Your question is Prioritize Testing Under Time Pressure. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You are preparing a release and realize the full regression suite will not finish before the deployment window. You need to decide what to test first so the highest-risk areas are covered, while still giving stakeholders confidence that the release is safe enough to ship.
How do you prioritize test cases when time is constrained?
