I have a PHPUnit test that’s using a Doctrine2 custom repository and Doctrine Fixtures. I wanted to test that a query gave me back an expected entity from my fixture.
But when I try $this->assertEquals($expectedEntity, $result);, I get Fatal error: out of memory. I’m guessing it is recursing into all the relations and the entity manager and whatnot.
Is there a good way to test this equality? Should I just assertEquals on the IDs of the entities?
Edit:
Here is the test code
<?php
use Liip\FunctionalTestBundle\Test\WebTestCase;
class AbstractRepositoryTestCase extends WebTestCase
{
/**
* @var Doctrine\ORM\EntityRepository
*/
protected $repo;
/**
* @var Doctrine\Common\DataFixtures\Executor\AbstractExecutor
*/
protected $fixtureExecutor;
/**
* @var string Which repository to load, overriden by derived class
*/
protected $repoName;
/**
* @var array Fixture classes to load on setup
*/
protected $fixtures = array();
public function setUp()
{
$kernel = static::createKernel();
$this->repo = $kernel->boot();
$this->repo = $kernel->getContainer()
->get('doctrine.orm.entity_manager')
->getRepository($this->repoName);
$this->fixtureExecutor = $this->loadFixtures($this->getFixtures());
}
public function getFixtures()
{
return $this->fixtures;
}
}
class ArticleRepositoryTest extends AbstractRepositoryTestCase
{
/**
* @var string Which repository to load, overriden by derived class
*/
protected $repoName = 'MyMainBundle:Article';
/**
* @var array Fixture classes to load on setup
*/
protected $fixtures = array(
'My\MainBundle\DataFixtures\ORM\LoadUserData',
'My\MainBundle\DataFixtures\ORM\LoadArticleData',
'My\MainBundle\DataFixtures\ORM\LoadFeedsData',
'My\MainBundle\DataFixtures\ORM\LoadFeedDataData',
'My\MainBundle\DataFixtures\ORM\LoadUserReadArticleData',
);
public function testGetNextArticle_ExpectCorrect()
{
/** @var Doctrine\Common\DataFixtures\ReferenceRepository **/
$refRepo = $this->fixtureExecutor->getReferenceRepository();
/** @var FeedStream\MainBundle\Entity\Article **/
$curr = $refRepo->getReference('feed-1-article-3');
$expected = $refRepo->getReference('feed-1-article-2');
$expected2 = $refRepo->getReference('feed-1-article-1');
$next = $this->repo->getNextArticle($curr->getFeed()->getId(), $curr);
$this->assertNotNull($next);
// this is the part that doesn't work
$this->assertEquals($expected, $next);
// this is the code I've used instead
$this->assertEquals($expected->getId(), $next->getId());
}
}
Here is the entity (getters/setters omitted to save space)

You should also test the class in addition to the ID.
