📝 About Playwright
Playwright ended the era of flaky end-to-end tests. Built at Microsoft by the original Puppeteer team, it drives all major browser engines with one API, auto-waits for elements before acting, and runs tests in parallel out of the box. Tests that used to fail randomly at 3 a.m. now actually catch regressions.
Developer experience is where it pulls ahead. Codegen records browser interactions into test code, the trace viewer lets you step through a failure frame by frame with network and console detail, and fixtures make patterns like authenticated sessions reusable. Mobile emulation, network interception, and visual comparison cover the rest of the checklist.
In 2026 Playwright is the default choice for web E2E testing, with AI agents even using it to verify their own generated code. Cypress still has fans, but for new projects the community consensus has clearly shifted.
