Question 1

How would you create an enterprise strategy for Selenium vs Playwright across business units?

Accepted Answer

A principal-level answer Say this first: Selenium vs Playwright is a choice between approaches with different strengths. The useful answer is the decision rule, not a dictionary definition. Use a real scenario Imagine a checkout flow changed by several teams in the same release. The team must decide how to apply Selenium vs Playwright , verify the result, and explain the user impact. For an Automation Testing Engineer / SDET, attach the explanation to a risk-based test plan and failure report. Show judgment set decision rights, investment thresholds, and risk-based governance without centralizing every choice. Choose the option that fits the workload and constraints; do not present one option as universally superior. Call out false confidence from brittle automation and the control that reduces it. Concrete check npm test -- --runInBand Evidence to mention Track escaped defects, flaky-test rate, and feedback time . Say what baseline you compared against, what would trigger a rollback or escalation, and who owns the follow-up. request or change → guardrail / validation → Selenium vs Playwright → observable result → owner review Practice prompt: Tie the standard to customer impact, escaped defects, flaky-test rate, and feedback time, and a review cadence.
