有没有人有任何提示，或者有人知道如何测试HTTP响应对象返回的“错误消息”吗？
@Autowired
private WebApplicationContext ctx;
private MockMvc mockMvc;
@Before
public void setUp() throws Exception {
mockMvc = MockMvcBuilders.webAppContextSetup(ctx).build();
}
响应：
MockHttpServletResponse:
Status = 200
Error message = null
Headers = {Content-Type=[application/json;charset=UTF-8]}
Content type = application/json;charset=UTF-8
您可以使用该方法 status.reason（）。
例如：
@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 = []
