Perl Code Kata: Mocking Objects (4 tags)
One problem with many examples of writing test code is that they fake up a nice, perfect, self-contained world and proceed to test it as if real programs weren't occasionally messy. Real programs have to deal with external dependencies and work around odd failures, for example. How do you test that? In this Perl Code Kata, Stevan Little presents exercises in using Test::MockObject to make the messy real world more testable.

How do you test your code adequately without going crazy writing scaffolding that has no chance of working anywhere but your test box? Stevan Little suggests that DBD::Mock can round out your test toolbox nicely in this Perl Test Kata.
