Follow-up Test Case
A follow-up test case is an additional test created after an initial test to further investigate a defect, verify related functionality, or explore newly discovered behavior.
“A test case generated by applying a metamorphic relation to a source test case during metamorphic testing.”

Follow-up test cases help testers expand coverage when unexpected results or defects reveal additional scenarios worth testing.
Investigation: New tests explore related conditions or edge cases.
Adaptive testing: Additional tests are created based on previous outcomes.
Quality improvement: Helps uncover related defects that initial tests missed.
Real World Example
A regulated product team is preparing a release where Follow-up test case appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Follow-up test case as interchangeable with nearby ISTQB terms. That makes test scope blurry and can lead to weak evidence for the release decision.
The tester anchors the discussion in the official definition, asks where the concept appears in the product, and designs examples that show the difference between Follow-up test case and similar ideas.
The page becomes useful in practice because Follow-up test case is connected to a specific testing decision, not memorized as a detached definition.
