+
+The constructor returns a new C<TAP::Formatter::Console> object. If
+a L<TAP::Harness> is created with no C<formatter> a
+C<TAP::Formatter::Console> is automatically created. If any of the
+following options were given to TAP::Harness->new they well be passed to
+this constructor which accepts an optional hashref whose allowed keys are:
+
+=over 4
+
+=item * C<verbosity>
+
+Set the verbosity level.
+
+=item * C<verbose>
+
+Printing individual test results to STDOUT.
+
+=item * C<timer>
+
+Append run time for each test to output. Uses L<Time::HiRes> if available.
+
+=item * C<failures>
+
+Show test failures (this is a no-op if C<verbose> is selected).
+
+=item * C<comments>
+
+Show test comments (this is a no-op if C<verbose> is selected).
+
+=item * C<quiet>
+
+Suppressing some test output (mostly failures while tests are running).
+
+=item * C<really_quiet>
+
+Suppressing everything but the tests summary.
+
+=item * C<silent>
+
+Suppressing all output.
+
+=item * C<errors>
+
+If parse errors are found in the TAP output, a note of this will be made
+in the summary report. To see all of the parse errors, set this argument to
+true:
+
+ errors => 1
+
+=item * C<directives>
+
+If set to a true value, only test results with directives will be displayed.
+This overrides other settings such as C<verbose>, C<failures>, or C<comments>.
+
+=item * C<stdout>
+
+A filehandle for catching standard output.
+
+=item * C<color>
+
+If defined specifies whether color output is desired. If C<color> is not
+defined it will default to color output if color support is available on
+the current platform and output is not being redirected.
+
+=item * C<jobs>
+
+The number of concurrent jobs this formatter will handle.
+
+=item * C<show_count>
+
+Boolean value. If false, disables the C<X/Y> test count which shows up while
+tests are running.
+
+=back
+
+Any keys for which the value is C<undef> will be ignored.
+
+=cut
+
+# new supplied by TAP::Base
+

+
+Called by Test::Harness before any test output is generated.

+being supplied to Test::Harness by an iterator.

+
+Called to create a new test session. A test session looks like this:

+
+ $harness->summary( $aggregate );
+

+argument is an aggregate to summarise. An optional second argument may
+be set to a true value to indicate that the summary is being output as a
+result of an interrupted test run.

+
+Note that this harness is I<experimental>. You may not like the colors I've

+
+This test harness is the same as L<TAP::Harness>, but test results are output
+in color. Passing tests are printed in green. Failing tests are in red.
+Skipped tests are blue on a white background and TODO tests are printed in

+=head1 METHODS
+
+=head2 Class Methods
+
+=head3 C<new>
+
+ my %args = (
+ verbosity => 1,
+ lib => [ 'lib', 'blib/lib', 'blib/arch' ],
+ )
+ my $harness = TAP::Harness->new( \%args );
+
+The constructor returns a new C<TAP::Harness> object. It accepts an
+optional hashref whose allowed keys are:
+
+=over 4
+
+=item * C<verbosity>
+
+Set the verbosity level:
+
+ 1 verbose Print individual test results to STDOUT.
+ 0 normal
+ -1 quiet Suppress some test output (mostly failures
+ while tests are running).
+ -2 really quiet Suppress everything but the tests summary.
+ -3 silent Suppress everything.
+
+=item * C<timer>
+
+Append run time for each test to output. Uses L<Time::HiRes> if
+available.
+
+=item * C<failures>
+
+Show test failures (this is a no-op if C<verbose> is selected).
+
+=item * C<comments>
+
+Show test comments (this is a no-op if C<verbose> is selected).
+
+=item * C<show_count>
+
+Update the running test count during testing.
+
+=item * C<normalize>
+
+Set to a true value to normalize the TAP that is emitted in verbose modes.
+
+=item * C<lib>
+
+Accepts a scalar value or array ref of scalar values indicating which
+paths to allowed libraries should be included if Perl tests are
+executed. Naturally, this only makes sense in the context of tests
+written in Perl.
+
+=item * C<switches>
+
+Accepts a scalar value or array ref of scalar values indicating which
+switches should be included if Perl tests are executed. Naturally, this
+only makes sense in the context of tests written in Perl.
+
+=item * C<test_args>
+
+A reference to an C<@INC> style array of arguments to be passed to each
+test program.
+
+ test_args => ['foo', 'bar'],
+
+if you want to pass different arguments to each test then you should
+pass a hash of arrays, keyed by the alias for each test:
+
+ test_args => {
+ my_test => ['foo', 'bar'],
+ other_test => ['baz'],
+ }
+
+=item * C<color>
+
+Attempt to produce color output.
+
+=item * C<exec>
+
+Typically, Perl tests are run through this. However, anything which
+spits out TAP is fine. You can use this argument to specify the name of
+the program (and optional switches) to run your tests with:
+
+ exec => ['/usr/bin/ruby', '-w']
+
+You can also pass a subroutine reference in order to determine and
+return the proper program to run based on a given test script. The
+subroutine reference should expect the TAP::Harness object itself as the
+first argument, and the file name as the second argument. It should
+return an array reference containing the command to be run and including
+the test file name. It can also simply return C<undef>, in which case
+TAP::Harness will fall back on executing the test script in Perl:
+
+ exec => sub {
+ my ( $harness, $test_file ) = @_;
+
+ # Let Perl tests run.
+ return undef if $test_file =~ /[.]t$/;
+ return [ qw( /usr/bin/ruby -w ), $test_file ]
+ if $test_file =~ /[.]rb$/;
+ }
+
+If the subroutine returns a scalar with a newline or a filehandle, it
+will be interpreted as raw TAP or as a TAP stream, respectively.
+
+=item * C<merge>
+
+If C<merge> is true the harness will create parsers that merge STDOUT
+and STDERR together for any processes they start.
+
+=item * C<sources>
+
+I<NEW to 3.18>.
+
+If set, C<sources> must be a hashref containing the names of the
+L<TAP::Parser::SourceHandler>s to load and/or configure. The values are a
+hash of configuration that will be accessible to the source handlers via
+L<TAP::Parser::Source/config_for>.
+
+For example:
+
+ sources => {
+ Perl => { exec => '/path/to/custom/perl' },
+ File => { extensions => [ '.tap', '.txt' ] },
+ MyCustom => { some => 'config' },
+ }
+
+The C<sources> parameter affects how C<source>, C<tap> and C<exec> parameters
+are handled.
+
+For more details, see the C<sources> parameter in L<TAP::Parser/new>,
+L<TAP::Parser::Source>, and L<TAP::Parser::IteratorFactory>.
+
+=item * C<aggregator_class>
+
+The name of the class to use to aggregate test results. The default is
+L<TAP::Parser::Aggregator>.
+
+=item * C<version>
+
+I<NEW to 3.22>.
+
+Assume this TAP version for L<TAP::Parser> instead of default TAP
+version 12.
+
+=item * C<formatter_class>
+
+The name of the class to use to format output. The default is
+L<TAP::Formatter::Console>, or L<TAP::Formatter::File> if the output
+isn't a TTY.
+
+=item * C<multiplexer_class>
+
+The name of the class to use to multiplex tests during parallel testing.
+The default is L<TAP::Parser::Multiplexer>.
+
+=item * C<parser_class>
+
+The name of the class to use to parse TAP. The default is
+L<TAP::Parser>.
+
+=item * C<scheduler_class>
+
+The name of the class to use to schedule test execution. The default is
+L<TAP::Parser::Scheduler>.
+
+=item * C<formatter>
+
+If set C<formatter> must be an object that is capable of formatting the
+TAP output. See L<TAP::Formatter::Console> for an example.
+
+=item * C<errors>
+
+If parse errors are found in the TAP output, a note of this will be
+made in the summary report. To see all of the parse errors, set this
+argument to true:
+
+ errors => 1
+
+=item * C<directives>
+
+If set to a true value, only test results with directives will be
+displayed. This overrides other settings such as C<verbose> or
+C<failures>.
+
+=item * C<ignore_exit>
+
+If set to a true value instruct C<TAP::Parser> to ignore exit and wait
+status from test scripts.
+
+=item * C<jobs>
+
+The maximum number of parallel tests to run at any time. Which tests
+can be run in parallel is controlled by C<rules>. The default is to
+run only one test at a time.
+
+=item * C<rules>
+
+A reference to a hash of rules that control which tests may be executed in
+parallel. If no rules are declared and L<CPAN::Meta::YAML> is available,
+C<TAP::Harness> attempts to load rules from a YAML file specified by the
+C<rulesfile> parameter. If no rules file exists, the default is for all
+tests to be eligible to be run in parallel.
+
+Here some simple examples. For the full details of the data structure
+and the related glob-style pattern matching, see
+L<TAP::Parser::Scheduler/"Rules data structure">.
+
+ # Run all tests in sequence, except those starting with "p"
+ $harness->rules({
+ par => 't/p*.t'
+ });
+
+ # Equivalent YAML file
+ ---
+ par: t/p*.t
+
+ # Run all tests in parallel, except those starting with "p"
+ $harness->rules({
+ seq => [
+ { seq => 't/p*.t' },
+ { par => '**' },
+ ],
+ });
+
+ # Equivalent YAML file
+ ---
+ seq:
+ - seq: t/p*.t
+ - par: **
+
+ # Run some startup tests in sequence, then some parallel tests than some
+ # teardown tests in sequence.
+ $harness->rules({
+ seq => [
+ { seq => 't/startup/*.t' },
+ { par => ['t/a/*.t','t/b/*.t','t/c/*.t'], }
+ { seq => 't/shutdown/*.t' },
+ ],
+
+ });
+
+ # Equivalent YAML file
+ ---
+ seq:
+ - seq: t/startup/*.t
+ - par:
+ - t/a/*.t
+ - t/b/*.t
+ - t/c/*.t
+ - seq: t/shutdown/*.t
+
+This is an experimental feature and the interface may change.
+
+=item * C<rulesfiles>
+
+This specifies where to find a YAML file of test scheduling rules. If not
+provided, it looks for a default file to use. It first checks for a file given
+in the C<HARNESS_RULESFILE> environment variable, then it checks for
+F<testrules.yml> and then F<t/testrules.yml>.
+
+=item * C<stdout>
+
+A filehandle for catching standard output.
+
+=item * C<trap>
+
+Attempt to print summary information if run is interrupted by
+SIGINT (Ctrl-C).
+
+=back
+
+Any keys for which the value is C<undef> will be ignored.

