arguments. |
+| `InvokeArgument<N>(arg1, arg2, ..., argk)` | Invoke the mock function's `N`-th (0-based) argument, which must be a function or a functor, with the `k` arguments. |
+
+The return value of the invoked function is used as the return value of the
+action.
+
+When defining a callable to be used with `Invoke*()`, you can declare any unused
+parameters as `Unused`:
+
+```cpp
+using ::testing::Invoke;
+double Distance(Unused, double x, double y) { return sqrt(x*x + y*y); }
+...
+EXPECT_CALL(mock, Foo("Hi", _, _)).WillOnce(Invoke(Distance));
+```
+
+`Invoke(callback)` and `InvokeWithoutArgs(callback)` take ownership of
+`callback`, which must be permanent. The type of `callback` must be a base
+callback type instead of a derived one, e.g.
+
+```cpp
+ BlockingClosure* done = new BlockingClosure;
+ ... Invoke(done) ...; // This won't compile!
+
+ Closure* done2 = new BlockingClosure;
+ ... Invoke(done2) ...; // This works.
+```
+
+In `InvokeArgument<N>(...)`, if an argument needs to be passed by reference,
+wrap it inside `std::ref()`. For example,
+
+```cpp
+using ::testing::InvokeArgument;
+...
+InvokeArgument<2>(5, string("Hi"), std::ref(foo))
+```
+
+calls the mock function's #2 argument, passing to it `5` and `string("Hi")` by
+value, and `foo` by reference.
+
+## Default Action
+
+| Action | Description |
+| :------------ | :----------------------------------------------------- |
+| `DoDefault()` | Do the default action (specified by `ON_CALL()` or the built-in one). |
+
+{: .callout .note}
+**Note:** due to technical reasons, `DoDefault()` cannot be used inside a
+composite action - trying to do so will result in a run-time error.
+
+## Composite Actions
+
+| Action | Description |
+| :----------------------------- | :------------------------------------------ |
+| `DoAll(a1, a2, ..., an)` | Do all actions `a1` to `an` and return the result of `an` in each invocation. The first `n - 1` sub-actions must return void and will receive a readonly view of the arguments. |
+| `IgnoreResult(a)` | Perform action `a` and ignore its result. `a` must not return void. |
+| `WithArg<N>(a)` | Pass the `N`-th (0-based) argument of the mock function to action `a` and perform it. |
+| `WithArgs<N1, N2, ..., Nk>(a)` | Pass the selected (0-based) arguments of the mock function to action `a` and perform it. |
+| `WithoutArgs(a)` | Perform action `a` without any arguments. |
+
+## Defining Actions
+
+| Macro | Description |
+| :--------------------------------- | :-------------------------------------- |
+| `ACTION(Sum) { return arg0 + arg1; }` | Defines an action `Sum()` to return the sum of the mock function's argument #0 and #1. |
+| `ACTION_P(Plus, n) { return arg0 + n; }` | Defines an action `Plus(n)` to return the sum of the mock function's argument #0 and `n`. |
+| `ACTION_Pk(Foo, p1, ..., pk) { statements; }` | Defines a parameterized action `Foo(p1, ..., pk)` to execute the given `statements`. |
+
+The `ACTION*` macros cannot be used inside a function or class.

+# Assertions Reference
+
+This page lists the assertion macros provided by GoogleTest for verifying code
+behavior. To use them, include the header `gtest/gtest.h`.
+
+The majority of the macros listed below come as a pair with an `EXPECT_` variant
+and an `ASSERT_` variant. Upon failure, `EXPECT_` macros generate nonfatal
+failures and allow the current function to continue running, while `ASSERT_`
+macros generate fatal failures and abort the current function.
+
+All assertion macros support streaming a custom failure message into them with
+the `<<` operator, for example:
+
+```cpp
+EXPECT_TRUE(my_condition) << "My condition is not true";
+```
+
+Anything that can be streamed to an `ostream` can be streamed to an assertion
+macro—in particular, C strings and string objects. If a wide string (`wchar_t*`,
+`TCHAR*` in `UNICODE` mode on Windows, or `std::wstring`) is streamed to an
+assertion, it will be translated to UTF-8 when printed.
+
+## Explicit Success and Failure {#success-failure}
+
+The assertions in this section generate a success or failure directly instead of
+testing a value or expression. These are useful when control flow, rather than a
+Boolean expression, determines the test's success or failure, as shown by the
+following example:
+
+```c++
+switch(expression) {
+ case 1:
+ ... some checks ...
+ case 2:
+ ... some other checks ...
+ default:
+ FAIL() << "We shouldn't get here.";
+}
+```
+
+### SUCCEED {#SUCCEED}
+
+`SUCCEED()`
+
+Generates a success. This *does not* make the overall test succeed. A test is
+considered successful only if none of its assertions fail during its execution.
+
+The `SUCCEED` assertion is purely documentary and currently doesn't generate any
+user-visible output. However, we may add `SUCCEED` messages to GoogleTest output
+in the future.
+
+### FAIL {#FAIL}
+
+`FAIL()`
+
+Generates a fatal failure, which returns from the current function.
+
+Can only be used in functions that return `void`. See
+[Assertion Placement](../advanced.md#assertion-placement) for more information.
+
+### ADD_FAILURE {#ADD_FAILURE}
+
+`ADD_FAILURE()`
+
+Generates a nonfatal failure, which allows the current function to continue
+running.
+
+### ADD_FAILURE_AT {#ADD_FAILURE_AT}
+
+`ADD_FAILURE_AT(`*`file_path`*`,`*`line_number`*`)`
+
+Generates a nonfatal failure at the file and line number specified.
+
+## Generalized Assertion {#generalized}
+
+The following assertion allows [matchers](matchers.md) to be used to verify
+values.
+
+### EXPECT_THAT {#EXPECT_THAT}
+
+`EXPECT_THAT(`*`value`*`,`*`matcher`*`)` \
+`ASSERT_THAT(`*`value`*`,`*`matcher`*`)`
+
+Verifies that *`value`* matches the [matcher](matchers.md) *`matcher`*.
+
+For example, the following code verifies that the string `value1` starts with
+`"Hello"`, `value2` matches a regular expression, and `value3` is between 5 and
+10:
+
+```cpp
+#include "gmock/gmock.h"
+
+using ::testing::AllOf;
+using ::testing::Gt;
+using ::testing::Lt;
+using ::testing::MatchesRegex;
+using ::testing::StartsWith;
+
+...
+EXPECT_THAT(value1, StartsWith("Hello"));
+EXPECT_THAT(value2, MatchesRegex("Line \\d+"));
+ASSERT_THAT(value3, AllOf(Gt(5), Lt(10)));
+```
+
+Matchers enable assertions of this form to read like English and generate
+informative failure messages. For example, if the above assertion on `value1`
+fails, the resulting message will be similar to the following:
+
+```
+Value of: value1
+ Actual: "Hi, world!"
+Expected: starts with "Hello"
+```
+
+GoogleTest provides a built-in library of matchers—see the
+[Matchers Reference](matchers.md). It is also possible to write your own
+matchers—see [Writing New Matchers Quickly](../gmock_cook_book.md#NewMatchers).
+The use of matchers makes `EXPECT_THAT` a powerful, extensible assertion.
+
+*The idea for this assertion was borrowed from Joe Walnes' Hamcrest project,
+which adds `assertThat()` to JUnit.*
+
+## Boolean Conditions {#boolean}
+
+The following assertions test Boolean conditions.
+
+### EXPECT_TRUE {#EXPECT_TRUE}
+
+`EXPECT_TRUE(`*`condition`*`)` \
+`ASSERT_TRUE(`*`condition`*`)`
+
+Verifies that *`condition`* is true.
+
+### EXPECT_FALSE {#EXPECT_FALSE}
+
+`EXPECT_FALSE(`*`condition`*`)` \
+`ASSERT_FALSE(`*`condition`*`)`
+
+Verifies that *`condition`* is false.
+
+## Binary Comparison {#binary-comparison}
+
+The following assertions compare two values. The value arguments must be
+comparable by the assertion's comparison operator, otherwise a compiler error
+will result.
+
+If an argument supports the `<<` operator, it will be called to print the
+argument when the assertion fails. Otherwise, GoogleTest will attempt to print
+them in the best way it can—see
+[Teaching GoogleTest How to Print Your Values](../advanced.md#teaching-googletest-how-to-print-your-values).
+
+Arguments are always evaluated exactly once, so it's OK for the arguments to
+have side effects. However, the argument evaluation order is undefined and
+programs should not depend on any particular argument evaluation order.
+
+These assertions work with both narrow and wide string objects (`string` and
+`wstring`).
+
+See also the [Floating-Point Comparison](#floating-point) assertions to compare
+floating-point numbers and avoid problems caused by rounding.
+
+### EXPECT_EQ {#EXPECT_EQ}
+
+`EXPECT_EQ(`*`val1`*`,`*`val2`*`)` \
+`ASSERT_EQ(`*`val1`*`,`*`val2`*`)`
+
+Verifies that *`val1`*`==`*`val2`*.
+
+Does pointer equality on pointers. If used on two C strings, it tests if they
+are in the same memory location, not if they have the same value. Use
+[`EXPECT_STREQ`](#EXPECT_STREQ) to compare C strings (e.g. `const char*`) by
+value.
+
+When comparing a pointer to `NULL`, use `EXPECT_EQ(`*`ptr`*`, nullptr)` instead
+of `EXPECT_EQ(`*`ptr`*`, NULL)`.
+
+### EXPECT_NE {#EXPECT_NE}
+
+`EXPECT_NE(`*`val1`*`,`*`val2`*`)` \
+`ASSERT_NE(`*`val1`*`,`*`val2`*`)`
+
+Verifies that *`val1`*`!=`*`val2`*.
+
+Does pointer equality on pointers. If used on two C strings, it tests if they
+are in different memory locations, not if they have different values. Use
+[`EXPECT_STRNE`](#EXPECT_STRNE) to compare C strings (e.g. `const char*`) by
+value.
+
+When comparing a pointer to `NULL`, use `EXPECT_NE(`*`ptr`*`, nullptr)` instead
+of `EXPECT_NE(`*`ptr`*`, NULL)`.
+
+### EXPECT_LT {#EXPECT_LT}
+
+`EXPECT_LT(`*`val1`*`,`*`val2`*`)` \
+`ASSERT_LT(`*`val1`*`,`*`val2`*`)`
+
+Verifies that *`val1`*`<`*`val2`*.
+
+### EXPECT_LE {#EXPECT_LE}
+
+`EXPECT_LE(`*`val1`*`,`*`val2`*`)` \
+`ASSERT_LE(`*`val1`*`,`*`val2`*`)`
+
+Verifies that *`val1`*`<=`*`val2`*.
+
+### EXPECT_GT {#EXPECT_GT}
+
+`EXPECT_GT(`*`val1`*`,`*`val2`*`)` \
+`ASSERT_GT(`*`val1`*`,`*`val2`*`)`
+
+Verifies that *`val1`*`>`*`val2`*.
+
+### EXPECT_GE {#EXPECT_GE}
+
+`EXPECT_GE(`*`val1`*`,`*`val2`*`)` \
+`ASSERT_GE(`*`val1`*`,`*`val2`*`)`
+
+Verifies that *`val1`*`>=`*`val2`*.
+
+## String Comparison {#c-strings}
+
+The following assertions compare two **C strings**. To compare two `string`
+objects, use [`EXPECT_EQ`](#EXPECT_EQ) or [`EXPECT_NE`](#EXPECT_NE) instead.
+
+These assertions also accept wide C strings (`wchar_t*`). If a comparison of two
+wide strings fails, their values will be printed as UTF-8 narrow strings.
+
+To compare a C string with `NULL`, use `EXPECT_EQ(`*`c_string`*`, nullptr)` or
+`EXPECT_NE(`*`c_string`*`, nullptr)`.
+
+### EXPECT_STREQ {#EXPECT_STREQ}
+
+`EXPECT_STREQ(`*`str1`*`,`*`str2`*`)` \
+`ASSERT_STREQ(`*`str1`*`,`*`str2`*`)`
+
+Verifies that the two C strings *`str1`* and *`str2`* have the same contents.
+
+### EXPECT_STRNE {#EXPECT_STRNE}
+
+`EXPECT_STRNE(`*`str1`*`,`*`str2`*`)` \
+`ASSERT_STRNE(`*`str1`*`,`*`str2`*`)`
+
+Verifies that the two C strings *`str1`* and *`str2`* have different contents.
+
+### EXPECT_STRCASEEQ {#EXPECT_STRCASEEQ}
+
+`EXPECT_STRCASEEQ(`*`str1`*`,`*`str2`*`)` \
+`ASSERT_STRCASEEQ(`*`str1`*`,`*`str2`*`)`
+
+Verifies that the two C strings *`str1`* and *`str2`* have the same contents,
+ignoring case.
+
+### EXPECT_STRCASENE {#EXPECT_STRCASENE}
+
+`EXPECT_STRCASENE(`*`str1`*`,`*`str2`*`)` \
+`ASSERT_STRCASENE(`*`str1`*`,`*`str2`*`)`
+
+Verifies that the two C strings *`str1`* and *`str2`* have different contents,
+ignoring case.
+
+## Floating-Point Comparison {#floating-point}
+
+The following assertions compare two floating-point values.
+
+Due to rounding errors, it is very unlikely that two floating-point values will
+match exactly, so `EXPECT_EQ` is not suitable. In general, for floating-point
+comparison to make sense, the user needs to carefully choose the error bound.
+
+GoogleTest also provides assertions that use a default error bound based on
+Units in the Last Place (ULPs). To learn more about ULPs, see the article
+[Comparing Floating Point Numbers](https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/).
+
+### EXPECT_FLOAT_EQ {#EXPECT_FLOAT_EQ}
+
+`EXPECT_FLOAT_EQ(`*`val1`*`,`*`val2`*`)` \
+`ASSERT_FLOAT_EQ(`*`val1`*`,`*`val2`*`)`
+
+Verifies that the two `float` values *`val1`* and *`val2`* are approximately
+equal, to within 4 ULPs from each other.
+
+### EXPECT_DOUBLE_EQ {#EXPECT_DOUBLE_EQ}
+
+`EXPECT_DOUBLE_EQ(`*`val1`*`,`*`val2`*`)` \
+`ASSERT_DOUBLE_EQ(`*`val1`*`,`*`val2`*`)`
+
+Verifies that the two `double` values *`val1`* and *`val2`* are approximately
+equal, to within 4 ULPs from each other.
+
+### EXPECT_NEAR {#EXPECT_NEAR}
+
+`EXPECT_NEAR(`*`val1`*`,`*`val2`*`,`*`abs_error`*`)` \
+`ASSERT_NEAR(`*`val1`*`,`*`val2`*`,`*`abs_error`*`)`
+
+Verifies that the difference between *`val1`* and *`val2`* does not exceed the
+absolute error bound *`abs_error`*.
+
+## Exception Assertions {#exceptions}
+
+The following assertions verify that a piece of code throws, or does not throw,
+an exception. Usage requires exceptions to be enabled in the build environment.
+
+Note that the piece of code under test can be a compound statement, for example:
+
+```cpp
+EXPECT_NO_THROW({
+ int n = 5;
+ DoSomething(&n);
+});
+```
+
+### EXPECT_THROW {#EXPECT_THROW}
+
+`EXPECT_THROW(`*`statement`*`,`*`exception_type`*`)` \
+`ASSERT_THROW(`*`statement`*`,`*`exception_type`*`)`
+
+Verifies that *`statement`* throws an exception of type *`exception_type`*.
+
+### EXPECT_ANY_THROW {#EXPECT_ANY_THROW}
+
+`EXPECT_ANY_THROW(`*`statement`*`)` \
+`ASSERT_ANY_THROW(`*`statement`*`)`
+
+Verifies that *`statement`* throws an exception of any type.
+
+### EXPECT_NO_THROW {#EXPECT_NO_THROW}
+
+`EXPECT_NO_THROW(`*`statement`*`)` \
+`ASSERT_NO_THROW(`*`statement`*`)`
+
+Verifies that *`statement`* does not throw any exception.
+
+## Predicate Assertions {#predicates}
+
+The following assertions enable more complex predicates to be verified while
+printing a more clear failure message than if `EXPECT_TRUE` were used alone.
+
+### EXPECT_PRED* {#EXPECT_PRED}
+
+`EXPECT_PRED1(`*`pred`*`,`*`val1`*`)` \
+`EXPECT_PRED2(`*`pred`*`,`*`val1`*`,`*`val2`*`)` \
+`EXPECT_PRED3(`*`pred`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`)` \
+`EXPECT_PRED4(`*`pred`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`,`*`val4`*`)` \
+`EXPECT_PRED5(`*`pred`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`,`*`val4`*`,`*`val5`*`)`
+
+`ASSERT_PRED1(`*`pred`*`,`*`val1`*`)` \
+`ASSERT_PRED2(`*`pred`*`,`*`val1`*`,`*`val2`*`)` \
+`ASSERT_PRED3(`*`pred`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`)` \
+`ASSERT_PRED4(`*`pred`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`,`*`val4`*`)` \
+`ASSERT_PRED5(`*`pred`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`,`*`val4`*`,`*`val5`*`)`
+
+Verifies that the predicate *`pred`* returns `true` when passed the given values
+as arguments.
+
+The parameter *`pred`* is a function or functor that accepts as many arguments
+as the corresponding macro accepts values. If *`pred`* returns `true` for the
+given arguments, the assertion succeeds, otherwise the assertion fails.
+
+When the assertion fails, it prints the value of each argument. Arguments are
+always evaluated exactly once.
+
+As an example, see the following code:
+
+```cpp
+// Returns true if m and n have no common divisors except 1.
+bool MutuallyPrime(int m, int n) { ... }
+...
+const int a = 3;
+const int b = 4;
+const int c = 10;
+...
+EXPECT_PRED2(MutuallyPrime, a, b); // Succeeds
+EXPECT_PRED2(MutuallyPrime, b, c); // Fails
+```
+
+In the above example, the first assertion succeeds, and the second fails with
+the following message:
+
+```
+MutuallyPrime(b, c) is false, where
+b is 4
+c is 10
+```
+
+Note that if the given predicate is an overloaded function or a function
+template, the assertion macro might not be able to determine which version to
+use, and it might be necessary to explicitly specify the type of the function.
+For example, for a Boolean function `IsPositive()` overloaded to take either a
+single `int` or `double` argument, it would be necessary to write one of the
+following:
+
+```cpp
+EXPECT_PRED1(static_cast<bool (*)(int)>(IsPositive), 5);
+EXPECT_PRED1(static_cast<bool (*)(double)>(IsPositive), 3.14);
+```
+
+Writing simply `EXPECT_PRED1(IsPositive, 5);` would result in a compiler error.
+Similarly, to use a template function, specify the template arguments:
+
+```cpp
+template <typename T>
+bool IsNegative(T x) {
+ return x < 0;
+}
+...
+EXPECT_PRED1(IsNegative<int>, -5); // Must specify type for IsNegative
+```
+
+If a template has multiple parameters, wrap the predicate in parentheses so the
+macro arguments are parsed correctly:
+
+```cpp
+ASSERT_PRED2((MyPredicate<int, int>), 5, 0);
+```

