ClassCastException exception when running Robolectric test with Power Mock on multiple files

I would suggest to disable ClassCache of Mockito as suggested in the exception message . Here is how I disable Mockito ClassCache by adding a MockitoConfiguration class in Android Studio.

  1. Under your unit test directory, src/test/java, create a package directory that is exactly the same as Mockito configuration package, org/mockito/configuration.

  2. So under the full test directory src/test/java/org/mockito/configuration, add a new class named MockitoConfiguration.

  3. Overwrite the enableClassCache() method as following.

    package org.mockito.configuration;

    public class MockitoConfiguration extends DefaultMockitoConfiguration {

    @Override
    public boolean enableClassCache() {
        return false;
    }
}

  4. When you run your Unit test under src/java/test, your MockitoConfiguration should be loaded and Mockito class cache should be disabled.

Hope it helps.

So I solved this problem by adding 

@PowerMockIgnore({ "*.*" }) 
@PrepareForTest({ StaticClass1.class,StaticClass2.class })

That will make Power mock ignore all the classes. For my case PowerMock was classloading the Bus which in my code was actually mocked by Mockito.Once I added the annotations above all the classes in the testsuite worked without any errors.
