NAME

TAP::Parser - Parse TAP output

VERSION

Version 3.17

SYNOPSIS

  1.     use TAP::Parser;
  3.     my $parser = TAP::Parser->new( { source => $source } );
  5.     while ( my $result = $parser->next ) {
  6.         print $result->as_string;
  7.     }

DESCRIPTION

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 examples/ .

There's a wiki dedicated to the Test Anything Protocol:

http://testanything.org

It includes the TAP::Parser Cookbook:

http://testanything.org/wiki/index.php/TAP::Parser_Cookbook

METHODS

Class Methods

new 

  1.  my $parser = TAP::Parser->new(\%args);

Returns a new TAP::Parser object.

The arguments should be a hashref with one of the following keys:

  • source

    This is the preferred method of passing arguments to the constructor. To determine how to handle the source, the following steps are taken.

    If the source contains a newline, it's assumed to be a string of raw TAP output.

    If the source is a reference, it's assumed to be something to pass to the TAP::Parser::Iterator::Stream constructor. This is used internally and you should not use it.

    Otherwise, the parser does a -e check to see if the source exists. If so, it attempts to execute the source and read the output as a stream. This is by far the preferred method of using the parser.

    1.  foreach my $file ( @test_files ) {
    2.      my $parser = TAP::Parser->new( { source => $file } );
    3.      # do stuff with the parser
    4.  }
  • tap

    The value should be the complete TAP output.

  • exec

    If passed an array reference, will attempt to create the iterator by passing a TAP::Parser::Source object to TAP::Parser::Iterator::Source, using the array reference strings as the command arguments to IPC::Open3::open3:

    1.  exec => [ '/usr/bin/ruby', 't/my_test.rb' ]

    Note that source and exec are mutually exclusive.

The following keys are optional.

  • callback

    If present, each callback corresponding to a given result type will be called with the result as the argument if the run method is used:

    1.  my %callbacks = (
    2.      test    => \&test_callback,
    3.      plan    => \&plan_callback,
    4.      comment => \&comment_callback,
    5.      bailout => \&bailout_callback,
    6.      unknown => \&unknown_callback,
    7.  );
    9.  my $aggregator = TAP::Parser::Aggregator->new;
    10.  foreach my $file ( @test_files ) {
    11.      my $parser = TAP::Parser->new(
    12.          {
    13.              source    => $file,
    14.              callbacks => \%callbacks,
    15.          }
    16.      );
    17.      $parser->run;
    18.      $aggregator->add( $file, $parser );
    19.  }
  • switches

    If using a Perl file as a source, optional switches may be passed which will be used when invoking the perl executable.

    1.  my $parser = TAP::Parser->new( {
    2.      source   => $test_file,
    3.      switches => '-Ilib',
    4.  } );
  • test_args

    Used in conjunction with the source option to supply a reference to an @ARGV style array of arguments to pass to the test program.

  • spool

    If passed a filehandle will write a copy of all parsed TAP to that handle.

  • 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.

  • source_class

    This option was introduced to let you easily customize which source class the parser should use. It defaults to TAP::Parser::Source.

    See also make_source.

  • perl_source_class

    This option was introduced to let you easily customize which perl source class the parser should use. It defaults to TAP::Parser::Source::Perl.

    See also make_perl_source.

  • grammar_class

    This option was introduced to let you easily customize which grammar class the parser should use. It defaults to TAP::Parser::Grammar.

    See also make_grammar.

  • iterator_factory_class

    This option was introduced to let you easily customize which iterator factory class the parser should use. It defaults to TAP::Parser::IteratorFactory.

    See also make_iterator.

  • result_factory_class

    This option was introduced to let you easily customize which result factory class the parser should use. It defaults to TAP::Parser::ResultFactory.

    See also make_result.

Instance Methods

next

  1.   my $parser = TAP::Parser->new( { source => $file } );
  2.   while ( my $result = $parser->next ) {
  3.       print $result->as_string, "\n";
  4.   }

This method returns the results of the parsing, one result at a time. Note that it is destructive. You can't rewind and examine previous results.

If callbacks are used, they will be issued before this call returns.

Each result returned is a subclass of TAP::Parser::Result. See that module and related classes for more information on how to use them.

run 

  1.   $parser->run;

This method merely runs the parser and parses all of the TAP.

make_source

Make a new TAP::Parser::Source object and return it. Passes through any arguments given.

