使用Mockito:参数不同！想要:实际调用有不同的参数:

Question

当我像这样运行 JUnit 测试时：

@Test
public void insertSignRewardTest() throws Exception{
    SignRewardRequest srr = new SignRewardRequest();
    srr.setBeginTime(new Date().toLocaleString());
    srr.setPoint(21);
    srr.setUseableId("123");
    srr.setEndTime(new Date().toLocaleString());
    SimpleDateFormat sFormat = new SimpleDateFormat("yyyy-MM-dd");
    PointRewardDeploy pointRewardDepoly = new PointRewardDeploy();
     Date reward_begin_date = new Date();
     Date reward_end_date = new Date();
     reward_begin_date = sFormat.parse(srr.getBeginTime());
     reward_end_date = sFormat.parse(srr.getEndTime());
    pointRewardDepoly.setPoint_source_type(Long.valueOf(PointSourceType.SIGNED.getValue().toString()));
     pointRewardDepoly.setCreate_time(new Date());
     pointRewardDepoly.setUpdate_time(new Date());
     pointRewardDepoly.setReward_begin_date(reward_begin_date);
     pointRewardDepoly.setReward_end_date(reward_end_date);
     pointRewardDepoly.setStatus(1l);
     pointRewardDepoly.setReward_point(srr.getPoint());
    List<PointRewardDeploy> listPointRewardDeploy = new ArrayList<PointRewardDeploy>();
    listPointRewardDeploy.add(pointRewardDepoly);
    CommonListResult<PointRewardDeploy> cr = new CommonListResult<PointRewardDeploy>();
    cr.setCode("success");
    cr.setMsg("ok");
    cr.setSuccess(true);
    List<PointRewardDeploy> date = new ArrayList<>();
    date.add(pointRewardDepoly);
    cr.setData(date);
    ObjectMapper mapper = new ObjectMapper();
    String str = mapper.writeValueAsString(srr);
    when(pointAccountService.savePointRewardDeploy(listPointRewardDeploy)).thenReturn(cr);
    this.mockMvc.perform(MockMvcRequestBuilders.post("/api/sign/signPrizeDraw/insertSignReward")
            .contentType(MediaType.APPLICATION_JSON)
            .content(str))
    .andDo(print())
    .andExpect(status().isOk());
    Assert.assertEquals(true, cr.getSuccess()); 
    verify(pointAccountService,times(1)).savePointRewardDeploy(refEq(listPointRewardDeploy));
}

我在以下位置使用org.mockito.Matchers.refEq：

verify(pointAccountService,times(1))
    .savePointRewardDeploy(listPointRewardDeploy) 
verify(pointAccountService,times(1))
    .savePointRewardDeploy(refEq(listPointRewardDeploy))

然后运行它，它通过了测试，但打印输出消息为空，例如：

MockHttpServletRequest:
HTTP Method = POST
Request URI = /api/sign/signPrizeDraw/insertSignReward
Parameters = {}
Headers = {Content-Type=[application/json]}
Handler:
Type = com.yirendai.mplatform.sign.controller.UserInfoListController
Method = public 
Async:
Async started = false
Async result = null
Resolved Exception:
Type = null
ModelAndView:
View name = null
View = null
Model = null
FlashMap:
Attributes = null
MockHttpServletResponse:
Status = 200
Error message = null
Headers = {}
Content type = null
Body = 
Forwarded URL = null
Redirected URL = null
Cookies = []

我的问题：打印消息是否正确？我认为这是不正确的，但不知道如何解决它。谢谢你帮助我。

Answer 1

打印输出对我来说看起来是正确的，但是如果不看到映射到/api/sign/signPrizeDraw/insertSignReward的控制器方法，就很难确定，特别是：该方法返回的内容。

如果您希望body包含在打印输出中，则：

• 请求中未打印body
• 仅当响应包含body时，响应中才会打印body

请记住，print()不是 MVC 层的正式输出，它只是一个(有时(有用的诊断工具。只要你测试...

• 状态代码
• 响应内容和类型(如果控制器方法返回某些内容(
• 任何副作用，以对控制器下方层的验证或期望的形式(例如服务或存储库调用(

。那么我认为您的 MockMvc 测试用例就足够了，您无需关心print()输出的结果。
