| Toxicity | (Environmental Engineering) A U.S. EPA hazardous waste characteristic defined with a rigorous test procedure, the TCLP (for Toxicity Characteristic Leaching Procedure). In the procedure, a waste is extracted for 24 hours with an acetic acid solution. The acid extract is then analyzed for the presence of any of the contaminants listed in the procedure. |
| Basis path testing - | (Software Engineering) a white box test case design technique that used the algorithmic flow of the program to design tests |
| Basis set - | (Software Engineering) the set of tests derived using basis path testingBehavioral modeling - |
| Beta testing - | (Software Engineering) testing that is conducted by the user |
| 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 |
| Clusters - | (Software Engineering) a collection of program components (modules) that is tested as a group |
| Component reuse - | (Software Engineering) the ability to reuse a portion of a model, source code, test case, etc. |
| Cyclomatic complexity - | (Software Engineering) a measure of the logical complexity of an algorithm, used in white-box testing |
