Question

我正在尝试对我的捆绑包进行单元测试，我想从EventManager Mock获取工作单元。基本上，我想获得最后一个持久化对象。我知道在正常的应用程序中，我可以使用EventSubscriber。

我想要实现的基本上，如果其标志处于待处理状态，请检查上一个持久记录的状态，然后在下一个持久化中，我想将其更新为未挂起。

示例：

以下是我获取活动管理器的方法：

/**
 * @param Entity\Friend|null $friendEntity
 * @return \Doctrine\ORM\EntityManager|\PHPUnit_Framework_MockObject_MockObject
 */
private function getEntityManager(Entity\Friend $friendEntity = null)
{
    $repository = $this
        ->getMockBuilder('\Doctrine\ORM\EntityRepository')
        ->disableOriginalConstructor()
        ->setMethods(['findBy'])
        ->getMock();
    $repository
        ->expects($this->any())
        ->method('findBy')
        ->will($this->returnValue(null));

    /** @var \Doctrine\ORM\EntityManager|\PHPUnit_Framework_MockObject_MockObject $entityManager */
    $entityManager = $this
        ->getMockBuilder('\Doctrine\ORM\EntityManager')
        ->setMethods(['getRepository', 'getUnitOfWork', 'persist'])
        ->disableOriginalConstructor()
        ->getMock();
    $entityManager
        ->expects($this->any())
        ->method('getRepository')
        ->will($this->returnValue($repository));
    $entityManager
        ->expects($this->any())
        ->method('getUnitOfWork')
        ->will($this->returnValue($repository));
    $entityManager
        ->expects($this->any())
        ->method('persist')
        ->with($friendEntity)
        ->will($this->returnValue(null));
    return $entityManager;
}

在我的测试中：

/**
 * Test add friend when friend pending
 */
public function testAddFriendPending()
{
    $friendEntity = new Entity\Friend($this->friend, $this->user);
    $entityManager = $this->getEntityManager($friendEntity);
    $pendingRequest = new FriendService($entityManager);
    /** @var Entity\Friend $lastInsert */
    $lastInsert = $pendingRequest->addFriend($this->friend, $this->user);
    $lastInsert->setId(1);
    $friendAddRequest = new FriendService($entityManager);
    $friendAddRequest->addFriend($this->user, $this->friend);
    $response = $friendAddRequest->getStatus();
    $this->assertEquals(Entity\Friend::FRIEND_ADD_STATUS_COMPLETED, $response);
}

修改

仍然收到错误：

Answer 1

我想您要检查持久化实体是否设置了一些特定值，当然是正确的类型。

您应该将此添加到实体管理器的persist方法中，如下所示：

如果只是轻松地调用persist（）：

$entityManager
    ->expects($this->once())
    ->method('persist')
    ->with($theEntityYouExpectWithAllValues)
    ->will($this->returnValue(null));

有更复杂的期望：

$entityManager
    ->expects($this->once())
    ->method('persist')
    ->willReturnCallback(function($entityToTest){
        $this->assertInstanceOf(EntityClass::class, $entityToTest);
        $this->assertEquals('some_value', $entityToTest->someKey);
    });

如果它不是对测试代码中唯一的persist（）调用，则必须使用$ this-＆gt; at（）而不是once（）：

$entityManager
    ->expects($this->at(3)) // 3rd call of any method on manager not just persist
    ->method('persist')
    // ...

尝试添加另一个预期的方法来使用这个函数：

    $configurationMock = $this
        ->getMockBuilder('\Doctrine\ORM\Mapping\EntityListenerResolver')
        ->disableOriginalConstructor()
        ->getMock();

    $entityManager
        ->expects($this->any())
        ->method('getConfiguration')
        ->will($this->returnValue($configurationMock));

如何从EventManager Mock对象获取UnitOfWork或者如何在PHP单元中获取最后一个持久化对象？
