Spring Framework - Mock is not mocking

问题

我有一个Spring MvC应用程序。（Spring Framework是Java平台的应用程序框架和控制反转容器），具有以下测试代码：

  1. @RunWith(SpringJUnit4ClassRunner.class)
  2. public class AutorisationServiceTest {
  4.     @Autowired
  5.     @InjectMocks
  6.     private IAutorisationService service;
  8.     @Mock
  9.     PersonneRepository personneRepository = Mockito.mock(PersonneRepository.class);
  11.     @Before
  12.     public void setup() {
  13.     }
  15.     @Test
  16.     public void should_Find_GardeWith2Affectations() throws IOException {
  18.         when(personneRepository.getAll(anyString())).thenReturn(DataLoader.mockData());
  19.         service.getAll("rules");
  20.     }
  21. }
  1. @Service
  2. public class AutorisationService implements IAutorisationService {
  4.     private final PersonneRepository personneRepository;
  6.     public AutorisationService(PersonneRepository personneRepository) {
  7.         this.personneRepository = personneRepository;
  8.     }
  10.     @Override
  11.     public List<User> getAll(String where) {
  12.         return personneRepository.getAll(where);
  13.     }
  14.     // ...
  15. }

但是，当我运行测试时，似乎没有对存储库进行模拟。

英文:

I have a Spring MvC app. (The Spring Framework is an application framework and inversion of control container for the Java platform) with this test:

  1.     @RunWith(SpringJUnit4ClassRunner.class)
  2.     public class AutorisationServiceTest {
  3.     
  4.     	@Autowired
  5.     	@InjectMocks
  6.     	private IAutorisationService service;
  7.     
  8.     	@Mock
  9.     	PersonneRepository personneRepository = Mockito.mock(PersonneRepository.class);
  10.     
  11.     
  12.     	@Before
  13.     	public void setup() {
  14.     	}
  15.     
  16.     
  17.     	@Test
  18.     	public void should_Find_GardeWith2Affectations() throws IOException {
  19.     
  20.     		when(personneRepository.getAll(anyString())).thenReturn(DataLoader.mockData());
  21.     		service.getAll(&quot;rules&quot;);
  22.     	}
  23.     
  24.     }
  26.     @Service
  27.     public class AutorisationService implements IAutorisationService {
  28.     
  29.     	private final PersonneRepository personneRepository;
  30.     
  31.     	public AutorisationService(PersonneRepository personneRepository) {
  32.     		this.personneRepository = personneRepository;
  33.     	}
  35. @Override
  36. 	public List&lt;User&gt; getAll(String where) {
  37. 		return personneRepository.getAll(where));
  38. 	}
  39.     ...
  40.     }

but when I run the test it seems no to mock the repo

这个回答是关于 testng 的：

MockitoTestExecutionListener 初始化模拟对象，你需要使用 @MockBean 注解。

  1. @RunWith(SpringJUnit4ClassRunner.class)
  2. @TestExecutionListeners(MockitoTestExecutionListener.class)
  3. public class AutorisationServiceTest {   
  4.     @MockBean
  5.     PersonneRepository personneRepository;

另外，别忘了添加 ResetMocksTestExecutionListener 来防止测试之间的持久模拟对象影响（参见这个问题）。

英文:

This answer is for testng:

MockitoTestExecutionListener initializes mocks, and you need to use @MockBean annotation.

  1. @RunWith(SpringJUnit4ClassRunner.class)
  2. @TestExecutionListeners(MockitoTestExecutionListener.class)
  3. public class AutorisationServiceTest {   
  4.     @MockBean
  5.     PersonneRepository personneRepository;

Also, don't forget to add ResetMocksTestExecutionListener to prevent inter-test persistent mocks (see this issue).

