Unit testing is a form of white box testing, in which test cases are based on internal structure. The tester chooses inputs to explore particular paths, and determines the appropriate output. The purpose of unit testing is to examine the individual components or pieces of methods/classes to verify functionality, ensuring the behavior is as expected.
