我正在设置一个integrationtest来检查spring应用程序是否在控制器级别工作，旁边是我的单元测试。我确实知道我正在测试的工作，单元测试工作，我已经用postman做了所有的事情。每个integrationtest也单独工作，并给出我期望它给出的结果。问题是当我一起运行它们时，有些测试不再工作了。这是因为MockMvc应该在每次测试时都被更新，但事实并非如此。
我尝试通过手动设置mockMvc来获得这种行为，而不是将其注入到构造函数中，但同样的行为仍然存在。我想我设置MockMvc是错误的，但我似乎无法弄清楚如何正确设置它。我使用Sping Boot 3和Java 20。
我应该如何创建mock，以便它在每个测试中再次运行，并且不会受到其他测试的影响？我将testclass放在下面。
