NAME

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

VERSION

Version 3.17_02

SYNOPSIS

In Build.PL for your application with pgTAP tests in t/*.pg:

  Module::Build->new(
      module_name        => 'MyApp',
      test_file_exts     => [qw(.t .pg)],
      use_tap_harness    => 1,
      tap_harness_args   => {
          sources => {
              Perl  => undef,
              pgTAP => {
                  dbname => 'try',
                  username => 'postgres',
                  suffix => '.pg',
              },
          }
      },
      build_requires     => {
          'Module::Build'                      => '0.30',
          'TAP::Parser::SourceHandler::pgTAP' => '3.19',
      },
  )->create_build_script;

If you're using prove:

  prove --source Perl \
        --source pgTAP --pgtap-option dbname=try \
                       --pgtap-option username=postgres \
                       --pgtap-option suffix=.pg

Direct use:

  use TAP::Parser::Source;
  use TAP::Parser::SourceHandler::pgTAP;

  my $source = TAP::Parser::Source->new->raw(\'mytest.pg');
  $source->config({ pgTAP => {
      dbname   => 'testing',
      username => 'postgres',
      suffix   => '.pg',
  });
  $source->assemble_meta;

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

DESCRIPTION

This source handler executes pgTAP 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 pgTAP test ("can_handle").

2. Creates an iterator that will call psql to run the pgTAP tests ("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

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

Looks at the source to determine whether or not it's a pgTAP test file and returns a score for how likely it is in fact a pgTAP 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 ".pg"
  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 pgTAP tests ending in ".pg" 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 pgTAP tests are run by executing psql, the PostgreSQL command-line utility. A number of arguments are passed to it, many of which you can effect by setting up the source source configuration. The configuration must be a hash reference, and supports the following keys:

psql

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

dbname

The database to which to connect to run the tests. Defaults to the value of the $PGDATABASE environment variable or, if not set, to the system username.

username

The PostgreSQL username to use to connect to PostgreSQL. If not specified, no username will be used, in which case psql will fall back on either the $PGUSER environment variable or, if not set, the system username.

host

Specifies the host name of the machine to which to connect to the PostgreSQL server. If the value begins with a slash, it is used as the directory for the Unix-domain socket. Defaults to the value of the $PGDATABASE environment variable or, if not set, 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 value of the $PGPORT environment variable or, if not set, to the port specified at the time psql was compiled, usually 5432.
