【问题描述】：
条件场景加载ApplicationContext失败
问题是 2 个存储库测试类将 fail to load the ApplicationContext 用于该测试类的第一个测试用例，如果在该类之前运行任何其他测试。
Project on Github“修复单元测试”分支
我使用 Mongodb Embedded 数据库对 spring-boot maven 应用程序进行了一系列 JUnit 组件测试。
2 个测试类在 2 个 spring-repositories 上运行单元测试。
但是，自己运行的测试类完全可以正常工作，有时在它们之前执行另一个测试时。
我需要帮助解决 ApplicationContext 未加载问题。救命？？？
场景： 两个测试类运行了两次。
所有测试都运行了两次：第二次运行完全没有问题。
错误日志：

如果你在日志中往下看，你可以看到这是因为你缺少一个 bean，你需要以某种方式自动装配或注入它们。从探索 CvController 开始，然后往下走：
Error creating bean with name 'cvController' defined in file [/Users/tony/Documents/qac-cv-management-system/backend/target/classes/com/qa/controller/CvController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'cvService' -
试过了。结果相同。失败的测试类根本不使用 CvController 或 CvService。据我所知，这是使用不正确的 ApplicationContext 可能来自之前测试中的错误。
