It provides one API that works in any browser on any platform, with listed attributes including:

  • Cross-browser. Playwright supports all modern rendering engines including Chromium, WebKit and Firefox.
  • Cross-platform. Test on Windows, Linux and macOS, locally or on CI, headless or headed.
  • Cross-language. Use the Playwright API in TypeScript, JavaScript, Python, .NET, Java.
  • Test Mobile Web. Native mobile emulation of Google Chrome for Android and Mobile Safari. The same rendering engine works on your Desktop and in the Cloud.

To get a handle on Playwright and learn the skills and knowledge needed to become a web automation wizard, Randy Pagels, a DevOps architect at Xebia, will present an introductory session titled "Mastering Application Testing: Scaling and Continuous UI Testing with Playwright" at the upcoming Visual Studio Live! developer conference in Las Vegas in March.
