NAME
       TAP::Parser::Aggregator - Aggregate TAP::Parser results

VERSION
       Version 3.28

SYNOPSIS
	   use TAP::Parser::Aggregator;

	   my $aggregate = TAP::Parser::Aggregator->new;
	   $aggregate->add( 't/00-load.t', $load_parser );
	   $aggregate->add( 't/10-lex.t',  $lex_parser	);

	   my $summary = <<'END_SUMMARY';
	   Passed:  %s
	   Failed:  %s
	   Unexpectedly succeeded: %s
	   END_SUMMARY
	   printf $summary,
		  scalar $aggregate->passed,
		  scalar $aggregate->failed,
		  scalar $aggregate->todo_passed;

DESCRIPTION
       "TAP::Parser::Aggregator" collects parser objects and allows reporting/querying their
       aggregate results.

METHODS
   Class Methods
       "new"

	my $aggregate = TAP::Parser::Aggregator->new;

       Returns a new "TAP::Parser::Aggregator" object.

   Instance Methods
       "add"

	 $aggregate->add( $description => $parser );

       The $description is usually a test file name (but only by convention.)  It is used as a
       unique identifier (see e.g.  "parsers".)  Reusing a description is a fatal error.

       The $parser is a TAP::Parser object.

       "parsers"

	 my $count   = $aggregate->parsers;
	 my @parsers = $aggregate->parsers;
	 my @parsers = $aggregate->parsers(@descriptions);

       In scalar context without arguments, this method returns the number of parsers aggregated.
       In list context without arguments, returns the parsers in the order they were added.

       If @descriptions is given, these correspond to the keys used in each call to the add()
       method.	Returns an array of the requested parsers (in the requested order) in list
       context or an array reference in scalar context.

       Requesting an unknown identifier is a fatal error.

       "descriptions"

       Get an array of descriptions in the order in which they were added to the aggregator.

       "start"

       Call "start" immediately before adding any results to the aggregator.  Among other times
       it records the start time for the test run.

       "stop"

       Call "stop" immediately after adding all test results to the aggregator.

       "elapsed"

       Elapsed returns a Benchmark object that represents the running time of the aggregated
       tests. In order for "elapsed" to be valid you must call "start" before running the tests
       and "stop" immediately afterwards.

       "elapsed_timestr"

       Returns a formatted string representing the runtime returned by "elapsed()".  This lets
       the caller not worry about Benchmark.

       "all_passed"

       Return true if all the tests passed and no parse errors were detected.

       "get_status"

       Get a single word describing the status of the aggregated tests.  Depending on the outcome
       of the tests returns 'PASS', 'FAIL' or 'NOTESTS'. This token is understood by
       CPAN::Reporter.

   Summary methods
       Each of the following methods will return the total number of corresponding tests if
       called in scalar context.  If called in list context, returns the descriptions of the
       parsers which contain the corresponding tests (see "add" for an explanation of
       description.

       o   failed

       o   parse_errors

       o   passed

       o   planned

       o   skipped

       o   todo

       o   todo_passed

       o   wait

       o   exit

       For example, to find out how many tests unexpectedly succeeded (TODO tests which passed
       when they shouldn't):

	my $count	 = $aggregate->todo_passed;
	my @descriptions = $aggregate->todo_passed;

       Note that "wait" and "exit" are the totals of the wait and exit statuses of each of the
       tests. These values are totalled only to provide a true value if any of them are non-zero.

       "total"

	 my $tests_run = $aggregate->total;

       Returns the total number of tests run.

       "has_problems"

	 if ( $parser->has_problems ) {
	     ...
	 }

       Identical to "has_errors", but also returns true if any TODO tests unexpectedly succeeded.
       This is more akin to "warnings".

       "has_errors"

	 if ( $parser->has_errors ) {
	     ...
	 }

       Returns true if any of the parsers failed.  This includes:

       o   Failed tests

       o   Parse errors

       o   Bad exit or wait status

       "todo_failed"

	 # deprecated in favor of 'todo_passed'.  This method was horribly misnamed.

       This was a badly misnamed method.  It indicates which TODO tests unexpectedly succeeded.
       Will now issue a warning and call "todo_passed".
