Real-Time Playwright Interview Questions for QA Testers

These questions focus on practical scenarios faced by Playwright Automation Testers and SDETs, including UI automation, API testing, debugging, test frameworks, and CI/CD.

1. Real-Time Scenario Questions — Freshers

1. Login Functionality: You need to automate a login page with valid and invalid credentials. How would you write the test and verify the expected results?

2. Element Not Found: Playwright cannot locate the Login button even though it is visible in the browser. How would you investigate the issue?

3. Dynamic Web Elements: A button’s ID changes every time the page loads. How would you create a reliable locator?

4. Form Validation: You submit a registration form with empty mandatory fields. How would you verify the validation messages?

5. Dropdown Validation: You need to select a country from a dropdown and verify the selected value. How would you do this in Playwright?

6. Page Navigation: After clicking Submit, the application navigates to a dashboard. How would you verify that the navigation completed successfully?

7. Table Validation: A webpage displays 100 employee records. How would you search for a particular employee and validate their details?

8. Screenshot Capture: A test fails unexpectedly. How would you capture a screenshot to help investigate the failure?

2. Real-Time Scenario Questions — 1–3 Years

9. Flaky Test: Your test passes locally but fails intermittently in CI. How would you identify the root cause?

10. Multiple Matching Elements: Playwright finds three buttons named Submit. How would you identify and click the correct one?

11. New Browser Tab: Clicking a link opens a new tab. How would you switch to that page and validate its title?

12. Iframe Testing: A payment form is displayed inside an iframe. How would you enter card details and validate the form?

13. File Upload: You need to upload a PDF document and verify that the application accepts it. How would you automate this scenario?

14. File Download: Your application generates an invoice after payment. How would you verify the download and check the file?

15. Authentication Reuse: You need to execute 50 tests without logging in before every test. How would you reuse an authenticated session safely?

16. API Response Validation: An API returns HTTP 200, but the response contains incorrect customer information. How would you identify the failure?

17. Test Data Parameterization: You need to test login with 20 combinations of valid and invalid credentials. How would you avoid duplicating test code?

18. Browser Compatibility: A test passes in Chromium but fails in Firefox. How would you investigate and isolate the problem?

3. Real-Time Scenario Questions — 3–6 Years

19. Framework Design: Your team needs a reusable Playwright framework for login, checkout, payment, and order management. How would you organize page objects, fixtures, utilities, and test data?

20. Parallel Execution: Tests pass individually but fail when executed in parallel. What shared-state and test-isolation problems would you investigate?

21. Network Failure: An external API occasionally returns HTTP 503. How would you test the application’s error handling without depending on the live service?

22. Request Interception: You need to mock an API response and verify that the frontend displays the correct data. How would you use Playwright routing?

23. API and Database Mismatch: The UI displays an order total that differs from the database value. How would you investigate the issue and identify which layer is responsible?

24. Slow Regression Suite: Your regression suite takes four hours to run. How would you optimize execution without compromising test reliability?

25. Debugging with Trace Viewer: A test fails only in CI, and the screenshot does not reveal the cause. How would you use Playwright traces, logs, and network information?

4. Real-Time Scenario Questions — 6–12 Years

26. Enterprise Framework: You need to support multiple applications, environments, browsers, and QA teams. How would you design a scalable Playwright architecture?

27. Massive Parallel Execution: Hundreds of tests run across multiple CI workers, but they sometimes update the same customer or order records. How would you prevent data conflicts?

28. Flaky Test Management: Your suite has a 15% intermittent failure rate. How would you classify failures, identify root causes, and decide when retries or quarantining are appropriate?

29. Selenium to Playwright Migration: Your organization has 2,000 Selenium tests. How would you plan a phased migration to Playwright while keeping releases stable?

30. Release Quality Strategy: Your team must release a critical application within two hours. How would you select smoke tests, regression tests, API checks, and cross-browser tests to make a release decision?
