Given the importance of early testing we will be using a unit-test framework called junit4 in our programs. There is a very short intro to junit at the end of chapter 3 (pages 131-133) which you should read before starting. Then, go to the following site and work through the exercise on junit:

NOTE: Start at the top of the page, and skip the junit3 steps, we will use junit4.

NOTE: Create a folder under your CS203 folder for this project, called JUnitLab. Put your project in this folder.

When you are done with the exercise, which should have the code in a folder under your cs203 directory, save your CS203 directory to your PRIVATE github repository. Your github address should look like<email name>.git . Be sure you are in your CS203 directory when you execute the github commands.
