Error when using @WebMvcTest annotation on a Spring Boot test class

Question

I've written a test class for a Spring MVC controller by following the "Testing the Spring MVC slice" section described here. The class looks like this:

@RunWith(SpringRunner.class)
@WebMvcTest(controllers=OurController.class)
public class OurControllerTest {
    @Autowired
    private MockMvc mvc;

    @MockBean
    private OurRepository ourRepository;

    @Test
    public void testGetStuff() {
        // code removed
    }
}

When I ran it, I got the following error:

MockHttpServletResponse:
           Status = 401
    Error message = null
          Headers = {Cache-Control=[no-store], Pragma=[no-cache], WWW-Authenticate=[Bearer realm="oauth2-resource", error="unauthorized", error_description="Full authentication is required to access this resource"], Content-Type=[application/json;charset=UTF-8], X-Content-Type-Options=[nosniff], X-XSS-Protection=[1; mode=block], X-Frame-Options=[DENY]}
     Content type = application/json;charset=UTF-8
             Body = {"error":"unauthorized","error_description":"Full authentication is required to access this resource"}
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

java.lang.AssertionError: Status 
Expected :200
Actual   :401

[rest of stack trace removed]

The "Full authentication is required to access this resource" error is mentioned here, and it suggests a couple workarounds. I tried changing the annotations on my test class to the following:

@RunWith(SpringRunner.class)
@WebMvcTest(controllers=OurController.class, includeFilters = @ComponentScan.Filter(classes=EnableWebSecurity.class))

Then I got the following error:

2016-12-19 15:43:59.218 ERROR 91076 --- [           main] c.o.m.u.c.error.ErrorHandlerController   : Access is denied

Then I found another page that suggested using the @AutoConfigureMockMvc annotation to solve the "Full authentication is required to access this resource" error, so I changed the annotations to:

@RunWith(SpringRunner.class)
@WebMvcTest(controllers=OurController.class)
@AutoConfigureMockMvc(secure=false)

But it resulted in the same "No qualifying bean found for dependency [org.springframework.security.config.annotation.ObjectPostProcessor]: expected at least 1 bean which qualifies as autowire candidate" as the previous error. I even emailed the author of that article and he replied saying he's never seen this error.

Can anyone explain why the @WebMvcTest annotation isn't working for me?

Answer 1

Give a look at your project and ensure it doesn't have the @ComponentScan annotation. I had problem with it and @WebMvcTest just like you had. I have mine working like this:

@RunWith(SpringRunner.class)
@WebMvcTest(controllers = { SomeEntityController.class })
public class SomeEntityControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @MockBean
    private SomeEntityService someEntityService;

    private MediaType contentType = new MediaType(MediaType.APPLICATION_JSON.getType(), MediaType.APPLICATION_JSON.getSubtype(), Charset.forName("utf8"));

    @Before
    public void setup() {

        List<SomeEntity> someEntitys = new ArrayList<>();
        SomeEntity someEntity = new SomeEntity();
        someEntity.setId(new Long(1));

        someEntitys.add(someEntity);

        when(someEntityService.findAll()).thenReturn(someEntitys);
    }

    @Test
    public void findAll() throws Exception {

        ResultActions actions = mockMvc.perform(get("/someEntity/findAll"));

        actions.andExpect(status().isOk()).andExpect(content().contentType(contentType));
    }
}

@RestController
@RequestMapping("/someEntity")
public class SomeEntityController {

    @Autowired
    private SomeEntityService someEntityService;

    @GetMapping(value = "/findAll")
    public List<SomeEntity> findAll() { 
        return someEntityService.findAll();
    }

}

@SpringBootApplication
public class SomeEntityApplication {
    public static void main(String[] args) {
        SpringApplication.run(SomeEntityApplication.class, args);
    }
}

The @WebMvcTest#secure property is true by default. If you have spring-security-test as a test dependency, then spring security will take affect during the test (which can be switched off by setting WebMvcTest#secure to false). However, if your controller is making use of Authentication or its principal, you'll probably have failing tests.

So, you can make use of @org.springframework.security.test.context.support.WithMockUser which will create an authenticated user with username user and password password. In doing so, your test should no longer fail because of authentication (but possibly with authorization).

I suggest you take a look at spring's documentation about testing here.
