A Follow-Up Test Case is part of metamorphic testing. It is created by applying a metamorphic relation to an existing test case.
Key Aspects:
1. Derived from a source test case
2. Uses metamorphic relations
3. Helps detect software defects
4. Expands test coverage
5. Useful for testing complex systems
Process of Creating Follow-Up Test Cases:
1. Identify metamorphic relations
2. Select source test cases
3. Apply relations to generate new cases
4. Execute both source and follow-up cases
5. Compare results to verify correctness
Follow-up test cases are particularly useful when testing systems where determining the correct output is difficult or impossible.