+
+=head3 C<runtests>
+
+ $harness->runtests(@tests);
+
+Accepts an array of C<@tests> to be run. This should generally be the
+names of test files, but this is not required. Each element in C<@tests>
+will be passed to C<TAP::Parser::new()> as a C<source>. See
+L<TAP::Parser> for more information.
+
+It is possible to provide aliases that will be displayed in place of the
+test name by supplying the test as a reference to an array containing
+C<< [ $test, $alias ] >>:
+
+ $harness->runtests( [ 't/foo.t', 'Foo Once' ],
+ [ 't/foo.t', 'Foo Twice' ] );
+
+Normally it is an error to attempt to run the same test twice. Aliases
+allow you to overcome this limitation by giving each run of the test a
+unique name.
+
+Tests will be run in the order found.
+
+If the environment variable C<PERL_TEST_HARNESS_DUMP_TAP> is defined it
+should name a directory into which a copy of the raw TAP for each test
+will be written. TAP is written to files named for each test.
+Subdirectories will be created as needed.
+
+Returns a L<TAP::Parser::Aggregator> containing the test results.

+Run the named tests and display a summary of result. Tests will be run

+
+Test results will be added to the supplied L<TAP::Parser::Aggregator>.
+C<aggregate_tests> may be called multiple times to run several sets of
+tests. Multiple C<Test::Harness> instances may be used to pass results
+to a single aggregator so that different parts of a complex test suite
+may be run using different C<TAP::Harness> settings. This is useful, for
+example, in the case where some tests should run in parallel but others

+

+
+In the case of a perl test suite, typically I<source names> are simply the file
+names of the test scripts to run.
+
+When you supply a separate display name it becomes possible to run a
+test more than once; the display name is effectively the alias by which
+the test is known inside the harness. The harness doesn't care if it
+runs the same test more than once when each invocation uses a
+different name.

+=head1 CONFIGURING
+
+C<TAP::Harness> is designed to be easy to configure.
+
+=head2 Plugins
+
+C<TAP::Parser> plugins let you change the way TAP is I<input> to and I<output>
+from the parser.
+
+L<TAP::Parser::SourceHandler>s handle TAP I<input>. You can configure them
+and load custom handlers using the C<sources> parameter to L</new>.
+
+L<TAP::Formatter>s handle TAP I<output>. You can load custom formatters by
+using the C<formatter_class> parameter to L</new>. To configure a formatter,
+you currently need to instantiate it outside of L<TAP::Harness> and pass it in
+with the C<formatter> parameter to L</new>. This I<may> be addressed by adding
+a I<formatters> parameter to L</new> in the future.
+
+=head2 C<Module::Build>
+
+L<Module::Build> version C<0.30> supports C<TAP::Harness>.
+
+To load C<TAP::Harness> plugins, you'll need to use the C<tap_harness_args>
+parameter to C<new>, typically from your C<Build.PL>. For example:
+
+ Module::Build->new(
+ module_name => 'MyApp',
+ test_file_exts => [qw(.t .tap .txt)],

+

+

+
+To do this, you can either extend an existing L<TAP::Parser::SourceHandler>,
+or write your own. It's a pretty simple API, and they can be loaded and

+
+=item Customize how TAP results are output from the parser
+
+To do this, you can either extend an existing L<TAP::Formatter>, or write your
+own. Writing formatters are a bit more involved than writing a

+Custom formatters can be loaded configured using the C<formatter_class>

+=head1 SUBCLASSING
+
+If you can't configure C<TAP::Harness> to do exactly what you want, and writing

+C<runtests> methods. Then you can use the C<prove> utility like so:
+
+ prove --harness My::Test::Harness
+
+Note that while C<prove> accepts a list of tests (or things to be

+to read over this code carefully to see how all of them are being used.

