path coverage testing

path coverage testing

(testing)Testing a program by examining which lines ofexecutable code are visited (as in code coverage testing)and also the ways of getting to each line of code and thesubsequent sequence of execution.

Path coverage testing is the most comprehensive type oftesting that a test suite can provide. It can find morebugs, especially those that are caused by data coupling.However, path coverage is hard and usually only used for smalland/or critical sections of code.
