Our team is currently using a legacy Selenium framework, but we're seeing significant flakiness with modern React-based UIs. We’re considering a migration to Playwright for better auto-waiting and shadow DOM support. For those who have switched, was the refactoring effort worth the performance gains in your CI/CD pipeline?

We made the switch from Selenium to Playwright last year for our enterprise SaaS platform, and the results were transformative. The biggest "pro" is the built-in auto-waiting mechanism which virtually eliminated the Thread.sleep hacks we were using to handle asynchronous elements in React. In terms of performance, our test execution time dropped by nearly 40% because Playwright handles multiple browser contexts within a single instance much more efficiently than Selenium's WebDriver. If you are dealing with complex web components or heavy shadow DOM usage, the refactoring effort is a one-time pain that pays off in reliability and lower maintenance costs within six months.
Did you encounter any specific issues with your existing Jenkins integration during the migration, or did you have to move to GitHub Actions to get the full benefit of Playwright's trace viewer?
Playwright's native support for mobile emulation and geolocation testing without third-party plugins was the deciding factor for our QA team. It’s much more stable for modern web apps.
I completely agree with Kimberly. The mobile emulation is incredibly accurate. We used to struggle with Appium for simple responsive web checks, but Playwright simplified that entire workflow for us.
To answer your question, Gregory, we actually kept our Jenkins setup. We just had to update our pipeline script to store the Playwright trace files as artifacts. The trace viewer is a godsend for debugging failed headless tests. It allows our developers to see exactly what happened at each step with a full DOM snapshot, which actually reduced our "time-to-fix" for automation bugs by about 50% compared to the old Selenium screenshots and logs we were relying on previously.
