JUnit belongs to a family of testing frameworks collectively called xUnit. The SUnit is the grandfather of this family and was designed by Kent Beck in 1998 for the Smalltalk language.

We need some of the following nomenclature before carrying on. The nomenclature is not specific to JUnit, but we will use JUnit as an example to make it easier to relate to the definitions.
Test runner: A test runner runs tests that are defined by an xUnit framework.
JUnit has a way to run unit tests from the command line, and Maven employs a test runner called Surefire. A test...
