Discover how we tackled the common challenges of a large E2E test suite and made our React codebase easier to refactor.
In the past year, we went from zero to 20,000 lines of Playwright tests, pushing its capabilities beyond basic end-to-end testing. This talk will explore the challenges we encountered as we scaled our Playwright setup and how we solved them, thanks to the robust ecosystem and team creativity.
The talk covers:
- Testing approaches and where common tools fit on the testing pyramid
- Challenges scaling E2E test suites: performance, flakiness, ownership, mocking and more
- How we solved these challenges to unblock refactoring a large React codebase
- Advanced Playwright tips and tricks
This talk has been presented at React Summit 2025, check out the latest edition of this React Conference.