The source_class can be customized, as described in new.

make_perl_source

Make a new TAP::Parser::Source::Perl object and return it. Passes through any arguments given.

The perl_source_class can be customized, as described in new.

make_grammar

Make a new TAP::Parser::Grammar object and return it. Passes through any arguments given.

The grammar_class can be customized, as described in new.

make_iterator

Make a new TAP::Parser::Iterator object using the parser's TAP::Parser::IteratorFactory, and return it. Passes through any arguments given.

The iterator_factory_class can be customized, as described in new.

make_result

Make a new TAP::Parser::Result object using the parser's TAP::Parser::ResultFactory, and return it. Passes through any arguments given.

The result_factory_class can be customized, as described in new.

INDIVIDUAL RESULTS

If you've read this far in the docs, you've seen this:

  1.     while ( my $result = $parser->next ) {
  2.         print $result->as_string;
  3.     }

Each result returned is a TAP::Parser::Result subclass, referred to as result types.

Result types

Basically, you fetch individual results from the TAP. The six types, with examples of each, are as follows:

  • Version 
    1.  TAP version 12
  • Plan 
    1.  1..42
  • Pragma 
    1.  pragma +strict
  • Test 
    1.  ok 3 - We should start with some foobar!
  • Comment 
    1.  # Hope we don't use up the foobar.
  • Bailout 
    1.  Bail out!  We ran out of foobar!
  • Unknown 
    1.  ... yo, this ain't TAP! ...

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.

Common type methods

type

Returns the type of result, such as comment or test .

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 raw method.

raw

Returns the original line of text which was parsed.

is_plan

Indicates whether or not this is the test plan line.

is_test

Indicates whether or not this is a test line.

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 merge option.

is_bailout

Indicates whether or not this is bailout line.

is_yaml

Indicates whether or not the current item is a YAML block.

is_unknown

Indicates whether or not the current line could be parsed.

is_ok 

  1.   if ( $result->is_ok ) { ... }

Reports whether or not a given result has passed. Anything which is not a test result returns true. This is merely provided as a convenient shortcut which allows you to do this:

  1.  my $parser = TAP::Parser->new( { source => $source } );
  2.  while ( my $result = $parser->next ) {
  3.      # only print failing results
  4.      print $result->as_string unless $result->is_ok;
  5.  }

plan methods

  1.  if ( $result->is_plan ) { ... }

If the above evaluates as true, the following methods will be available on the $result object.

plan 

  1.   if ( $result->is_plan ) {
  2.      print $result->plan;
  3.   }

This is merely a synonym for as_string .

directive 

  1.  my $directive = $result->directive;

If a SKIP directive is included with the plan, this method will return it.

  1.  1..0 # SKIP: why bother?

explanation 

  1.  my $explanation = $result->explanation;

If a SKIP directive was included with the plan, this method will return the explanation, if any.

pragma methods

  1.  if ( $result->is_pragma ) { ... }

If the above evaluates as true, the following methods will be available on the $result object.

pragmas

Returns a list of pragmas each of which is a + or - followed by the pragma name.

commment methods

  1.  if ( $result->is_comment ) { ... }

If the above evaluates as true, the following methods will be available on the $result object.

comment 

  1.   if ( $result->is_comment ) {
  2.       my $comment = $result->comment;
  3.       print "I have something to say:  $comment";
  4.   }

bailout methods

  1.  if ( $result->is_bailout ) { ... }

If the above evaluates as true, the following methods will be available on the $result object.

explanation 

  1.   if ( $result->is_bailout ) {
  2.       my $explanation = $result->explanation;
  3.       print "We bailed out because ($explanation)";
  4.   }

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.

unknown methods

  1.  if ( $result->is_unknown ) { ... }

There are no unique methods for unknown results.

test methods

  1.  if ( $result->is_test ) { ... }

If the above evaluates as true, the following methods will be available on the $result object.

ok 

  1.   my $ok = $result->ok;

Returns the literal text of the ok or not ok status.

number 

  1.   my $test_number = $result->number;

Returns the number of the test, even if the original TAP output did not supply that number.

description 

  1.   my $description = $result->description;

Returns the description of the test, if any. This is the portion after the test number but before the directive.

directive 

  1.   my $directive = $result->directive;

Returns either TODO or SKIP if either directive was present for a test line.

explanation 

  1.   my $explanation = $result->explanation;

If a test had either a TODO or SKIP directive, this method will return the accompanying explantion, if present.

