TAP::Parser::SourceHandler::MyTAP - Stream TAP from MyTAP test scripts

Synopsis

In Build.PL for your application with MyTAP tests in t/*.my:

  Module::Build->new(
      module_name        => 'MyApp',
      test_file_exts     => [qw(.t .my)],
      use_tap_harness    => 1,
      tap_harness_args   => {
          sources => {
              Perl  => undef,
              MyTAP => {
                  database => 'try',
                  user     => 'root',
                  suffix   => '.my',
              },
          }
      },
      build_requires     => {
          'Module::Build'                     => '0.30',
          'TAP::Parser::SourceHandler::MyTAP' => '3.22',
      },
  )->create_build_script;

If you're using prove:

  prove --source Perl \
        --ext .t --ext .my \
        --source MyTAP --mytap-option database=try \
                       --mytap-option user=root \
                       --mytap-option suffix=.my

If you have only MyTAP tests, just use my_prove:

  my_prove --database try --user root

Direct use:

  use TAP::Parser::Source;
  use TAP::Parser::SourceHandler::MyTAP;

  my $source = TAP::Parser::Source->new->raw(\'mytest.my');
  $source->config({ MyTAP => {
      database => 'testing',
      user     => 'root',
      suffix   => '.my',
  }});
  $source->assemble_meta;

  my $class = 'TAP::Parser::SourceHandler::MyTAP';
  my $vote  = $class->can_handle( $source );
  my $iter  = $class->make_iterator( $source );

Description

This source handler executes MyTAP MySQL tests. It does two things:

  1. Looks at the TAP::Parser::Source passed to it to determine whether or not the source in question is in fact a MyTAP test ("can_handle").

  2. Creates an iterator that will call mysql to run the MyTAP tests ("make_iterator").

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

Testing with MyTAP

If you just want to write tests with MyTAP, here's how:

  • Download MyTAP and install it into your MySQL server:

      mysql -u root < mytap.sql
  • Write your tests in files ending in .my in the t directory, right alongside your normal Perl .t tests. Here's a simple MyTAP test to get you started:

      BEGIN;
    
      SELECT tap.plan(1);
    
      SELECT tap.pass('This should pass!');
    
      CALL tap.finish();
      ROLLBACK;

    Note how the MyTAP functions are being called from the tap database.

  • Run your tests with my_prove like so:

      my_prove --database try --user root t/

    Or, if you have Perl .t and MyTAP .my tests, run them all together with prove:

            --ext .t --ext .my \
            --source MyTAP --mytap-option database=try \
                           --mytap-option user=root \
                           --mytap-option suffix=.my
    =item *

    Once you're sure that you've got the MyTAP tests working, modify your Build.PL script to allow ./Build test to run both the Perl and the MyTAP tests, like so:

      Module::Build->new(
          module_name        => 'MyApp',
          test_file_exts     => [qw(.t .my)],
          use_tap_harness    => 1,
          configure_requires => { 'Module::Build' => '0.30', },
          tap_harness_args   => {
              sources => {
                  Perl  => undef,
                  MyTAP => {
                      database => 'try',
                      user     => 'root',
                      suffix   => '.my',
                  },
              }
          },
          build_requires     => {
              'Module::Build'                     => '0.30',
              'TAP::Parser::SourceHandler::MyTAP' => '3.22',
          },
      )->create_build_script;

    The use_tap_harness parameter is optional, since it's implicitly set by the use of the tap_harness_args parameter. All the other parameters are required as you see here. See the documentation for make_iterator() for a complete list of options to the MyTAP key under sources.

    And that's it. Now get testing!

Methods

Class Methods

can_handle

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

Looks at the source to determine whether or not it's a MyTAP test file and returns a score for how likely it is in fact a MyTAP test file. The scores are as follows:

  1    if it has a suffix equal to that in the "suffix" config
  1    if its suffix is ".my"
  0.8  if its suffix is ".sql"
  0.75 if its suffix is ".s"

The latter two scores are subject to change, so try to name your MyTAP tests ending in ".my" or specify a suffix in the configuration to be sure.

make_iterator

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

Returns a new TAP::Parser::Iterator::Process for the source. $source->raw must be either a file name or a scalar reference to the file name.

The MyTAP tests are run by executing mysql, the MySQL command-line utility. A number of arguments are passed to it, many of which you can affect by setting up the source source configuration. The configuration must be a hash reference, and supports the following keys:

mysql

The path to the mysql command. Defaults to simply "mysql", which should work well enough if it's in your path.

database

The database to which to connect to run the tests. Defaults to the system username.

user

The MySQL user to use to connect to MySQL. If not specified, no user will be used, in which case mysql will fall back on the system username.

password

The password to use to connect to MySQL. If not specified, no password will be used.

host

Specifies the host name of the machine to which to connect to the MySQL server. Defaults to the local host.

port

Specifies the TCP port or the local Unix-domain socket file extension on which the server is listening for connections. Defaults to the port specified at the time mysql was compiled, usually 3306.
