NAME

DBIx::Class::EasyFixture - Easy-to-use DBIx::Class fixtures.

VERSION

Version 0.01

SYNOPSIS

    package My::Fixtures;
    use Moose;
    extends 'DBIx::Class::EasyFixture';

    sub get_fixture       { ... }
    sub all_fixture_names { ... }

And in your test code:

    my $fixtures = My::Fixtures->new( { schema => $schema } );
    $fixtures->load('some_fixture');

    # run your tests

    $fixtures->unload;

Note that unload will be called for you if your fixture object falls out of scope.

DESCRIPTION

This is ALPHA code. Documentation is on its way, including a tutorial. For now, you'll have to read the tests. You can read t/lib/My/Fixtures.pm to see how fixtures are defined.

I wanted an easier way to load fixtures for DBIx::Class code. I looked at DBIx::Class::Fixtures and it made a lot of assumptions that, while appropriate for some, is not what I wanted (such as the necessity of storing fixtures in JSON files), and had a reliance on knowing the values of primary keys, I wrote this to make it easier to define and load DBIx::Class fixtures for tests.

METHODS

new

    my $fixtures = Subclass::Of::DBIx::Class::EasyFixture->new({
        schema => $dbix_class_schema_instance,
    });

This creates and returns a new instance of your DBIx::Class::EasyFixture subclass.

all_fixture_names

    my @fixture_names = $fixtures->all_fixture_names;

Must overridden in your subclass. Should return a list (not an array ref!) of all fixture names available. This is used internally to generate error messages if a fixture attempts to reference a non-existent fixture in its next or requires section.

get_definition

    my $definition = $fixtures->get_definition($fixture_name);

Must be overridden in a subclass. Should return the fixture definition for the fixture name passed in. Should return undef if the fixture is not found.

get_result

    my $dbic_result_object = $fixtures->get_result($fixture_name);

Returns the DBIx::Class::Result object for the given fixture name. Will carp if the fixture wasn't loaded (this may become a fatal error in future versions).

load

    $fixtures->load(@list_of_fixture_names);

Attempts to load all fixtures passed to it. If a transaction has not already been started, it will be started now. This method may be called multiple times.

unload

    $fixtures->unload;

Rolls back the transaction started with load

fixture_loaded

    if ( $fixtures->fixture_loaded($fixture_name) ) {
        ...
    }

Returns a boolean value indicating whether or not the given fixture was loaded.

TODO

  • Prevent circular fixtures

    Currently it's very easy to define circular dependencies. We'll worry about that later when it becomes more clear how to best handle them.

  • Better load information

    Track what fixtures are requested and what fixtures are loaded (and in which order). This makes for better error reporting.