  1.   not ok 17 - 'Pigs can fly' # TODO not enough acid

For the above line, the explanation is not enough acid.

is_ok 

  1.   if ( $result->is_ok ) { ... }

Returns a boolean value indicating whether or not the test passed. Remember that for TODO tests, the test always passes.

Note: this was formerly passed . The latter method is deprecated and will issue a warning.

is_actual_ok 

  1.   if ( $result->is_actual_ok ) { ... }

Returns a boolean value indicating whether or not the test passed, regardless of its TODO status.

Note: this was formerly actual_passed . The latter method is deprecated and will issue a warning.

is_unplanned 

  1.   if ( $test->is_unplanned ) { ... }

If a test number is greater than the number of planned tests, this method will return true. Unplanned tests will always return false for is_ok , regardless of whether or not the test has_todo (see TAP::Parser::Result::Test for more information about this).

has_skip 

  1.   if ( $result->has_skip ) { ... }

Returns a boolean value indicating whether or not this test had a SKIP directive.

has_todo 

  1.   if ( $result->has_todo ) { ... }

Returns a boolean value indicating whether or not this test had a TODO directive.

Note that TODO tests always pass. If you need to know whether or not they really passed, check the is_actual_ok method.

in_todo 

  1.   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.

TOTAL RESULTS

After parsing the TAP, there are many methods available to let you dig through the results and determine what is meaningful to you.

Individual Results

These results refer to individual tests which are run.

passed 

  1.  my @passed = $parser->passed; # the test numbers which passed
  2.  my $passed = $parser->passed; # the number of tests which passed

This method lets you know which (or how many) tests passed. If a test failed but had a TODO directive, it will be counted as a passed test.

failed 

  1.  my @failed = $parser->failed; # the test numbers which failed
  2.  my $failed = $parser->failed; # the number of tests which failed

This method lets you know which (or how many) tests failed. If a test passed but had a TODO directive, it will NOT be counted as a failed test.

actual_passed 

  1.  # the test numbers which actually passed
  2.  my @actual_passed = $parser->actual_passed;
  4.  # the number of tests which actually passed
  5.  my $actual_passed = $parser->actual_passed;

This method lets you know which (or how many) tests actually passed, regardless of whether or not a TODO directive was found.

actual_ok

This method is a synonym for actual_passed .

actual_failed 

  1.  # the test numbers which actually failed
  2.  my @actual_failed = $parser->actual_failed;
  4.  # the number of tests which actually failed
  5.  my $actual_failed = $parser->actual_failed;

This method lets you know which (or how many) tests actually failed, regardless of whether or not a TODO directive was found.

todo 

  1.  my @todo = $parser->todo; # the test numbers with todo directives
  2.  my $todo = $parser->todo; # the number of tests with todo directives

This method lets you know which (or how many) tests had TODO directives.

todo_passed 

  1.  # the test numbers which unexpectedly succeeded
  2.  my @todo_passed = $parser->todo_passed;
  4.  # the number of tests which unexpectedly succeeded
  5.  my $todo_passed = $parser->todo_passed;

This method lets you know which (or how many) tests actually passed but were declared as "TODO" tests.

todo_failed 

  1.   # 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 .

skipped 

  1.  my @skipped = $parser->skipped; # the test numbers with SKIP directives
  2.  my $skipped = $parser->skipped; # the number of tests with SKIP directives

This method lets you know which (or how many) tests had SKIP directives.

Pragmas

pragma

Get or set a pragma. To get the state of a pragma:

  1.   if ( $p->pragma('strict') ) {
  2.       # be strict
  3.   }

To set the state of a pragma:

  1.   $p->pragma('strict', 1); # enable strict mode

pragmas

Get a list of all the currently enabled pragmas:

  1.   my @pragmas_enabled = $p->pragmas;

Summary Results

These results are "meta" information about the total results of an individual test program.

plan 

  1.  my $plan = $parser->plan;

Returns the test plan, if found.

good_plan

Deprecated. Use is_good_plan instead.

is_good_plan 

  1.   if ( $parser->is_good_plan ) { ... }

Returns a boolean value indicating whether or not the number of tests planned matches the number of tests run.

