所以我在这里根据参考指南设置了power mock .这一切似乎都可以通过单个测试类完美运行.但是当执行多个JUnit测试时,我在第二个测试类上遇到以下错误.

正如您从下面的堆栈跟踪中看到的,我正在尝试模拟一个otto Bus实例.它似乎在第一个测试类上正确模拟,但在第二个类上我得到了这个类转换异常.

在堆栈跟踪上我得到了禁用Objenisis缓存的建议,但我不知道如何实现这一点,如果这实际上是根本原因,因为我正在使用classloading-xstream:1.6.2根据上面附带的Robolectric Wiki链接.

如果我运行一个JUnit测试类,那么我的设置很有效,但是一旦我尝试在一个包中运行所有测试,只有第一个测试可以工作,后续测试将获得类强制转换异常.

org.mockito.exceptions.base.MockitoException: 
    ClassCastException occurred while creating the mockito proxy :
      class to mock : 'com.squareup.otto.Bus', loaded by classloader : 'org.robolectric.internal.bytecode.InstrumentingClassLoader@1593948d'
      created class : 'com.squareup.otto.Bus$$EnhancerByMockitoWithCGLIB$$82a3b196', loaded by classloader : 'org.robolectric.internal.bytecode.InstrumentingClassLoader@1593948d'
      proxy instance class : 'com.squareup.otto.Bus$$EnhancerByMockitoWithCGLIB$$82a3b196', loaded by classloader : 'org.mockito.internal.creation.util.SearchingClassLoader@618ff5c2'
      instance creation by : ObjenesisInstantiator

    You might experience classloading issues, disabling the Objenesis cache *might* help (see MockitoConfiguration)
