运行嘲笑测试时无法模仿功能

Question

我正在使用Mockmvc编写控制器的测试用例

@Mock
private AService aService;

@InjectMocks
private AController aController;



@BeforeEach
    public void init() {
        MockitoAnnotations.initMocks(this);
        mockMvc = MockMvcBuilders
                .standaloneSetup(aController)
                .setCustomArgumentResolvers(putAuthenticationPrincipal)  // for passing the authentication principal
                .build();
    }

现在当我尝试测试

@Test
    public void testfunction() throws Exception {
        String id = UUID.randomUUID().toString();
  Mockito.when(aService.getAccount(Mockito.anyString())).thenThrow(new Exception("not avalible"));
        mockMvc.perform(MockMvcRequestBuilders.get("/account/{id}", id)
....      
   }

在这种情况下，aService.getAccount（）不会被模拟。这就是为什么我没有得到理想的结果。

我不明白为什么在这种情况下无法模拟功能。

要这样做：

• 用@WebMvcTest注释测试类
• 使用@WebMvcTest(YourController.class)而非@MockBean注释协作服务
