White-box methods and comparisons
Once white-box testing is started, there are a number of techniques to ensure the internal parts of the system are being adequately tested and that there is sufficient logic coverage.
The execution of a given test case against program p will exercise (cover) certain parts of P's internal logic. A measure of testedness for p is the degree of logic coverage produced by the collective set of test cases for P. White-box testing methods are used to increase logic coverage.
There are four basic forms of logic coverage:
(1) Statement coverage
(2) Decision (branch) coverage
(3) Condition coverage
(4) Path coverage.
