README
This plugin provide fixtures managment. Should work with any kind of Source
adapters. The fixture class support the following datasource's hints:
-
If
Source::enabled('schema')
returnstrue
, theFixture
manage schema (i.e create/drop) viaSource::createSchema()
&Source::dropSchema()
. -
If
Source::enabled('sources')
returnstrue
, theFixture
allow soft drop (i.e safe options).
Installation
The preferred installation method is via composer. You can add the library as a dependency via:
composer require unionofrad/li3_fixtures
li₃ plugins must be registered within your application bootstrap phase as they use a different (faster) autoloader.
Libraries::add('li3_fixtures')
The official manual has more information on how to register the plugin with the app or use alternative installation methods (i.e. via GIT).
API
The Fixture class
Methods:
- Fixture::create($safe); //Create the source only
- Fixture::save($safe); //Create the source + save the fixture's records in.
- Fixture::drop($safe); //Drop the source.
- Fixture::populate($records); //Insert a record in the database
- Fixture::alter($mode, $fieldname, $value); //Altering the schema before
::create()/::save()
.
Simple example of unit test:
<?php //app/tests/cases/models/SampleTest.php namespace app\tests\cases\models; use li3_fixtures\test\Fixture; class SampleTest extends \lithium\test\Unit { public function testFixture() { $fixture = new Fixture([ 'connection' => 'lithium_mysql_test', 'source' => 'contacts', 'fields' => array( 'id' => array('type' => 'id'), 'name' => array('type' => 'string') ), 'records' => array( array('id' => 1, 'name' => 'Nate'), array('id' => 2, 'name' => 'Gwoo') ) ]); $fixture->save(); $fixture->populate(['id' => 3, 'name' => 'Mehlah']); $fixture->drop(); } } ?>
The Fixtures class
Fixture
is a kind of Schema
which contain records and a source name or a reference to a model.
So let save the above fixture in a class.
<?php //app/tests/fixture/ContactsFixture.php namespace app\tests\fixture; class ContactsFixture extends \li3_fixtures\test\Fixture { protected $_model = 'app\models\Contacts'; protected $_fields = array( 'id' => ['type' => 'id'], 'name' => ['type' => 'string'] ); protected $_records = [ array['id' => 1, 'name' => 'Nate'], array['id' => 2, 'name' => 'Gwoo'] ]; } ?>
<?php //app/models/Contact.php namespace app\models; class Contacts extends \lithium\data\Model {} ?>
If you have numbers of fixtures, it will be interesting to use the Fixtures
class.
Example of use case:
<?php //app/tests/integration/Sample2Test.php namespace app\tests\integration; use li3_fixtures\test\Fixtures; use app\models\Contacts; use app\models\Images; // and so on... class Sample2Test extends \lithium\test\Unit { public function setUp() { Fixtures::config([ 'db' => [ 'adapter' => 'Connection', 'connection' => 'lithium_mysql_test', 'fixtures' => array( 'contacts' => 'app\tests\fixture\ContactsFixture', 'images' => 'app\tests\fixture\ImagesFixture' // and so on... ) ] ]); Fixtures::save('db'); } public function tearDown() { Fixtures::clear('db'); } public function testFixture() { var_export(Contacts::find('all')->data()); var_export(Images::find('all')->data()); } } ?>
Ok so why it's better to set the Fixture::_model
instead of Fixture::_source
? Long story short,
models had their own meta 'connection'
value. If a fixture is "linked" with a model, it will
automagically configure its meta 'connection'
to the fixture's connection when is created or saved.
Example:
<?php Fixtures::save('db', array('contacts')); //The line bellow is not needed since Contacts have been configured by ContactsFixture. Contacts::config(['meta' => ['connection' => 'lithium_mysql_test']]); var_export(Contacts::find('all')->data()); ?>
Advanced use case
For interoperability, sometimes it's usefull to adjust fixtures according a datasources.
You can alter Fixture
's instance before creating it like the following use case:
<?php $fixture->alter('add', [ 'name' => 'enabled', 'type' => 'boolean' ]); //Add a field $fixture->alter('change', [ 'name' => 'published', 'value' => function ($val) { return new MongoDate(strtotime($val)); } ]); //Simple cast for fixture's values according the closure $fixture->alter('change', [ 'name' => 'id', 'to' => '_id', 'value' => function ($val) { return new MongoId('4c3628558ead0e594' . (string) ($val + 1000000)); } ]); //Renaming the field 'id' to '_id' + cast fixture's values according the closure $fixture->alter('change', [ 'name' => 'bigintger', 'type' => 'integer', 'use' => 'bigint' //use db specific type ]); //Modifing a field type $fixture->alter('drop', 'bigintger'); //Simply dropping a field ?>
Note :
You can recover a specific fixture's instance from Fixtures
using:
<?php $fixture = Fixtures::get('db', 'contacts'); ?>
