01How would you standardize Selenium vs Playwright across multiple teams as a technical lead or architect?
A technical-leadership 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
- make the decision criteria visible across teams and create a safe default path.
- 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 -- --runInBandEvidence 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 reviewPractice prompt: Explain the escalation route when false confidence from brittle automation conflicts with delivery pressure.
