Question

我有一个使用Doctrine2自定义存储库和Doctrine Fixtures的PHPUnit测试。我想测试一个查询让我从夹具中找回了一个预期的实体。

但是当我尝试$this->assertEquals($expectedEntity, $result);时，我得到Fatal error: out of memory。我猜它正在递归到所有关系和实体管理器等等。

有没有一种好方法来测试这种平等？我应该只断言实体的ID吗？

修改这是测试代码

<?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());
    }
}

这是实体（省略了getters / setters以节省空间）

Answer 1

如果实体是等于的，assertEquals可以与Doctrine实体一起使用。

当对象不相同时会发生问题，然后phpunit会根据你的图表探索entites图并且永远不会结束。不幸的是，maxDepth的{{1}}参数似乎没有像预期的那样限制递归，所以我担心解决方案是：

assertEquals需要保留实体，并在发生故障时提供不匹配对象的标识符
$this->assertEquals($entity1->getId(), $entity2->getId())或$this->assertEquals(spl_object_hash($entity1), spl_object_hash($entity2))两者都完美有效，但他们并未向您提供有关差异的详细信息
最佳解决方案恕我直言：将实体转换为具有类名称和数组比较属性的数组：

使用Doctrine \ Common \ Util \ Debug; $ this-＆gt; assertEquals（Debug :: export（$ entity1），Debug :: export（$ entity2））;

这会给你一个明确的错误，说明什么属性是不同的（在这种情况下，甚至班级也不同）

$this->assertTrue($entity1 === $entity2)

（您可以将此比较放入Failed asserting that two objects are equal. --- Expected +++ Actual @@ @@ stdClass Object ( - '__CLASS__' => 'Service\Entity\RoleLN' - 'id' => 'ln_admin' - 'isApprover' => false - 'rate' => null - 'name' => 'ln_admin' - 'roles' => null - 'processTasks' => null + '__CLASS__' => 'Service\Entity\Role' + 'id' => 99 + 'rate' => 400 + 'name' => 'roleAdmin' + 'roleLN' => stdClass Object (...) + 'organisation' => stdClass Object (...) + 'users' => null + 'matterRoles' => Array ()）

之类的方法中

Answer 2

除了ID之外，您还应该测试该类。

使用assertEquals测试Doctrine2实体会导致致命的内存不足错误