+\
+`ASSERT_PRED_FORMAT5(`*`pred_formatter`*`,`*`val1`*`,`*`val2`*`,`*`val3`*`,`*`val4`*`,`*`val5`*`)`
+
+Verifies that the predicate *`pred_formatter`* succeeds when passed the given
+values as arguments.
+
+The parameter *`pred_formatter`* is a *predicate-formatter*, which is a function
+or functor with the signature:
+
+```cpp
+testing::AssertionResult PredicateFormatter(const char* expr1,
+ const char* expr2,
+ ...
+ const char* exprn,
+ T1 val1,
+ T2 val2,
+ ...
+ Tn valn);
+```
+
+where *`val1`*, *`val2`*, ..., *`valn`* are the values of the predicate
+arguments, and *`expr1`*, *`expr2`*, ..., *`exprn`* are the corresponding
+expressions as they appear in the source code. The types `T1`, `T2`, ..., `Tn`
+can be either value types or reference types; if an argument has type `T`, it
+can be declared as either `T` or `const T&`, whichever is appropriate. For more
+about the return type `testing::AssertionResult`, see
+[Using a Function That Returns an AssertionResult](../advanced.md#using-a-function-that-returns-an-assertionresult).
+
+As an example, see the following code:
+
+```cpp
+// Returns the smallest prime common divisor of m and n,
+// or 1 when m and n are mutually prime.
+int SmallestPrimeCommonDivisor(int m, int n) { ... }
+
+// Returns true if m and n have no common divisors except 1.
+bool MutuallyPrime(int m, int n) { ... }
+
+// A predicate-formatter for asserting that two integers are mutually prime.
+testing::AssertionResult AssertMutuallyPrime(const char* m_expr,
+ const char* n_expr,
+ int m,
+ int n) {
+ if (MutuallyPrime(m, n)) return testing::AssertionSuccess();
+
+ return testing::AssertionFailure() << m_expr << " and " << n_expr
+ << " (" << m << " and " << n << ") are not mutually prime, "
+ << "as they have a common divisor " << SmallestPrimeCommonDivisor(m, n);
+}
+
+...
+const int a = 3;
+const int b = 4;
+const int c = 10;
+...
+EXPECT_PRED_FORMAT2(AssertMutuallyPrime, a, b); // Succeeds
+EXPECT_PRED_FORMAT2(AssertMutuallyPrime, b, c); // Fails
+```
+
+In the above example, the final assertion fails and the predicate-formatter
+produces the following failure message:
+
+```
+b and c (4 and 10) are not mutually prime, as they have a common divisor 2
+```
+
+## Windows HRESULT Assertions {#HRESULT}
+
+The following assertions test for `HRESULT` success or failure. For example:
+
+```cpp
+CComPtr<IShellDispatch2> shell;
+ASSERT_HRESULT_SUCCEEDED(shell.CoCreateInstance(L"Shell.Application"));
+CComVariant empty;
+ASSERT_HRESULT_SUCCEEDED(shell->ShellExecute(CComBSTR(url), empty, empty, empty, empty));
+```
+
+The generated output contains the human-readable error message associated with
+the returned `HRESULT` code.
+
+### EXPECT_HRESULT_SUCCEEDED {#EXPECT_HRESULT_SUCCEEDED}
+
+`EXPECT_HRESULT_SUCCEEDED(`*`expression`*`)` \
+`ASSERT_HRESULT_SUCCEEDED(`*`expression`*`)`
+
+Verifies that *`expression`* is a success `HRESULT`.
+
+### EXPECT_HRESULT_FAILED {#EXPECT_HRESULT_FAILED}
+
+`EXPECT_HRESULT_FAILED(`*`expression`*`)` \
+`EXPECT_HRESULT_FAILED(`*`expression`*`)`
+
+Verifies that *`expression`* is a failure `HRESULT`.
+
+## Death Assertions {#death}
+
+The following assertions verify that a piece of code causes the process to
+terminate. For context, see [Death Tests](../advanced.md#death-tests).
+
+These assertions spawn a new process and execute the code under test in that
+process. How that happens depends on the platform and the variable
+`::testing::GTEST_FLAG(death_test_style)`, which is initialized from the
+command-line flag `--gtest_death_test_style`.
+
+* On POSIX systems, `fork()` (or `clone()` on Linux) is used to spawn the
+ child, after which:
+ * If the variable's value is `"fast"`, the death test statement is
+ immediately executed.
+ * If the variable's value is `"threadsafe"`, the child process re-executes
+ the unit test binary just as it was originally invoked, but with some
+ extra flags to cause just the single death test under consideration to
+ be run.
+* On Windows, the child is spawned using the `CreateProcess()` API, and
+ re-executes the binary to cause just the single death test under
+ consideration to be run - much like the `"threadsafe"` mode on POSIX.
+
+Other values for the variable are illegal and will cause the death test to fail.
+Currently, the flag's default value is
+**`"fast"`**.
+
+If the death test statement runs to completion without dying, the child process
+will nonetheless terminate, and the assertion fails.
+
+Note that the piece of code under test can be a compound statement, for example:
+
+```cpp
+EXPECT_DEATH({
+ int n = 5;
+ DoSomething(&n);
+}, "Error on line .* of DoSomething()");
+```
+
+### EXPECT_DEATH {#EXPECT_DEATH}
+
+`EXPECT_DEATH(`*`statement`*`,`*`matcher`*`)` \
+`ASSERT_DEATH(`*`statement`*`,`*`matcher`*`)`
+
+Verifies that *`statement`* causes the process to terminate with a nonzero exit
+status and produces `stderr` output that matches *`matcher`*.
+
+The parameter *`matcher`* is either a [matcher](matchers.md) for a `const
+std::string&`, or a regular expression (see
+[Regular Expression Syntax](../advanced.md#regular-expression-syntax))—a bare
+string *`s`* (with no matcher) is treated as
+[`ContainsRegex(s)`](matchers.md#string-matchers), **not**
+[`Eq(s)`](matchers.md#generic-comparison).
+
+For example, the following code verifies that calling `DoSomething(42)` causes
+the process to die with an error message that contains the text `My error`:
+
+```cpp
+EXPECT_DEATH(DoSomething(42), "My error");
+```
+
+### EXPECT_DEATH_IF_SUPPORTED {#EXPECT_DEATH_IF_SUPPORTED}
+
+`EXPECT_DEATH_IF_SUPPORTED(`*`statement`*`,`*`matcher`*`)` \
+`ASSERT_DEATH_IF_SUPPORTED(`*`statement`*`,`*`matcher`*`)`
+
+If death tests are supported, behaves the same as
+[`EXPECT_DEATH`](#EXPECT_DEATH). Otherwise, verifies nothing.
+
+### EXPECT_DEBUG_DEATH {#EXPECT_DEBUG_DEATH}
+
+`EXPECT_DEBUG_DEATH(`*`statement`*`,`*`matcher`*`)` \
+`ASSERT_DEBUG_DEATH(`*`statement`*`,`*`matcher`*`)`
+
+In debug mode, behaves the same as [`EXPECT_DEATH`](#EXPECT_DEATH). When not in
+debug mode (i.e. `NDEBUG` is defined), just executes *`statement`*.
+
+### EXPECT_EXIT {#EXPECT_EXIT}
+
+`EXPECT_EXIT(`*`statement`*`,`*`predicate`*`,`*`matcher`*`)` \
+`ASSERT_EXIT(`*`statement`*`,`*`predicate`*`,`*`matcher`*`)`
+
+Verifies that *`statement`* causes the process to terminate with an exit status
+that satisfies *`predicate`*, and produces `stderr` output that matches
+*`matcher`*.
+
+The parameter *`predicate`* is a function or functor that accepts an `int` exit
+status and returns a `bool`. GoogleTest provides two predicates to handle common
+cases:
+
+```cpp
+// Returns true if the program exited normally with the given exit status code.
+::testing::ExitedWithCode(exit_code);
+
+// Returns true if the program was killed by the given signal.
+// Not available on Windows.
+::testing::KilledBySignal(signal_number);
+```
+
+The parameter *`matcher`* is either a [matcher](matchers.md) for a `const
+std::string&`, or a regular expression (see
+[Regular Expression Syntax](../advanced.md#regular-expression-syntax))—a bare
+string *`s`* (with no matcher) is treated as
+[`ContainsRegex(s)`](matchers.md#string-matchers), **not**
+[`Eq(s)`](matchers.md#generic-comparison).
+
+For example, the following code verifies that calling `NormalExit()` causes the
+process to print a message containing the text `Success` to `stderr` and exit
+with exit status code 0:
+
+```cpp
+EXPECT_EXIT(NormalExit(), testing::ExitedWithCode(0), "Success");
+```

+# Matchers Reference
+
+A **matcher** matches a *single* argument. You can use it inside `ON_CALL()` or
+`EXPECT_CALL()`, or use it to validate a value directly using two macros:
+
+| Macro | Description |
+| :----------------------------------- | :------------------------------------ |
+| `EXPECT_THAT(actual_value, matcher)` | Asserts that `actual_value` matches `matcher`. |
+| `ASSERT_THAT(actual_value, matcher)` | The same as `EXPECT_THAT(actual_value, matcher)`, except that it generates a **fatal** failure. |
+
+{: .callout .note}
+**Note:** Although equality matching via `EXPECT_THAT(actual_value,
+expected_value)` is supported, prefer to make the comparison explicit via
+`EXPECT_THAT(actual_value, Eq(expected_value))` or `EXPECT_EQ(actual_value,
+expected_value)`.
+
+Built-in matchers (where `argument` is the function argument, e.g.
+`actual_value` in the example above, or when used in the context of
+`EXPECT_CALL(mock_object, method(matchers))`, the arguments of `method`) are
+divided into several categories. All matchers are defined in the `::testing`
+namespace unless otherwise noted.
+
+## Wildcard
+
+Matcher | Description
+:-------------------------- | :-----------------------------------------------
+`_` | `argument` can be any value of the correct type.
+`A<type>()` or `An<type>()` | `argument` can be any value of type `type`.
+
+## Generic Comparison
+
+| Matcher | Description |
+| :--------------------- | :-------------------------------------------------- |
+| `Eq(value)` or `value` | `argument == value` |
+| `Ge(value)` | `argument >= value` |
+| `Gt(value)` | `argument > value` |
+| `Le(value)` | `argument <= value` |
+| `Lt(value)` | `argument < value` |
+| `Ne(value)` | `argument != value` |
+| `IsFalse()` | `argument` evaluates to `false` in a Boolean context. |
+| `IsTrue()` | `argument` evaluates to `true` in a Boolean context. |
+| `IsNull()` | `argument` is a `NULL` pointer (raw or smart). |
+| `NotNull()` | `argument` is a non-null pointer (raw or smart). |
+| `Optional(m)` | `argument` is `optional<>` that contains a value matching `m`. (For testing whether an `optional<>` is set, check for equality with `nullopt`. You may need to use `Eq(nullopt)` if the inner type doesn't have `==`.)|
+| `VariantWith<T>(m)` | `argument` is `variant<>` that holds the alternative of type T with a value matching `m`. |
+| `Ref(variable)` | `argument` is a reference to `variable`. |
+| `TypedEq<type>(value)` | `argument` has type `type` and is equal to `value`. You may need to use this instead of `Eq(value)` when the mock function is overloaded. |
+
+Except `Ref()`, these matchers make a *copy* of `value` in case it's modified or
+destructed later. If the compiler complains that `value` doesn't have a public
+copy constructor, try wrap it in `std::ref()`, e.g.
+`Eq(std::ref(non_copyable_value))`. If you do that, make sure
+`non_copyable_value` is not changed afterwards, or the meaning of your matcher
+will be changed.
+
+`IsTrue` and `IsFalse` are useful when you need to use a matcher, or for types
+that can be explicitly converted to Boolean, but are not implicitly converted to
+Boolean. In other cases, you can use the basic
+[`EXPECT_TRUE` and `EXPECT_FALSE`](assertions.md#boolean) assertions.
+
+## Floating-Point Matchers {#FpMatchers}
+
+| Matcher | Description |
+| :------------------------------- | :--------------------------------- |
+| `DoubleEq(a_double)` | `argument` is a `double` value approximately equal to `a_double`, treating two NaNs as unequal. |
+| `FloatEq(a_float)` | `argument` is a `float` value approximately equal to `a_float`, treating two NaNs as unequal. |
+| `NanSensitiveDoubleEq(a_double)` | `argument` is a `double` value approximately equal to `a_double`, treating two NaNs as equal. |
+| `NanSensitiveFloatEq(a_float)` | `argument` is a `float` value approximately equal to `a_float`, treating two NaNs as equal. |
+| `IsNan()` | `argument` is any floating-point type with a NaN value. |
+
+The above matchers use ULP-based comparison (the same as used in googletest).
+They automatically pick a reasonable error bound based on the absolute value of
+the expected value. `DoubleEq()` and `FloatEq()` conform to the IEEE standard,
+which requires comparing two NaNs for equality to return false. The
+`NanSensitive*` version instead treats two NaNs as equal, which is often what a
+user wants.
+
+| Matcher | Description |
+| :------------------------------------------------ | :----------------------- |
+| `DoubleNear(a_double, max_abs_error)` | `argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
+| `FloatNear(a_float, max_abs_error)` | `argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
+| `NanSensitiveDoubleNear(a_double, max_abs_error)` | `argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
+| `NanSensitiveFloatNear(a_float, max_abs_error)` | `argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
+
+## String Matchers
+
+The `argument` can be either a C string or a C++ string object:
+
+| Matcher | Description |
+| :---------------------- | :------------------------------------------------- |
+| `ContainsRegex(string)` | `argument` matches the given regular expression. |
+| `EndsWith(suffix)` | `argument` ends with string `suffix`. |
+| `HasSubstr(string)` | `argument` contains `string` as a sub-string. |
+| `IsEmpty()` | `argument` is an empty string. |
+| `MatchesRegex(string)` | `argument` matches the given regular expression with the match starting at the first character and ending at the last character. |
+| `StartsWith(prefix)` | `argument` starts with string `prefix`. |
+| `StrCaseEq(string)` | `argument` is equal to `string`, ignoring case. |
+| `StrCaseNe(string)` | `argument` is not equal to `string`, ignoring case. |
+| `StrEq(string)` | `argument` is equal to `string`. |
+| `StrNe(string)` | `argument` is not equal to `string`. |
+| `WhenBase64Unescaped(m)` | `argument` is a base-64 escaped string whose unescaped string matches `m`. |
+
+`ContainsRegex()` and `MatchesRegex()` take ownership of the `RE` object. They
+use the regular expression syntax defined
+[here](../advanced.md#regular-expression-syntax). All of these matchers, except
+`ContainsRegex()` and `MatchesRegex()` work for wide strings as well.
+
+## Container Matchers
+
+Most STL-style containers support `==`, so you can use `Eq(expected_container)`
+or simply `expected_container` to match a container exactly. If you want to
+write the elements in-line, match them more flexibly, or get more informative
+messages, you can use:
+
+| Matcher | Description |
+| :---------------------------------------- | :------------------------------- |
+| `BeginEndDistanceIs(m)` | `argument` is a container whose `begin()` and `end()` iterators are separated by a number of increments matching `m`. E.g. `BeginEndDistanceIs(2)` or `BeginEndDistanceIs(Lt(2))`. For containers that define a `size()` method, `SizeIs(m)` may be more efficient. |
+| `ContainerEq(container)` | The same as `Eq(container)` except that the failure message also includes which elements are in one container but not the other. |
+| `Contains(e)` | `argument` contains an element that matches `e`, which can be either a value or a matcher. |
+| `Contains(e).Times(n)` | `argument` contains elements that match `e`, which can be either a value or a matcher, and the number of matches is `n`, which can be either a value or a matcher. Unlike the plain `Contains` and `Each` this allows to check for arbitrary occurrences including testing for absence with `Contains(e).Times(0)`. |
+| `Each(e)` | `argument` is a container where *every* element matches `e`, which can be either a value or a matcher. |
+| `ElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, where the *i*-th element matches `ei`, which can be a value or a matcher. |
+| `ElementsAreArray({e0, e1, ..., en})`, `ElementsAreArray(a_container)`, `ElementsAreArray(begin, end)`, `ElementsAreArray(array)`, or `ElementsAreArray(array, count)` | The same as `ElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
+| `IsEmpty()` | `argument` is an empty container (`container.empty()`). |
+| `IsSubsetOf({e0, e1, ..., en})`, `IsSubsetOf(a_container)`, `IsSubsetOf(begin, end)`, `IsSubsetOf(array)`, or `IsSubsetOf(array, count)` | `argument` matches `UnorderedElementsAre(x0, x1, ..., xk)` for some subset `{x0, x1, ..., xk}` of the expected matchers. |
+| `IsSupersetOf({e0, e1, ..., en})`, `IsSupersetOf(a_container)`, `IsSupersetOf(begin, end)`, `IsSupersetOf(array)`, or `IsSupersetOf(array, count)` | Some subset of `argument` matches `UnorderedElementsAre(`expected matchers`)`. |
+| `Pointwise(m, container)`, `Pointwise(m, {e0, e1, ..., en})` | `argument` contains the same number of elements as in `container`, and for all i, (the i-th element in `argument`, the i-th element in `container`) match `m`, which is a matcher on 2-tuples. E.g. `Pointwise(Le(), upper_bounds)` verifies that each element in `argument` doesn't exceed the corresponding element in `upper_bounds`. See more detail below. |
+| `SizeIs(m)` | `argument` is a container whose size matches `m`. E.g. `SizeIs(2)` or `SizeIs(Lt(2))`. |
+| `UnorderedElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, and under *some* permutation of the elements, each element matches an `ei` (for a different `i`), which can be a value or a matcher. |
+| `UnorderedElementsAreArray({e0, e1, ..., en})`, `UnorderedElementsAreArray(a_container)`, `UnorderedElementsAreArray(begin, end)`, `UnorderedElementsAreArray(array)`, or `UnorderedElementsAreArray(array, count)` | The same as `UnorderedElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
+| `UnorderedPointwise(m, container)`, `UnorderedPointwise(m, {e0, e1, ..., en})` | Like `Pointwise(m, container)`, but ignores the order of elements. |
+| `WhenSorted(m)` | When `argument` is sorted using the `<` operator, it matches container matcher `m`. E.g. `WhenSorted(ElementsAre(1, 2, 3))` verifies that `argument` contains elements 1, 2, and 3, ignoring order. |
+| `WhenSortedBy(comparator, m)` | The same as `WhenSorted(m)`, except that the given comparator instead of `<` is used to sort `argument`. E.g. `WhenSortedBy(std::greater(), ElementsAre(3, 2, 1))`. |
+
+**Notes:**
+
+* These matchers can also match:
+ 1. a native array passed by reference (e.g. in `Foo(const int (&a)[5])`),
+ and
+ 2. an array passed as a pointer and a count (e.g. in `Bar(const T* buffer,
+ int len)` -- see [Multi-argument Matchers](#MultiArgMatchers)).
+* The array being matched may be multi-dimensional (i.e. its elements can be
+ arrays).
+* `m` in `Pointwise(m, ...)` and `UnorderedPointwise(m, ...)` should be a
+ matcher for `::std::tuple<T, U>` where `T` and `U` are the element type of
+ the actual container and the expected container, respectively. For example,
+ to compare two `Foo` containers where `Foo` doesn't support `operator==`,
+ one might write:
+
+ ```cpp
+ MATCHER(FooEq, "") {
+ return std::get<0>(arg).Equals(std::get<1>(arg));
+ }
+ ...
+ EXPECT_THAT(actual_foos, Pointwise(FooEq(), expected_foos));
+ ```
+
+## Member Matchers
+
+| Matcher | Description |
+| :------------------------------ | :----------------------------------------- |
+| `Field(&class::field, m)` | `argument.field` (or `argument->field` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_. |
+| `Field(field_name, &class::field, m)` | The same as the two-parameter version, but provides a better error message. |
+| `Key(e)` | `argument.first` matches `e`, which can be either a value or a matcher. E.g. `Contains(Key(Le(5)))` can verify that a `map` contains a key `<= 5`. |
+| `Pair(m1, m2)` | `argument` is an `std::pair` whose `first` field matches `m1` and `second` field matches `m2`. |
+| `FieldsAre(m...)` | `argument` is a compatible object where each field matches piecewise with the matchers `m...`. A compatible object is any that supports the `std::tuple_size<Obj>`+`get<I>(obj)` protocol. In C++17 and up this also supports types compatible with structured bindings, like aggregates. |
+| `Property(&class::property, m)` | `argument.property()` (or `argument->property()` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_. The method `property()` must take no argument and be declared as `const`. |
+| `Property(property_name, &class::property, m)` | The same as the two-parameter version, but provides a better error message.
+
+**Notes:**
+
+* You can use `FieldsAre()` to match any type that supports structured
+ bindings, such as `std::tuple`, `std::pair`, `std::array`, and aggregate
+ types. For example:
+
+ ```cpp
+ std::tuple<int, std::string> my_tuple{7, "hello world"};
+ EXPECT_THAT(my_tuple, FieldsAre(Ge(0), HasSubstr("hello")));
+
+ struct MyStruct {
+ int value = 42;
+ std::string greeting = "aloha";
+ };
+ MyStruct s;
+ EXPECT_THAT(s, FieldsAre(42, "aloha"));
+ ```
+
+* Don't use `Property()` against member functions that you do not own, because
+ taking addresses of functions is fragile and generally not part of the
+ contract of the function.
+
+## Matching the Result of a Function, Functor, or Callback
+
+| Matcher | Description |
+| :--------------- | :------------------------------------------------ |
+| `ResultOf(f, m)` | `f(argument)` matches matcher `m`, where `f` is a function or functor. |
+
+## Pointer Matchers
+
+| Matcher | Description |
+| :------------------------ | :---------------------------------------------- |
+| `Address(m)` | the result of `std::addressof(argument)` matches `m`. |
+| `Pointee(m)` | `argument` (either a smart pointer or a raw pointer) points to a value that matches matcher `m`. |
+| `Pointer(m)` | `argument` (either a smart pointer or a raw pointer) contains a pointer that matches `m`. `m` will match against the raw pointer regardless of the type of `argument`. |
+| `WhenDynamicCastTo<T>(m)` | when `argument` is passed through `dynamic_cast<T>()`, it matches matcher `m`. |
+
+## Multi-argument Matchers {#MultiArgMatchers}
+
+Technically, all matchers match a *single* value. A "multi-argument" matcher is
+just one that matches a *tuple*. The following matchers can be used to match a
+tuple `(x, y)`:
+
+Matcher | Description
+:------ | :----------
+`Eq()` | `x == y`
+`Ge()` | `x >= y`
+`Gt()` | `x > y`
+`Le()` | `x <= y`
+`Lt()` | `x < y`
+`Ne()` | `x != y`
+
+You can use the following selectors to pick a subset of the arguments (or
+reorder them) to participate in the matching:
+
+| Matcher | Description |
+| :------------------------- | :---------------------------------------------- |
+| `AllArgs(m)` | Equivalent to `m`. Useful as syntactic sugar in `.With(AllArgs(m))`. |
+| `Args<N1, N2, ..., Nk>(m)` | The tuple of the `k` selected (using 0-based indices) arguments matches `m`, e.g. `Args<1, 2>(Eq())`. |
+
+## Composite Matchers
+
+You can make a matcher from one or more other matchers:
+
+| Matcher | Description |
+| :------------------------------- | :-------------------------------------- |
+| `AllOf(m1, m2, ..., mn)` | `argument` matches all of the matchers `m1` to `mn`. |
+| `AllOfArray({m0, m1, ..., mn})`, `AllOfArray(a_container)`, `AllOfArray(begin, end)`, `AllOfArray(array)`, or `AllOfArray(array, count)` | The same as `AllOf()` except that the matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
+| `AnyOf(m1, m2, ..., mn)` | `argument` matches at least one of the matchers `m1` to `mn`. |
+| `AnyOfArray({m0, m1, ..., mn})`, `AnyOfArray(a_container)`, `AnyOfArray(begin, end)`, `AnyOfArray(array)`, or `AnyOfArray(array, count)` | The same as `AnyOf()` except that the matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
+| `Not(m)` | `argument` doesn't match matcher `m`. |
+| `Conditional(cond, m1, m2)` | Matches matcher `m1` if `cond` evaluates to true, else matches `m2`.|
+
+## Adapters for Matchers
+
+| Matcher | Description |
+| :---------------------- | :------------------------------------ |
+| `MatcherCast<T>(m)` | casts matcher `m` to type `Matcher<T>`. |
+| `SafeMatcherCast<T>(m)` | [safely casts](../gmock_cook_book.md#SafeMatcherCast) matcher `m` to type `Matcher<T>`. |
+| `Truly(predicate)` | `predicate(argument)` returns something considered by C++ to be true, where `predicate` is a function or functor. |
+
+`AddressSatisfies(callback)` and `Truly(callback)` take ownership of `callback`,
+which must be a permanent callback.
+
+## Using Matchers as Predicates {#MatchersAsPredicatesCheat}
+
+| Matcher | Description |
+| :---------------------------- | :------------------------------------------ |
+| `Matches(m)(value)` | evaluates to `true` if `value` matches `m`. You can use `Matches(m)` alone as a unary functor. |
+| `ExplainMatchResult(m, value, result_listener)` | evaluates to `true` if `value` matches `m`, explaining the result to `result_listener`. |
+| `Value(value, m)` | evaluates to `true` if `value` matches `m`. |
+
+## Defining Matchers
+
+| Macro | Description |
+| :----------------------------------- | :------------------------------------ |
+| `MATCHER(IsEven, "") { return (arg % 2) == 0; }` | Defines a matcher `IsEven()` to match an even number. |
+| `MATCHER_P(IsDivisibleBy, n, "") { *result_listener << "where the remainder is " << (arg % n); return (arg % n) == 0; }` | Defines a matcher `IsDivisibleBy(n)` to match a number divisible by `n`. |
+| `MATCHER_P2(IsBetween, a, b, absl::StrCat(negation ? "isn't" : "is", " between ", PrintToString(a), " and ", PrintToString(b))) { return a <= arg && arg <= b; }` | Defines a matcher `IsBetween(a, b)` to match a value in the range [`a`, `b`]. |
+
+**Notes:**
+
+1. The `MATCHER*` macros cannot be used inside a function or class.
+2. The matcher body must be *purely functional* (i.e. it cannot have any side
+ effect, and the result must not depend on anything other than the value
+ being matched and the matcher parameters).
+3. You can use `PrintToString(x)` to convert a value `x` of any type to a
+ string.
+4. You can use `ExplainMatchResult()` in a custom matcher to wrap another
+ matcher, for example:
+
+ ```cpp
+ MATCHER_P(NestedPropertyMatches, matcher, "") {
+ return ExplainMatchResult(matcher, arg.nested().property(), result_listener);
+ }
+ ```

