“What is requirements-based testing?” By: Gary E. Mogyorodi
“The requirements-based testing (RBT) process is comprised of two phases: ambiguity reviews and cause-effect graph- ing. An ambiguity review is a technique for identifying ambiguities in functional1 requirements to improve the quality of those requirements. Cause-effect graphing is a test-case design technique that derives the minimum number of test cases to cover 100 percent of the functional requirements.
Testing can be divided into the follow- ing seven activities:
1. Define Test Completion Criteria.
The test effort has specific, quantifiable goals. Testing is completed only when the goals have been reached (e.g., testing is complete when the tests that address 100 percent functional coverage of the system all have executed successfully).
2. Design Test Cases. Logical test cases are defined by four characteristics: the initial state of the system prior to exe- cuting the test, the data, the inputs, and the expected results.
3. Build Test Cases. There are two parts needed to build test cases from logical test cases: creating the necessary data, and building the components to sup- port testing (e.g., build the navigation to get to the portion of the program being tested)……..”
