Test automation is evolving rapidly. Recently, we decided to migrate our massive Katalon test suite to Playwright to improve our CI/CD pipeline's reliability and execution speed. Katalon had served us well, but as our application grew in complexity, we began facing flakiness and high resource consumption during parallel runs.
Why Playwright?
Playwright offers built-in auto-waiting, a fantastic tracing viewer, and seamless cross-browser testing. Its ability to intercept network requests natively gave us the power to mock heavy third-party APIs, drastically reducing test execution time from 45 minutes to just under 8 minutes.
The migration wasn't without challenges. Rewriting thousands of Groovy scripts into TypeScript required a solid design pattern. We adopted the Page Object Model (POM) and implemented custom fixtures. This guide details our exact roadmap, from proof-of-concept to full deployment.