你应该决定是要编写一个 Spring 测试还是一个 Mockito 测试。

一个 Spring 测试会加载完整的上下文，然后您可以使用 @Autowired 和 @MockBean 进行操作：

  1. @RunWith(SpringJUnit4ClassRunner.class)
  2. public class AutorisationServiceTest {
  3.     
  4.   @Autowired
  5.   private IAutorisationService service;
  6.     
  7.   @MockBean
  8.   PersonneRepository personneRepository;

一个 Mockito 测试运行速度更快，但您只会拥有通过 @InjectMocks 或 @Mock 显式配置的对象：

  1. @RunWith(MockitoJUnitRunner.class)
  2. public class AutorisationServiceTest {
  3.   
  4.   @InjectMocks
  5.   private IAutorisationService service;
  6.     
  7.   @Mock
  8.   PersonneRepository personneRepository;

请注意，使用注解和专用运行器时，您永远不必使用 Mockito.mock() 来实例化模拟对象。

我猜您的 PersonneRepository 是一个 @Service、@Component 或 @Repository。因此在这里也应该使用自动装配：

  1. @Service
  2. public class AutorisationService implements IAutorisationService {
  4.    @Autowired    
  5.    private PersonneRepository personneRepository;
英文:

You should decide whether you want to write a Spring test or a Mockito test.

A spring test will load the full context and you can then work with @Autowired and @MockBean:

  1. @RunWith(SpringJUnit4ClassRunner.class)
  2. public class AutorisationServiceTest {
  3.     
  4.   @Autowired
  5.   private IAutorisationService service;
  6.     
  7.   @MockBean
  8.   PersonneRepository personneRepository;

A Mockito test runs much faster, but you will only have the objects you explicitly configured with @InjectMocks or @Mock:

  1. @RunWith(MockitoJUnitRunner.class)
  2. public class AutorisationServiceTest {
  3.   
  4.   @InjectMocks
  5.   private IAutorisationService service;
  6.     
  7.   @Mock
  8.   PersonneRepository personneRepository;

Note that you never have to instanciate the mock with Mockito.mock() when using annotations and specialized runners.

I guess your PersonneRepository is a @Service, @Component or @Repository. So you should use auto-wiring here as well:

  1. @Service
  2. public class AutorisationService implements IAutorisationService {
  4.    @Autowired    
  5.    private PersonneRepository personneRepository;

你不能同时使用 @Mock 和 Mockito.mock。请选择其中一个。

英文:

You can't use both @Mock and Mockito.mock. Choose one of them

在@Before的setup方法中，您需要添加MockitoAnnotations.initMocks(this)。这将注入您的模拟服务。我已经修改了下面的代码：

  1. @RunWith(SpringJUnit4ClassRunner.class)
  2. public class AutorisationServiceTest {
  4.     @Mock
  5.     PersonneRepository personneRepository;
  7.     @InjectMocks
  8.     private AutorisationService service;
  10.     @Before
  11.     public void setup() {
  12.         MockitoAnnotations.initMocks(this);
  13.     }
  15.     @Test
  16.     public void should_Find_GardeWith2Affectations() throws IOException {
  17.         when(personneRepository.getAll(anyString())).thenReturn(DataLoader.mockData());
  18.         service.getAll("rules");
  19.     }
  20. }
  22. @Service
  23. public class AutorisationService implements IAutorisationService {
  25.     private final PersonneRepository personneRepository;
  27.     public AutorisationService(PersonneRepository personneRepository) {
  28.         this.personneRepository = personneRepository;
  29.     }
  31.     @Override
  32.     public List<User> getAll(String where) {
  33.         return personneRepository.getAll(where));
  34.     }
  35.     ...
  36. }

请注意，我只翻译了您提供的代码部分。

英文:

In @Before setup method you need to add MockitoAnnotations.initMocks(this). This will inject your mocked services. I have modified the code below :

  1. @RunWith(SpringJUnit4ClassRunner.class)
  2.     public class AutorisationServiceTest {
  3.     
  4.         @Mock
  5.         PersonneRepository personneRepository;
  7.         @InjectMocks
  8.         private AutorisationService service;
  9.     
  10.         @Before
  11.         public void setup() {
  12.           MockitoAnnotations.initMocks(this);
  13.         }
  14.     
  15.     
  16.         @Test
  17.         public void should_Find_GardeWith2Affectations() throws IOException {
  18.     
  19.             when(personneRepository.getAll(anyString())).thenReturn(DataLoader.mockData());
  20.             service.getAll(&quot;rules&quot;);
  21.         }
  22.     
  23.     }
  25.     @Service
  26.     public class AutorisationService implements IAutorisationService {
  27.     
  28.         private final PersonneRepository personneRepository;
  29.     
  30.         public AutorisationService(PersonneRepository personneRepository) {
  31.             this.personneRepository = personneRepository;
  32.         }
  34. @Override
  35.     public List&lt;User&gt; getAll(String where) {
  36.         return personneRepository.getAll(where));
  37.     }
  38.     ...
  39.     }
