Spring MockMvc Fails : No mapping found for HTTP request with URI

Question

I have a GET method in my REST API

This is my controller class

@RestController
@RequestMapping("/api")
@Validated
public class ApiController {

@Autowired
private ApiService service;

@GetMapping(path = { "/check/{type}", "/check" }, 
produces= {MediaType.APPLICATION_JSON_UTF8_VALUE,MediaType.APPLICATION_XML_VALUE})
    public List<Myobject> check(@MyConstraint @RequestParam("email") final List<String> emails,
            @PathVariable(name = "type", required = false) final String type) {
        final String subscriptiontype = StringUtils.isEmpty(type) ? "all" : type;
        final List<Myobject> objects= service.check(emails, subscriptiontype);

    return objects;
}

}

I'm trying to write a Unit Test For this controller class

@RunWith(SpringRunner.class)
@WebMvcTest(controllers = SubscriberApiController.class)

public class ApiControllerTest {

private MockMvc mvc;

@Autowired
private WebApplicationContext webApplicationContext;

@MockBean
private ApiService service;

@Before
public void setUp() {
//  mvc = MockMvcBuilders.standaloneSetup(new HandlerController()).build();
    mvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}

@Test
public void getIndex() throws Exception {
    mvc.perform(get("/my-service/api/[email protected]").accept(MediaType.APPLICATION_JSON))
       .andExpect(status().isOk());

}
}

But it's showing me mapping error No mapping found for HTTP request with URI

My ciontext root is not getting mapped to servlet

server.servlet.contextPath=/my-service

if I change test to

 mvc.perform(get("/api/[email protected]").accept(MediaType.APPLICATION_JSON))
       .andExpect(status().isOk());

It works fine

Update

http://localhost:8080/my-service/api/[email protected]

Could some one tell me What's wrong here ???

Answer 1

The MockMvc is a mock and it is not load context path from the server configuration. You must add contextPath to your mockMvc object:

mvc.perform(get("/my-service/api/[email protected]")
    .contextPath("/my-service")
    .accept(MediaType.APPLICATION_JSON))
    .andExpect(status().isOk());
