Mid-LevelTest Automation & Frameworks
What is your approach to testing web applications across different browsers and devices?
- cross-browser
- responsive
- device testing
Answer it first, then compare. Nothing here is saved or scored.
Model answer
Strategy: (1) Run core tests on all target browsers (Chrome, Firefox, Safari/WebKit) in CI. (2) Use Playwright projects config to define browser matrix. (3) Responsive testing: use viewport sizes for mobile, tablet, desktop. (4) Device emulation for mobile-specific features (touch, geolocation). (5) Real device testing for critical flows via BrowserStack/Sauce Labs. (6) Prioritize browsers by user analytics data. Not every test needs every browser, focus cross-browser runs on critical paths.
What interviewers listen for
- Test architecture instinctsYou can defend why your suite is shaped like a pyramid, a trophy, or a honeycomb.
- Locator disciplineYou rank selector strategies by stability and explain when to break the rule.
- Flaky test ownershipYou debug to a structural fix instead of retry-until-green.
- Parallelisation literacyYou know how your framework isolates state, fixtures, and database access across workers.
