Junit 5 doesn't see controllers URL when using @WebMvcTest - Mockito and Spring Boot

Question

I created a test class for SystemAuthorityController, as i only need part of the context to be loaded.

I've used @WebMvcTest annotation and I`ve specified which controller I want to test (I also tried with all controllers but that didn't work either).

@WebMvcTest(SystemAuthorityController.class)
@TestPropertySource("classpath:application.properties")
public class SystemAuthorityControllerTest

When I try to call any endpoint from this controller I get 404, because the endpoint wasn't found.

After some research I found the solution - that is to add @Import annotation with the controller which I need and everything worked after that, the URL was found.

@WebMvcTest(SystemAuthorityController.class)
@Import({SystemAuthorityController.class})
@TestPropertySource("classpath:application.properties")
public class SystemAuthorityControllerTest

My question here is why I need to explicitly import the controller I want to test as I never seen this annotation being used for this purpose (neither do I think that I should be used like this). From my understanding WebMvcTest should load all controller beans.

There is no need to explicitly import controller if working in same module.

If you are getting 404, it's probably due to some other reason. [Need to see logs]

This is the basic working example of ControllerTest. [In case you miss anything]

@RunWith(MockitoJUnitRunner.class)
@AutoConfigureMockMvc
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class AControllerTest {
    
    @InjectMocks
    AController aController;
    
    @Autowired
    MockMvc mockMvc;
    
    @Mock
    AService aService;
        
    @Before
    public void setUp() {
        this.mockMvc = MockMvcBuilders.standaloneSetup(aController).build();

    }
    
    @Test
    public void aTest() throws Exception {
        ObjectMapper objectMapper = new ObjectMapper();
        ADetails user = new ADetails();
        user.setId("1234");
        this.mockMvc.perform(MockMvcRequestBuilders.post("/a/signin").header("Referer", "test")
                                                   .contentType(MediaType.APPLICATION_JSON)
                                                   .content(objectMapper.writeValueAsString(user)))
                    .andExpect(MockMvcResultMatchers.status().is2xxSuccessful());
    }
