Suggested Answer: C

According to the ISTQB Glossary, regression testing is performed to ensure that changes or modifications in the software have not introduced new defects. The primary purpose of regression testing is to verify that the existing functionality of the software remains unaffected by recent changes, enhancements, or bug fixes.

The syllabus states that regression testing helps in confirming that the recent modifications do not negatively impact the previously working functionalities of the software.

I thought regression testing was more about preventing tasks from being incorrectly marked as done, which might lean towards option B. But I'm not completely confident.

I feel like I've seen a question like this before, and it was about ensuring that modifications don't break existing functionality. So, C seems right to me.

I'm a little confused by the wording of this question. The ISTQB Glossary is a specific reference, so I'll need to make sure I really understand the definition of regression testing from that source before answering.

Hmm, I'm a bit unsure about this one. I know regression testing has to do with verifying changes, but I'm not totally clear on the specific purpose according to the ISTQB definition. I'll have to think it through carefully.
