Accordingly, how does JUnit testing work?
A JUnit test is a method contained in a class which is only used for testing. This method executes the code under test. You use an assert method, provided by JUnit or another assert framework, to check an expected result versus the actual result. These method calls are typically called asserts or assert statements.
