使用Mockito和MockMvc的方法中的缺少代码属性

Question

public class ExampleRestControllerTest {

     private MockMvc mockMvc;

     @Mock
     private MyService myService;

     @InjectMocks
     private MyRestController myRestController;

     @Before
     public void setUp() {
        MockitoAnnotations.initMocks(this);
        StandaloneMockMvcBuilder setup =    MockMvcBuilders.standaloneSetup(myService);
        mockMvc = setup.build();
}

When MockMvcBuilders.standaloneSetup(myService); is executed I have returned this stack trace:

What may be wrong?

Thanks

standaloneSetup() takes your controller. Maybe the following example can help you:

@RunWith(MockitoJUnitRunner.class)
public class IndexControllerTest {

    private IndexController classUnderTest;

    @Mock
    private IndexService mockedService;

    @Before
    public void setUp() {
        classUnderTest = new IndexController(mockedService);
    }

    @Test
    public void testMockMvc() throws Exception{
        MockMvc mockMvc = MockMvcBuilders.standaloneSetup(classUnderTest).build();

        mockMvc.perform(get("/")).andExpect(status().isOk()).andExpect(view().name("index"));

    }
}
