Summary

Chapter Recap

You now understand what Playwright is, why it exists, and how it compares to Selenium and Cypress. More importantly, you know WHEN to pick it and when not to. Let us lock in the key points.

• Playwright was built by ex-Puppeteer engineers at Microsoft to fix the problems in existing automation tools
• Auto-wait checks 6 conditions before every action -- this alone kills most flaky tests
• Codegen records your actions and generates test code -- start fast, refine later
• Trace Viewer is a flight recorder -- screenshots, DOM, network, console, all in one timeline
• Playwright runs outside the browser, enabling multi-tab, cross-origin, and popup testing
• Selenium is mature but slow and flaky. Cypress is modern but architecturally limited. Playwright takes the best of both.
• Not for native mobile, desktop apps, or load testing -- use specialized tools for those
