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？

Question

我正在尝试对我的捆绑进行单元测试,我想从EventManager Mock中获取工作单元.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执行相同的操作.

基本上我想要实现的是,如果其标志处于挂起状态,则检查先前持久记录的状态,然后在下一个持久化中,我想将其更新为未挂起.

例:

以下是我获得活动管理器的方法:

/**
 * @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);
}

仍然收到错误:

尝试添加另一个预期的方法来使用该函数，如下所示：

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

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