+=head1 NAME
+
+Test::Harness::Beyond - Beyond make test
+
+=head1 Beyond make test
+
+Test::Harness is responsible for running test scripts, analysing
+their output and reporting success or failure. When I type
+F<make test> (or F<./Build test>) for a module, Test::Harness is usually
+used to run the tests (not all modules use Test::Harness but the
+majority do).
+
+To start exploring some of the features of Test::Harness I need to
+switch from F<make test> to the F<prove> command (which ships with
+Test::Harness). For the following examples I'll also need a recent
+version of Test::Harness installed; 3.14 is current as I write.
+
+For the examples I'm going to assume that we're working with a
+'normal' Perl module distribution. Specifically I'll assume that
+typing F<make> or F<./Build> causes the built, ready-to-install module
+code to be available below ./blib/lib and ./blib/arch and that
+there's a directory called 't' that contains our tests. Test::Harness
+isn't hardwired to that configuration but it saves me from explaining
+which files live where for each example.
+
+Back to F<prove>; like F<make test> it runs a test suite - but it
+provides far more control over which tests are executed, in what
+order and how their results are reported. Typically F<make test>
+runs all the test scripts below the 't' directory. To do the same
+thing with prove I type:
+
+ prove -rb t
+
+The switches here are -r to recurse into any directories below 't'
+and -b which adds ./blib/lib and ./blib/arch to Perl's include path
+so that the tests can find the code they will be testing. If I'm
+testing a module of which an earlier version is already installed
+I need to be careful about the include path to make sure I'm not
+running my tests against the installed version rather than the new
+one that I'm working on.
+
+Unlike F<make test>, typing F<prove> doesn't automatically rebuild
+my module. If I forget to make before prove I will be testing against
+older versions of those files - which inevitably leads to confusion.
+I either get into the habit of typing
+
+ make && prove -rb t
+
+or - if I have no XS code that needs to be built I use the modules
+below F<lib> instead
+
+ prove -Ilib -r t
+
+So far I've shown you nothing that F<make test> doesn't do. Let's
+fix that.
+
+=head2 Saved State
+
+If I have failing tests in a test suite that consists of more than
+a handful of scripts and takes more than a few seconds to run it
+rapidly becomes tedious to run the whole test suite repeatedly as
+I track down the problems.
+
+I can tell prove just to run the tests that are failing like this:
+
+ prove -b t/this_fails.t t/so_does_this.t
+
+That speeds things up but I have to make a note of which tests are
+failing and make sure that I run those tests. Instead I can use
+prove's --state switch and have it keep track of failing tests for
+me. First I do a complete run of the test suite and tell prove to
+save the results:
+
+ prove -rb --state=save t
+
+That stores a machine readable summary of the test run in a file
+called '.prove' in the current directory. If I have failures I can
+then run just the failing scripts like this:
+
+ prove -b --state=failed
+
+I can also tell prove to save the results again so that it updates
+its idea of which tests failed:
+
+ prove -b --state=failed,save
+
+As soon as one of my failing tests passes it will be removed from
+the list of failed tests. Eventually I fix them all and prove can
+find no failing tests to run:
+
+ Files=0, Tests=0, 0 wallclock secs ( 0.00 usr + 0.00 sys = 0.00 CPU)
+ Result: NOTESTS
+
+As I work on a particular part of my module it's most likely that
+the tests that cover that code will fail. I'd like to run the whole
+test suite but have it prioritize these 'hot' tests. I can tell
+prove to do this:
+
+ prove -rb --state=hot,save t
+
+All the tests will run but those that failed most recently will be
+run first. If no tests have failed since I started saving state all
+tests will run in their normal order. This combines full test
+coverage with early notification of failures.
+
+The --state switch supports a number of options; for example to run
+failed tests first followed by all remaining tests ordered by the
+timestamps of the test scripts - and save the results - I can use
+
+ prove -rb --state=failed,new,save t
+
+See the prove documentation (type prove --man) for the full list
+of state options.
+
+When I tell prove to save state it writes a file called '.prove'
+('_prove' on Windows) in the current directory. It's a YAML document
+so it's quite easy to write tools of your own that work on the saved
+test state - but the format isn't officially documented so it might
+change without (much) warning in the future.
+
+=head2 Parallel Testing
+
+If my tests take too long to run I may be able to speed them up by
+running multiple test scripts in parallel. This is particularly
+effective if the tests are I/O bound or if I have multiple CPU
+cores. I tell prove to run my tests in parallel like this:
+
+ prove -rb -j 9 t
+
+The -j switch enables parallel testing; the number that follows it
+is the maximum number of tests to run in parallel. Sometimes tests
+that pass when run sequentially will fail when run in parallel. For
+example if two different test scripts use the same temporary file
+or attempt to listen on the same socket I'll have problems running
+them in parallel. If I see unexpected failures I need to check my
+tests to work out which of them are trampling on the same resource
+and rename temporary files or add locks as appropriate.
+
+To get the most performance benefit I want to have the test scripts
+that take the longest to run start first - otherwise I'll be waiting
+for the one test that takes nearly a minute to complete after all
+the others are done. I can use the --state switch to run the tests
+in slowest to fastest order:
+
+ prove -rb -j 9 --state=slow,save t
+
+=head2 Non-Perl Tests
+
+The Test Anything Protocol (http://testanything.org/) isn't just
+for Perl. Just about any language can be used to write tests that
+output TAP. There are TAP based testing libraries for C, C++, PHP,
+Python and many others. If I can't find a TAP library for my language
+of choice it's easy to generate valid TAP. It looks like this:
+
+ 1..3
+ ok 1 - init OK
+ ok 2 - opened file
+ not ok 3 - appended to file
+
+The first line is the plan - it specifies the number of tests I'm
+going to run so that it's easy to check that the test script didn't
+exit before running all the expected tests. The following lines are
+the test results - 'ok' for pass, 'not ok' for fail. Each test has
+a number and, optionally, a description. And that's it. Any language
+that can produce output like that on STDOUT can be used to write
+tests.
+
+Recently I've been rekindling a two-decades-old interest in Forth.
+Evidently I have a masochistic streak that even Perl can't satisfy.
+I want to write tests in Forth and run them using prove (you can
+find my gforth TAP experiments at
+https://svn.hexten.net/andy/Forth/Testing/). I can use the --exec
+switch to tell prove to run the tests using gforth like this:
+
+ prove -r --exec gforth t
+
+Alternately, if the language used to write my tests allows a shebang
+line I can use that to specify the interpreter. Here's a test written
+in PHP:
+
+ #!/usr/bin/php
+ <?php
+ print "1..2\n";
+ print "ok 1\n";
+ print "not ok 2\n";
+ ?>
+
+If I save that as t/phptest.t the shebang line will ensure that it
+runs correctly along with all my other tests.
+
+=head2 Mixing it up
+
+Subtle interdependencies between test programs can mask problems -
+for example an earlier test may neglect to remove a temporary file
+that affects the behaviour of a later test. To find this kind of
+problem I use the --shuffle and --reverse options to run my tests
+in random or reversed order.
+
+=head2 Rolling My Own
+
+If I need a feature that prove doesn't provide I can easily write my own.
+
+Typically you'll want to change how TAP gets I<input> into and I<output>
+from the parser. L<App::Prove> supports arbitrary plugins, and L<TAP::Harness>
+supports custom I<formatters> and I<source handlers> that you can load using
+either L<prove> or L<Module::Build>; there are many examples to base mine on.
+For more details see L<App::Prove>, L<TAP::Parser::SourceHandler>, and
+L<TAP::Formatter::Base>.
+
+If writing a plugin is not enough, you can write your own test harness; one of
+the motives for the 3.00 rewrite of Test::Harness was to make it easier to
+subclass and extend.
+
+The Test::Harness module is a compatibility wrapper around TAP::Harness.
+For new applications I should use TAP::Harness directly. As we'll
+see, prove uses TAP::Harness.
+
+When I run prove it processes its arguments, figures out which test
+scripts to run and then passes control to TAP::Harness to run the
+tests, parse, analyse and present the results. By subclassing
+TAP::Harness I can customise many aspects of the test run.
+
+I want to log my test results in a database so I can track them
+over time. To do this I override the summary method in TAP::Harness.
+I start with a simple prototype that dumps the results as a YAML
+document:
+
+ package My::TAP::Harness;
+
+ use base 'TAP::Harness';
+ use YAML;
+
+ sub summary {
+ my ( $self, $aggregate ) = @_;
+ print Dump( $aggregate );
+ $self->SUPER::summary( $aggregate );
+ }
+
+ 1;
+
+I need to tell prove to use my My::TAP::Harness. If My::TAP::Harness
+is on Perl's @INC include path I can
+
+ prove --harness=My::TAP::Harness -rb t
+
+If I don't have My::TAP::Harness installed on @INC I need to provide
+the correct path to perl when I run prove:
+
+ perl -Ilib `which prove` --harness=My::TAP::Harness -rb t
+
+I can incorporate these options into my own version of prove. It's
+pretty simple. Most of the work of prove is handled by App::Prove.
+The important code in prove is just:
+
+ use App::Prove;
+
+ my $app = App::Prove->new;
+ $app->process_args(@ARGV);
+ exit( $app->run ? 0 : 1 );
+
+If I write a subclass of App::Prove I can customise any aspect of
+the test runner while inheriting all of prove's behaviour. Here's
+myprove:
+
+ #!/usr/bin/env perl use lib qw( lib ); # Add ./lib to @INC
+ use App::Prove;
+
+ my $app = App::Prove->new;
+
+ # Use custom TAP::Harness subclass
+ $app->harness( 'My::TAP::Harness' );
+
+ $app->process_args( @ARGV ); exit( $app->run ? 0 : 1 );
+
+Now I can run my tests like this
+
+ ./myprove -rb t
+
+=head2 Deeper Customisation
+
+Now that I know how to subclass and replace TAP::Harness I can
+replace any other part of the harness. To do that I need to know
+which classes are responsible for which functionality. Here's a
+brief guided tour; the default class for each component is shown
+in parentheses. Normally any replacements I write will be subclasses
+of these default classes.
+
+When I run my tests TAP::Harness creates a scheduler
+(TAP::Parser::Scheduler) to work out the running order for the
+tests, an aggregator (TAP::Parser::Aggregator) to collect and analyse
+the test results and a formatter (TAP::Formatter::Console) to display
+those results.
+
+If I'm running my tests in parallel there may also be a multiplexer
+(TAP::Parser::Multiplexer) - the component that allows multiple
+tests to run simultaneously.
+
+Once it has created those helpers TAP::Harness starts running the
+tests. For each test it creates a new parser (TAP::Parser) which
+is responsible for running the test script and parsing its output.
+
+To replace any of these components I call one of these harness
+methods with the name of the replacement class:
+
+ aggregator_class
+ formatter_class
+ multiplexer_class
+ parser_class
+ scheduler_class
+
+For example, to replace the aggregator I would
+
+ $harness->aggregator_class( 'My::Aggregator' );
+
+Alternately I can supply the names of my substitute classes to the
+TAP::Harness constructor:
+
+ my $harness = TAP::Harness->new(
+ { aggregator_class => 'My::Aggregator' }
+ );
+
+If I need to reach even deeper into the internals of the harness I
+can replace the classes that TAP::Parser uses to execute test scripts
+and tokenise their output. Before running a test script TAP::Parser
+creates a grammar (TAP::Parser::Grammar) to decode the raw TAP into
+tokens, a result factory (TAP::Parser::ResultFactory) to turn the
+decoded TAP results into objects and, depending on whether it's
+running a test script or reading TAP from a file, scalar or array
+a source or an iterator (TAP::Parser::IteratorFactory).
+
+Each of these objects may be replaced by calling one of these parser
+methods:
+
+ source_class
+ perl_source_class
+ grammar_class
+ iterator_factory_class
+ result_factory_class
+
+=head2 Callbacks
+
+As an alternative to subclassing the components I need to change I
+can attach callbacks to the default classes. TAP::Harness exposes
+these callbacks:
+
+ parser_args Tweak the parameters used to create the parser
+ made_parser Just made a new parser
+ before_runtests About to run tests
+ after_runtests Have run all tests
+ after_test Have run an individual test script
+
+TAP::Parser also supports callbacks; bailout, comment, plan, test,
+unknown, version and yaml are called for the corresponding TAP
+result types, ALL is called for all results, ELSE is called for all
+results for which a named callback is not installed and EOF is
+called once at the end of each TAP stream.
+
+To install a callback I pass the name of the callback and a subroutine
+reference to TAP::Harness or TAP::Parser's callback method:
+
+ $harness->callback( after_test => sub {
+ my ( $script, $desc, $parser ) = @_;
+ } );
+
+I can also pass callbacks to the constructor:
+
+ my $harness = TAP::Harness->new({
+ callbacks => {
+ after_test => sub {
+ my ( $script, $desc, $parser ) = @_;
+ # Do something interesting here
+ }
+ }
+ });
+
+When it comes to altering the behaviour of the test harness there's
+more than one way to do it. Which way is best depends on my
+requirements. In general if I only want to observe test execution
+without changing the harness' behaviour (for example to log test
+results to a database) I choose callbacks. If I want to make the
+harness behave differently subclassing gives me more control.
+
+=head2 Parsing TAP
+
+Perhaps I don't need a complete test harness. If I already have a
+TAP test log that I need to parse all I need is TAP::Parser and the
+various classes it depends upon. Here's the code I need to run a
+test and parse its TAP output
+
+ use TAP::Parser;
+
+ my $parser = TAP::Parser->new( { source => 't/simple.t' } );
+ while ( my $result = $parser->next ) {
+ print $result->as_string, "\n";
+ }
+
+Alternately I can pass an open filehandle as source and have the
+parser read from that rather than attempting to run a test script:
+
+ open my $tap, '<', 'tests.tap'
+ or die "Can't read TAP transcript ($!)\n";
+ my $parser = TAP::Parser->new( { source => $tap } );
+ while ( my $result = $parser->next ) {
+ print $result->as_string, "\n";
+ }
+
+This approach is useful if I need to convert my TAP based test
+results into some other representation. See TAP::Convert::TET
+(http://search.cpan.org/dist/TAP-Convert-TET/) for an example of
+this approach.
+