+# Mocking Reference
+
+This page lists the facilities provided by GoogleTest for creating and working
+with mock objects. To use them, include the header
+`gmock/gmock.h`.
+
+## Macros {#macros}
+
+GoogleTest defines the following macros for working with mocks.
+
+### MOCK_METHOD {#MOCK_METHOD}
+
+`MOCK_METHOD(`*`return_type`*`,`*`method_name`*`, (`*`args...`*`));` \
+`MOCK_METHOD(`*`return_type`*`,`*`method_name`*`, (`*`args...`*`),
+(`*`specs...`*`));`
+
+Defines a mock method *`method_name`* with arguments `(`*`args...`*`)` and
+return type *`return_type`* within a mock class.
+
+The parameters of `MOCK_METHOD` mirror the method declaration. The optional
+fourth parameter *`specs...`* is a comma-separated list of qualifiers. The
+following qualifiers are accepted:
+
+| Qualifier | Meaning |
+| -------------------------- | -------------------------------------------- |
+| `const` | Makes the mocked method a `const` method. Required if overriding a `const` method. |
+| `override` | Marks the method with `override`. Recommended if overriding a `virtual` method. |
+| `noexcept` | Marks the method with `noexcept`. Required if overriding a `noexcept` method. |
+| `Calltype(`*`calltype`*`)` | Sets the call type for the method, for example `Calltype(STDMETHODCALLTYPE)`. Useful on Windows. |
+| `ref(`*`qualifier`*`)` | Marks the method with the given reference qualifier, for example `ref(&)` or `ref(&&)`. Required if overriding a method that has a reference qualifier. |
+
+Note that commas in arguments prevent `MOCK_METHOD` from parsing the arguments
+correctly if they are not appropriately surrounded by parentheses. See the
+following example:
+
+```cpp
+class MyMock {
+ public:
+ // The following 2 lines will not compile due to commas in the arguments:
+ MOCK_METHOD(std::pair<bool, int>, GetPair, ()); // Error!
+ MOCK_METHOD(bool, CheckMap, (std::map<int, double>, bool)); // Error!
+
+ // One solution - wrap arguments that contain commas in parentheses:
+ MOCK_METHOD((std::pair<bool, int>), GetPair, ());
+ MOCK_METHOD(bool, CheckMap, ((std::map<int, double>), bool));
+
+ // Another solution - use type aliases:
+ using BoolAndInt = std::pair<bool, int>;
+ MOCK_METHOD(BoolAndInt, GetPair, ());
+ using MapIntDouble = std::map<int, double>;
+ MOCK_METHOD(bool, CheckMap, (MapIntDouble, bool));
+};
+```
+
+`MOCK_METHOD` must be used in the `public:` section of a mock class definition,
+regardless of whether the method being mocked is `public`, `protected`, or
+`private` in the base class.
+
+### EXPECT_CALL {#EXPECT_CALL}
+
+`EXPECT_CALL(`*`mock_object`*`,`*`method_name`*`(`*`matchers...`*`))`
+
+Creates an [expectation](../gmock_for_dummies.md#setting-expectations) that the
+method *`method_name`* of the object *`mock_object`* is called with arguments
+that match the given matchers *`matchers...`*. `EXPECT_CALL` must precede any
+code that exercises the mock object.
+
+The parameter *`matchers...`* is a comma-separated list of
+[matchers](../gmock_for_dummies.md#matchers-what-arguments-do-we-expect) that
+correspond to each argument of the method *`method_name`*. The expectation will
+apply only to calls of *`method_name`* whose arguments match all of the
+matchers. If `(`*`matchers...`*`)` is omitted, the expectation behaves as if
+each argument's matcher were a [wildcard matcher (`_`)](matchers.md#wildcard).
+See the [Matchers Reference](matchers.md) for a list of all built-in matchers.
+
+The following chainable clauses can be used to modify the expectation, and they
+must be used in the following order:
+
+```cpp
+EXPECT_CALL(mock_object, method_name(matchers...))
+ .With(multi_argument_matcher) // Can be used at most once
+ .Times(cardinality) // Can be used at most once
+ .InSequence(sequences...) // Can be used any number of times
+ .After(expectations...) // Can be used any number of times
+ .WillOnce(action) // Can be used any number of times
+ .WillRepeatedly(action) // Can be used at most once
+ .RetiresOnSaturation(); // Can be used at most once
+```
+
+See details for each modifier clause below.
+
+#### With {#EXPECT_CALL.With}
+
+`.With(`*`multi_argument_matcher`*`)`
+
+Restricts the expectation to apply only to mock function calls whose arguments
+as a whole match the multi-argument matcher *`multi_argument_matcher`*.
+
+GoogleTest passes all of the arguments as one tuple into the matcher. The
+parameter *`multi_argument_matcher`* must thus be a matcher of type
+`Matcher<std::tuple<A1, ..., An>>`, where `A1, ..., An` are the types of the
+function arguments.
+
+For example, the following code sets the expectation that
+`my_mock.SetPosition()` is called with any two arguments, the first argument
+being less than the second:
+
+```cpp
+using ::testing::_;
+using ::testing::Lt;
+...
+EXPECT_CALL(my_mock, SetPosition(_, _))
+ .With(Lt());
+```
+
+GoogleTest provides some built-in matchers for 2-tuples, including the `Lt()`
+matcher above. See [Multi-argument Matchers](matchers.md#MultiArgMatchers).
+
+The `With` clause can be used at most once on an expectation and must be the
+first clause.
+
+#### Times {#EXPECT_CALL.Times}
+
+`.Times(`*`cardinality`*`)`
+
+Specifies how many times the mock function call is expected.
+
+The parameter *`cardinality`* represents the number of expected calls and can be
+one of the following, all defined in the `::testing` namespace:
+
+| Cardinality | Meaning |
+| ------------------- | --------------------------------------------------- |
+| `AnyNumber()` | The function can be called any number of times. |
+| `AtLeast(n)` | The function call is expected at least *n* times. |
+| `AtMost(n)` | The function call is expected at most *n* times. |
+| `Between(m, n)` | The function call is expected between *m* and *n* times, inclusive. |
+| `Exactly(n)` or `n` | The function call is expected exactly *n* times. If *n* is 0, the call should never happen. |
+
+If the `Times` clause is omitted, GoogleTest infers the cardinality as follows:
+
+* If neither [`WillOnce`](#EXPECT_CALL.WillOnce) nor
+ [`WillRepeatedly`](#EXPECT_CALL.WillRepeatedly) are specified, the inferred
+ cardinality is `Times(1)`.
+* If there are *n* `WillOnce` clauses and no `WillRepeatedly` clause, where
+ *n* >= 1, the inferred cardinality is `Times(n)`.
+* If there are *n* `WillOnce` clauses and one `WillRepeatedly` clause, where
+ *n* >= 0, the inferred cardinality is `Times(AtLeast(n))`.
+
+The `Times` clause can be used at most once on an expectation.
+
+#### InSequence {#EXPECT_CALL.InSequence}
+
+`.InSequence(`*`sequences...`*`)`
+
+Specifies that the mock function call is expected in a certain sequence.
+
+The parameter *`sequences...`* is any number of [`Sequence`](#Sequence) objects.
+Expected calls assigned to the same sequence are expected to occur in the order
+the expectations are declared.
+
+For example, the following code sets the expectation that the `Reset()` method
+of `my_mock` is called before both `GetSize()` and `Describe()`, and `GetSize()`
+and `Describe()` can occur in any order relative to each other:
+
+```cpp
+using ::testing::Sequence;
+Sequence s1, s2;
+...
+EXPECT_CALL(my_mock, Reset())
+ .InSequence(s1, s2);
+EXPECT_CALL(my_mock, GetSize())
+ .InSequence(s1);
+EXPECT_CALL(my_mock, Describe())
+ .InSequence(s2);
+```
+
+The `InSequence` clause can be used any number of times on an expectation.
+
+See also the [`InSequence` class](#InSequence).
+
+#### After {#EXPECT_CALL.After}
+
+`.After(`*`expectations...`*`)`
+
+Specifies that the mock function call is expected to occur after one or more
+other calls.
+
+The parameter *`expectations...`* can be up to five
+[`Expectation`](#Expectation) or [`ExpectationSet`](#ExpectationSet) objects.
+The mock function call is expected to occur after all of the given expectations.
+
+For example, the following code sets the expectation that the `Describe()`
+method of `my_mock` is called only after both `InitX()` and `InitY()` have been
+called.
+
+```cpp
+using ::testing::Expectation;
+...
+Expectation init_x = EXPECT_CALL(my_mock, InitX());
+Expectation init_y = EXPECT_CALL(my_mock, InitY());
+EXPECT_CALL(my_mock, Describe())
+ .After(init_x, init_y);
+```
+
+The `ExpectationSet` object is helpful when the number of prerequisites for an
+expectation is large or variable, for example:
+
+```cpp
+using ::testing::ExpectationSet;
+...
+ExpectationSet all_inits;
+// Collect all expectations of InitElement() calls
+for (int i = 0; i < element_count; i++) {
+ all_inits += EXPECT_CALL(my_mock, InitElement(i));
+}
+EXPECT_CALL(my_mock, Describe())
+ .After(all_inits); // Expect Describe() call after all InitElement() calls
+```
+
+The `After` clause can be used any number of times on an expectation.
+
+#### WillOnce {#EXPECT_CALL.WillOnce}
+
+`.WillOnce(`*`action`*`)`
+
+Specifies the mock function's actual behavior when invoked, for a single
+matching function call.
+
+The parameter *`action`* represents the
+[action](../gmock_for_dummies.md#actions-what-should-it-do) that the function
+call will perform. See the [Actions Reference](actions.md) for a list of
+built-in actions.
+
+The use of `WillOnce` implicitly sets a cardinality on the expectation when
+`Times` is not specified. See [`Times`](#EXPECT_CALL.Times).
+
+Each matching function call will perform the next action in the order declared.
+For example, the following code specifies that `my_mock.GetNumber()` is expected
+to be called exactly 3 times and will return `1`, `2`, and `3` respectively on
+the first, second, and third calls:
+
+```cpp
+using ::testing::Return;
+...
+EXPECT_CALL(my_mock, GetNumber())
+ .WillOnce(Return(1))
+ .WillOnce(Return(2))
+ .WillOnce(Return(3));
+```
+
+The `WillOnce` clause can be used any number of times on an expectation.
+
+#### WillRepeatedly {#EXPECT_CALL.WillRepeatedly}
+
+`.WillRepeatedly(`*`action`*`)`
+
+Specifies the mock function's actual behavior when invoked, for all subsequent
+matching function calls. Takes effect after the actions specified in the
+[`WillOnce`](#EXPECT_CALL.WillOnce) clauses, if any, have been performed.
+
+The parameter *`action`* represents the
+[action](../gmock_for_dummies.md#actions-what-should-it-do) that the function
+call will perform. See the [Actions Reference](actions.md) for a list of
+built-in actions.
+
+The use of `WillRepeatedly` implicitly sets a cardinality on the expectation
+when `Times` is not specified. See [`Times`](#EXPECT_CALL.Times).
+
+If any `WillOnce` clauses have been specified, matching function calls will
+perform those actions before the action specified by `WillRepeatedly`. See the
+following example:
+
+```cpp
+using ::testing::Return;
+...
+EXPECT_CALL(my_mock, GetName())
+ .WillRepeatedly(Return("John Doe")); // Return "John Doe" on all calls
+
+EXPECT_CALL(my_mock, GetNumber())
+ .WillOnce(Return(42)) // Return 42 on the first call
+ .WillRepeatedly(Return(7)); // Return 7 on all subsequent calls
+```
+
+The `WillRepeatedly` clause can be used at most once on an expectation.
+
+#### RetiresOnSaturation {#EXPECT_CALL.RetiresOnSaturation}
+
+`.RetiresOnSaturation()`
+
+Indicates that the expectation will no longer be active after the expected
+number of matching function calls has been reached.
+
+The `RetiresOnSaturation` clause is only meaningful for expectations with an
+upper-bounded cardinality. The expectation will *retire* (no longer match any
+function calls) after it has been *saturated* (the upper bound has been
+reached). See the following example:
+
+```cpp
+using ::testing::_;
+using ::testing::AnyNumber;
+...
+EXPECT_CALL(my_mock, SetNumber(_)) // Expectation 1
+ .Times(AnyNumber());
+EXPECT_CALL(my_mock, SetNumber(7)) // Expectation 2
+ .Times(2)
+ .RetiresOnSaturation();
+```
+
+In the above example, the first two calls to `my_mock.SetNumber(7)` match
+expectation 2, which then becomes inactive and no longer matches any calls. A
+third call to `my_mock.SetNumber(7)` would then match expectation 1. Without
+`RetiresOnSaturation()` on expectation 2, a third call to `my_mock.SetNumber(7)`
+would match expectation 2 again, producing a failure since the limit of 2 calls
+was exceeded.
+
+The `RetiresOnSaturation` clause can be used at most once on an expectation and
+must be the last clause.
+
+### ON_CALL {#ON_CALL}
+
+`ON_CALL(`*`mock_object`*`,`*`method_name`*`(`*`matchers...`*`))`
+
+Defines what happens when the method *`method_name`* of the object
+*`mock_object`* is called with arguments that match the given matchers
+*`matchers...`*. Requires a modifier clause to specify the method's behavior.
+*Does not* set any expectations that the method will be called.
+
+The parameter *`matchers...`* is a comma-separated list of
+[matchers](../gmock_for_dummies.md#matchers-what-arguments-do-we-expect) that
+correspond to each argument of the method *`method_name`*. The `ON_CALL`
+specification will apply only to calls of *`method_name`* whose arguments match
+all of the matchers. If `(`*`matchers...`*`)` is omitted, the behavior is as if
+each argument's matcher were a [wildcard matcher (`_`)](matchers.md#wildcard).
+See the [Matchers Reference](matchers.md) for a list of all built-in matchers.
+
+The following chainable clauses can be used to set the method's behavior, and
+they must be used in the following order:
+
+```cpp
+ON_CALL(mock_object, method_name(matchers...))
+ .With(multi_argument_matcher) // Can be used at most once
+ .WillByDefault(action); // Required
+```
+
+See details for each modifier clause below.
+
+#### With {#ON_CALL.With}
+
+`.With(`*`multi_argument_matcher`*`)`
+
+Restricts the specification to only mock function calls whose arguments as a
+whole match the multi-argument matcher *`multi_argument_matcher`*.
+
+GoogleTest passes all of the arguments as one tuple into the matcher. The
+parameter *`multi_argument_matcher`* must thus be a matcher of type
+`Matcher<std::tuple<A1, ..., An>>`, where `A1, ..., An` are the types of the
+function arguments.
+
+For example, the following code sets the default behavior when
+`my_mock.SetPosition()` is called with any two arguments, the first argument
+being less than the second:
+
+```cpp
+using ::testing::_;
+using ::testing::Lt;
+using ::testing::Return;
+...
+ON_CALL(my_mock, SetPosition(_, _))
+ .With(Lt())
+ .WillByDefault(Return(true));
+```
+
+GoogleTest provides some built-in matchers for 2-tuples, including the `Lt()`
+matcher above. See [Multi-argument Matchers](matchers.md#MultiArgMatchers).
+
+The `With` clause can be used at most once with each `ON_CALL` statement.
+
+#### WillByDefault {#ON_CALL.WillByDefault}
+
+`.WillByDefault(`*`action`*`)`
+
+Specifies the default behavior of a matching mock function call.
+
+The parameter *`action`* represents the
+[action](../gmock_for_dummies.md#actions-what-should-it-do) that the function
+call will perform. See the [Actions Reference](actions.md) for a list of
+built-in actions.
+
+For example, the following code specifies that by default, a call to
+`my_mock.Greet()` will return `"hello"`:
+
+```cpp
+using ::testing::Return;
+...
+ON_CALL(my_mock, Greet())
+ .WillByDefault(Return("hello"));
+```
+
+The action specified by `WillByDefault` is superseded by the actions specified
+on a matching `EXPECT_CALL` statement, if any. See the
+[`WillOnce`](#EXPECT_CALL.WillOnce) and
+[`WillRepeatedly`](#EXPECT_CALL.WillRepeatedly) clauses of `EXPECT_CALL`.
+
+The `WillByDefault` clause must be used exactly once with each `ON_CALL`
+statement.
+
+## Classes {#classes}
+
+GoogleTest defines the following classes for working with mocks.
+
+### DefaultValue {#DefaultValue}
+
+`::testing::DefaultValue<T>`
+
+Allows a user to specify the default value for a type `T` that is both copyable
+and publicly destructible (i.e. anything that can be used as a function return
+type). For mock functions with a return type of `T`, this default value is
+returned from function calls that do not specify an action.
+
+Provides the static methods `Set()`, `SetFactory()`, and `Clear()` to manage the
+default value:
+
+```cpp
+// Sets the default value to be returned. T must be copy constructible.
+DefaultValue<T>::Set(value);
+
+// Sets a factory. Will be invoked on demand. T must be move constructible.
+T MakeT();
+DefaultValue<T>::SetFactory(&MakeT);
+
+// Unsets the default value.
+DefaultValue<T>::Clear();
+```
+
+### NiceMock {#NiceMock}
+
+`::testing::NiceMock<T>`
+
+Represents a mock object that suppresses warnings on
+[uninteresting calls](../gmock_cook_book.md#uninteresting-vs-unexpected). The
+template parameter `T` is any mock class, except for another `NiceMock`,
+`NaggyMock`, or `StrictMock`.
+
+Usage of `NiceMock<T>` is analogous to usage of `T`. `NiceMock<T>` is a subclass
+of `T`, so it can be used wherever an object of type `T` is accepted. In
+addition, `NiceMock<T>` can be constructed with any arguments that a constructor
+of `T` accepts.
+
+For example, the following code suppresses warnings on the mock `my_mock` of
+type `MockClass` if a method other than `DoSomething()` is called:
+
+```cpp
+using ::testing::NiceMock;
+...
+NiceMock<MockClass> my_mock("some", "args");
+EXPECT_CALL(my_mock, DoSomething());
+... code that uses my_mock ...
+```
+
+`NiceMock<T>` only works for mock methods defined using the `MOCK_METHOD` macro
+directly in the definition of class `T`. If a mock method is defined in a base
+class of `T`, a warning might still be generated.
+
+`NiceMock<T>` might not work correctly if the destructor of `T` is not virtual.
+
+### NaggyMock {#NaggyMock}
+
+`::testing::NaggyMock<T>`
+
+Represents a mock object that generates warnings on
+[uninteresting calls](../gmock_cook_book.md#uninteresting-vs-unexpected). The
+template parameter `T` is any mock class, except for another `NiceMock`,
+`NaggyMock`, or `StrictMock`.
+
+Usage of `NaggyMock<T>` is analogous to usage of `T`. `NaggyMock<T>` is a
+subclass of `T`, so it can be used wherever an object of type `T` is accepted.
+In addition, `NaggyMock<T>` can be constructed with any arguments that a
+constructor of `T` accepts.
+
+For example, the following code generates warnings on the mock `my_mock` of type
+`MockClass` if a method other than `DoSomething()` is called:
+
+```cpp
+using ::testing::NaggyMock;
+...
+NaggyMock<MockClass> my_mock("some", "args");
+EXPECT_CALL(my_mock, DoSomething());
+... code that uses my_mock ...
+```
+
+Mock objects of type `T` by default behave the same way as `NaggyMock<T>`.
+
+### StrictMock {#StrictMock}
+
+`::testing::StrictMock<T>`
+
+Represents a mock object that generates test failures on
+[uninteresting calls](../gmock_cook_book.md#uninteresting-vs-unexpected). The
+template parameter `T` is any mock class, except for another `NiceMock`,
+`NaggyMock`, or `StrictMock`.
+
+Usage of `StrictMock<T>` is analogous to usage of `T`. `StrictMock<T>` is a
+subclass of `T`, so it can be used wherever an object of type `T` is accepted.
+In addition, `StrictMock<T>` can be constructed with any arguments that a
+constructor of `T` accepts.
+
+For example, the following code generates a test failure on the mock `my_mock`
+of type `MockClass` if a method other than `DoSomething()` is called:
+
+```cpp
+using ::testing::StrictMock;
+...
+StrictMock<MockClass> my_mock("some", "args");
+EXPECT_CALL(my_mock, DoSomething());
+... code that uses my_mock ...
+```
+
+`StrictMock<T>` only works for mock methods defined using the `MOCK_METHOD`
+macro directly in the definition of class `T`. If a mock method is defined in a
+base class of `T`, a failure might not be generated.
+
+`StrictMock<T>` might not work correctly if the destructor of `T` is not
+virtual.
+
+### Sequence {#Sequence}
+
+`::testing::Sequence`
+
+Represents a chronological sequence of expectations. See the
+[`InSequence`](#EXPECT_CALL.InSequence) clause of `EXPECT_CALL` for usage.
+
+### InSequence {#InSequence}
+
+`::testing::InSequence`
+
+An object of this type causes all expectations encountered in its scope to be
+put in an anonymous sequence.
+
+This allows more convenient expression of multiple expectations in a single
+sequence:
+
+```cpp
+using ::testing::InSequence;
+{
+ InSequence seq;
+
+ // The following are expected to occur in the order declared.
+ EXPECT_CALL(...);
+ EXPECT_CALL(...);
+ ...
+ EXPECT_CALL(...);
+}
+```
+
+The name of the `InSequence` object does not matter.
+
+### Expectation {#Expectation}
+
+`::testing::Expectation`
+
+Represents a mock function call expectation as created by
+[`EXPECT_CALL`](#EXPECT_CALL):
+
+```cpp
+using ::testing::Expectation;
+Expectation my_expectation = EXPECT_CALL(...);
+```
+
+Useful for specifying sequences of expectations; see the
+[`After`](#EXPECT_CALL.After) clause of `EXPECT_CALL`.
+
+### ExpectationSet {#ExpectationSet}
+
+`::testing::ExpectationSet`
+
+Represents a set of mock function call expectations.
+
+Use the `+=` operator to add [`Expectation`](#Expectation) objects to the set:
+
+```cpp
+using ::testing::ExpectationSet;
+ExpectationSet my_expectations;
+my_expectations += EXPECT_CALL(...);
+```
+
+Useful for specifying sequences of expectations; see the
+[`After`](#EXPECT_CALL.After) clause of `EXPECT_CALL`.