Note: this was formerly good_plan . The latter method is deprecated and will issue a warning.

And since we're on that subject ...

tests_planned 

  1.   print $parser->tests_planned;

Returns the number of tests planned, according to the plan. For example, a plan of '1..17' will mean that 17 tests were planned.

tests_run 

  1.   print $parser->tests_run;

Returns the number of tests which actually were run. Hopefully this will match the number of $parser->tests_planned .

skip_all

Returns a true value (actually the reason for skipping) if all tests were skipped.

start_time

Returns the time when the Parser was created.

end_time

Returns the time when the end of TAP input was seen.

has_problems 

  1.   if ( $parser->has_problems ) {
  2.       ...
  3.   }

This is a 'catch-all' method which returns true if any tests have currently failed, any TODO tests unexpectedly succeeded, or any parse errors occurred.

version 

  1.   $parser->version;

Once the parser is done, this will return the version number for the parsed TAP. Version numbers were introduced with TAP version 13 so if no version number is found version 12 is assumed.

exit

  1.   $parser->exit;

Once the parser is done, this will return the exit status. If the parser ran an executable, it returns the exit status of the executable.

wait

  1.   $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 mererely returns the exit status.

ignore_exit 

  1.   $parser->ignore_exit(1);

Tell the parser to ignore the exit status from the test when determining whether the test passed. Normally tests with non-zero exit status are considered to have failed even if all individual tests passed. In cases where it is not possible to control the exit value of the test script use this option to ignore it.

parse_errors 

  1.  my @errors = $parser->parse_errors; # the parser errors
  2.  my $errors = $parser->parse_errors; # the number of parser_errors

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 not an error. This allows this parser to handle future versions of TAP. The following are all TAP errors reported by the parser:

  • Misplaced plan

    The plan (for example, '1..5'), must only come at the beginning or end of the TAP output.

  • No plan

    Gotta have a plan!

  • More than one plan 
    1.  1..3
    2.  ok 1 - input file opened
    3.  not ok 2 - first line of the input valid # todo some data
    4.  ok 3 read the rest of the file
    5.  1..3

    Right. Very funny. Don't do that.

  • Test numbers out of sequence 
    1.  1..3
    2.  ok 1 - input file opened
    3.  not ok 2 - first line of the input valid # todo some data
    4.  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.  1..3
    2.  ok 1 - input file opened
    3.  not ok - first line of the input valid # todo some data
    4.  ok 2 read the rest of the file

    But this is not:

    1.  1..3
    2.  ok  - input file opened
    3.  not ok - first line of the input valid # todo some data
    4.  ok 3 read the rest of the file

get_select_handles

Get an a list of file handles which can be passed to select to determine the readiness of this parser.

delete_spool

Delete and return the spool.

  1.   my $fh = $parser->delete_spool;

CALLBACKS

As mentioned earlier, a "callback" key may be added to the TAP::Parser constructor. If present, each callback corresponding to a given result type will be called with the result as the argument if the 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.

  1.  my %callbacks = (
  2.      test    => \&test_callback,
  3.      plan    => \&plan_callback,
  4.      comment => \&comment_callback,
  5.      bailout => \&bailout_callback,
  6.      unknown => \&unknown_callback,
  7.  );
  9.  my $aggregator = TAP::Parser::Aggregator->new;
  10.  foreach my $file ( @test_files ) {
  11.      my $parser = TAP::Parser->new(
  12.          {
  13.              source    => $file,
  14.              callbacks => \%callbacks,
  15.          }
  16.      );
  17.      $parser->run;
  18.      $aggregator->add( $file, $parser );
  19.  }

Callbacks may also be added like this:

  1.  $parser->callback( test => \&test_callback );
  2.  $parser->callback( plan => \&plan_callback );

The following keys allowed for callbacks. These keys are case-sensitive.

  • test

    Invoked if $result->is_test returns true.

  • version

    Invoked if $result->is_version returns true.

  • plan

    Invoked if $result->is_plan returns true.

  • comment

    Invoked if $result->is_comment returns true.

  • bailout

    Invoked if $result->is_unknown returns true.

  • yaml

    Invoked if $result->is_yaml returns true.

  • unknown

    Invoked if $result->is_unknown returns true.

  • 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 never be invoked.