+
+ my $harness = TAP::Harness::Env->create(\%extra_args)
+
+=head1 DESCRIPTION
+
+This module implements the environmental variables that L<Test::Harness> uses with TAP::Harness, and instantiates the appropriate class with the appropriate arguments.
+
+=head1 METHODS
+
+=over 4
+
+=item * create( \%args )
+
+This function reads the environment and generates an appropriate argument hash from it. If given any arguments in C<%extra_args>, these will override the environmental defaults. In accepts C<harness_class> (which defaults to C<TAP::Harness>), and any argument the harness class accepts.
+
+=back
+
+=head1 ENVIRONMENTAL VARIABLES
+
+=over 4
+
+=item C<HARNESS_PERL_SWITCHES>
+
+Setting this adds perl command line switches to each test file run.
+
+For example, C<HARNESS_PERL_SWITCHES=-T> will turn on taint mode.
+C<HARNESS_PERL_SWITCHES=-MDevel::Cover> will run C<Devel::Cover> for
+each test.
+
+=item C<HARNESS_VERBOSE>
+
+If true, C<TAP::Harness> will output the verbose results of running
+its tests.
+
+=item C<HARNESS_SUBCLASS>
+
+Specifies a TAP::Harness subclass to be used in place of TAP::Harness.
+
+=item C<HARNESS_OPTIONS>
+
+Provide additional options to the harness. Currently supported options are:
+
+=over
+
+=item C<< j<n> >>
+
+Run <n> (default 9) parallel jobs.
+
+=item C<< c >>
+
+Try to color output. See L<TAP::Formatter::Base/"new">.
+
+=item C<< a<file.tgz> >>
+
+Will use L<TAP::Harness::Archive> as the harness class, and save the TAP to
+C<file.tgz>
+
+=item C<< fPackage-With-Dashes >>
+
+Set the formatter_class of the harness being run. Since the C<HARNESS_OPTIONS>
+is separated by C<:>, we use C<-> instead.
+
+=back
+
+Multiple options may be separated by colons:
+
+ HARNESS_OPTIONS=j9:c make test
+
+=item C<HARNESS_TIMER>
+
+Setting this to true will make the harness display the number of
+milliseconds each test took. You can also use F<prove>'s C<--timer>
+switch.
+
+=item C<HARNESS_COLOR>
+
+Attempt to produce color output.
+
+=item C<HARNESS_IGNORE_EXIT>
+
+If set to a true value instruct C<TAP::Parser> to ignore exit and wait
+status from test scripts.

+=head1 DESCRIPTION
+
+C<TAP::Parser> is designed to produce a proper parse of TAP output. For
+an example of how to run tests through this module, see the simple
+harnesses C<examples/>.
+
+There's a wiki dedicated to the Test Anything Protocol:
+
+L<http://testanything.org>
+
+It includes the TAP::Parser Cookbook:
+
+L<http://testanything.org/testing-with-tap/perl/tap::parser-cookbook.html>
+
+=head1 METHODS
+
+=head2 Class Methods
+
+=head3 C<new>
+
+ my $parser = TAP::Parser->new(\%args);
+
+Returns a new C<TAP::Parser> object.
+
+The arguments should be a hashref with I<one> of the following keys:
+
+=over 4
+
+=item * C<source>
+
+I<CHANGED in 3.18>
+
+This is the preferred method of passing input to the constructor.
+
+The C<source> is used to create a L<TAP::Parser::Source> that is passed to the
+L</iterator_factory_class> which in turn figures out how to handle the source and
+creates a <TAP::Parser::Iterator> for it. The iterator is used by the parser to
+read in the TAP stream.
+
+To configure the I<IteratorFactory> use the C<sources> parameter below.
+
+Note that C<source>, C<tap> and C<exec> are I<mutually exclusive>.
+
+=item * C<tap>
+
+I<CHANGED in 3.18>
+
+The value should be the complete TAP output.
+
+The I<tap> is used to create a L<TAP::Parser::Source> that is passed to the
+L</iterator_factory_class> which in turn figures out how to handle the source and
+creates a <TAP::Parser::Iterator> for it. The iterator is used by the parser to
+read in the TAP stream.
+
+To configure the I<IteratorFactory> use the C<sources> parameter below.
+
+Note that C<source>, C<tap> and C<exec> are I<mutually exclusive>.
+
+=item * C<exec>
+
+Must be passed an array reference.
+
+The I<exec> array ref is used to create a L<TAP::Parser::Source> that is passed
+to the L</iterator_factory_class> which in turn figures out how to handle the
+source and creates a <TAP::Parser::Iterator> for it. The iterator is used by
+the parser to read in the TAP stream.
+
+By default the L<TAP::Parser::SourceHandler::Executable> class will create a
+L<TAP::Parser::Iterator::Process> object to handle the source. This passes the
+array reference strings as command arguments to L<IPC::Open3::open3|IPC::Open3>:
+
+ exec => [ '/usr/bin/ruby', 't/my_test.rb' ]
+
+If any C<test_args> are given they will be appended to the end of the command
+argument list.
+
+To configure the I<IteratorFactory> use the C<sources> parameter below.
+
+Note that C<source>, C<tap> and C<exec> are I<mutually exclusive>.
+
+=back
+
+The following keys are optional.
+
+=over 4
+
+=item * C<sources>
+
+I<NEW to 3.18>.
+
+If set, C<sources> must be a hashref containing the names of the
+L<TAP::Parser::SourceHandler>s to load and/or configure. The values are a
+hash of configuration that will be accessible to the source handlers via
+L<TAP::Parser::Source/config_for>.
+
+For example:
+
+ sources => {
+ Perl => { exec => '/path/to/custom/perl' },
+ File => { extensions => [ '.tap', '.txt' ] },
+ MyCustom => { some => 'config' },
+ }
+
+This will cause C<TAP::Parser> to pass custom configuration to two of the built-
+in source handlers - L<TAP::Parser::SourceHandler::Perl>,
+L<TAP::Parser::SourceHandler::File> - and attempt to load the C<MyCustom>
+class. See L<TAP::Parser::IteratorFactory/load_handlers> for more detail.
+
+The C<sources> parameter affects how C<source>, C<tap> and C<exec> parameters
+are handled.
+
+See L<TAP::Parser::IteratorFactory>, L<TAP::Parser::SourceHandler> and subclasses for
+more details.
+
+=item * C<callback>
+
+If present, each callback corresponding to a given result type will be called
+with the result as the argument if the C<run> method is used:
+
+ my %callbacks = (
+ test => \&test_callback,
+ plan => \&plan_callback,
+ comment => \&comment_callback,
+ bailout => \&bailout_callback,
+ unknown => \&unknown_callback,
+ );
+
+ my $aggregator = TAP::Parser::Aggregator->new;
+ for my $file ( @test_files ) {
+ my $parser = TAP::Parser->new(
+ {
+ source => $file,
+ callbacks => \%callbacks,
+ }
+ );
+ $parser->run;
+ $aggregator->add( $file, $parser );
+ }
+
+=item * C<switches>
+
+If using a Perl file as a source, optional switches may be passed which will
+be used when invoking the perl executable.
+
+ my $parser = TAP::Parser->new( {
+ source => $test_file,
+ switches => [ '-Ilib' ],
+ } );
+
+=item * C<test_args>
+
+Used in conjunction with the C<source> and C<exec> option to supply a reference
+to an C<@ARGV> style array of arguments to pass to the test program.
+
+=item * C<spool>
+
+If passed a filehandle will write a copy of all parsed TAP to that handle.
+
+=item * C<merge>
+
+If false, STDERR is not captured (though it is 'relayed' to keep it
+somewhat synchronized with STDOUT.)
+
+If true, STDERR and STDOUT are the same filehandle. This may cause
+breakage if STDERR contains anything resembling TAP format, but does
+allow exact synchronization.
+
+Subtleties of this behavior may be platform-dependent and may change in
+the future.
+
+=item * C<grammar_class>
+
+This option was introduced to let you easily customize which I<grammar> class
+the parser should use. It defaults to L<TAP::Parser::Grammar>.
+
+See also L</make_grammar>.
+
+=item * C<result_factory_class>
+
+This option was introduced to let you easily customize which I<result>
+factory class the parser should use. It defaults to
+L<TAP::Parser::ResultFactory>.
+
+See also L</make_result>.
+
+=item * C<iterator_factory_class>
+
+I<CHANGED in 3.18>
+
+This option was introduced to let you easily customize which I<iterator>
+factory class the parser should use. It defaults to
+L<TAP::Parser::IteratorFactory>.

