Guide to Writing Testable Code

Thank you for your good post. I have a question about "Flaw #2: Digging into Collaborators" and "Dynamic type casting". "Dynamic type casting" means casting from one interface type to another interface type in Java or C#. Or I think QueryInterface() of COM does same thing. My question is that: Casting the interface,which is passed in, to another interface conforms to Flaw #2, Or Not. Thanks. Hyun
