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

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

错误日志如下：

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？
