JUNIT TESTING

You will find the code for this project, including the Java source file for the class Magazine here or, if you are logged in to one of the CS Linux machines, at ~zeil/Assignments/cs350/unittest-magazine/. Note that what you are being provided is a skeleton for the Magazine class that defines the interface for that ADT, but does not implement it. This is consistent with the practice of Test Driven Development (TDD) in which you would develop your tests before writing the code to be tested. Because none of the member functions of Magazine have been implemented yet, your tests should probably all fail when run against this skeleton. Your challenge, as in any TDD project, is to design your tests so that a complete & correct implementation of Magazine will pass.

Prepare your JUnit4 test as a class edu.odu.cs.cs350.TestMagazine.