+=head1 INDIVIDUAL RESULTS
+
+If you've read this far in the docs, you've seen this:
+
+ while ( my $result = $parser->next ) {
+ print $result->as_string;
+ }
+
+Each result returned is a L<TAP::Parser::Result> subclass, referred to as
+I<result types>.
+
+=head2 Result types
+
+Basically, you fetch individual results from the TAP. The six types, with
+examples of each, are as follows:
+
+=over 4
+
+=item * Version
+
+ TAP version 12
+
+=item * Plan
+
+ 1..42
+
+=item * Pragma
+
+ pragma +strict
+
+=item * Test
+
+ ok 3 - We should start with some foobar!
+
+=item * Comment
+
+ # Hope we don't use up the foobar.
+
+=item * Bailout
+
+ Bail out! We ran out of foobar!
+
+=item * Unknown
+
+ ... yo, this ain't TAP! ...
+
+=back
+
+Each result fetched is a result object of a different type. There are common
+methods to each result object and different types may have methods unique to
+their type. Sometimes a type method may be overridden in a subclass, but its
+use is guaranteed to be identical.
+
+=head2 Common type methods
+
+=head3 C<type>
+
+Returns the type of result, such as C<comment> or C<test>.
+
+=head3 C<as_string>
+
+Prints a string representation of the token. This might not be the exact
+output, however. Tests will have test numbers added if not present, TODO and
+SKIP directives will be capitalized and, in general, things will be cleaned
+up. If you need the original text for the token, see the C<raw> method.
+
+=head3 C<raw>
+
+Returns the original line of text which was parsed.
+
+=head3 C<is_plan>
+
+Indicates whether or not this is the test plan line.
+
+=head3 C<is_test>
+
+Indicates whether or not this is a test line.
+
+=head3 C<is_comment>
+
+Indicates whether or not this is a comment. Comments will generally only
+appear in the TAP stream if STDERR is merged to STDOUT. See the
+C<merge> option.
+
+=head3 C<is_bailout>
+
+Indicates whether or not this is bailout line.
+
+=head3 C<is_yaml>
+
+Indicates whether or not the current item is a YAML block.
+
+=head3 C<is_unknown>
+
+Indicates whether or not the current line could be parsed.
+
+=head3 C<is_ok>
+
+ if ( $result->is_ok ) { ... }
+
+Reports whether or not a given result has passed. Anything which is B<not> a
+test result returns true. This is merely provided as a convenient shortcut
+which allows you to do this:
+
+ my $parser = TAP::Parser->new( { source => $source } );
+ while ( my $result = $parser->next ) {
+ # only print failing results
+ print $result->as_string unless $result->is_ok;
+ }
+
+=head2 C<plan> methods
+
+ if ( $result->is_plan ) { ... }
+
+If the above evaluates as true, the following methods will be available on the
+C<$result> object.
+
+=head3 C<plan>
+
+ if ( $result->is_plan ) {
+ print $result->plan;
+ }
+
+This is merely a synonym for C<as_string>.
+
+=head3 C<directive>
+
+ my $directive = $result->directive;
+
+If a SKIP directive is included with the plan, this method will return it.
+
+ 1..0 # SKIP: why bother?
+
+=head3 C<explanation>
+
+ my $explanation = $result->explanation;
+
+If a SKIP directive was included with the plan, this method will return the
+explanation, if any.
+
+=head2 C<pragma> methods
+
+ if ( $result->is_pragma ) { ... }
+
+If the above evaluates as true, the following methods will be available on the
+C<$result> object.
+
+=head3 C<pragmas>
+
+Returns a list of pragmas each of which is a + or - followed by the
+pragma name.
+
+=head2 C<comment> methods
+
+ if ( $result->is_comment ) { ... }
+
+If the above evaluates as true, the following methods will be available on the
+C<$result> object.
+
+=head3 C<comment>
+
+ if ( $result->is_comment ) {
+ my $comment = $result->comment;
+ print "I have something to say: $comment";
+ }
+
+=head2 C<bailout> methods
+
+ if ( $result->is_bailout ) { ... }
+
+If the above evaluates as true, the following methods will be available on the
+C<$result> object.
+
+=head3 C<explanation>
+
+ if ( $result->is_bailout ) {
+ my $explanation = $result->explanation;
+ print "We bailed out because ($explanation)";
+ }
+
+If, and only if, a token is a bailout token, you can get an "explanation" via
+this method. The explanation is the text after the mystical "Bail out!" words
+which appear in the tap output.
+
+=head2 C<unknown> methods
+
+ if ( $result->is_unknown ) { ... }
+
+There are no unique methods for unknown results.
+
+=head2 C<test> methods
+
+ if ( $result->is_test ) { ... }
+
+If the above evaluates as true, the following methods will be available on the
+C<$result> object.
+
+=head3 C<ok>
+
+ my $ok = $result->ok;
+
+Returns the literal text of the C<ok> or C<not ok> status.
+
+=head3 C<number>
+
+ my $test_number = $result->number;
+
+Returns the number of the test, even if the original TAP output did not supply
+that number.
+
+=head3 C<description>
+
+ my $description = $result->description;
+
+Returns the description of the test, if any. This is the portion after the
+test number but before the directive.
+
+=head3 C<directive>
+
+ my $directive = $result->directive;
+
+Returns either C<TODO> or C<SKIP> if either directive was present for a test
+line.
+
+=head3 C<explanation>
+
+ my $explanation = $result->explanation;
+
+If a test had either a C<TODO> or C<SKIP> directive, this method will return
+the accompanying explanation, if present.
+
+ not ok 17 - 'Pigs can fly' # TODO not enough acid
+
+For the above line, the explanation is I<not enough acid>.
+
+=head3 C<is_ok>
+
+ if ( $result->is_ok ) { ... }
+
+Returns a boolean value indicating whether or not the test passed. Remember
+that for TODO tests, the test always passes.
+
+B<Note:> this was formerly C<passed>. The latter method is deprecated and
+will issue a warning.
+
+=head3 C<is_actual_ok>
+
+ if ( $result->is_actual_ok ) { ... }
+
+Returns a boolean value indicating whether or not the test passed, regardless
+of its TODO status.
+
+B<Note:> this was formerly C<actual_passed>. The latter method is deprecated
+and will issue a warning.
+
+=head3 C<is_unplanned>
+
+ if ( $test->is_unplanned ) { ... }
+
+If a test number is greater than the number of planned tests, this method will
+return true. Unplanned tests will I<always> return false for C<is_ok>,
+regardless of whether or not the test C<has_todo> (see
+L<TAP::Parser::Result::Test> for more information about this).
+
+=head3 C<has_skip>
+
+ if ( $result->has_skip ) { ... }
+
+Returns a boolean value indicating whether or not this test had a SKIP
+directive.
+
+=head3 C<has_todo>
+
+ if ( $result->has_todo ) { ... }
+
+Returns a boolean value indicating whether or not this test had a TODO
+directive.
+
+Note that TODO tests I<always> pass. If you need to know whether or not
+they really passed, check the C<is_actual_ok> method.
+
+=head3 C<in_todo>
+
+ if ( $parser->in_todo ) { ... }
+
+True while the most recent result was a TODO. Becomes true before the
+TODO result is returned and stays true until just before the next non-
+TODO test is returned.
+
+=head1 TOTAL RESULTS

+the results and determine what is meaningful to you.

