使用 Mockito 测试时为空控制器

Question

我正在测试需要自动连接服务的控制器。

我看了很多地方（例如Mockito: How to test my Service with mocking?）我需要这样做

@RunWith(JUnitPlatform.class)
public class AdminControllerTest {

  @Mock
  private AdminService service;

  @InjectMocks
  private AdminController adminController;

  @Test
  public void registerUser() {
    Boolean resultReal = adminController.registerUser();
    assertTrue(resultReal);
  }
}

但它失败了，我看到是因为 adminController 为空

相反，如果我像这样创建控制器

AdminController adminController = new AdminController();

它有效，但我可以注入模拟。

也许我忘记了什么

Answer 1

根据 the documentation for InjectMocks:

MockitoAnnotations.openMocks(this) method has to be called to initialize annotated objects. In above example, openMocks() is called in @Before (JUnit4) method of test's base class. For JUnit3 openMocks() can go to setup() method of a base class. Instead you can also put openMocks() in your JUnit runner (@RunWith) or use the built-in MockitoJUnitRunner.

因此，要么：

在测试运行或

openMocks(this)

在 class

@RunWith(MockitoJUnitRunner.class)

使用 Mockito 测试时为空控制器

Null controller when test with Mockito