+# Testing Reference
+
+<!--* toc_depth: 3 *-->
+
+This page lists the facilities provided by GoogleTest for writing test programs.
+To use them, include the header `gtest/gtest.h`.
+
+## Macros
+
+GoogleTest defines the following macros for writing tests.
+
+### TEST {#TEST}
+
+<pre>
+TEST(<em>TestSuiteName</em>, <em>TestName</em>) {
+ ... <em>statements</em> ...
+}
+</pre>
+
+Defines an individual test named *`TestName`* in the test suite
+*`TestSuiteName`*, consisting of the given statements.
+
+Both arguments *`TestSuiteName`* and *`TestName`* must be valid C++ identifiers
+and must not contain underscores (`_`). Tests in different test suites can have
+the same individual name.
+
+The statements within the test body can be any code under test.
+[Assertions](assertions.md) used within the test body determine the outcome of
+the test.
+
+### TEST_F {#TEST_F}
+
+<pre>
+TEST_F(<em>TestFixtureName</em>, <em>TestName</em>) {
+ ... <em>statements</em> ...
+}
+</pre>
+
+Defines an individual test named *`TestName`* that uses the test fixture class
+*`TestFixtureName`*. The test suite name is *`TestFixtureName`*.
+
+Both arguments *`TestFixtureName`* and *`TestName`* must be valid C++
+identifiers and must not contain underscores (`_`). *`TestFixtureName`* must be
+the name of a test fixture class—see
+[Test Fixtures](../primer.md#same-data-multiple-tests).
+
+The statements within the test body can be any code under test.
+[Assertions](assertions.md) used within the test body determine the outcome of
+the test.
+
+### TEST_P {#TEST_P}
+
+<pre>
+TEST_P(<em>TestFixtureName</em>, <em>TestName</em>) {
+ ... <em>statements</em> ...
+}
+</pre>
+
+Defines an individual value-parameterized test named *`TestName`* that uses the
+test fixture class *`TestFixtureName`*. The test suite name is
+*`TestFixtureName`*.
+
+Both arguments *`TestFixtureName`* and *`TestName`* must be valid C++
+identifiers and must not contain underscores (`_`). *`TestFixtureName`* must be
+the name of a value-parameterized test fixture class—see
+[Value-Parameterized Tests](../advanced.md#value-parameterized-tests).
+
+The statements within the test body can be any code under test. Within the test
+body, the test parameter can be accessed with the `GetParam()` function (see
+[`WithParamInterface`](#WithParamInterface)). For example:
+
+```cpp
+TEST_P(MyTestSuite, DoesSomething) {
+ ...
+ EXPECT_TRUE(DoSomething(GetParam()));
+ ...
+}
+```
+
+[Assertions](assertions.md) used within the test body determine the outcome of
+the test.
+
+See also [`INSTANTIATE_TEST_SUITE_P`](#INSTANTIATE_TEST_SUITE_P).
+
+### INSTANTIATE_TEST_SUITE_P {#INSTANTIATE_TEST_SUITE_P}
+
+`INSTANTIATE_TEST_SUITE_P(`*`InstantiationName`*`,`*`TestSuiteName`*`,`*`param_generator`*`)`
+\
+`INSTANTIATE_TEST_SUITE_P(`*`InstantiationName`*`,`*`TestSuiteName`*`,`*`param_generator`*`,`*`name_generator`*`)`
+
+Instantiates the value-parameterized test suite *`TestSuiteName`* (defined with
+[`TEST_P`](#TEST_P)).
+
+The argument *`InstantiationName`* is a unique name for the instantiation of the
+test suite, to distinguish between multiple instantiations. In test output, the
+instantiation name is added as a prefix to the test suite name
+*`TestSuiteName`*.
+
+The argument *`param_generator`* is one of the following GoogleTest-provided
+functions that generate the test parameters, all defined in the `::testing`
+namespace:
+
+<span id="param-generators"></span>
+
+| Parameter Generator | Behavior |
+| ------------------- | ---------------------------------------------------- |
+| `Range(begin, end [, step])` | Yields values `{begin, begin+step, begin+step+step, ...}`. The values do not include `end`. `step` defaults to 1. |
+| `Values(v1, v2, ..., vN)` | Yields values `{v1, v2, ..., vN}`. |
+| `ValuesIn(container)` or `ValuesIn(begin,end)` | Yields values from a C-style array, an STL-style container, or an iterator range `[begin, end)`. |
+| `Bool()` | Yields sequence `{false, true}`. |
+| `Combine(g1, g2, ..., gN)` | Yields as `std::tuple` *n*-tuples all combinations (Cartesian product) of the values generated by the given *n* generators `g1`, `g2`, ..., `gN`. |
+
+The optional last argument *`name_generator`* is a function or functor that
+generates custom test name suffixes based on the test parameters. The function
+must accept an argument of type
+[`TestParamInfo<class ParamType>`](#TestParamInfo) and return a `std::string`.
+The test name suffix can only contain alphanumeric characters and underscores.
+GoogleTest provides [`PrintToStringParamName`](#PrintToStringParamName), or a
+custom function can be used for more control:
+
+```cpp
+INSTANTIATE_TEST_SUITE_P(
+ MyInstantiation, MyTestSuite,
+ ::testing::Values(...),
+ [](const ::testing::TestParamInfo<MyTestSuite::ParamType>& info) {
+ // Can use info.param here to generate the test suffix
+ std::string name = ...
+ return name;
+ });
+```
+
+For more information, see
+[Value-Parameterized Tests](../advanced.md#value-parameterized-tests).
+
+See also
+[`GTEST_ALLOW_UNINSTANTIATED_PARAMETERIZED_TEST`](#GTEST_ALLOW_UNINSTANTIATED_PARAMETERIZED_TEST).
+
+### TYPED_TEST_SUITE {#TYPED_TEST_SUITE}
+
+`TYPED_TEST_SUITE(`*`TestFixtureName`*`,`*`Types`*`)`
+
+Defines a typed test suite based on the test fixture *`TestFixtureName`*. The
+test suite name is *`TestFixtureName`*.
+
+The argument *`TestFixtureName`* is a fixture class template, parameterized by a
+type, for example:
+
+```cpp
+template <typename T>
+class MyFixture : public ::testing::Test {
+ public:
+ ...
+ using List = std::list<T>;
+ static T shared_;
+ T value_;
+};
+```
+
+The argument *`Types`* is a [`Types`](#Types) object representing the list of
+types to run the tests on, for example:
+
+```cpp
+using MyTypes = ::testing::Types<char, int, unsigned int>;
+TYPED_TEST_SUITE(MyFixture, MyTypes);
+```
+
+The type alias (`using` or `typedef`) is necessary for the `TYPED_TEST_SUITE`
+macro to parse correctly.
+
+See also [`TYPED_TEST`](#TYPED_TEST) and
+[Typed Tests](../advanced.md#typed-tests) for more information.
+
+### TYPED_TEST {#TYPED_TEST}
+
+<pre>
+TYPED_TEST(<em>TestSuiteName</em>, <em>TestName</em>) {
+ ... <em>statements</em> ...
+}
+</pre>
+
+Defines an individual typed test named *`TestName`* in the typed test suite
+*`TestSuiteName`*. The test suite must be defined with
+[`TYPED_TEST_SUITE`](#TYPED_TEST_SUITE).
+
+Within the test body, the special name `TypeParam` refers to the type parameter,
+and `TestFixture` refers to the fixture class. See the following example:
+
+```cpp
+TYPED_TEST(MyFixture, Example) {
+ // Inside a test, refer to the special name TypeParam to get the type
+ // parameter. Since we are inside a derived class template, C++ requires
+ // us to visit the members of MyFixture via 'this'.
+ TypeParam n = this->value_;
+
+ // To visit static members of the fixture, add the 'TestFixture::'
+ // prefix.
+ n += TestFixture::shared_;
+
+ // To refer to typedefs in the fixture, add the 'typename TestFixture::'
+ // prefix. The 'typename' is required to satisfy the compiler.
+ typename TestFixture::List values;
+
+ values.push_back(n);
+ ...
+}
+```
+
+For more information, see [Typed Tests](../advanced.md#typed-tests).
+
+### TYPED_TEST_SUITE_P {#TYPED_TEST_SUITE_P}
+
+`TYPED_TEST_SUITE_P(`*`TestFixtureName`*`)`
+
+Defines a type-parameterized test suite based on the test fixture
+*`TestFixtureName`*. The test suite name is *`TestFixtureName`*.
+
+The argument *`TestFixtureName`* is a fixture class template, parameterized by a
+type. See [`TYPED_TEST_SUITE`](#TYPED_TEST_SUITE) for an example.
+
+See also [`TYPED_TEST_P`](#TYPED_TEST_P) and
+[Type-Parameterized Tests](../advanced.md#type-parameterized-tests) for more
+information.
+
+### TYPED_TEST_P {#TYPED_TEST_P}
+
+<pre>
+TYPED_TEST_P(<em>TestSuiteName</em>, <em>TestName</em>) {
+ ... <em>statements</em> ...
+}
+</pre>
+
+Defines an individual type-parameterized test named *`TestName`* in the
+type-parameterized test suite *`TestSuiteName`*. The test suite must be defined
+with [`TYPED_TEST_SUITE_P`](#TYPED_TEST_SUITE_P).
+
+Within the test body, the special name `TypeParam` refers to the type parameter,
+and `TestFixture` refers to the fixture class. See [`TYPED_TEST`](#TYPED_TEST)
+for an example.
+
+See also [`REGISTER_TYPED_TEST_SUITE_P`](#REGISTER_TYPED_TEST_SUITE_P) and
+[Type-Parameterized Tests](../advanced.md#type-parameterized-tests) for more
+information.
+
+### REGISTER_TYPED_TEST_SUITE_P {#REGISTER_TYPED_TEST_SUITE_P}
+
+`REGISTER_TYPED_TEST_SUITE_P(`*`TestSuiteName`*`,`*`TestNames...`*`)`
+
+Registers the type-parameterized tests *`TestNames...`* of the test suite
+*`TestSuiteName`*. The test suite and tests must be defined with
+[`TYPED_TEST_SUITE_P`](#TYPED_TEST_SUITE_P) and [`TYPED_TEST_P`](#TYPED_TEST_P).
+
+For example:
+
+```cpp
+// Define the test suite and tests.
+TYPED_TEST_SUITE_P(MyFixture);
+TYPED_TEST_P(MyFixture, HasPropertyA) { ... }
+TYPED_TEST_P(MyFixture, HasPropertyB) { ... }
+
+// Register the tests in the test suite.
+REGISTER_TYPED_TEST_SUITE_P(MyFixture, HasPropertyA, HasPropertyB);
+```
+
+See also [`INSTANTIATE_TYPED_TEST_SUITE_P`](#INSTANTIATE_TYPED_TEST_SUITE_P) and
+[Type-Parameterized Tests](../advanced.md#type-parameterized-tests) for more
+information.
+
+### INSTANTIATE_TYPED_TEST_SUITE_P {#INSTANTIATE_TYPED_TEST_SUITE_P}
+
+`INSTANTIATE_TYPED_TEST_SUITE_P(`*`InstantiationName`*`,`*`TestSuiteName`*`,`*`Types`*`)`
+
+Instantiates the type-parameterized test suite *`TestSuiteName`*. The test suite
+must be registered with
+[`REGISTER_TYPED_TEST_SUITE_P`](#REGISTER_TYPED_TEST_SUITE_P).
+
+The argument *`InstantiationName`* is a unique name for the instantiation of the
+test suite, to distinguish between multiple instantiations. In test output, the
+instantiation name is added as a prefix to the test suite name
+*`TestSuiteName`*.
+
+The argument *`Types`* is a [`Types`](#Types) object representing the list of
+types to run the tests on, for example:
+
+```cpp
+using MyTypes = ::testing::Types<char, int, unsigned int>;
+INSTANTIATE_TYPED_TEST_SUITE_P(MyInstantiation, MyFixture, MyTypes);
+```
+
+The type alias (`using` or `typedef`) is necessary for the
+`INSTANTIATE_TYPED_TEST_SUITE_P` macro to parse correctly.
+
+For more information, see
+[Type-Parameterized Tests](../advanced.md#type-parameterized-tests).
+
+### FRIEND_TEST {#FRIEND_TEST}
+
+`FRIEND_TEST(`*`TestSuiteName`*`,`*`TestName`*`)`
+
+Within a class body, declares an individual test as a friend of the class,
+enabling the test to access private class members.
+
+If the class is defined in a namespace, then in order to be friends of the
+class, test fixtures and tests must be defined in the exact same namespace,
+without inline or anonymous namespaces.
+
+For example, if the class definition looks like the following:
+
+```cpp
+namespace my_namespace {
+
+class MyClass {
+ friend class MyClassTest;
+ FRIEND_TEST(MyClassTest, HasPropertyA);
+ FRIEND_TEST(MyClassTest, HasPropertyB);
+ ... definition of class MyClass ...
+};
+
+} // namespace my_namespace
+```
+
+Then the test code should look like:
+
+```cpp
+namespace my_namespace {
+
+class MyClassTest : public ::testing::Test {
+ ...
+};
+
+TEST_F(MyClassTest, HasPropertyA) { ... }
+TEST_F(MyClassTest, HasPropertyB) { ... }
+
+} // namespace my_namespace
+```
+
+See [Testing Private Code](../advanced.md#testing-private-code) for more
+information.
+
+### SCOPED_TRACE {#SCOPED_TRACE}
+
+`SCOPED_TRACE(`*`message`*`)`
+
+Causes the current file name, line number, and the given message *`message`* to
+be added to the failure message for each assertion failure that occurs in the
+scope.
+
+For more information, see
+[Adding Traces to Assertions](../advanced.md#adding-traces-to-assertions).
+
+See also the [`ScopedTrace` class](#ScopedTrace).
+
+### GTEST_SKIP {#GTEST_SKIP}
+
+`GTEST_SKIP()`
+
+Prevents further test execution at runtime.
+
+Can be used in individual test cases or in the `SetUp()` methods of test
+environments or test fixtures (classes derived from the
+[`Environment`](#Environment) or [`Test`](#Test) classes). If used in a global
+test environment `SetUp()` method, it skips all tests in the test program. If
+used in a test fixture `SetUp()` method, it skips all tests in the corresponding
+test suite.
+
+Similar to assertions, `GTEST_SKIP` allows streaming a custom message into it.
+
+See [Skipping Test Execution](../advanced.md#skipping-test-execution) for more
+information.
+
+### GTEST_ALLOW_UNINSTANTIATED_PARAMETERIZED_TEST {#GTEST_ALLOW_UNINSTANTIATED_PARAMETERIZED_TEST}
+
+`GTEST_ALLOW_UNINSTANTIATED_PARAMETERIZED_TEST(`*`TestSuiteName`*`)`
+
+Allows the value-parameterized test suite *`TestSuiteName`* to be
+uninstantiated.
+
+By default, every [`TEST_P`](#TEST_P) call without a corresponding
+[`INSTANTIATE_TEST_SUITE_P`](#INSTANTIATE_TEST_SUITE_P) call causes a failing
+test in the test suite `GoogleTestVerification`.
+`GTEST_ALLOW_UNINSTANTIATED_PARAMETERIZED_TEST` suppresses this failure for the
+given test suite.
+
+## Classes and types
+
+GoogleTest defines the following classes and types to help with writing tests.
+
+### AssertionResult {#AssertionResult}
+
+`::testing::AssertionResult`
+
+A class for indicating whether an assertion was successful.
+
+When the assertion wasn't successful, the `AssertionResult` object stores a
+non-empty failure message that can be retrieved with the object's `message()`
+method.
+
+To create an instance of this class, use one of the factory functions
+[`AssertionSuccess()`](#AssertionSuccess) or
+[`AssertionFailure()`](#AssertionFailure).
+
+### AssertionException {#AssertionException}
+
+`::testing::AssertionException`
+
+Exception which can be thrown from
+[`TestEventListener::OnTestPartResult`](#TestEventListener::OnTestPartResult).
+
+### EmptyTestEventListener {#EmptyTestEventListener}
+
+`::testing::EmptyTestEventListener`
+
+Provides an empty implementation of all methods in the
+[`TestEventListener`](#TestEventListener) interface, such that a subclass only
+needs to override the methods it cares about.
+
+### Environment {#Environment}
+
+`::testing::Environment`
+
+Represents a global test environment. See
+[Global Set-Up and Tear-Down](../advanced.md#global-set-up-and-tear-down).
+
+#### Protected Methods {#Environment-protected}
+
+##### SetUp {#Environment::SetUp}
+
+`virtual void Environment::SetUp()`
+
+Override this to define how to set up the environment.
+
+##### TearDown {#Environment::TearDown}
+
+`virtual void Environment::TearDown()`
+
+Override this to define how to tear down the environment.
+
+### ScopedTrace {#ScopedTrace}
+
+`::testing::ScopedTrace`
+
+An instance of this class causes a trace to be included in every test failure
+message generated by code in the scope of the lifetime of the `ScopedTrace`
+instance. The effect is undone with the destruction of the instance.
+
+The `ScopedTrace` constructor has the following form:
+
+```cpp
+template <typename T>
+ScopedTrace(const char* file, int line, const T& message)
+```
+
+Example usage:
+
+```cpp
+::testing::ScopedTrace trace("file.cc", 123, "message");
+```
+
+The resulting trace includes the given source file path and line number, and the
+given message. The `message` argument can be anything streamable to
+`std::ostream`.
+
+See also [`SCOPED_TRACE`](#SCOPED_TRACE).
+
+### Test {#Test}
+
+`::testing::Test`
+
+The abstract class that all tests inherit from. `Test` is not copyable.
+
+#### Public Methods {#Test-public}
+
+##### SetUpTestSuite {#Test::SetUpTestSuite}
+
+`static void Test::SetUpTestSuite()`
+
+Performs shared setup for all tests in the test suite. GoogleTest calls
+`SetUpTestSuite()` before running the first test in the test suite.
+
+##### TearDownTestSuite {#Test::TearDownTestSuite}
+
+`static void Test::TearDownTestSuite()`
+
+Performs shared teardown for all tests in the test suite. GoogleTest calls
+`TearDownTestSuite()` after running the last test in the test suite.
+
+##### HasFatalFailure {#Test::HasFatalFailure}
+
+`static bool Test::HasFatalFailure()`
+
+Returns true if and only if the current test has a fatal failure.
+
+##### HasNonfatalFailure {#Test::HasNonfatalFailure}
+
+`static bool Test::HasNonfatalFailure()`
+
+Returns true if and only if the current test has a nonfatal failure.
+
+##### HasFailure {#Test::HasFailure}
+
+`static bool Test::HasFailure()`
+
+Returns true if and only if the current test has any failure, either fatal or
+nonfatal.
+
+##### IsSkipped {#Test::IsSkipped}
+
+`static bool Test::IsSkipped()`
+
+Returns true if and only if the current test was skipped.
+
+##### RecordProperty {#Test::RecordProperty}
+
+`static void Test::RecordProperty(const std::string& key, const std::string&
+value)` \
+`static void Test::RecordProperty(const std::string& key, int value)`
+
+Logs a property for the current test, test suite, or entire invocation of the
+test program. Only the last value for a given key is logged.
+
+The key must be a valid XML attribute name, and cannot conflict with the ones
+already used by GoogleTest (`name`, `status`, `time`, `classname`, `type_param`,
+and `value_param`).
+
+`RecordProperty` is `public static` so it can be called from utility functions
+that are not members of the test fixture.
+
+Calls to `RecordProperty` made during the lifespan of the test (from the moment
+its constructor starts to the moment its destructor finishes) are output in XML
+as attributes of the `<testcase>` element. Properties recorded from a fixture's
+`SetUpTestSuite` or `TearDownTestSuite` methods are logged as attributes of the
+corresponding `<testsuite>` element. Calls to `RecordProperty` made in the
+global context (before or after invocation of `RUN_ALL_TESTS` or from the
+`SetUp`/`TearDown` methods of registered `Environment` objects) are output as
+attributes of the `<testsuites>` element.
+
+#### Protected Methods {#Test-protected}
+
+##### SetUp {#Test::SetUp}
+
+`virtual void Test::SetUp()`
+
+Override this to perform test fixture setup. GoogleTest calls `SetUp()` before
+running each individual test.
+
+##### TearDown {#Test::TearDown}
+
+`virtual void Test::TearDown()`
+
+Override this to perform test fixture teardown. GoogleTest calls `TearDown()`
+after running each individual test.
+
+### TestWithParam {#TestWithParam}
+
+`::testing::TestWithParam<T>`
+
+A convenience class which inherits from both [`Test`](#Test) and
+[`WithParamInterface<T>`](#WithParamInterface).
+
+### TestSuite {#TestSuite}

