如何从EventManager Mock对象获取UnitOfWork或者如何获取PHP单元中的最后一个持久对象？

Question

我想单元测试我的包，我想从EventManager模拟获得工作单元。基本上，我想获得最后一个持久对象。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。

我想要实现的基本上是检查以前持久记录的状态，如果它的标志挂起，那么在下一次持续时，我想将其更新为未挂起。

例子：

下面是如何得到事件管理器：

/** 
* @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; 
} 

而且在我的测试：

/** 
* 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); 
}

仍然会收到错误：

Answer 1

尝试添加另一种预期的方法来使用该函数是这样的：

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

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

Answer 2

我想你想检查持久实体具有设定的某个特定值，当然是正确的类型。一旦你拥有了它容易

如果坚持（）只叫：

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

凭借更先进的期望：

你应该这样添加此到persist方法的实体管理器

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

如果不坚持（），你必须使用$这 - >在（测试代码的唯一调用），而不是一次（）：

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