为什么工厂在测试表单中为空？

Question

我想测试我的形成延伸TypeTestCase类

class ProjectTypeTest extends TypeTestCase 
{ 

    private $entityManager; 
    private $securityContext; 
    private $translator; 
    private $formFactory; 

    protected function setUp() 
    { 
     // mock any dependencies 
     $this->entityManager = $this->createMock("Doctrine\ORM\EntityManagerInterface"); 
     $this->securityContext = $this->createMock("Symfony\Component\Security\Core\SecurityContextInterface"); 
     $this->translator = $this->createMock("Symfony\Component\Translation\TranslatorInterface"); 
     $this->formFactory = $this->createMock("AppBundle\FormTemplate\Factory\FormFactory"); 

    }  

    public function testSubmitValidData() 
    { 

     $type = new ProjectType($this->entityManager,$this->securityContext, $this->translator, $this->formFactory); 


     $this->factory->create($type); 

    } 

} 

但是，当我打电话$this->factory->create($type)，返回：

调用一个成员函数上的空创建（）

factory属性为空！

我使用的是Symfony\Component\Form\Test\TypeTestCase，我也使用了use Symfony\Component\Form\Tests\Extension\Core\Type\TypeTestCase，并返回相同的结果。或者，我做的不好？ 或者，我如何测试表格？

问题是$this->factory未被初始化。这应该由FormIntegrationTestCase完成，它由TypeTestCase，然后由您的测试类扩展。

你setUp()是覆盖原来的setUp()，初始化$this->factory，所以你应该调用父类之一：

protected function setUp() 
{ 
    parent::setUp(); 

    // mock any dependencies 
    $this->entityManager = $this->createMock("Doctrine\ORM\EntityManagerInterface"); 
    $this->securityContext = $this->createMock("Symfony\Component\Security\Core\SecurityContextInterface"); 
    $this->translator = $this->createMock("Symfony\Component\Translation\TranslatorInterface"); 
    $this->formFactory = $this->createMock("AppBundle\FormTemplate\Factory\FormFactory"); 

}
