Spring Download 1.4.2 @WebMvcTest returns 404

Question

I am using Spring Boot 1.4.2 and Jersey (jax-rs) to create a REST controller. I followed the documentation on how to test REST controllers ( Testing Spring MVC Slice ). But my test returns 404, and I cannot understand why. The controller is simplified here, but the problem remains.

My question is: how to get status 200 when running the test?

HealthController.java

@Controller
@Path("/health")
public class HealthController {
    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Health health() {
        return Health.up().build();
    }
}

Starting the server and executing the request gives me this

%> curl -i http://localhost:8080/health
HTTP/1.1 200 
X-Application-Context: application
Content-Type: application/json
Content-Length: 21
Date: Sun, 27 Nov 2016 15:22:30 GMT

{
  "status" : "UP"
}% 

HealthControllerTest.java

@RunWith(SpringRunner.class)
@WebMvcTest(HealthController.class)
public class HealthControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void health() throws Exception {
        mockMvc.perform(get("/health").accept(MediaType.APPLICATION_JSON))
                .andExpect(status().isOk()); // 200 expected
    }
}

This is what I get when running the test.
