TAP::Parser::SourceHandler::Executable

NAME

TAP::Parser::SourceHandler::Executable - Stream output from an executable TAP source

VERSION

Version 3.30

SYNOPSIS

  1. use TAP::Parser::Source;
  2. use TAP::Parser::SourceHandler::Executable;
  3. my $source = TAP::Parser::Source->new->raw(['/usr/bin/ruby', 'mytest.rb']);
  4. $source->assemble_meta;
  5. my $class = 'TAP::Parser::SourceHandler::Executable';
  6. my $vote = $class->can_handle( $source );
  7. my $iter = $class->make_iterator( $source );

DESCRIPTION

This is an executable TAP::Parser::SourceHandler - it has 2 jobs:

1. Figure out if the TAP::Parser::Source it's given is an executable command (can_handle).

2. Creates an iterator for executable commands (make_iterator).

Unless you're writing a plugin or subclassing TAP::Parser, you probably won't need to use this module directly.

METHODS

Class Methods

can_handle

  1. my $vote = $class->can_handle( $source );

Only votes if $source looks like an executable file. Casts the following votes:

  1. 0.9 if it's a hash with an 'exec' key
  2. 0.8 if it's a .bat file
  3. 0.75 if it's got an execute bit set

make_iterator

  1. my $iterator = $class->make_iterator( $source );

Returns a new TAP::Parser::Iterator::Process for the source. $source->raw must be in one of the following forms:

  1. { exec => [ @exec ] }
  2. [ @exec ]
  3. $file

croak s on error.

iterator_class

The class of iterator to use, override if you're sub-classing. Defaults to TAP::Parser::Iterator::Process.

SUBCLASSING

Please see SUBCLASSING in TAP::Parser for a subclassing overview.

Example

  1. package MyRubySourceHandler;
  2. use strict;
  3. use Carp qw( croak );
  4. use TAP::Parser::SourceHandler::Executable;
  5. use base 'TAP::Parser::SourceHandler::Executable';
  6. # expect $handler->(['mytest.rb', 'cmdline', 'args']);
  7. sub make_iterator {
  8. my ($self, $source) = @_;
  9. my @test_args = @{ $source->test_args };
  10. my $rb_file = $test_args[0];
  11. croak("error: Ruby file '$rb_file' not found!") unless (-f $rb_file);
  12. return $self->SUPER::raw_source(['/usr/bin/ruby', @test_args]);
  13. }