+
+=head3 C<tests_planned>

+
+ $parser->version;

+version number is found version 12 is assumed.
+
+=head3 C<exit>
+
+ $parser->exit;
+
+Once the parser is done, this will return the exit status. If the parser ran

+
+=head3 C<wait>
+
+ $parser->wait;
+
+Once the parser is done, this will return the wait status. If the parser ran
+an executable, it returns the wait status of the executable. Otherwise, this
+merely returns the C<exit> status.
+
+=head2 C<ignore_exit>
+
+ $parser->ignore_exit(1);
+
+Tell the parser to ignore the exit status from the test when determining

+
+Fortunately, all TAP output is perfect. In the event that it is not, this
+method will return parser errors. Note that a junk line which the parser does
+not recognize is C<not> an error. This allows this parser to handle future
+versions of TAP. The following are all TAP errors reported by the parser:
+
+=over 4
+
+=item * Misplaced plan
+
+The plan (for example, '1..5'), must only come at the beginning or end of the
+TAP output.
+
+=item * No plan
+
+Gotta have a plan!
+
+=item * More than one plan
+
+ 1..3
+ ok 1 - input file opened
+ not ok 2 - first line of the input valid # todo some data
+ ok 3 read the rest of the file
+ 1..3
+
+Right. Very funny. Don't do that.
+
+=item * Test numbers out of sequence
+
+ 1..3
+ ok 1 - input file opened
+ not ok 2 - first line of the input valid # todo some data
+ ok 2 read the rest of the file
+
+That last test line above should have the number '3' instead of '2'.
+
+Note that it's perfectly acceptable for some lines to have test numbers and
+others to not have them. However, when a test number is found, it must be in
+sequence. The following is also an error:
+
+ 1..3
+ ok 1 - input file opened
+ not ok - first line of the input valid # todo some data
+ ok 2 read the rest of the file
+
+But this is not:
+

+ not ok - first line of the input valid # todo some data
+ ok 3 read the rest of the file

+
+=head1 CALLBACKS
+
+As mentioned earlier, a "callback" key may be added to the
+C<TAP::Parser> constructor. If present, each callback corresponding to a
+given result type will be called with the result as the argument if the
+C<run> method is used. The callback is expected to be a subroutine
+reference (or anonymous subroutine) which is invoked with the parser
+result as its argument.
+
+ my %callbacks = (
+ test => \&test_callback,
+ plan => \&plan_callback,
+ comment => \&comment_callback,
+ bailout => \&bailout_callback,
+ unknown => \&unknown_callback,
+ );
+
+ my $aggregator = TAP::Parser::Aggregator->new;
+ for my $file ( @test_files ) {
+ my $parser = TAP::Parser->new(
+ {
+ source => $file,
+ callbacks => \%callbacks,
+ }
+ );
+ $parser->run;
+ $aggregator->add( $file, $parser );
+ }
+
+Callbacks may also be added like this:
+
+ $parser->callback( test => \&test_callback );
+ $parser->callback( plan => \&plan_callback );
+
+The following keys allowed for callbacks. These keys are case-sensitive.
+
+=over 4
+
+=item * C<test>
+
+Invoked if C<< $result->is_test >> returns true.
+
+=item * C<version>
+
+Invoked if C<< $result->is_version >> returns true.
+
+=item * C<plan>
+
+Invoked if C<< $result->is_plan >> returns true.
+
+=item * C<comment>
+
+Invoked if C<< $result->is_comment >> returns true.
+
+=item * C<bailout>
+
+Invoked if C<< $result->is_unknown >> returns true.
+
+=item * C<yaml>
+
+Invoked if C<< $result->is_yaml >> returns true.
+
+=item * C<unknown>
+
+Invoked if C<< $result->is_unknown >> returns true.
+
+=item * C<ELSE>
+
+If a result does not have a callback defined for it, this callback will
+be invoked. Thus, if all of the previous result types are specified as
+callbacks, this callback will I<never> be invoked.
+
+=item * C<ALL>
+
+This callback will always be invoked and this will happen for each
+result after one of the above callbacks is invoked. For example, if
+L<Term::ANSIColor> is loaded, you could use the following to color your
+test output:
+
+ my %callbacks = (
+ test => sub {
+ my $test = shift;
+ if ( $test->is_ok && not $test->directive ) {
+ # normal passing test
+ print color 'green';
+ }
+ elsif ( !$test->is_ok ) { # even if it's TODO
+ print color 'white on_red';
+ }
+ elsif ( $test->has_skip ) {
+ print color 'white on_blue';
+
+ }
+ elsif ( $test->has_todo ) {
+ print color 'white';
+ }
+ },
+ ELSE => sub {
+ # plan, comment, and so on (anything which isn't a test line)
+ print color 'black on_white';
+ },
+ ALL => sub {
+ # now print them
+ print shift->as_string;
+ print color 'reset';
+ print "\n";
+ },
+ );
+
+=item * C<EOF>
+
+Invoked when there are no more lines to be parsed. Since there is no
+accompanying L<TAP::Parser::Result> object the C<TAP::Parser> object is
+passed instead.
+
+=back
+
+=head1 TAP GRAMMAR
+
+If you're looking for an EBNF grammar, see L<TAP::Parser::Grammar>.
+
+=head1 BACKWARDS COMPATIBILITY
+
+The Perl-QA list attempted to ensure backwards compatibility with
+L<Test::Harness>. However, there are some minor differences.
+
+=head2 Differences
+
+=over 4
+
+=item * TODO plans
+
+A little-known feature of L<Test::Harness> is that it supported TODO
+lists in the plan:
+
+ 1..2 todo 2
+ ok 1 - We have liftoff
+ not ok 2 - Anti-gravity device activated
+
+Under L<Test::Harness>, test number 2 would I<pass> because it was
+listed as a TODO test on the plan line. However, we are not aware of
+anyone actually using this feature and hard-coding test numbers is
+discouraged because it's very easy to add a test and break the test
+number sequence. This makes test suites very fragile. Instead, the
+following should be used:
+
+ 1..2
+ ok 1 - We have liftoff
+ not ok 2 - Anti-gravity device activated # TODO
+
+=item * 'Missing' tests
+
+It rarely happens, but sometimes a harness might encounter
+'missing tests:
+
+ ok 1
+ ok 2
+ ok 15
+ ok 16
+ ok 17
+
+L<Test::Harness> would report tests 3-14 as having failed. For the
+C<TAP::Parser>, these tests are not considered failed because they've
+never run. They're reported as parse failures (tests out of sequence).
+
+=back
+
+=head1 SUBCLASSING
+
+If you find you need to provide custom functionality (as you would have using
+L<Test::Harness::Straps>), you're in luck: C<TAP::Parser> and friends are
+designed to be easily plugged-into and/or subclassed.
+
+Before you start, it's important to know a few things:
+
+=over 2
+
+=item 1
+
+All C<TAP::*> objects inherit from L<TAP::Object>.
+
+=item 2
+
+Many C<TAP::*> classes have a I<SUBCLASSING> section to guide you.
+
+=item 3
+
+Note that C<TAP::Parser> is designed to be the central "maker" - ie: it is
+responsible for creating most new objects in the C<TAP::Parser::*> namespace.
+
+This makes it possible for you to have a single point of configuring what
+subclasses should be used, which means that in many cases you'll find
+you only need to sub-class one of the parser's components.
+
+The exception to this rule are I<SourceHandlers> & I<Iterators>, but those are
+both created with customizable I<IteratorFactory>.
+
+=item 4
+
+By subclassing, you may end up overriding undocumented methods. That's not
+a bad thing per se, but be forewarned that undocumented methods may change
+without warning from one release to the next - we cannot guarantee backwards
+compatibility. If any I<documented> method needs changing, it will be
+deprecated first, and changed in a later release.
+
+=back
+
+=head2 Parser Components
+
+=head3 Sources
+
+A TAP parser consumes input from a single I<raw source> of TAP, which could come
+from anywhere (a file, an executable, a database, an IO handle, a URI, etc..).
+The source gets bundled up in a L<TAP::Parser::Source> object which gathers some
+meta data about it. The parser then uses a L<TAP::Parser::IteratorFactory> to
+determine which L<TAP::Parser::SourceHandler> to use to turn the raw source
+into a stream of TAP by way of L</Iterators>.
+
+If you simply want C<TAP::Parser> to handle a new source of TAP you probably
+don't need to subclass C<TAP::Parser> itself. Rather, you'll need to create a
+new L<TAP::Parser::SourceHandler> class, and just plug it into the parser using
+the I<sources> param to L</new>. Before you start writing one, read through
+L<TAP::Parser::IteratorFactory> to get a feel for how the system works first.
+
+If you find you really need to use your own iterator factory you can still do
+so without sub-classing C<TAP::Parser> by setting L</iterator_factory_class>.
+
+If you just need to customize the objects on creation, subclass L<TAP::Parser>
+and override L</make_iterator_factory>.
+
+Note that C<make_source> & C<make_perl_source> have been I<DEPRECATED> and
+are now removed.
+
+=head3 Iterators
+
+A TAP parser uses I<iterators> to loop through the I<stream> of TAP read in
+from the I<source> it was given. There are a few types of Iterators available
+by default, all sub-classes of L<TAP::Parser::Iterator>. Choosing which
+iterator to use is the responsibility of the I<iterator factory>, though it
+simply delegates to the I<Source Handler> it uses.
+
+If you're writing your own L<TAP::Parser::SourceHandler>, you may need to
+create your own iterators too. If so you'll need to subclass
+L<TAP::Parser::Iterator>.
+
+Note that L</make_iterator> has been I<DEPRECATED> and is now removed.
+
+=head3 Results
+
+A TAP parser creates L<TAP::Parser::Result>s as it iterates through the
+input I<stream>. There are quite a few result types available; choosing
+which class to use is the responsibility of the I<result factory>.
+
+To create your own result types you have two options:
+
+=over 2
+
+=item option 1
+
+Subclass L<TAP::Parser::Result> and register your new result type/class with
+the default L<TAP::Parser::ResultFactory>.
+
+=item option 2
+
+Subclass L<TAP::Parser::ResultFactory> itself and implement your own
+L<TAP::Parser::Result> creation logic. Then you'll need to customize the
+class used by your parser by setting the C<result_factory_class> parameter.
+See L</new> for more details.
+
+=back
+
+If you need to customize the objects on creation, subclass L<TAP::Parser> and
+override L</make_result>.
+
+=head3 Grammar
+
+L<TAP::Parser::Grammar> is the heart of the parser. It tokenizes the TAP
+input I<stream> and produces results. If you need to customize its behaviour
+you should probably familiarize yourself with the source first. Enough
+lecturing.
+
+Subclass L<TAP::Parser::Grammar> and customize your parser by setting the
+C<grammar_class> parameter. See L</new> for more details.
+
+If you need to customize the objects on creation, subclass L<TAP::Parser> and
+override L</make_grammar>

