A grit-bin refill desk has no gold “hours-to-empty” for every bin. They run the candidate model and an alternative version on the same inputs and compare outputs. What should testers name that activity and the alternative?
Select an answer to reveal the explanation.
Short Explanation
No gold “hours-to-empty” for every bin, so testers run the candidate and an alternative version on the same inputs and compare outputs. That is back-to-back testing, with the alternative used as a pseudo-oracle. A/B testing’s job is a statistical winner, dynamic drift testing uses ranger head-counts, and metamorphic testing starts from a passed source.
Full Explanation
Back-to-back testing runs the same inputs on the SUT and an alternative version used as a pseudo-oracle. A/B winner selection, dynamic drift testing, and metamorphic testing are different activities.
