A test lead hears “we need regression on the mash-temperature predictor” and books a full re-run of last sprint’s functional suite. The data scientist meant a continuous-value supervised model. What distinction should the tester keep?
Select an answer to reveal the explanation.
Short Explanation
When a data scientist says regression on the mash-temperature predictor, they mean a continuous-value supervised model. That is not a full re-run of last sprint's functional suite. Keep ISTQB change-related regression testing off that word.
Full Explanation
Reject the Foundation-level “regression testing” reading of ML regression. The data scientist meant a continuous numeric supervised model, not a change-related re-run, clustering, or a reward loop.
