Black box testing implies that the selection of test data as well as the interpretation of test results are performed on the basis of the functional properties of a piece of software. Black box testing should not be performed by the author of the program (Thaller94, 92) who knows too much about the program internals. In new testing approaches, software systems are given a third external party for black box testing after having successfully finished the internal glass box testing exercises.

a black box is a testing method in which the tester has no knowledge of the inner workings of the program being tested. The tester might know what is input and what the expected outcome is, but not how the results are achieved