+ });
+

+
+=head1 DESCRIPTION
+
+C<TAP::Parser::Grammar> tokenizes lines from a L<TAP::Parser::Iterator> and
+constructs L<TAP::Parser::Result> subclasses to represent the tokens.
+
+Do not attempt to use this class directly. It won't make sense. It's mainly
+here to ensure that we will be able to have pluggable grammars when TAP is
+expanded at some future date (plus, this stuff was really cluttering the
+parser).
+

+=head2 Class Methods
+
+=head3 C<new>
+
+ my $grammar = TAP::Parser::Grammar->new({
+ iterator => $iterator,
+ parser => $parser,
+ version => $version,
+ });
+
+Returns L<TAP::Parser> grammar object that will parse the TAP stream from the
+specified iterator. Both C<iterator> and C<parser> are required arguments.
+If C<version> is not set it defaults to C<12> (see L</set_version> for more
+details).

+=head1 TAP GRAMMAR
+
+B<NOTE:> This grammar is slightly out of date. There's still some discussion
+about it and a new one will be provided when we have things better defined.
+
+The L<TAP::Parser> does not use a formal grammar because TAP is essentially a
+stream-based protocol. In fact, it's quite legal to have an infinite stream.
+For the same reason that we don't apply regexes to streams, we're not using a
+formal grammar here. Instead, we parse the TAP in lines.
+
+For purposes for forward compatibility, any result which does not match the
+following grammar is currently referred to as
+L<TAP::Parser::Result::Unknown>. It is I<not> a parse error.
+
+A formal grammar would look similar to the following:
+
+ (*
+ For the time being, I'm cheating on the EBNF by allowing
+ certain terms to be defined by POSIX character classes by
+ using the following syntax:
+
+ digit ::= [:digit:]
+
+ As far as I am aware, that's not valid EBNF. Sue me. I
+ didn't know how to write "char" otherwise (Unicode issues).
+ Suggestions welcome.
+ *)
+
+ tap ::= version? { comment | unknown } leading_plan lines
+ |
+ lines trailing_plan {comment}
+
+ version ::= 'TAP version ' positiveInteger {positiveInteger} "\n"
+
+ leading_plan ::= plan skip_directive? "\n"
+
+ trailing_plan ::= plan "\n"
+
+ plan ::= '1..' nonNegativeInteger
+
+ lines ::= line {line}
+
+ line ::= (comment | test | unknown | bailout ) "\n"
+
+ test ::= status positiveInteger? description? directive?
+
+ status ::= 'not '? 'ok '
+
+ description ::= (character - (digit | '#')) {character - '#'}
+
+ directive ::= todo_directive | skip_directive
+
+ todo_directive ::= hash_mark 'TODO' ' ' {character}
+
+ skip_directive ::= hash_mark 'SKIP' ' ' {character}
+
+ comment ::= hash_mark {character}
+
+ hash_mark ::= '#' {' '}
+
+ bailout ::= 'Bail out!' {character}
+
+ unknown ::= { (character - "\n") }
+
+ (* POSIX character classes and other terminals *)
+
+ digit ::= [:digit:]
+ character ::= ([:print:] - "\n")
+ positiveInteger ::= ( digit - '0' ) {digit}
+ nonNegativeInteger ::= digit {digit}
+

+
+Please see L<TAP::Parser/SUBCLASSING> for a subclassing overview.
+
+If you I<really> want to subclass L<TAP::Parser>'s grammar the best thing to

+=head1 DESCRIPTION
+
+This is a simple iterator wrapper for executing external processes, used by

+won't need to use this module directly.
+
+=head1 METHODS
+
+=head2 Class Methods
+
+=head3 C<new>
+
+Create an iterator. Expects one argument containing a hashref of the form:
+
+ command => \@command_to_execute
+ merge => $attempt_merge_stderr_and_stdout?
+ setup => $callback_to_setup_command
+ teardown => $callback_to_teardown_command
+
+Tries to uses L<IPC::Open3> & L<IO::Select> to communicate with the spawned
+process if they are available. Falls back onto C<open()>.
+
+=head2 Instance Methods
+
+=head3 C<next>
+
+Iterate through the process output, of course.
+
+=head3 C<next_raw>
+
+Iterate raw input without applying any fixes for quirky input syntax.
+
+=head3 C<wait>
+
+Get the wait status for this iterator's process.
+

+
+Get the exit status for this iterator's process.

+ # override source detection algorithm

+C<TAP::Parser::Multiplexer> gathers input from multiple TAP::Parsers.
+Internally it calls select on the input file handles for those parsers
+to wait for one or more of them to have input available.
+
+See L<TAP::Harness> for an example of its use.

+
+=head1 SYNOPSIS
+
+ # abstract class - not meant to be used directly
+ # see TAP::Parser::ResultFactory for preferred usage
+
+ # directly:
+ use TAP::Parser::Result;
+ my $token = {...};
+ my $result = TAP::Parser::Result->new( $token );
+
+=head2 DESCRIPTION
+
+This is a simple base class used by L<TAP::Parser> to store objects that
+represent the current bit of test output data from TAP (usually a single
+line). Unless you're subclassing, you probably won't need to use this module
+directly.
+
+=head2 METHODS
+
+=head3 C<new>
+
+ # see TAP::Parser::ResultFactory for preferred usage
+
+ # to use directly:
+ my $result = TAP::Parser::Result->new($token);

+ # assign to a hash slice to make a shallow copy of the token.
+ # I guess we could assign to the hash as (by default) there are not
+ # contents, but that seems less helpful if someone wants to subclass us

+=head1 SUBCLASSING
+
+Please see L<TAP::Parser/SUBCLASSING> for a subclassing overview.
+
+Remember: if you want your subclass to be automatically used by the parser,
+you'll have to register it with L<TAP::Parser::ResultFactory/register_type>.
+
+If you're creating a completely new result I<type>, you'll probably need to
+subclass L<TAP::Parser::Grammar> too, or else it'll never get used.
+
+=head2 Example
+
+ package MyResult;
+
+ use strict;
+
+ use base 'TAP::Parser::Result';
+
+ # register with the factory:
+ TAP::Parser::ResultFactory->register_type( 'my_type' => __PACKAGE__ );
+
+ sub as_string { 'My results all look the same' }

+
+This is a simple factory class which returns a L<TAP::Parser::Result> subclass
+representing the current bit of test data from TAP (usually a single line).
+It is used primarily by L<TAP::Parser::Grammar>. Unless you're subclassing,
+you probably won't need to use this module directly.
+
+=head2 METHODS
+
+=head2 Class Methods
+
+=head3 C<new>
+
+Creates a new factory class.
+I<Note:> You currently don't need to instantiate a factory in order to use it.
+
+=head3 C<make_result>
+
+Returns an instance the appropriate class for the test token passed in.
+
+ my $result = TAP::Parser::ResultFactory->make_result($token);

+
+Takes one argument: C<$type>. Returns the class for this $type, or C<croak>s
+with an error.
+
+=head3 C<register_type>
+
+Takes two arguments: C<$type>, C<$class>
+
+This lets you override an existing type with your own custom type, or register
+a completely new type, eg:
+
+ # create a custom result type:
+ package MyResult;
+ use strict;
+ use base 'TAP::Parser::Result';
+
+ # register with the factory:
+ TAP::Parser::ResultFactory->register_type( 'my_type' => __PACKAGE__ );
+
+ # use it:
+ my $r = TAP::Parser::ResultFactory->( { type => 'my_type' } );
+
+Your custom type should then be picked up automatically by the L<TAP::Parser>.

