Perl Code Kata: Mocking Objects (O'Reilly)

[Posted April 13, 2005 by cook]

Stevan Little explores Perl's DBD::Mock on O'Reilly. "Mock objects are exactly what they sound like: "mocked" or "fake" objects. Through the power of polymorphism, it's easy to swap one object for another object which implements the same interface. Mock objects take advantage of this fact, allowing you to substitute the most minimally mocked implementation of an object possible for the real one during testing. This allows a greater degree of isolation within your tests, which is just an all around good thing."
