| Basis path testing - | (Software Engineering) a white box test case design technique that used the algorithmic flow of the program to design tests |
| Black box testing - | (Software Engineering) testing that does not focus on the internal details of the program but uses external requirements |
| Boundary value analysis - | (Software Engineering) a black box testing method that designs test cases that exercise data boundaries |
| Cause-effect graphing - | (Software Engineering) a black-box testing method |
| Complexity - | (Software Engineering) a quantitative measure of a program's complexity |
| Corrective maintenance - | (Software Engineering) finding and fixing defects that have been reported by users |
| Coupling - | (Software Engineering) an informal measure of the degree to which a software component is connected to other components, to data, and to the external environment |
| Cyclomatic complexity - | (Software Engineering) a measure of the logical complexity of an algorithm, used in white-box testing |
| Enhancement - | (Software Engineering) an extension of functional or performance requirements |
| Equivalence partitioning - | (Software Engineering) a black-box testing method |
