I decided to make a quick video and run through creating a simple test with JUnit. In the video I create an basic acceptance test for a method.
I may turn this into a series of videos showing the different things that JUnit can do and the advantages of tests and TDD(Test-driven development).
In this example I have created a test for a Calculator class that has an Add method. The Add method takes in two integers and sums them together.
Setting up a test in JUnit is very easy. Tests increase the quality of code based and give you confidence in your code. In this example I set up an assertEquals check to see if I get the expected results. If they match the test will return true and pass, if not it will return false, fail and show you the expected result.

Thanks for reading/watching and I hope this helps.
