JUnit Examples

JUnit 4 supports parameterizing a Test class to run the test methods in the class with multiple data values.

There are many differences between JUnit 4 and 5, in terms of JUnit 5 having more capabilities and different ways of doing stuff.

But there are some very obvious differences between 4 and 5 in terms of: ignoring tests, running methods before and after methods and test classes, and exception asserting.

To generate JUnit HTML reports from maven builds we need to add the surefire plugin to generate the xml files and then the site and reporting plugins to create the html report.

I prefer to use either JUnit 4 or JUnit 5, but there may be moments when we want to use both. We can do that with JUnit 5 dependencies.