+
+Fired after the test suite ends.
+
+##### OnEnvironmentsTearDownStart {#TestEventListener::OnEnvironmentsTearDownStart}
+
+`virtual void TestEventListener::OnEnvironmentsTearDownStart(const UnitTest&
+unit_test)`
+

+
+##### Append {#TestEventListeners::Append}
+
+`void TestEventListeners::Append(TestEventListener* listener)`
+
+Appends an event listener to the end of the list. GoogleTest assumes ownership
+of the listener (i.e. it will delete the listener when the test program
+finishes).
+
+##### Release {#TestEventListeners::Release}
+
+`TestEventListener* TestEventListeners::Release(TestEventListener* listener)`
+
+Removes the given event listener from the list and returns it. It then becomes

+removed from the listeners list to shut down default console output. Note that
+removing this object from the listener list with
+[`Release()`](#TestEventListeners::Release) transfers its ownership to the
+caller and makes this function return `NULL` the next time.
+
+##### default_xml_generator {#TestEventListeners::default_xml_generator}
+
+`TestEventListener* TestEventListeners::default_xml_generator() const`
+
+Returns the standard listener responsible for the default XML output controlled
+by the `--gtest_output=xml` flag. Can be removed from the listeners list by
+users who want to shut down the default XML output controlled by this flag and
+substitute it with custom one. Note that removing this object from the listener
+list with [`Release()`](#TestEventListeners::Release) transfers its ownership to
+the caller and makes this function return `NULL` the next time.
+
+### TestPartResult {#TestPartResult}
+
+`::testing::TestPartResult`
+
+A copyable object representing the result of a test part (i.e. an assertion or
+an explicit `FAIL()`, `ADD_FAILURE()`, or `SUCCESS()`).

+Returns the [`TestPartResult`](#TestPartResult) for the `i`-th test part result
+among all the results. `i` can range from 0 to `total_part_count() - 1`. If `i`
+is not in that range, aborts the program.
+
+##### GetTestProperty {#TestResult::GetTestProperty}

+Represents a list of types for use in typed tests and type-parameterized tests.
+
+The template argument `T...` can be any number of types, for example:
+
+```
+::testing::Types<char, int, unsigned int>
+```
+
+See [Typed Tests](../advanced.md#typed-tests) and
+[Type-Parameterized Tests](../advanced.md#type-parameterized-tests) for more
+information.
+
+### WithParamInterface {#WithParamInterface}
+
+`::testing::WithParamInterface<T>`
+
+The pure interface class that all value-parameterized tests inherit from.
+
+A value-parameterized test fixture class must inherit from both [`Test`](#Test)
+and `WithParamInterface`. In most cases that just means inheriting from
+[`TestWithParam`](#TestWithParam), but more complicated test hierarchies may
+need to inherit from `Test` and `WithParamInterface` at different levels.
+
+This interface defines the type alias `ParamType` for the parameter type `T` and
+has support for accessing the test parameter value via the `GetParam()` method:
+
+```
+static const ParamType& GetParam()
+```
+
+For more information, see
+[Value-Parameterized Tests](../advanced.md#value-parameterized-tests).
+
+## Functions
+
+GoogleTest defines the following functions to help with writing and running
+tests.
+
+### InitGoogleTest {#InitGoogleTest}
+
+`void ::testing::InitGoogleTest(int* argc, char** argv)` \
+`void ::testing::InitGoogleTest(int* argc, wchar_t** argv)` \
+`void ::testing::InitGoogleTest()`
+
+Initializes GoogleTest. This must be called before calling
+[`RUN_ALL_TESTS()`](#RUN_ALL_TESTS). In particular, it parses the command line
+for the flags that GoogleTest recognizes. Whenever a GoogleTest flag is seen, it
+is removed from `argv`, and `*argc` is decremented.
+
+No value is returned. Instead, the GoogleTest flag variables are updated.
+
+The `InitGoogleTest(int* argc, wchar_t** argv)` overload can be used in Windows
+programs compiled in `UNICODE` mode.
+
+The argument-less `InitGoogleTest()` overload can be used on Arduino/embedded
+platforms where there is no `argc`/`argv`.
+
+### AddGlobalTestEnvironment {#AddGlobalTestEnvironment}
+
+`Environment* ::testing::AddGlobalTestEnvironment(Environment* env)`
+
+Adds a test environment to the test program. Must be called before
+[`RUN_ALL_TESTS()`](#RUN_ALL_TESTS) is called. See
+[Global Set-Up and Tear-Down](../advanced.md#global-set-up-and-tear-down) for
+more information.
+
+See also [`Environment`](#Environment).
+
+### RegisterTest {#RegisterTest}
+
+```cpp
+template <typename Factory>
+TestInfo* ::testing::RegisterTest(const char* test_suite_name, const char* test_name,
+ const char* type_param, const char* value_param,
+ const char* file, int line, Factory factory)
+```
+
+Dynamically registers a test with the framework.
+
+The `factory` argument is a factory callable (move-constructible) object or
+function pointer that creates a new instance of the `Test` object. It handles
+ownership to the caller. The signature of the callable is `Fixture*()`, where
+`Fixture` is the test fixture class for the test. All tests registered with the
+same `test_suite_name` must return the same fixture type. This is checked at
+runtime.
+
+The framework will infer the fixture class from the factory and will call the
+`SetUpTestSuite` and `TearDownTestSuite` methods for it.
+
+Must be called before [`RUN_ALL_TESTS()`](#RUN_ALL_TESTS) is invoked, otherwise
+behavior is undefined.
+
+See
+[Registering tests programmatically](../advanced.md#registering-tests-programmatically)
+for more information.
+
+### RUN_ALL_TESTS {#RUN_ALL_TESTS}
+
+`int RUN_ALL_TESTS()`
+
+Use this function in `main()` to run all tests. It returns `0` if all tests are
+successful, or `1` otherwise.
+
+`RUN_ALL_TESTS()` should be invoked after the command line has been parsed by
+[`InitGoogleTest()`](#InitGoogleTest).
+
+This function was formerly a macro; thus, it is in the global namespace and has
+an all-caps name.
+
+### AssertionSuccess {#AssertionSuccess}
+
+`AssertionResult ::testing::AssertionSuccess()`
+
+Creates a successful assertion result. See
+[`AssertionResult`](#AssertionResult).
+
+### AssertionFailure {#AssertionFailure}
+
+`AssertionResult ::testing::AssertionFailure()`
+
+Creates a failed assertion result. Use the `<<` operator to store a failure
+message:
+
+```cpp
+::testing::AssertionFailure() << "My failure message";
+```
+
+See [`AssertionResult`](#AssertionResult).
+
+### StaticAssertTypeEq {#StaticAssertTypeEq}
+
+`::testing::StaticAssertTypeEq<T1, T2>()`
+
+Compile-time assertion for type equality. Compiles if and only if `T1` and `T2`
+are the same type. The value it returns is irrelevant.
+
+See [Type Assertions](../advanced.md#type-assertions) for more information.
+
+### PrintToString {#PrintToString}
+
+`std::string ::testing::PrintToString(x)`
+
+Prints any value `x` using GoogleTest's value printer.
+
+See
+[Teaching GoogleTest How to Print Your Values](../advanced.md#teaching-googletest-how-to-print-your-values)
+for more information.
+
+### PrintToStringParamName {#PrintToStringParamName}
+
+`std::string ::testing::PrintToStringParamName(TestParamInfo<T>& info)`
+
+A built-in parameterized test name generator which returns the result of
+[`PrintToString`](#PrintToString) called on `info.param`. Does not work when the
+test parameter is a `std::string` or C string. See
+[Specifying Names for Value-Parameterized Test Parameters](../advanced.md#specifying-names-for-value-parameterized-test-parameters)
+for more information.
+
+See also [`TestParamInfo`](#TestParamInfo) and
+[`INSTANTIATE_TEST_SUITE_P`](#INSTANTIATE_TEST_SUITE_P).

+# Googletest Samples
+
+If you're like us, you'd like to look at
+[googletest samples.](https://github.com/google/googletest/tree/master/googletest/samples)
+The sample directory has a number of well-commented samples showing how to use a
+variety of googletest features.
+
+* Sample #1 shows the basic steps of using googletest to test C++ functions.
+* Sample #2 shows a more complex unit test for a class with multiple member
+ functions.
+* Sample #3 uses a test fixture.
+* Sample #4 teaches you how to use googletest and `googletest.h` together to
+ get the best of both libraries.
+* Sample #5 puts shared testing logic in a base test fixture, and reuses it in
+ derived fixtures.
+* Sample #6 demonstrates type-parameterized tests.
+* Sample #7 teaches the basics of value-parameterized tests.
+* Sample #8 shows using `Combine()` in value-parameterized tests.
+* Sample #9 shows use of the listener API to modify Google Test's console
+ output and the use of its reflection API to inspect test results.
+* Sample #10 shows use of the listener API to implement a primitive memory
+ leak checker.

+# Googletest Mocking (gMock) Framework
+
+### Overview
+
+Google's framework for writing and using C++ mock classes. It can help you
+derive better designs of your system and write better tests.
+
+It is inspired by:
+
+* [jMock](http://www.jmock.org/)
+* [EasyMock](http://www.easymock.org/)
+* [Hamcrest](http://code.google.com/p/hamcrest/)
+
+It is designed with C++'s specifics in mind.
+
+gMock:
+
+- Provides a declarative syntax for defining mocks.
+- Can define partial (hybrid) mocks, which are a cross of real and mock
+ objects.
+- Handles functions of arbitrary types and overloaded functions.
+- Comes with a rich set of matchers for validating function arguments.
+- Uses an intuitive syntax for controlling the behavior of a mock.
+- Does automatic verification of expectations (no record-and-replay needed).
+- Allows arbitrary (partial) ordering constraints on function calls to be
+ expressed.
+- Lets a user extend it by defining new matchers and actions.
+- Does not use exceptions.
+- Is easy to learn and use.
+
+Details and examples can be found here:
+
+* [gMock for Dummies](https://google.github.io/googletest/gmock_for_dummies.html)
+* [Legacy gMock FAQ](https://google.github.io/googletest/gmock_faq.html)
+* [gMock Cookbook](https://google.github.io/googletest/gmock_cook_book.html)
+* [gMock Cheat Sheet](https://google.github.io/googletest/gmock_cheat_sheet.html)
+
+GoogleMock is a part of
+[GoogleTest C++ testing framework](http://github.com/google/googletest/) and a
+subject to the same requirements.

