Junit java类中的多个@Test方法因java.lang而失败。异常：没有可运行的方法

我在一个类中有多个@Test方法，当运行paxexam时，它失败了，出现以下异常

java.lang.Exception: No runnable methods

这是因为junit库在karaf容器中被初始化了两次。谢谢大家的帮助。

你能给我们看一下代码吗。你是在导入

org.junit.Test

还是像

org.testng.annotations.Test这样的东西吗？我已经在问题中添加了代码，请看一看我正在导入org.junit.Test可能org.junit包有两个不同的包。你的测试课使用其中一个，而Pax考试使用另一个。如果是这种情况，请通过控制台或网络控制台检查接线；或者调试并查看测试类的类加载器在代码中是否与BlockJUnit4ClassRunner中的类加载器相同
