java – Intellij IDEA完全不会识别测试文件夹中的测试

我使用JUnit,因为我开始这个项目,一切都很好.我有几百个测试,当然,这里和那里我启动他们.右键单击根测试文件夹,使用JUnit运行(或调试).
但是从昨天起,当我这样做,结果是：

Process finished with exit code 0

没有开始任何测试.与文件夹树中的任何文件夹相同.我仍然可以运行一个单独的测试类,但我真的需要一个选项来启动它们.
如果您有任何想法,请将它们放在这里.

以下是当我尝试运行测试时记录的内容：

解决方法

好的,我修好了

在菜单中,在文件下,有一个无效的缓存选项.那固定了！
