EasyMock: Void Methods

Question

I have a method that returns void in a class that is a dependency of the class I want to test.

This class is huge and I\'m only using this single method from it. I n

In situations like these I've found that making a nested class in my unit test class and overriding the methods with special requirements in that way is the best route. So if you're testing ClassA which has that method with the parameters you need to access, you'd do something like:

class MockClassA extends ClassA {
    @Override
    void specialMethod(String param1, String param2) {
        // do logging or manipulation of some sort
        super.specialMethod(param1,param2); // if you need to
    }
}

In my unit testing code, I then just use this instance instead. Just treat it as if it was any other mock object. Much easier than mixing libraries, which I agree is probably not a good idea.