+=head1 SUBCLASSING
+
+Please see L<TAP::Parser/SUBCLASSING> for a subclassing overview.
+
+There are a few things to bear in mind when creating your own
+C<ResultFactory>:
+
+=over 4
+
+=item 1
+
+The factory itself is never instantiated (this I<may> change in the future).
+This means that C<_initialize> is never called.
+
+=item 2
+
+C<TAP::Parser::Result-E<gt>new> is never called, $tokens are reblessed.
+This I<will> change in a future version!
+
+=item 3
+
+L<TAP::Parser::Result> subclasses will register themselves with
+L<TAP::Parser::ResultFactory> directly:
+
+ package MyFooResult;
+ TAP::Parser::ResultFactory->register_type( foo => __PACKAGE__ );
+
+Of course, it's up to you to decide whether or not to ignore them.

+
+TAP::Parser::Scheduler - Schedule tests during parallel testing
+
+=head1 VERSION
+
+Version 3.48
+
+=cut
+
+our $VERSION = '3.48';
+
+=head1 SYNOPSIS
+
+ use TAP::Parser::Scheduler;
+
+=head1 DESCRIPTION
+
+=head1 METHODS
+
+=head2 Class Methods
+
+=head3 C<new>
+
+ my $sched = TAP::Parser::Scheduler->new(tests => \@tests);
+ my $sched = TAP::Parser::Scheduler->new(
+ tests => [ ['t/test_name.t','Test Description'], ... ],
+ rules => \%rules,
+ );
+
+Given 'tests' and optional 'rules' as input, returns a new
+C<TAP::Parser::Scheduler> object. Each member of C<@tests> should be either a
+a test file name, or a two element arrayref, where the first element is a test
+file name, and the second element is a test description. By default, we'll use
+the test name as the description.
+
+The optional C<rules> attribute provides direction on which tests should be run
+in parallel and which should be run sequentially. If no rule data structure is
+provided, a default data structure is used which makes every test eligible to
+be run in parallel:
+
+ { par => '**' },
+
+The rules data structure is documented more in the next section.
+
+=head2 Rules data structure
+
+The "C<rules>" data structure is the the heart of the scheduler. It allows you
+to express simple rules like "run all tests in sequence" or "run all tests in
+parallel except these five tests.". However, the rules structure also supports
+glob-style pattern matching and recursive definitions, so you can also express
+arbitarily complicated patterns.
+
+The rule must only have one top level key: either 'par' for "parallel" or 'seq'
+for "sequence".
+
+Values must be either strings with possible glob-style matching, or arrayrefs
+of strings or hashrefs which follow this pattern recursively.
+
+Every element in an arrayref directly below a 'par' key is eligible to be run
+in parallel, while vavalues directly below a 'seq' key must be run in sequence.
+
+=head3 Rules examples
+
+Here are some examples:
+
+ # All tests be run in parallel (the default rule)
+ { par => '**' },
+
+ # Run all tests in sequence, except those starting with "p"
+ { par => 't/p*.t' },
+
+ # Run all tests in parallel, except those starting with "p"
+ {
+ seq => [
+ { seq => 't/p*.t' },
+ { par => '**' },
+ ],
+ }
+
+ # Run some startup tests in sequence, then some parallel tests then some
+ # teardown tests in sequence.
+ {
+ seq => [
+ { seq => 't/startup/*.t' },
+ { par => ['t/a/*.t','t/b/*.t','t/c/*.t'], }
+ { seq => 't/shutdown/*.t' },
+ ],
+ },
+
+
+=head3 Rules resolution
+
+=over 4
+
+=item * By default, all tests are eligible to be run in parallel. Specifying any of your own rules removes this one.
+
+=item * "First match wins". The first rule that matches a test will be the one that applies.
+
+=item * Any test which does not match a rule will be run in sequence at the end of the run.
+
+=item * The existence of a rule does not imply selecting a test. You must still specify the tests to run.
+
+=item * Specifying a rule to allow tests to run in parallel does not make the run in parallel. You still need specify the number of parallel C<jobs> in your Harness object.
+
+=back
+
+=head3 Glob-style pattern matching for rules
+
+We implement our own glob-style pattern matching. Here are the patterns it supports:
+
+ ** is any number of characters, including /, within a pathname
+ * is zero or more characters within a filename/directory name
+ ? is exactly one character within a filename/directory name
+ {foo,bar,baz} is any of foo, bar or baz.
+ \ is an escape character

+=head1 DESCRIPTION
+
+A TAP I<source> is something that produces a stream of TAP for the parser to
+consume, such as an executable file, a text file, an archive, an IO handle, a
+database, etc. C<TAP::Parser::Source>s encapsulate these I<raw> sources, and
+provide some useful meta data about them. They are used by
+L<TAP::Parser::SourceHandler>s, which do whatever is required to produce &
+capture a stream of TAP from the I<raw> source, and package it up in a
+L<TAP::Parser::Iterator> for the parser to consume.
+
+Unless you're writing a new L<TAP::Parser::SourceHandler>, a plugin or
+subclassing L<TAP::Parser>, you probably won't need to use this module directly.

+=head1 DESCRIPTION
+
+This is an abstract base class for L<TAP::Parser::Source> handlers / handlers.
+
+A C<TAP::Parser::SourceHandler> does whatever is necessary to produce & capture
+a stream of TAP from the I<raw> source, and package it up in a
+L<TAP::Parser::Iterator> for the parser to consume.
+
+C<SourceHandlers> must implement the I<source detection & handling> interface
+used by L<TAP::Parser::IteratorFactory>. At 2 methods, the interface is pretty
+simple: L</can_handle> and L</make_source>.
+
+Unless you're writing a new L<TAP::Parser::SourceHandler>, a plugin, or
+subclassing L<TAP::Parser>, you probably won't need to use this module directly.

+

+can be handled. For example, C<0> means the source cannot handle it, C<0.5>
+means it may be able to, and C<1> means it definitely can. See

+=head1 SUBCLASSING
+
+Please see L<TAP::Parser/SUBCLASSING> for a subclassing overview, and any
+of the subclasses that ship with this module as an example. What follows is
+a quick overview.
+
+Start by familiarizing yourself with L<TAP::Parser::Source> and
+L<TAP::Parser::IteratorFactory>. L<TAP::Parser::SourceHandler::RawTAP> is
+the easiest sub-class to use as an example.
+
+It's important to point out that if you want your subclass to be automatically
+used by L<TAP::Parser> you'll have to and make sure it gets loaded somehow.
+If you're using L<prove> you can write an L<App::Prove> plugin. If you're
+using L<TAP::Parser> or L<TAP::Harness> directly (e.g. through a custom script,
+L<ExtUtils::MakeMaker>, or L<Module::Build>) you can use the C<config> option
+which will cause L<TAP::Parser::IteratorFactory/load_sources> to load your
+subclass).
+
+Don't forget to register your class with
+L<TAP::Parser::IteratorFactory/register_handler>.

+ use TAP::Parser::Source;
+ use TAP::Parser::SourceHandler::RawTAP;
+
+ my $source = TAP::Parser::Source->new->raw( \"1..1\nok 1\n" );
+ $source->assemble_meta;

+ my $class = 'TAP::Parser::SourceHandler::RawTAP';
+ my $vote = $class->can_handle( $source );
+ my $iter = $class->make_iterator( $source );
+
+=head1 DESCRIPTION
+
+This is a I<raw TAP output> L<TAP::Parser::SourceHandler> - it has 2 jobs:
+
+1. Figure out if the L<TAP::Parser::Source> it's given is raw TAP output
+(L</can_handle>).
+
+2. Creates an iterator for raw TAP output (L</make_iterator>).
+
+Unless you're writing a plugin or subclassing L<TAP::Parser>, you probably
+won't need to use this module directly.
+
+=head1 METHODS
+
+=head2 Class Methods
+
+=head3 C<can_handle>
+
+ my $vote = $class->can_handle( $source );
+
+Only votes if $source is an array, or a scalar with newlines. Casts the
+following votes:
+
+ 0.9 if it's a scalar with '..' in it
+ 0.7 if it's a scalar with 'ok' in it
+ 0.3 if it's just a scalar with newlines
+ 0.5 if it's an array

+ elsif ( $meta->{is_array} ) {
+ return 0.5;
+ }
+ return 0;
+}
+
+=head3 C<make_iterator>
+
+ my $iterator = $class->make_iterator( $source );
+
+Returns a new L<TAP::Parser::Iterator::Array> for the source.
+C<$source-E<gt>raw> must be an array ref, or a scalar ref.
+
+C<croak>s on error.
