mockito中的测试失败消息：参数不同！需要：（2个答案）
上个月关门了。
我是后端测试的新手，我正在用mockmvc测试我的spring启动应用程序。但是，当我想测试我的post请求时，我在使用时遇到了标题中提到的错误

verify(userService,atLeastOnce()).addUser(user1);

错误日志如下：

{"id":1,"name":"Burakhan Aksoy","email":"burak@burak.com","gender":"Male","phoneNumber":"12321"}

MockHttpServletRequest:
      HTTP Method = POST
      Request URI = /users
       Parameters = {}
          Headers = [Content-Type:"application/json;charset=UTF-8", Content-Length:"96"]
             Body = {"id":1,"name":"Burakhan Aksoy","email":"burak@burak.com","gender":"Male","phoneNumber":"12321"}
    Session Attrs = {}

Handler:
             Type = io.thebman.restapitesting.controllers.UserController
           Method = io.thebman.restapitesting.controllers.UserController#addUser(User)

Async:
    Async started = false
     Async result = null

Resolved Exception:
             Type = null

ModelAndView:
        View name = null
             View = null
            Model = null

FlashMap:
       Attributes = null

MockHttpServletResponse:
           Status = 201
    Error message = null
          Headers = [Content-Type:"application/json"]
     Content type = application/json
             Body = {"id":1,"name":"Burakhan Aksoy","email":"burak@burak.com","gender":"Male","phoneNumber":"12321"}
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

Argument(s) are different! Wanted:
io.thebman.restapitesting.service.UserService#0 bean.addUser(
    io.thebman.restapitesting.view.User@1b5a1d85

尝试重载默认值 hashCode() 以及 equals() 方法。
在您的场景中，它考虑两个不同的对象，并基于默认对象的方法进行比较，该方法检查地址。
编辑：作为这个测试用例的一部分，您只需要重写 equals() 方法。但没能超越 hashCode() ，以后使用任何 Hash 相关收藏，如 HashTable, HashMap etc. 请参阅本文了解更多详细信息：为什么需要重写java中的equals和hashcode方法？
