path coverage testing

Computing Dictionary

path coverage testing definition

Testing a program by examining which lines of executable code are visited (as in code coverage testing) and also the ways of getting to each line of code and the subsequent sequence of execution.
Path coverage testing is the most comprehensive type of testing that a test suite can provide. It can find more bugs, especially those that are caused by data coupling. However, path coverage is hard and usually only used for small and/or critical sections of code.
