Junit Parameterized tests together with Powermock - how?

java junit powermock parameterized

I've been trying to figure out how to run parameterized tests in Junit4 together with PowerMock. The problem is that to use PowerMock you need to decorate your test class with 

@RunWith(PowerMockRunner.class)

and to use parameterized tests you have to decorate with 

@RunWith(Parameterized.class)

From what I can see they seem mutually excluded!? Is this true? Is there any way around this? I've tried to create a parameterized class within a class running with PowerMock; something like this:

@RunWith(PowerMockRunner.class)
class MyTestClass {
     @RunWith(Parameterized.class)
     class ParamTestClass {
          // Yadayada
     }
}

But unfortunately this doesn't do much good... The ParamTestClass still doesn't run with PowerMock support (not that surprisingly maybe)... And I've kind of run out of ideas so any help is greatly appreciated!

I had the same issue. Unfortunately it would not let me use a PowerMock Rule due to the JVM I had. Instead of the rule I used RunnerDelegate.

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(Parameterized.class)
