Quizplus · Accepted Answer

Black-box and white-box are the two main approaches to unit testing. Black-box testing is when the tester only looks at the inputs and outputs of a function without examining the internal workings. White-box testing is when the tester looks at the internal workings of the function to ensure that it is working correctly. Both approaches are important and should be used together for comprehensive unit testing.
