我开始进行单元测试。我对一个没有注入SessionContext的类进行了改变，所以我可以在需要时进行查找。现在使用mockito嘲笑SessionContex导致ClassNotFoundException
@Resource
private SessionContext ctx;
，在我的测试，我想注入，所以我可以嘲笑查找方法：
@Mock
private SessionContext ctx;
但是当我运行测试，我得到：

我觉得很奇怪，因为我有所有需要的依赖关系（这个代码在真正的应用程序中工作）。
如何使用mockito模拟并注入SessionContext？ （我不能改变模拟框架）。
