Playwright

Playwright controls browsers programmatically to simulate user interactions, clicks, form fills, navigation, with built-in auto-waiting for elements and network idle states. It supports parallel test execution, trace recording, and visual regression snapshots.

Codeaxes uses Playwright as the primary E2E tool for Next.js and React products because it runs consistently in CI, supports multiple browsers from one API, and produces trace files that make flaky test diagnosis straightforward.
