@WebMvcTest fails with java.lang.IllegalStateException: Failed to load ApplicationContext

Question

I'm having trouble getting my tests annotated with @WebMvcTest to work. I have also configured spring-cloud-config-server and spring-cloud-starter, and all Test classes with this annotation seem to fail. I have the following controller test:

Code:

@RunWith(SpringRunner.class)
@WebMvcTest(controllers = UserController.class)
@ActiveProfiles({"dev", "native"})
public class UserControllerTest {

    @MockBean
    private UserService userService;
    @Autowired
    private MockMvc mockMvc;
    @Autowired
    private ObjectMapper objectMapper;

    @Test
    public void changePassword() throws Exception {
        given(userService.changePassword(any(), any(), any())).willReturn(true);
        MvcResult result = mockMvc.perform(post(/user/changePassword)
                .param("old", "Pa$$W0rd")
                .param("new, "NewPa$$W0rd"))
                .andExpect(status().isOk()).andReturn();
        assertThat(result).isNotNull();
    assertThat(result.getResponse().getContentAsString()).isEqualTo("true");
    }
}

The relevant controller:

@RestController
@RequestMapping(/user)
@Log4j2
public class UserController {

    private UserService userService;

    public UserController(UserService userService) {
        this.userService = userService;
    }

    @Timed
    @PostMapping(value = /changePassword)
    public ResponseEntity changePassword(@RequestParam("old") String oldPassword,
                                         @RequestParam("new") String newPassword) throws Exception {
        String username = SecurityUtil.getCurrentLogin();
        Boolean result = userService.changePassword(username, oldPassword, newPassword);
        return new ResponseEntity<>(result, HttpStatus.OK);
    }
}

It is worth mentioning that as a result of my spring-cloud configurations I also had to update the META-INF/spring.factories file and update my main ServerApplication class with the following annotations:

@Configuration
@EnableAutoConfiguration
@SpringBootConfiguration
@ComponentScan(excludeFilters = {@ComponentScan.Filter(type= FilterType.ASSIGNABLE_TYPE, value=AppPropertiesConfiguration.class)})
@ServletComponentScan
@EnableConfigServer
@EnableRetry
@Log4j2
public class ServerApplication {
...
...
}

After running my tests I get the following error:

Conclusion: After a lot of searching I came to the conclusion that it probably has to be something with the fact that @WebMvcTest has problems with classes configured as @Configuration or @EnableConfig server but everything I have tried hasn't helped me solve this issue.

Answer 1

I could only solve it by using @AutoConfigureMockMvc in combination with @SpringBootTest instead of @WebMvcTest

   @RunWith(SpringRunner.class)
   @ComponentScan(basePackages = {"com.mypackage"})
   @SpringBootTest
   @AutoConfigureMockMvc
   public class MyClass{}

Somehow every other combination with @WebMvcTest I´ve tried did result in the same error

Answer 2

I found the reason I was having this problem. From spring docs @SpringBootApplication:

Indicates a configuration class that declares one or more @Bean methods and also triggers auto-configuration and component scanning. This is a convenience annotation that is equivalent to declaring @Configuration, @EnableAutoConfiguration and @ComponentScan.

However, this is the full declaration of the @SpringBootApplication annotation:

@Target(value=TYPE)
@Retention(value=RUNTIME)
@Documented
@Inherited
@SpringBootConfiguration
@EnableAutoConfiguration
@ComponentScan(excludeFilters={@ComponentScan.Filter(type=CUSTOM,classes=TypeExcludeFilter.class),})
public @interface SpringBootApplication

When I added the @ComponentScan annotation directly in my application class I did not specify the default excludedFilters and that is why the behavior was different. After adding the excludeFilter I was able to solve my issue.

Answer 3

Solution that worked for me. After the @WebMvcTestannotation, you need to add the name of the class under test in brackets. For example: @WebMvcTest(FacultyController.class)

@WebMvcTest(FacultyController.class)
class FacultyControllerTests {

@Autowired
private MockMvc mockMvc;
@MockBean
private FacultyRepository facultyRepository;

@SpyBean
private FacultyService facultyService;

@InjectMocks
private FacultyController facultyController;

@Test
void testFaculty() throws Exception {
}

}

Answer 4

How to solve

Just need to put all of the classes you missed in @WebMvcTest.

example

For example, an error msg said "'UserDao' that could not be found". You just need to put UserDao.class in @WebMvcTest. eg. @WebMvcTest({the class you want to test.class, UserDao.class})

another method

Of course, you can also use @ComponentScan to scan all of the classes that you need as well.

Answer 5

@SpringBootTest(classes = {ClassToTest.class})
@ExtendWith(SpringExtension.class)
@AutoConfigureMockMvc

Combination of these annotations worked for me.

I was facing this same issue while controller mock mvc testing in spring boot, JUnit5, Mockito.
