Software Testing: Defect prevention, defect detection and debugging
Testers use requirements as an oracle to verify the success or failure of their tests. Requirements Based Testing methodology in which the software's specifications drive the testing uses proven techniques, that is highly commercially and academically trusted, to ensure that requirements are accurate, complete, unambiguous, and logically consistent. Requirements based testing provides a process for first testing the integrity of the specifications. It then provides the algorithms for designing an optimized set of tests sufficient to verify the system from a black-box perspective. Find out how to design test cases to validate that the design and code fully implement all functional requirements. Determine which test design strategy—cause-effect graphing, equivalence class testing, orthogonal pairs, and more—to apply to your applications. By employing a requirements based testing approach, you will be able to quantify test completion criteria and measure test status.
