Cross-browser and cross-device testing — quiz

A web app works perfectly in Chrome but fails silently in Safari. The dev says, "We use modern web standards, so it should just work everywhere." What's the right tester response?

• Trust the dev's reasoning and close the bug as not-reproducible
• File the bug — "should work" is a hypothesis until validated; real Safari users are seeing real failures
• Recommend dropping Safari support entirely
• Block the release until the dev rewrites everything in vanilla JS
