==== Lab 3: Introduction to JUnit ==== 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: https://netbeans.org/kb/docs/java/junit-intro.html 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 https://github.com/Vassar-cs203/.git . Be sure you are in your CS203 directory when you execute the github commands.
