EasyMock: Mocked object is calling actual method

Question

I've following code snippet in my unit test,

ClassToBeMocked mock = createMock(ClassToBeMocked.class); //I've statically imported EasyMock.*
mock.callMethod(); //This is a void method
expectLastCall();
replay(mock);

But when I run the test, instead of seeting up the expectaion, callMethod() is actually called. Am I doing something wrong?

I'm fairly new to EasyMock or any mocking framework and blocked because of this problem. Any help would be greatly appreciated.

Thanks, AndyS

This will happen if you are mocking a class with a 'final' method. EasyMock does not override a final method. If you cannot mock an interface, and you cannot change the method to non-final, you can use PowerMock along with EasyMock to get around this limitation. That specific use case is described here.