+
+// Google Mock - a framework for writing C++ mock classes.
+//
+// The ACTION* family of macros can be used in a namespace scope to
+// define custom actions easily. The syntax:
+//
+// ACTION(name) { statements; }
+//
+// will define an action with the given name that executes the
+// statements. The value returned by the statements will be used as
+// the return value of the action. Inside the statements, you can
+// refer to the K-th (0-based) argument of the mock function by
+// 'argK', and refer to its type by 'argK_type'. For example:
+//
+// ACTION(IncrementArg1) {
+// arg1_type temp = arg1;
+// return ++(*temp);
+// }
+//
+// allows you to write
+//
+// ...WillOnce(IncrementArg1());
+//
+// You can also refer to the entire argument tuple and its type by
+// 'args' and 'args_type', and refer to the mock function type and its
+// return type by 'function_type' and 'return_type'.
+//
+// Note that you don't need to specify the types of the mock function
+// arguments. However rest assured that your code is still type-safe:
+// you'll get a compiler error if *arg1 doesn't support the ++
+// operator, or if the type of ++(*arg1) isn't compatible with the
+// mock function's return type, for example.
+//
+// Sometimes you'll want to parameterize the action. For that you can use
+// another macro:
+//
+// ACTION_P(name, param_name) { statements; }
+//
+// For example:
+//
+// ACTION_P(Add, n) { return arg0 + n; }
+//
+// will allow you to write:
+//
+// ...WillOnce(Add(5));
+//
+// Note that you don't need to provide the type of the parameter
+// either. If you need to reference the type of a parameter named
+// 'foo', you can write 'foo_type'. For example, in the body of
+// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
+// of 'n'.
+//
+// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P10 to support
+// multi-parameter actions.
+//
+// For the purpose of typing, you can view
+//
+// ACTION_Pk(Foo, p1, ..., pk) { ... }
+//
+// as shorthand for
+//
+// template <typename p1_type, ..., typename pk_type>
+// FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
+//
+// In particular, you can provide the template type arguments
+// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
+// although usually you can rely on the compiler to infer the types
+// for you automatically. You can assign the result of expression
+// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
+// pk_type>. This can be useful when composing actions.
+//
+// You can also overload actions with different numbers of parameters:
+//
+// ACTION_P(Plus, a) { ... }
+// ACTION_P2(Plus, a, b) { ... }
+//
+// While it's tempting to always use the ACTION* macros when defining
+// a new action, you should also consider implementing ActionInterface
+// or using MakePolymorphicAction() instead, especially if you need to
+// use the action a lot. While these approaches require more work,
+// they give you more control on the types of the mock function
+// arguments and the action parameters, which in general leads to
+// better compiler error messages that pay off in the long run. They
+// also allow overloading actions based on parameter types (as opposed
+// to just based on the number of parameters).
+//
+// CAVEAT:
+//
+// ACTION*() can only be used in a namespace scope as templates cannot be
+// declared inside of a local class.
+// Users can, however, define any local functors (e.g. a lambda) that
+// can be used as actions.
+//
+// MORE INFORMATION:
+//

+
+// Google Mock - a framework for writing C++ mock classes.
+//
+// The MATCHER* family of macros can be used in a namespace scope to
+// define custom matchers easily.
+//
+// Basic Usage
+// ===========
+//
+// The syntax
+//
+// MATCHER(name, description_string) { statements; }
+//
+// defines a matcher with the given name that executes the statements,
+// which must return a bool to indicate if the match succeeds. Inside
+// the statements, you can refer to the value being matched by 'arg',
+// and refer to its type by 'arg_type'.
+//
+// The description string documents what the matcher does, and is used
+// to generate the failure message when the match fails. Since a
+// MATCHER() is usually defined in a header file shared by multiple
+// C++ source files, we require the description to be a C-string
+// literal to avoid possible side effects. It can be empty, in which
+// case we'll use the sequence of words in the matcher name as the
+// description.
+//
+// For example:
+//
+// MATCHER(IsEven, "") { return (arg % 2) == 0; }
+//
+// allows you to write
+//
+// // Expects mock_foo.Bar(n) to be called where n is even.
+// EXPECT_CALL(mock_foo, Bar(IsEven()));
+//
+// or,
+//
+// // Verifies that the value of some_expression is even.
+// EXPECT_THAT(some_expression, IsEven());
+//
+// If the above assertion fails, it will print something like:
+//
+// Value of: some_expression
+// Expected: is even
+// Actual: 7
+//
+// where the description "is even" is automatically calculated from the
+// matcher name IsEven.
+//
+// Argument Type
+// =============
+//
+// Note that the type of the value being matched (arg_type) is
+// determined by the context in which you use the matcher and is
+// supplied to you by the compiler, so you don't need to worry about
+// declaring it (nor can you). This allows the matcher to be
+// polymorphic. For example, IsEven() can be used to match any type
+// where the value of "(arg % 2) == 0" can be implicitly converted to
+// a bool. In the "Bar(IsEven())" example above, if method Bar()
+// takes an int, 'arg_type' will be int; if it takes an unsigned long,
+// 'arg_type' will be unsigned long; and so on.
+//
+// Parameterizing Matchers
+// =======================
+//
+// Sometimes you'll want to parameterize the matcher. For that you
+// can use another macro:
+//
+// MATCHER_P(name, param_name, description_string) { statements; }
+//
+// For example:
+//
+// MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
+//
+// will allow you to write:
+//
+// EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
+//
+// which may lead to this message (assuming n is 10):
+//
+// Value of: Blah("a")
+// Expected: has absolute value 10
+// Actual: -9
+//
+// Note that both the matcher description and its parameter are
+// printed, making the message human-friendly.
+//
+// In the matcher definition body, you can write 'foo_type' to
+// reference the type of a parameter named 'foo'. For example, in the
+// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
+// 'value_type' to refer to the type of 'value'.
+//
+// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P$n to
+// support multi-parameter matchers.
+//
+// Describing Parameterized Matchers
+// =================================
+//
+// The last argument to MATCHER*() is a string-typed expression. The
+// expression can reference all of the matcher's parameters and a
+// special bool-typed variable named 'negation'. When 'negation' is
+// false, the expression should evaluate to the matcher's description;
+// otherwise it should evaluate to the description of the negation of
+// the matcher. For example,
+//
+// using testing::PrintToString;
+//
+// MATCHER_P2(InClosedRange, low, hi,
+// std::string(negation ? "is not" : "is") + " in range [" +
+// PrintToString(low) + ", " + PrintToString(hi) + "]") {
+// return low <= arg && arg <= hi;
+// }
+// ...
+// EXPECT_THAT(3, InClosedRange(4, 6));
+// EXPECT_THAT(3, Not(InClosedRange(2, 4)));
+//
+// would generate two failures that contain the text:
+//
+// Expected: is in range [4, 6]
+// ...
+// Expected: is not in range [2, 4]
+//
+// If you specify "" as the description, the failure message will
+// contain the sequence of words in the matcher name followed by the
+// parameter values printed as a tuple. For example,
+//
+// MATCHER_P2(InClosedRange, low, hi, "") { ... }
+// ...
+// EXPECT_THAT(3, InClosedRange(4, 6));
+// EXPECT_THAT(3, Not(InClosedRange(2, 4)));
+//
+// would generate two failures that contain the text:
+//
+// Expected: in closed range (4, 6)
+// ...
+// Expected: not (in closed range (2, 4))
+//
+// Types of Matcher Parameters
+// ===========================
+//
+// For the purpose of typing, you can view
+//
+// MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
+//
+// as shorthand for
+//
+// template <typename p1_type, ..., typename pk_type>
+// FooMatcherPk<p1_type, ..., pk_type>
+// Foo(p1_type p1, ..., pk_type pk) { ... }
+//
+// When you write Foo(v1, ..., vk), the compiler infers the types of
+// the parameters v1, ..., and vk for you. If you are not happy with
+// the result of the type inference, you can specify the types by
+// explicitly instantiating the template, as in Foo<long, bool>(5,
+// false). As said earlier, you don't get to (or need to) specify
+// 'arg_type' as that's determined by the context in which the matcher
+// is used. You can assign the result of expression Foo(p1, ..., pk)
+// to a variable of type FooMatcherPk<p1_type, ..., pk_type>. This
+// can be useful when composing matchers.
+//
+// While you can instantiate a matcher template with reference types,
+// passing the parameters by pointer usually makes your code more
+// readable. If, however, you still want to pass a parameter by
+// reference, be aware that in the failure message generated by the
+// matcher you will see the value of the referenced object but not its
+// address.
+//
+// Explaining Match Results
+// ========================
+//
+// Sometimes the matcher description alone isn't enough to explain why
+// the match has failed or succeeded. For example, when expecting a
+// long string, it can be very helpful to also print the diff between
+// the expected string and the actual one. To achieve that, you can
+// optionally stream additional information to a special variable
+// named result_listener, whose type is a pointer to class
+// MatchResultListener:
+//
+// MATCHER_P(EqualsLongString, str, "") {
+// if (arg == str) return true;
+//
+// *result_listener << "the difference: "
+/// << DiffStrings(str, arg);
+// return false;
+// }
+//
+// Overloading Matchers
+// ====================
+//
+// You can overload matchers with different numbers of parameters:
+//
+// MATCHER_P(Blah, a, description_string1) { ... }
+// MATCHER_P2(Blah, a, b, description_string2) { ... }
+//
+// Caveats
+// =======
+//
+// When defining a new matcher, you should also consider implementing
+// MatcherInterface or using MakePolymorphicMatcher(). These
+// approaches require more work than the MATCHER* macros, but also
+// give you more control on the types of the value being matched and
+// the matcher parameters, which may leads to better compiler error
+// messages when the matcher is used wrong. They also allow
+// overloading matchers based on parameter types (as opposed to just
+// based on the number of parameters).
+//
+// MATCHER*() can only be used in a namespace scope as templates cannot be
+// declared inside of a local class.
+//
+// More Information
+// ================
+//
+// To learn more about using these macros, please search for 'MATCHER'
+// on
+// https://github.com/google/googletest/blob/master/docs/gmock_cook_book.md
+//
+// This file also implements some commonly used argument matchers. More
+// matchers can be defined by the user implementing the
+// MatcherInterface<T> interface if necessary.
+//
+// See googletest/include/gtest/gtest-matchers.h for the definition of class
+// Matcher, class MatcherInterface, and others.

+
+// Sometimes you want to give an action explicit template parameters
+// that cannot be inferred from its value parameters. ACTION() and
+// ACTION_P*() don't support that. ACTION_TEMPLATE() remedies that
+// and can be viewed as an extension to ACTION() and ACTION_P*().
+//
+// The syntax:
+//
+// ACTION_TEMPLATE(ActionName,
+// HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
+// AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
+//
+// defines an action template that takes m explicit template
+// parameters and n value parameters. name_i is the name of the i-th
+// template parameter, and kind_i specifies whether it's a typename,
+// an integral constant, or a template. p_i is the name of the i-th
+// value parameter.
+//
+// Example:
+//
+// // DuplicateArg<k, T>(output) converts the k-th argument of the mock
+// // function to type T and copies it to *output.
+// ACTION_TEMPLATE(DuplicateArg,
+// HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
+// AND_1_VALUE_PARAMS(output)) {
+// *output = T(::std::get<k>(args));
+// }
+// ...
+// int n;
+// EXPECT_CALL(mock, Foo(_, _))
+// .WillOnce(DuplicateArg<1, unsigned char>(&n));
+//
+// To create an instance of an action template, write:
+//
+// ActionName<t1, ..., t_m>(v1, ..., v_n)
+//
+// where the ts are the template arguments and the vs are the value
+// arguments. The value argument types are inferred by the compiler.
+// If you want to explicitly specify the value argument types, you can
+// provide additional template arguments:
+//
+// ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
+//
+// where u_i is the desired type of v_i.
+//
+// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
+// number of value parameters, but not on the number of template
+// parameters. Without the restriction, the meaning of the following
+// is unclear:
+//
+// OverloadedAction<int, bool>(x);
+//
+// Are we using a single-template-parameter action where 'bool' refers
+// to the type of x, or are we using a two-template-parameter action
+// where the compiler is asked to infer the type of x?
+//
+// Implementation notes:
+//
+// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
+// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
+// implementing ACTION_TEMPLATE. The main trick we use is to create
+// new macro invocations when expanding a macro. For example, we have
+//
+// #define ACTION_TEMPLATE(name, template_params, value_params)
+// ... GMOCK_INTERNAL_DECL_##template_params ...
+//
+// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
+// to expand to
+//
+// ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
+//
+// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
+// preprocessor will continue to expand it to
+//
+// ... typename T ...
+//
+// This technique conforms to the C++ standard and is portable. It
+// allows us to implement action templates using O(N) code, where N is
+// the maximum number of template/value parameters supported. Without
+// using it, we'd have to devote O(N^2) amount of code to implement all
+// combinations of m and n.
+
+// Declares the template parameters.

+// Implements class templates NiceMock, NaggyMock, and StrictMock.
+//
+// Given a mock class MockFoo that is created using Google Mock,
+// NiceMock<MockFoo> is a subclass of MockFoo that allows
+// uninteresting calls (i.e. calls to mock methods that have no
+// EXPECT_CALL specs), NaggyMock<MockFoo> is a subclass of MockFoo
+// that prints a warning when an uninteresting call occurs, and
+// StrictMock<MockFoo> is a subclass of MockFoo that treats all
+// uninteresting calls as errors.
+//
+// Currently a mock is naggy by default, so MockFoo and
+// NaggyMock<MockFoo> behave like the same. However, we will soon
+// switch the default behavior of mocks to be nice, as that in general
+// leads to more maintainable tests. When that happens, MockFoo will
+// stop behaving like NaggyMock<MockFoo> and start behaving like
+// NiceMock<MockFoo>.
+//
+// NiceMock, NaggyMock, and StrictMock "inherit" the constructors of
+// their respective base class. Therefore you can write
+// NiceMock<MockFoo>(5, "a") to construct a nice mock where MockFoo
+// has a constructor that accepts (int, const char*), for example.
+//
+// A known limitation is that NiceMock<MockFoo>, NaggyMock<MockFoo>,
+// and StrictMock<MockFoo> only works for mock methods defined using
+// the MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.
+// If a mock method is defined in a base class of MockFoo, the "nice"
+// or "strict" modifier may not affect it, depending on the compiler.
+// In particular, nesting NiceMock, NaggyMock, and StrictMock is NOT
+// supported.

+
+// A MockFunction<F> type has one mock method whose type is
+// internal::SignatureOfT<F>. It is useful when you just want your
+// test code to emit some messages and have Google Mock verify the
+// right messages are sent (and perhaps at the right times). For
+// example, if you are exercising code:
+//
+// Foo(1);
+// Foo(2);
+// Foo(3);
+//
+// and want to verify that Foo(1) and Foo(3) both invoke
+// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
+//
+// TEST(FooTest, InvokesBarCorrectly) {
+// MyMock mock;
+// MockFunction<void(string check_point_name)> check;
+// {
+// InSequence s;
+//
+// EXPECT_CALL(mock, Bar("a"));
+// EXPECT_CALL(check, Call("1"));
+// EXPECT_CALL(check, Call("2"));
+// EXPECT_CALL(mock, Bar("a"));
+// }
+// Foo(1);
+// check.Call("1");
+// Foo(2);
+// check.Call("2");
+// Foo(3);
+// }
+//
+// The expectation spec says that the first Bar("a") must happen
+// before check point "1", the second Bar("a") must happen after check
+// point "2", and nothing should happen between the two check
+// points. The explicit check points make it easy to tell which
+// Bar("a") is called by which call to Foo().
+//
+// MockFunction<F> can also be used to exercise code that accepts
+// std::function<internal::SignatureOfT<F>> callbacks. To do so, use
+// AsStdFunction() method to create std::function proxy forwarding to
+// original object's Call. Example:
+//
+// TEST(FooTest, RunsCallbackWithBarArgument) {
+// MockFunction<int(string)> callback;
+// EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
+// Foo(callback.AsStdFunction());
+// }
+//
+// The internal::SignatureOfT<F> indirection allows to use other types
+// than just function signature type. This is typically useful when
+// providing a mock for a predefined std::function type. Example:
+//
+// using FilterPredicate = std::function<bool(string)>;
+// void MyFilterAlgorithm(FilterPredicate predicate);
+//
+// TEST(FooTest, FilterPredicateAlwaysAccepts) {
+// MockFunction<FilterPredicate> predicateMock;
+// EXPECT_CALL(predicateMock, Call(_)).WillRepeatedly(Return(true));
+// MyFilterAlgorithm(predicateMock.AsStdFunction());
+// }

+// Implementation for ON_CALL and EXPECT_CALL macros. A separate macro is
+// required to avoid compile errors when the name of the method used in call is
+// a result of macro expansion. See CompilesWithMethodNameExpandedFromMacro
+// tests in internal/gmock-spec-builders_test.cc for more details.
+//
+// This macro supports statements both with and without parameter matchers. If
+// the parameter list is omitted, gMock will accept any parameters, which allows
+// tests to be written that don't need to encode the number of method
+// parameter. This technique may only be used for non-overloaded methods.
+//
+// // These are the same:
+// ON_CALL(mock, NoArgsMethod()).WillByDefault(...);
+// ON_CALL(mock, NoArgsMethod).WillByDefault(...);
+//
+// // As are these:
+// ON_CALL(mock, TwoArgsMethod(_, _)).WillByDefault(...);
+// ON_CALL(mock, TwoArgsMethod).WillByDefault(...);
+//
+// // Can also specify args if you want, of course:
+// ON_CALL(mock, TwoArgsMethod(_, 45)).WillByDefault(...);
+//
+// // Overloads work as long as you specify parameters:
+// ON_CALL(mock, OverloadedMethod(_)).WillByDefault(...);
+// ON_CALL(mock, OverloadedMethod(_, _)).WillByDefault(...);
+//
+// // Oops! Which overload did you want?
+// ON_CALL(mock, OverloadedMethod).WillByDefault(...);
+// => ERROR: call to member function 'gmock_OverloadedMethod' is ambiguous
+//
+// How this works: The mock class uses two overloads of the gmock_Method
+// expectation setter method plus an operator() overload on the MockSpec object.
+// In the matcher list form, the macro expands to:
+//
+// // This statement:
+// ON_CALL(mock, TwoArgsMethod(_, 45))...
+//
+// // ...expands to:
+// mock.gmock_TwoArgsMethod(_, 45)(WithoutMatchers(), nullptr)...
+// |-------------v---------------||------------v-------------|
+// invokes first overload swallowed by operator()
+//
+// // ...which is essentially:
+// mock.gmock_TwoArgsMethod(_, 45)...
+//
+// Whereas the form without a matcher list:
+//
+// // This statement:
+// ON_CALL(mock, TwoArgsMethod)...
+//
+// // ...expands to:
+// mock.gmock_TwoArgsMethod(WithoutMatchers(), nullptr)...
+// |-----------------------v--------------------------|
+// invokes second overload
+//
+// // ...which is essentially:
+// mock.gmock_TwoArgsMethod(_, _)...
+//
+// The WithoutMatchers() argument is used to disambiguate overloads and to
+// block the caller from accidentally invoking the second overload directly. The
+// second argument is an internal type derived from the method signature. The
+// failure to disambiguate two overloads of this method in the ON_CALL statement
+// is how we block callers from setting expectations on overloaded methods.

