UISpec4J测试与其他JUnit测试用例冲突

我有一堆JUnit测试用例

最近，为了在我的应用程序中测试GUI，我使用了UISpec4JAPI

当我单独运行GUI测试时，不会有任何问题

但是，当我使用之前的JUnit测试用例将GUI测试添加到测试套件中时，它显示了很多错误

其中一些是NoClassDefFoundError、UnsatisfiedLinkError等等

为什么会发生这种情况

下面是我的堆栈跟踪

你能把stacktrace贴出来吗？在没有任何信息的情况下调试您的问题是非常困难的，我已经找到了解决方案。由于我使用EclEmma，我可以通过独立运行两个测试来合并覆盖率会话，然后合并它们的结果。但实际上不应该有冲突，无论如何，在某个地方有一个错误。
