testing void method with EasyMock

Question

I need to test sorting class which takes a array of certain interface type. The interface only has one function which only compare an object and return some int value. I am trying to use easymock to test it with jUnit. I am stuck with two problems. First, I need to assign some value to the each mock object that I created for the given interface.

mock[0] = EasyMock.createMock(CompareValue.class);

How can I assign some value to mock[0]? The interface CompareValue only has following method:

int compareVal(Object obj);

the object is going to be a CompareValue type in the sorting class

Second, I only have static void method in the class which takes a list and modifies it but dont return anything. I am not suppose to change any code in interface or class.I dont know how to retrieve that modified list to check if it has been sorted correctly.

Override the getter instead of assigning a value to the mock.

expect(mock[0].getValue()).andRetun(yourValue);

there is no getValue() method in the interface. Is there any way in which I can directly assign value to the mock object? – Ramy Apr 08 '12 at 01:02
I think the only possible way is to implement an inner class – Ramy Apr 08 '12 at 01:09
Can you please provide some details of the CompareValue class. – Stefan Birkner Apr 08 '12 at 16:10