  • 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 Term::ANSIColor is loaded, you could use the following to color your test output:

    1.  my %callbacks = (
    2.      test => sub {
    3.          my $test = shift;
    4.          if ( $test->is_ok && not $test->directive ) {
    5.              # normal passing test
    6.              print color 'green';
    7.          }
    8.          elsif ( !$test->is_ok ) {    # even if it's TODO
    9.              print color 'white on_red';
    10.          }
    11.          elsif ( $test->has_skip ) {
    12.              print color 'white on_blue';
    14.          }
    15.          elsif ( $test->has_todo ) {
    16.              print color 'white';
    17.          }
    18.      },
    19.      ELSE => sub {
    20.          # plan, comment, and so on (anything which isn't a test line)
    21.          print color 'black on_white';
    22.      },
    23.      ALL => sub {
    24.          # now print them
    25.          print shift->as_string;
    26.          print color 'reset';
    27.          print "\n";
    28.      },
    29.  );
  • EOF

    Invoked when there are no more lines to be parsed. Since there is no accompanying TAP::Parser::Result object the TAP::Parser object is passed instead.

TAP GRAMMAR

If you're looking for an EBNF grammar, see TAP::Parser::Grammar.

BACKWARDS COMPATABILITY

The Perl-QA list attempted to ensure backwards compatability with Test::Harness. However, there are some minor differences.

Differences

  • TODO plans

    A little-known feature of Test::Harness is that it supported TODO lists in the plan:

    1.  1..2 todo 2
    2.  ok 1 - We have liftoff
    3.  not ok 2 - Anti-gravity device activated

    Under Test::Harness, test number 2 would 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.  1..2
    2.  ok 1 - We have liftoff
    3.  not ok 2 - Anti-gravity device activated # TODO
  • 'Missing' tests

    It rarely happens, but sometimes a harness might encounter 'missing tests:

    1.  ok 1
    2.  ok 2
    3.  ok 15
    4.  ok 16
    5.  ok 17

    Test::Harness would report tests 3-14 as having failed. For the TAP::Parser , these tests are not considered failed because they've never run. They're reported as parse failures (tests out of sequence).

SUBCLASSING

If you find you need to provide custom functionality (as you would have using Test::Harness::Straps), you're in luck: TAP::Parser and friends are designed to be easily subclassed.

Before you start, it's important to know a few things:

1

All TAP::* objects inherit from TAP::Object.

2

Most TAP::* classes have a SUBCLASSING section to guide you.

3

Note that TAP::Parser is designed to be the central 'maker' - ie: it is responsible for creating new objects in the TAP::Parser::* namespace.

This makes it possible for you to have a single point of configuring what subclasses should be used, which in turn means that in many cases you'll find you only need to sub-class one of the parser's components.

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 compatability. If any documented method needs changing, it will be deprecated first, and changed in a later release.

Parser Components

Sources

A TAP parser consumes input from a source. There are currently two types of sources: TAP::Parser::Source for general non-perl commands, and TAP::Parser::Source::Perl. You can subclass both of them. You'll need to customize your parser by setting the source_class & perl_source_class parameters. See new for more details.

If you need to customize the objects on creation, subclass TAP::Parser and override make_source or make_perl_source.

Iterators

A TAP parser uses iterators to loop through the stream provided by the parser's source. There are quite a few types of Iterators available. Choosing which class to use is the responsibility of the iterator factory.

To create your own iterators you'll have to subclass TAP::Parser::IteratorFactory and TAP::Parser::Iterator. Then you'll need to customize the class used by your parser by setting the iterator_factory_class parameter. See new for more details.

If you need to customize the objects on creation, subclass TAP::Parser and override make_iterator.

Results

A TAP parser creates TAP::Parser::Results as it iterates through the input stream. There are quite a few result types available; choosing which class to use is the responsibility of the result factory.

To create your own result types you have two options:

If you need to customize the objects on creation, subclass TAP::Parser and override make_result.

Grammar

TAP::Parser::Grammar is the heart of the parser - it tokenizes the TAP input stream and produces results. If you need to customize its behaviour you should probably familiarize yourself with the source first. Enough lecturing.

Subclass TAP::Parser::Grammar and customize your parser by setting the grammar_class parameter. See new for more details.

If you need to customize the objects on creation, subclass TAP::Parser and override make_grammar
