Tests for Design Change

A development cycle begins with existing artifacts. During the model development lifecycle, the model evolves through enhancements and bug fixes. These changes often affect only limited portions of the model, making it essential to validate the modified logic while minimizing unnecessary rework. To improve efficiency, reuse existing test cases wherever possible and avoid generating new ones unnecessarily. When the model contents change but the interface remains unchanged, you can reuse existing test cases to measure coverage. If the interface changes, you must update the test cases accordingly. Incremental test‑generation workflows reuse or update existing artifacts and create additional ones as needed, significantly reducing overall verification effort.
