< testing > 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 in a program, especially those that are caused by data coupling . However, path coverage is a testing level that is very hard to achieve, and usually only small and/or critical sections of code are checked in this way.
