Option C

Chris F. · Answer

C . Had something like this in a mock, regression testing is meant to confirm no new bugs were added after changes. Pretty sure that's what ISTQB wants here, not just verifying fixes or checking task completion. Disagree?

Liam F. · Answer

C tbh, B is tempting but ISTQB makes it clear it's about finding new defects after changes. Not about task completion status. Seen similar wording in practice tests.

Kevin · Answer

Yeah, C is correct. Official guide and ISTQB glossary always say regression testing looks for new defects after changes. Definitely worth double-checking these definitions in the official glossary, just to be sure.

Chloe J. · Answer

I don’t think it’s C here, B makes more sense to me. Regression checks could prevent a task from being marked as done if issues are found after a change. Pretty sure that’s the trap in this one.
