java.lang.AssertionError : Status expected:<200> but was:<201>

Question

嗨，我正在尝试在我的 Controller 中实现 junit。但我得到的是 201 而不是 200。

下面是我的 Controller

@RestController
@RequestMapping(value = "/treat")
public class TreatController {

  private final TreatService treatService;

@Autowired
  public TreatController(TreatService treatService){
    this.treatService = treatService;
  }

@PostMapping
  public ResponseEntity<CommonResponse> addNew(
      @RequestBody Treat treat) throws RecordNotFoundException{
    CommonResponse response = new CommonResponse();
    response.setStatus(CommonConstants.OK);
    response.setData(treatService.save(treat));
    return new ResponseEntity<>(response, HttpStatus.CREATED);
  }
}

接下来是我的 Junit 测试:

@RunWith(SpringJUnit4ClassRunner.class)
@WebMvcTest(TreatController.class)
public class TreatControllerTest {

  private RecordNotFoundException recordException = new RecordNotFoundException("");

  private final String title = "{\"title\" : \"title\"}";

  @Autowired
  private MockMvc mockMvc;

  @MockBean
  private TreatService treatService;

@Test
  public void addNew() throws Exception{
    Treatment treatment = new Treatment();

    given(treatmentService.save(
        Mockito.any(Treat.class))).willReturn(treat);
    mockMvc.perform(post("/treats")
    .content(title)
    .accept(MediaType.APPLICATION_JSON_VALUE)
    .contentType(MediaType.APPLICATION_JSON_VALUE))

    .andDo(print())
    .andExpect(status().isOk());

    Mockito.verify(treatService).save(Mockito.any(Treat.class));
  }
}

有什么我错过的吗？顺便说一句，我不使用 Json。我只是插入它，因为它有效。

这就是你返回的内容。

return new ResponseEntity<>(response, HttpStatus.CREATED);

HttpStatus.CREATED 返回 201 并指示请求已创建资源

在您的测试用例中，您期望 OK(200) .andExpect(status().isOk());

根据HTTP1.1/ specs Post 请求应该始终导致资源的创建。所以从那里返回 201 是有意义的。您所需要做的就是将测试用例断言预期值更改为 HTTPStatus.CREATED。