+// FindMaxBipartiteMatching and its helper class.
+//
+// Uses the well-known Ford-Fulkerson max flow method to find a maximum
+// bipartite matching. Flow is considered to be from left to right.
+// There is an implicit source node that is connected to all of the left
+// nodes, and an implicit sink node that is connected to all of the
+// right nodes. All edges have unit capacity.
+//
+// Neither the flow graph nor the residual flow graph are represented
+// explicitly. Instead, they are implied by the information in 'graph' and
+// a vector<int> called 'left_' whose elements are initialized to the
+// value kUnused. This represents the initial state of the algorithm,
+// where the flow graph is empty, and the residual flow graph has the
+// following edges:
+// - An edge from source to each left_ node
+// - An edge from each right_ node to sink
+// - An edge from each left_ node to each right_ node, if the
+// corresponding edge exists in 'graph'.
+//
+// When the TryAugment() method adds a flow, it sets left_[l] = r for some
+// nodes l and r. This induces the following changes:
+// - The edges (source, l), (l, r), and (r, sink) are added to the
+// flow graph.
+// - The same three edges are removed from the residual flow graph.
+// - The reverse edges (l, source), (r, l), and (sink, r) are added
+// to the residual flow graph, which is a directional graph
+// representing unused flow capacity.
+//
+// When the method augments a flow (moving left_[l] from some r1 to some
+// other r2), this can be thought of as "undoing" the above steps with
+// respect to r1 and "redoing" them with respect to r2.
+//
+// It bears repeating that the flow graph and residual flow graph are
+// never represented explicitly, but can be derived by looking at the
+// information in 'graph' and in left_.
+//
+// As an optimization, there is a second vector<int> called right_ which
+// does not provide any new information. Instead, it enables more
+// efficient queries about edges entering or leaving the right-side nodes
+// of the flow or residual flow graphs. The following invariants are
+// maintained:

+// Please note: this test does not verify the functioning of these
+// constructs, only that the programs using them will link successfully.
+//
+// Implementation note:
+// This test requires identical definitions of Interface and Mock to be
+// included in different translation units. We achieve this by writing
+// them in this header and #including it in gmock_link_test.cc and
+// gmock_link2_test.cc. Because the symbols generated by the compiler for
+// those constructs must be identical in both translation units,
+// definitions of Interface and Mock tests MUST be kept in the SAME
+// NON-ANONYMOUS namespace in this file. The test fixture class LinkTest
+// is defined as LinkTest1 in gmock_link_test.cc and as LinkTest2 in
+// gmock_link2_test.cc to avoid producing linker errors.

+### Generic Build Instructions
+
+#### Setup
+
+To build GoogleTest and your tests that use it, you need to tell your build
+system where to find its headers and source files. The exact way to do it
+depends on which build system you use, and is usually straightforward.
+
+### Build with CMake
+
+GoogleTest comes with a CMake build script
+([CMakeLists.txt](https://github.com/google/googletest/blob/master/CMakeLists.txt))
+that can be used on a wide range of platforms ("C" stands for cross-platform.).
+If you don't have CMake installed already, you can download it for free from
+<http://www.cmake.org/>.
+
+CMake works by generating native makefiles or build projects that can be used in
+the compiler environment of your choice. You can either build GoogleTest as a
+standalone project or it can be incorporated into an existing CMake build for
+another project.
+
+#### Standalone CMake Project
+
+When building GoogleTest as a standalone project, the typical workflow starts
+with
+
+```
+git clone https://github.com/google/googletest.git -b release-1.11.0
+cd googletest # Main directory of the cloned repository.
+mkdir build # Create a directory to hold the build output.
+cd build
+cmake .. # Generate native build scripts for GoogleTest.
+```
+
+The above command also includes GoogleMock by default. And so, if you want to
+build only GoogleTest, you should replace the last command with
+
+```
+cmake .. -DBUILD_GMOCK=OFF
+```
+
+If you are on a \*nix system, you should now see a Makefile in the current
+directory. Just type `make` to build GoogleTest. And then you can simply install
+GoogleTest if you are a system administrator.
+
+```
+make
+sudo make install # Install in /usr/local/ by default
+```
+
+If you use Windows and have Visual Studio installed, a `gtest.sln` file and
+several `.vcproj` files will be created. You can then build them using Visual
+Studio.
+
+On Mac OS X with Xcode installed, a `.xcodeproj` file will be generated.
+
+#### Incorporating Into An Existing CMake Project
+
+If you want to use GoogleTest in a project which already uses CMake, the easiest
+way is to get installed libraries and headers.
+
+* Import GoogleTest by using `find_package` (or `pkg_check_modules`). For
+ example, if `find_package(GTest CONFIG REQUIRED)` succeeds, you can use the
+ libraries as `GTest::gtest`, `GTest::gmock`.
+
+And a more robust and flexible approach is to build GoogleTest as part of that
+project directly. This is done by making the GoogleTest source code available to
+the main build and adding it using CMake's `add_subdirectory()` command. This
+has the significant advantage that the same compiler and linker settings are
+used between GoogleTest and the rest of your project, so issues associated with
+using incompatible libraries (eg debug/release), etc. are avoided. This is
+particularly useful on Windows. Making GoogleTest's source code available to the
+main build can be done a few different ways:
+
+* Download the GoogleTest source code manually and place it at a known
+ location. This is the least flexible approach and can make it more difficult
+ to use with continuous integration systems, etc.
+* Embed the GoogleTest source code as a direct copy in the main project's
+ source tree. This is often the simplest approach, but is also the hardest to
+ keep up to date. Some organizations may not permit this method.
+* Add GoogleTest as a git submodule or equivalent. This may not always be
+ possible or appropriate. Git submodules, for example, have their own set of
+ advantages and drawbacks.
+* Use CMake to download GoogleTest as part of the build's configure step. This
+ approach doesn't have the limitations of the other methods.
+
+The last of the above methods is implemented with a small piece of CMake code
+that downloads and pulls the GoogleTest code into the main build.
+
+Just add to your `CMakeLists.txt`:
+
+```cmake
+include(FetchContent)
+FetchContent_Declare(
+ googletest
+ # Specify the commit you depend on and update it regularly.
+ URL https://github.com/google/googletest/archive/609281088cfefc76f9d0ce82e1ff6c30cc3591e5.zip
+)
+# For Windows: Prevent overriding the parent project's compiler/linker settings
+set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
+FetchContent_MakeAvailable(googletest)
+
+# Now simply link against gtest or gtest_main as needed. Eg
+add_executable(example example.cpp)
+target_link_libraries(example gtest_main)
+add_test(NAME example_test COMMAND example)
+```
+
+Note that this approach requires CMake 3.14 or later due to its use of the
+`FetchContent_MakeAvailable()` command.
+
+##### Visual Studio Dynamic vs Static Runtimes
+
+By default, new Visual Studio projects link the C runtimes dynamically but
+GoogleTest links them statically. This will generate an error that looks
+something like the following: gtest.lib(gtest-all.obj) : error LNK2038: mismatch
+detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value
+'MDd_DynamicDebug' in main.obj
+
+GoogleTest already has a CMake option for this: `gtest_force_shared_crt`
+
+Enabling this option will make gtest link the runtimes dynamically too, and
+match the project in which it is included.
+
+#### C++ Standard Version
+
+An environment that supports C++11 is required in order to successfully build
+GoogleTest. One way to ensure this is to specify the standard in the top-level
+project, for example by using the `set(CMAKE_CXX_STANDARD 11)` command. If this
+is not feasible, for example in a C project using GoogleTest for validation,
+then it can be specified by adding it to the options for cmake via the
+`DCMAKE_CXX_FLAGS` option.
+
+### Tweaking GoogleTest
+
+GoogleTest can be used in diverse environments. The default configuration may
+not work (or may not work well) out of the box in some environments. However,
+you can easily tweak GoogleTest by defining control macros on the compiler
+command line. Generally, these macros are named like `GTEST_XYZ` and you define
+them to either 1 or 0 to enable or disable a certain feature.
+
+We list the most frequently used macros below. For a complete list, see file
+[include/gtest/internal/gtest-port.h](https://github.com/google/googletest/blob/master/googletest/include/gtest/internal/gtest-port.h).
+
+### Multi-threaded Tests
+
+GoogleTest is thread-safe where the pthread library is available. After
+`#include "gtest/gtest.h"`, you can check the
+`GTEST_IS_THREADSAFE` macro to see whether this is the case (yes if the macro is
+`#defined` to 1, no if it's undefined.).
+
+If GoogleTest doesn't correctly detect whether pthread is available in your
+environment, you can force it with
+
+ -DGTEST_HAS_PTHREAD=1
+
+or
+
+ -DGTEST_HAS_PTHREAD=0
+
+When GoogleTest uses pthread, you may need to add flags to your compiler and/or
+linker to select the pthread library, or you'll get link errors. If you use the
+CMake script, this is taken care of for you. If you use your own build script,
+you'll need to read your compiler and linker's manual to figure out what flags
+to add.
+
+### As a Shared Library (DLL)
+
+GoogleTest is compact, so most users can build and link it as a static library
+for the simplicity. You can choose to use GoogleTest as a shared library (known
+as a DLL on Windows) if you prefer.
+
+To compile *gtest* as a shared library, add
+
+ -DGTEST_CREATE_SHARED_LIBRARY=1
+
+to the compiler flags. You'll also need to tell the linker to produce a shared
+library instead - consult your linker's manual for how to do it.
+
+To compile your *tests* that use the gtest shared library, add
+
+ -DGTEST_LINKED_AS_SHARED_LIBRARY=1
+
+to the compiler flags.
+
+Note: while the above steps aren't technically necessary today when using some
+compilers (e.g. GCC), they may become necessary in the future, if we decide to
+improve the speed of loading the library (see
+<http://gcc.gnu.org/wiki/Visibility> for details). Therefore you are recommended
+to always add the above flags when using GoogleTest as a shared library.
+Otherwise a future release of GoogleTest may break your build script.
+
+### Avoiding Macro Name Clashes
+
+In C++, macros don't obey namespaces. Therefore two libraries that both define a
+macro of the same name will clash if you `#include` both definitions. In case a
+GoogleTest macro clashes with another library, you can force GoogleTest to
+rename its macro to avoid the conflict.
+
+Specifically, if both GoogleTest and some other code define macro FOO, you can
+add
+
+ -DGTEST_DONT_DEFINE_FOO=1
+
+to the compiler flags to tell GoogleTest to change the macro's name from `FOO`
+to `GTEST_FOO`. Currently `FOO` can be `ASSERT_EQ`, `ASSERT_FALSE`, `ASSERT_GE`,
+`ASSERT_GT`, `ASSERT_LE`, `ASSERT_LT`, `ASSERT_NE`, `ASSERT_TRUE`,
+`EXPECT_FALSE`, `EXPECT_TRUE`, `FAIL`, `SUCCEED`, `TEST`, or `TEST_F`. For
+example, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll need to write
+
+ GTEST_TEST(SomeTest, DoesThis) { ... }
+
+instead of
+
+ TEST(SomeTest, DoesThis) { ... }
+
+in order to define a test.

+// A class for indicating whether an assertion was successful. When
+// the assertion wasn't successful, the AssertionResult object
+// remembers a non-empty message that describes how it failed.
+//
+// To create an instance of this class, use one of the factory functions
+// (AssertionSuccess() and AssertionFailure()).
+//
+// This class is useful for two purposes:
+// 1. Defining predicate functions to be used with Boolean test assertions
+// EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts
+// 2. Defining predicate-format functions to be
+// used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
+//
+// For example, if you define IsEven predicate:
+//
+// testing::AssertionResult IsEven(int n) {
+// if ((n % 2) == 0)
+// return testing::AssertionSuccess();
+// else
+// return testing::AssertionFailure() << n << " is odd";
+// }
+//
+// Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
+// will print the message
+//
+// Value of: IsEven(Fib(5))
+// Actual: false (5 is odd)
+// Expected: true
+//
+// instead of a more opaque
+//
+// Value of: IsEven(Fib(5))
+// Actual: false
+// Expected: true
+//
+// in case IsEven is a simple Boolean predicate.
+//
+// If you expect your predicate to be reused and want to support informative
+// messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
+// about half as often as positive ones in our tests), supply messages for
+// both success and failure cases:
+//
+// testing::AssertionResult IsEven(int n) {
+// if ((n % 2) == 0)
+// return testing::AssertionSuccess() << n << " is even";
+// else
+// return testing::AssertionFailure() << n << " is odd";
+// }
+//
+// Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
+//
+// Value of: IsEven(Fib(6))
+// Actual: true (8 is even)
+// Expected: false
+//
+// NB: Predicates that support negative Boolean assertions have reduced
+// performance in positive ones so be careful not to use them in tests
+// that have lots (tens of thousands) of positive Boolean assertions.
+//
+// To use this class with EXPECT_PRED_FORMAT assertions such as:
+//
+// // Verifies that Foo() returns an even number.
+// EXPECT_PRED_FORMAT1(IsEven, Foo());
+//
+// you need to define:
+//
+// testing::AssertionResult IsEven(const char* expr, int n) {
+// if ((n % 2) == 0)
+// return testing::AssertionSuccess();
+// else
+// return testing::AssertionFailure()
+// << "Expected: " << expr << " is even\n Actual: it's " << n;
+// }
+//
+// If Foo() returns 5, you will see the following message:
+//
+// Expected: Foo() is even
+// Actual: it's 5

+// The final parameter to each of these macros is a matcher applied to any data
+// the sub-process wrote to stderr. For compatibility with existing tests, a
+// bare string is interpreted as a regular expression matcher.
+//
+// On the regular expressions used in death tests:
+//
+// On POSIX-compliant systems (*nix), we use the <regex.h> library,
+// which uses the POSIX extended regex syntax.
+//
+// On other platforms (e.g. Windows or Mac), we only support a simple regex
+// syntax implemented as part of Google Test. This limited
+// implementation should be enough most of the time when writing
+// death tests; though it lacks many features you can find in PCRE
+// or POSIX extended regex syntax. For example, we don't support
+// union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
+// repetition count ("x{5,7}"), among others.
+//
+// Below is the syntax that we do support. We chose it to be a
+// subset of both PCRE and POSIX extended regex, so it's easy to
+// learn wherever you come from. In the following: 'A' denotes a
+// literal character, period (.), or a single \\ escape sequence;
+// 'x' and 'y' denote regular expressions; 'm' and 'n' are for
+// natural numbers.
+//
+// c matches any literal character c
+// \\d matches any decimal digit
+// \\D matches any character that's not a decimal digit
+// \\f matches \f
+// \\n matches \n
+// \\r matches \r
+// \\s matches any ASCII whitespace, including \n
+// \\S matches any character that's not a whitespace
+// \\t matches \t
+// \\v matches \v
+// \\w matches any letter, _, or decimal digit
+// \\W matches any character that \\w doesn't match
+// \\c matches any literal character c, which must be a punctuation
+// . matches any single character except \n
+// A? matches 0 or 1 occurrences of A
+// A* matches 0 or many occurrences of A
+// A+ matches 1 or many occurrences of A
+// ^ matches the beginning of a string (not that of each line)
+// $ matches the end of a string (not that of each line)
+// xy matches x followed by y
+//
+// If you accidentally use PCRE or POSIX extended regex features
+// not implemented by us, you will get a run-time failure. In that
+// case, please try to rewrite your regular expression within the
+// above syntax.
+//
+// This implementation is *not* meant to be as highly tuned or robust
+// as a compiled regex library, but should perform well enough for a
+// death test, which already incurs significant overhead by launching
+// a child process.
+//
+// Known caveats:
+//
+// A "threadsafe" style death test obtains the path to the test
+// program from argv[0] and re-executes it in the sub-process. For
+// simplicity, the current implementation doesn't search the PATH
+// when launching the sub-process. This means that the user must
+// invoke the test program via a path that contains at least one
+// path separator (e.g. path/to/foo_test and
+// /absolute/path/to/bar_test are fine, but foo_test is not). This
+// is rarely a problem as people usually don't put the test binary
+// directory in PATH.

+// This macro is used for implementing macros such as

+// that have death-tests with stricter requirements than GTEST_HAS_DEATH_TEST
+// can write their own equivalent of EXPECT_DEATH_IF_SUPPORTED and

+//
+// Parameters:
+// statement - A statement that a macro such as EXPECT_DEATH would test
+// for program termination. This macro has to make sure this
+// statement is compiled but not executed, to ensure that
+// EXPECT_DEATH_IF_SUPPORTED compiles with a certain
+// parameter if and only if EXPECT_DEATH compiles with it.
+// regex - A regex that a macro such as EXPECT_DEATH would use to test
+// the output of statement. This parameter has to be
+// compiled but not evaluated by this macro, to ensure that
+// this macro only accepts expressions that a macro such as
+// EXPECT_DEATH would accept.
+// terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
+// and a return statement for ASSERT_DEATH_IF_SUPPORTED.
+// This ensures that ASSERT_DEATH_IF_SUPPORTED will not
+// compile inside functions where ASSERT_DEATH doesn't
+// compile.
+//
+// The branch that has an always false condition is used to ensure that

+// never executed. The unreachable code macro protects the terminator
+// statement from generating an 'unreachable code' warning in case

+// Value-parameterized tests allow you to test your code with different
+// parameters without writing multiple copies of the same test.
+//
+// Here is how you use value-parameterized tests:
+
+#if 0
+
+// To write value-parameterized tests, first you should define a fixture
+// class. It is usually derived from testing::TestWithParam<T> (see below for
+// another inheritance scheme that's sometimes useful in more complicated
+// class hierarchies), where the type of your parameter values.
+// TestWithParam<T> is itself derived from testing::Test. T can be any
+// copyable type. If it's a raw pointer, you are responsible for managing the
+// lifespan of the pointed values.
+
+class FooTest : public ::testing::TestWithParam<const char*> {
+ // You can implement all the usual class fixture members here.
+};
+
+// Then, use the TEST_P macro to define as many parameterized tests
+// for this fixture as you want. The _P suffix is for "parameterized"
+// or "pattern", whichever you prefer to think.
+
+TEST_P(FooTest, DoesBlah) {
+ // Inside a test, access the test parameter with the GetParam() method
+ // of the TestWithParam<T> class:
+ EXPECT_TRUE(foo.Blah(GetParam()));
+ ...
+}
+
+TEST_P(FooTest, HasBlahBlah) {
+ ...
+}
+
+// Finally, you can use INSTANTIATE_TEST_SUITE_P to instantiate the test
+// case with any set of parameters you want. Google Test defines a number
+// of functions for generating test parameters. They return what we call
+// (surprise!) parameter generators. Here is a summary of them, which
+// are all in the testing namespace:
+//
+//
+// Range(begin, end [, step]) - Yields values {begin, begin+step,
+// begin+step+step, ...}. The values do not
+// include end. step defaults to 1.
+// Values(v1, v2, ..., vN) - Yields values {v1, v2, ..., vN}.
+// ValuesIn(container) - Yields values from a C-style array, an STL
+// ValuesIn(begin,end) container, or an iterator range [begin, end).
+// Bool() - Yields sequence {false, true}.
+// Combine(g1, g2, ..., gN) - Yields all combinations (the Cartesian product
+// for the math savvy) of the values generated
+// by the N generators.
+//
+// For more details, see comments at the definitions of these functions below
+// in this file.
+//
+// The following statement will instantiate tests from the FooTest test suite
+// each with parameter values "meeny", "miny", and "moe".
+
+INSTANTIATE_TEST_SUITE_P(InstantiationName,
+ FooTest,
+ Values("meeny", "miny", "moe"));
+
+// To distinguish different instances of the pattern, (yes, you
+// can instantiate it more than once) the first argument to the
+// INSTANTIATE_TEST_SUITE_P macro is a prefix that will be added to the
+// actual test suite name. Remember to pick unique prefixes for different
+// instantiations. The tests from the instantiation above will have
+// these names:
+//
+// * InstantiationName/FooTest.DoesBlah/0 for "meeny"
+// * InstantiationName/FooTest.DoesBlah/1 for "miny"

+// * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
+// * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
+//
+// You can use these names in --gtest_filter.
+//
+// This statement will instantiate all tests from FooTest again, each
+// with parameter values "cat" and "dog":
+
+const char* pets[] = {"cat", "dog"};

+// * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog"
+// * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
+// * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
+//
+// Please note that INSTANTIATE_TEST_SUITE_P will instantiate all tests
+// in the given test suite, whether their definitions come before or
+// AFTER the INSTANTIATE_TEST_SUITE_P statement.
+//
+// Please also note that generator expressions (including parameters to the
+// generators) are evaluated in InitGoogleTest(), after main() has started.
+// This allows the user on one hand, to adjust generator parameters in order
+// to dynamically determine a set of tests to run and on the other hand,
+// give the user a chance to inspect the generated tests with Google Test
+// reflection API before RUN_ALL_TESTS() is executed.
+//
+// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
+// for more examples.
+//
+// In the future, we plan to publish the API for defining new parameter
+// generators. But for now this interface remains part of the internal
+// implementation and is subject to change.
+//
+//
+// A parameterized test fixture must be derived from testing::Test and from
+// testing::WithParamInterface<T>, where T is the type of the parameter
+// values. Inheriting from TestWithParam<T> satisfies that requirement because
+// TestWithParam<T> inherits from both Test and WithParamInterface. In more
+// complicated hierarchies, however, it is occasionally useful to inherit
+// separately from Test and WithParamInterface. For example:
+
+class BaseTest : public ::testing::Test {

+
+// Typed (aka type-driven) tests repeat the same test for types in a

+// typed tests. Here's how you do it:
+
+#if 0
+
+// First, define a fixture class template. It should be parameterized
+// by a type. Remember to derive it from testing::Test.
+template <typename T>
+class FooTest : public testing::Test {
+ public:
+ ...
+ typedef std::list<T> List;
+ static T shared_;
+ T value_;
+};
+
+// Next, associate a list of types with the test suite, which will be
+// repeated for each type in the list. The typedef is necessary for
+// the macro to parse correctly.
+typedef testing::Types<char, int, unsigned int> MyTypes;
+TYPED_TEST_SUITE(FooTest, MyTypes);
+
+// If the type list contains only one type, you can write that type
+// directly without Types<...>:
+// TYPED_TEST_SUITE(FooTest, int);
+
+// Then, use TYPED_TEST() instead of TEST_F() to define as many typed
+// tests for this test suite as you want.
+TYPED_TEST(FooTest, DoesBlah) {
+ // Inside a test, refer to the special name TypeParam to get the type
+ // parameter. Since we are inside a derived class template, C++ requires
+ // us to visit the members of FooTest via 'this'.
+ TypeParam n = this->value_;
+
+ // To visit static members of the fixture, add the TestFixture::
+ // prefix.
+ n += TestFixture::shared_;
+
+ // To refer to typedefs in the fixture, add the "typename
+ // TestFixture::" prefix.
+ typename TestFixture::List values;
+ values.push_back(n);
+ ...
+}
+
+TYPED_TEST(FooTest, HasPropertyA) { ... }
+
+// TYPED_TEST_SUITE takes an optional third argument which allows to specify a
+// class that generates custom test name suffixes based on the type. This should
+// be a class which has a static template function GetName(int index) returning
+// a string for each type. The provided integer index equals the index of the
+// type in the provided type list. In many cases the index can be ignored.
+//
+// For example:
+// class MyTypeNames {
+// public:
+// template <typename T>
+// static std::string GetName(int) {
+// if (std::is_same<T, char>()) return "char";
+// if (std::is_same<T, int>()) return "int";
+// if (std::is_same<T, unsigned int>()) return "unsignedInt";
+// }
+// };
+// TYPED_TEST_SUITE(FooTest, MyTypes, MyTypeNames);
+
+#endif // 0
+
+// Type-parameterized tests are abstract test patterns parameterized
+// by a type. Compared with typed tests, type-parameterized tests
+// allow you to define the test pattern without knowing what the type
+// parameters are. The defined pattern can be instantiated with
+// different types any number of times, in any number of translation
+// units.
+//
+// If you are designing an interface or concept, you can define a
+// suite of type-parameterized tests to verify properties that any
+// valid implementation of the interface/concept should have. Then,
+// each implementation can easily instantiate the test suite to verify
+// that it conforms to the requirements, without having to write
+// similar tests repeatedly. Here's an example:
+
+#if 0
+
+// First, define a fixture class template. It should be parameterized
+// by a type. Remember to derive it from testing::Test.
+template <typename T>
+class FooTest : public testing::Test {
+ ...
+};
+
+// Next, declare that you will define a type-parameterized test suite
+// (the _P suffix is for "parameterized" or "pattern", whichever you
+// prefer):
+TYPED_TEST_SUITE_P(FooTest);
+
+// Then, use TYPED_TEST_P() to define as many type-parameterized tests
+// for this type-parameterized test suite as you want.
+TYPED_TEST_P(FooTest, DoesBlah) {
+ // Inside a test, refer to TypeParam to get the type parameter.
+ TypeParam n = 0;
+ ...
+}
+
+TYPED_TEST_P(FooTest, HasPropertyA) { ... }
+
+// Now the tricky part: you need to register all test patterns before
+// you can instantiate them. The first argument of the macro is the
+// test suite name; the rest are the names of the tests in this test
+// case.
+REGISTER_TYPED_TEST_SUITE_P(FooTest,
+ DoesBlah, HasPropertyA);
+
+// Finally, you are free to instantiate the pattern with the types you
+// want. If you put the above code in a header file, you can #include
+// it in multiple C++ source files and instantiate it multiple times.
+//
+// To distinguish different instances of the pattern, the first
+// argument to the INSTANTIATE_* macro is a prefix that will be added

+# Customization Points
+
+The custom directory is an injection point for custom user configurations.
+
+## Header `gtest.h`
+
+### The following macros can be defined:
+
+* `GTEST_OS_STACK_TRACE_GETTER_` - The name of an implementation of
+ `OsStackTraceGetterInterface`.
+* `GTEST_CUSTOM_TEMPDIR_FUNCTION_` - An override for `testing::TempDir()`. See
+ `testing::TempDir` for semantics and signature.
+
+## Header `gtest-port.h`
+
+The following macros can be defined:
+
+### Flag related macros:
+
+* `GTEST_FLAG(flag_name)`
+* `GTEST_USE_OWN_FLAGFILE_FLAG_` - Define to 0 when the system provides its
+ own flagfile flag parsing.
+* `GTEST_DECLARE_bool_(name)`
+* `GTEST_DECLARE_int32_(name)`
+* `GTEST_DECLARE_string_(name)`
+* `GTEST_DEFINE_bool_(name, default_val, doc)`
+* `GTEST_DEFINE_int32_(name, default_val, doc)`
+* `GTEST_DEFINE_string_(name, default_val, doc)`
+* `GTEST_FLAG_GET(flag_name)`
+* `GTEST_FLAG_SET(flag_name, value)`
+
+### Logging:
+
+* `GTEST_LOG_(severity)`
+* `GTEST_CHECK_(condition)`
+* Functions `LogToStderr()` and `FlushInfoLog()` have to be provided too.
+
+### Threading:
+
+* `GTEST_HAS_NOTIFICATION_` - Enabled if Notification is already provided.
+* `GTEST_HAS_MUTEX_AND_THREAD_LOCAL_` - Enabled if `Mutex` and `ThreadLocal`
+ are already provided. Must also provide `GTEST_DECLARE_STATIC_MUTEX_(mutex)`
+ and `GTEST_DEFINE_STATIC_MUTEX_(mutex)`
+* `GTEST_EXCLUSIVE_LOCK_REQUIRED_(locks)`
+* `GTEST_LOCK_EXCLUDED_(locks)`
+
+### Underlying library support features
+
+* `GTEST_HAS_CXXABI_H_`
+
+### Exporting API symbols:
+
+* `GTEST_API_` - Specifier for exported symbols.
+
+## Header `gtest-printers.h`
+
+* See documentation at `gtest/gtest-printers.h` for details on how to define a
+ custom printer.

+// -----------------------------
+//
+// Google Test can be used in many different environments. Macros in
+// this section tell Google Test what kind of environment it is being
+// used in, such that Google Test can provide environment-specific
+// features and implementations.
+//
+// Google Test tries to automatically detect the properties of its
+// environment, so users usually don't need to worry about these
+// macros. However, the automatic detection is not perfect.
+// Sometimes it's necessary for a user to define some of the following
+// macros in the build script to override Google Test's decisions.
+//
+// If the user doesn't define a macro in the list, Google Test will
+// provide a default definition. After this header is #included, all
+// macros in this list will be defined to either 1 or 0.
+//
+// Notes to maintainers:
+// - Each macro here is a user-tweakable knob; do not grow the list
+// lightly.
+// - Use #if to key off these macros. Don't use #ifdef or "#if
+// defined(...)", which will not work as these macros are ALWAYS
+// defined.
+//
+// GTEST_HAS_CLONE - Define it to 1/0 to indicate that clone(2)
+// is/isn't available.
+// GTEST_HAS_EXCEPTIONS - Define it to 1/0 to indicate that exceptions
+// are enabled.

+// Platform-indicating macros
+// --------------------------
+//
+// Macros indicating the platform on which Google Test is being used
+// (a macro is defined to 1 if compiled on the given platform;
+// otherwise UNDEFINED -- it's never defined to 0.). Google Test
+// defines these macros automatically. Code outside Google Test MUST
+// NOT define them.
+//
+// GTEST_OS_AIX - IBM AIX
+// GTEST_OS_CYGWIN - Cygwin
+// GTEST_OS_DRAGONFLY - DragonFlyBSD
+// GTEST_OS_FREEBSD - FreeBSD
+// GTEST_OS_FUCHSIA - Fuchsia

+// don't have access to other platforms, support for them may be less
+// stable. If you notice any problems on your platform, please notify
+// googletestframework@googlegroups.com (patches for fixing them are
+// even more welcome!).
+//
+// It is possible that none of the GTEST_OS_* macros are defined.
+
+// Feature-indicating macros
+// -------------------------
+//
+// Macros indicating which Google Test features are available (a macro
+// is defined to 1 if the corresponding feature is supported;
+// otherwise UNDEFINED -- it's never defined to 0.). Google Test
+// defines these macros automatically. Code outside Google Test MUST
+// NOT define them.
+//
+// These macros are public so that portable tests can be written.
+// Such tests typically surround code using a feature with an #if
+// which controls that code. For example:
+//
+// #if GTEST_HAS_DEATH_TEST
+// EXPECT_DEATH(DoSomethingDeadly());
+// #endif
+//
+// GTEST_HAS_DEATH_TEST - death tests
+// GTEST_HAS_TYPED_TEST - typed tests
+// GTEST_HAS_TYPED_TEST_P - type-parameterized tests
+// GTEST_IS_THREADSAFE - Google Test is thread-safe.
+// GTEST_USES_POSIX_RE - enhanced POSIX regex is used. Do not confuse with
+// GTEST_HAS_POSIX_RE (see above) which users can
+// define themselves.
+// GTEST_USES_SIMPLE_RE - our own simple regex is used;
+// the above RE\b(s) are mutually exclusive.
+
+// Misc public macros
+// ------------------
+//
+// GTEST_FLAG(flag_name) - references the variable corresponding to
+// the given Google Test flag.
+
+// Internal utilities
+// ------------------
+//
+// The following macros and utilities are for Google Test's INTERNAL
+// use only. Code outside Google Test MUST NOT USE THEM DIRECTLY.
+//
+// Macros for basic C++ coding:
+// GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
+// GTEST_ATTRIBUTE_UNUSED_ - declares that a class' instances or a
+// variable don't have to be used.
+// GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=.
+// GTEST_DISALLOW_MOVE_AND_ASSIGN_ - disables move ctor and operator=.
+// GTEST_MUST_USE_RESULT_ - declares that a function's result must be used.
+// GTEST_INTENTIONAL_CONST_COND_PUSH_ - start code section where MSVC C4127 is
+// suppressed (constant conditional).
+// GTEST_INTENTIONAL_CONST_COND_POP_ - finish code section where MSVC C4127
+// is suppressed.
+// GTEST_INTERNAL_HAS_ANY - for enabling UniversalPrinter<std::any> or
+// UniversalPrinter<absl::any> specializations.
+// GTEST_INTERNAL_HAS_OPTIONAL - for enabling UniversalPrinter<std::optional>
+// or
+// UniversalPrinter<absl::optional>
+// specializations.
+// GTEST_INTERNAL_HAS_STRING_VIEW - for enabling Matcher<std::string_view> or
+// Matcher<absl::string_view>
+// specializations.
+// GTEST_INTERNAL_HAS_VARIANT - for enabling UniversalPrinter<std::variant> or
+// UniversalPrinter<absl::variant>
+// specializations.
+//
+// Synchronization:
+// Mutex, MutexLock, ThreadLocal, GetThreadCount()
+// - synchronization primitives.
+//
+// Regular expressions:
+// RE - a simple regular expression class using the POSIX
+// Extended Regular Expression syntax on UNIX-like platforms
+// or a reduced regular exception syntax on other
+// platforms, including Windows.
+// Logging:
+// GTEST_LOG_() - logs messages at the specified severity level.
+// LogToStderr() - directs all log messages to stderr.
+// FlushInfoLog() - flushes informational log messages.
+//
+// Stdout and stderr capturing:
+// CaptureStdout() - starts capturing stdout.
+// GetCapturedStdout() - stops capturing stdout and returns the captured
+// string.
+// CaptureStderr() - starts capturing stderr.
+// GetCapturedStderr() - stops capturing stderr and returns the captured
+// string.
+//
+// Integer types:
+// TypeWithSize - maps an integer to a int type.
+// TimeInMillis - integers of known sizes.
+// BiggestInt - the biggest signed integer type.
+//
+// Command-line utilities:
+// GTEST_DECLARE_*() - declares a flag.
+// GTEST_DEFINE_*() - defines a flag.
+// GetInjectableArgvs() - returns the command line as a vector of strings.
+//
+// Environment variable utilities:
+// GetEnv() - gets the value of an environment variable.
+// BoolFromGTestEnv() - parses a bool environment variable.
+// Int32FromGTestEnv() - parses an int32_t environment variable.
+// StringFromGTestEnv() - parses a string environment variable.
+//
+// Deprecation warnings:
+// GTEST_INTERNAL_DEPRECATED(message) - attribute marking a function as
+// deprecated; calling a marked function
+// should generate a compiler warning

+// A sample program demonstrating using Google C++ testing framework.
+
+// This sample shows how to write a simple unit test for a function,
+// using Google C++ testing framework.
+//
+// Writing a unit test using Google C++ testing framework is easy as 1-2-3:
+
+
+// Step 1. Include necessary header files such that the stuff your
+// test logic needs is declared.
+//
+// Don't forget gtest.h, which declares the testing framework.
+
+#include <limits.h>
+#include "sample1.h"
+#include "gtest/gtest.h"
+namespace {
+
+// Step 2. Use the TEST macro to define your tests.
+//
+// TEST has two parameters: the test case name and the test name.
+// After using the macro, you should define your test logic between a
+// pair of braces. You can use a bunch of macros to indicate the
+// success or failure of a test. EXPECT_TRUE and EXPECT_EQ are
+// examples of such macros. For a complete list, see gtest.h.
+//
+// <TechnicalDetails>
+//
+// In Google Test, tests are grouped into test cases. This is how we
+// keep test code organized. You should put logically related tests
+// into the same test case.
+//
+// The test case name and the test name should both be valid C++
+// identifiers. And you should not use underscore (_) in the names.
+//
+// Google Test guarantees that each test you define is run exactly
+// once, but it makes no guarantee on the order the tests are
+// executed. Therefore, you should write your tests in such a way
+// that their results don't depend on their order.
+//
+// </TechnicalDetails>
+
+
+// Tests Factorial().
+
+// Tests factorial of negative numbers.
+TEST(FactorialTest, Negative) {
+ // This test is named "Negative", and belongs to the "FactorialTest"
+ // test case.
+ EXPECT_EQ(1, Factorial(-5));
+ EXPECT_EQ(1, Factorial(-1));
+ EXPECT_GT(Factorial(-10), 0);
+
+ // <TechnicalDetails>
+ //
+ // EXPECT_EQ(expected, actual) is the same as
+ //
+ // EXPECT_TRUE((expected) == (actual))
+ //
+ // except that it will print both the expected value and the actual
+ // value when the assertion fails. This is very helpful for
+ // debugging. Therefore in this case EXPECT_EQ is preferred.
+ //
+ // On the other hand, EXPECT_TRUE accepts any Boolean expression,
+ // and is thus more general.
+ //
+ // </TechnicalDetails>
+}
+
+// Tests factorial of 0.
+TEST(FactorialTest, Zero) {
+ EXPECT_EQ(1, Factorial(0));
+}
+
+// Tests factorial of positive numbers.

+
+// Tests negative input.

+ // This test belongs to the IsPrimeTest test case.
+
+ EXPECT_FALSE(IsPrime(-1));
+ EXPECT_FALSE(IsPrime(-2));
+ EXPECT_FALSE(IsPrime(INT_MIN));
+}
+
+// Tests some trivial cases.
+TEST(IsPrimeTest, Trivial) {
+ EXPECT_FALSE(IsPrime(0));

+ EXPECT_FALSE(IsPrime(4));
+ EXPECT_TRUE(IsPrime(5));
+ EXPECT_FALSE(IsPrime(6));
+ EXPECT_TRUE(IsPrime(23));
+}
+} // namespace
+
+// Step 3. Call RUN_ALL_TESTS() in main().
+//
+// We do this by linking in src/gtest_main.cc file, which consists of
+// a main() function which calls RUN_ALL_TESTS() for us.
+//
+// This runs all the tests you've defined, prints the result, and
+// returns 0 if successful, or 1 otherwise.
+//
+// Did you notice that we didn't register the tests? The
+// RUN_ALL_TESTS() macro magically knows about all the tests we
+// defined. Isn't this convenient?

+//
+// A test fixture is a place to hold objects and functions shared by
+// all tests in a test case. Using a test fixture avoids duplicating
+// the test code necessary to initialize and cleanup those common
+// objects for each test. It is also useful for defining sub-routines
+// that your tests need to invoke a lot.
+//
+// <TechnicalDetails>
+//
+// The tests share the test fixture in the sense of code sharing, not
+// data sharing. Each test is given its own fresh copy of the
+// fixture. You cannot expect the data modified by one test to be
+// passed on to another test, which is a bad idea.
+//
+// The reason for this design is that tests should be independent and
+// repeatable. In particular, a test should not fail as the result of
+// another test's failure. If one test depends on info produced by
+// another test, then the two tests should really be one big test.
+//
+// The macros for indicating the success/failure of a test
+// (EXPECT_TRUE, FAIL, etc) need to know what the current test is
+// (when Google Test prints the test result, it tells you which test
+// each failure belongs to). Technically, these macros invoke a
+// member function of the Test class. Therefore, you cannot use them
+// in a global function. That's why you should put test sub-routines
+// in a test fixture.

+// cases by deriving sub-fixtures from it.
+//
+// When you define a test fixture, you specify the name of the test
+// case that will use this fixture. Therefore, a test fixture can
+// be used by only one test case.
+//
+// Sometimes, more than one test cases may want to use the same or
+// slightly different test fixtures. For example, you may want to
+// make sure that all tests for a GUI library don't leak important
+// system resources like fonts and brushes. In Google Test, you do
+// this by putting the shared logic in a super (as in "super class")
+// test fixture, and then have each test case use a fixture derived
+// from this super fixture.

+// 2. The parent starts the child and provides it with the information
+// necessary to acquire the handle to the write end of the pipe.
+// 3. The child acquires the write end of the pipe and signals the parent
+// using a Windows event.
+// 4. Now the parent can release the write end of the pipe on its side. If
+// this is done before step 3, the object's reference count goes down to
+// 0 and it is destroyed, preventing the child from acquiring it. The
+// parent now has to release it, or read operations on the read end of
+// the pipe will not return when the child terminates.
+// 5. The parent reads child's output through the pipe (outcome code and
+// any possible error messages) from the pipe, and its stderr and then
+// determines whether to fail the test.

+// Note: to distinguish Win32 API calls from the local method and function

+"""Unit test for Google Test fail_fast.

+A user can specify if a Google Test program should continue test execution
+after a test failure via the GTEST_FAIL_FAST environment variable or the

+by Bazel fail fast environment variable TESTBRIDGE_TEST_RUNNER_FAIL_FAST.

+This script tests such functionality by invoking googletest-failfast-unittest_
+(a program written with Google Test) with different environments and command
