mockMvc - Test Error Message

Question

Does anybody have any tips, or does anybody know how I can test the \"error message\" returned by the HTTP response object?

@Autowired
private WebApplicationCont         


        

Answer 1

This is the solution I found using JsonPath and MockMvc

this.mvc.perform(post(BASE_URL).contentType(MediaType.APPLICATION_JSON).content(responseJson)).andDo(print())
.andExpect(status().is5xxServerError())
.andExpect(jsonPath("$.message", is("There is an error while executing this test request ")));

Hope this helps.

Answer 2

Even simpler:

String error =  mockMvc...
    .andExpect(status().isUnauthorized())
    .andReturn().getResolvedException().getMessage();

assertTrue(StringUtils.contains(error, "Bad credentials"));

Answer 3

it works for me:

.andExpect( status().reason( "invalid.duplicate" ) )

Answer 4

You can use the method status.reason().

For example:

     @Test
     public void loginWithBadCredentials() {
        this.mockMvc.perform(
                post("/rest/login")
                        .contentType(MediaType.APPLICATION_JSON)
                        .content("{\"username\": \"baduser\", \"password\": \"invalidPassword\"}")
                )
                .andDo(MockMvcResultHandlers.print())
                .andExpect(status().isUnauthorized())
                .andExpect(status().reason(containsString("Bad credentials")))
                .andExpect(unauthenticated());
    }


    MockHttpServletResponse:
                  Status = 401
           Error message = Authentication Failed: Bad credentials
            Content type = null
                    Body = 
           Forwarded URL = null
          Redirected URL = null
                 Cookies = []
