Using Mocks And Tests To Design Role-Based Objects

摘要

Within the realm of Test-Driven Development (tdd),rnmock objects can help you discover the roles that objects should play within a system, emphasizing how the objects relate to each rather than their internal structure. This technique can be employed to support good object-oriented design. Using mock objects as an aid to design turns out to be much more interesting than the common practice of using them simply to isolate a system from external dependencies.
