Your tests will be run against a correct implementation of Magazine.

Ideally, all of your tests should pass when run against this correct version.

Measures will also be collected on how thoroughly you have checked the member functions of the Magazine class.

Your tests will also be run against a number of buggy versions of the code. The goal here is to see if your tests are good enough to detect the bugs.
