Testing Web Applications with Playwright
summary
Playwright provides end-to-end, cross‑browser testing with one API and multi‑language support (JavaScript/TypeScript, .NET, Java, Python). Tests run in full isolation and parallel by default, locators auto‑wait and getByRole locators simplify selectors, and codegen records user actions to produce editable tests (recorded a Netflix chat flow and exposed a bug: emails sent without an @). Traces capture DOM snapshots, network and console and open in a trace viewer for step‑by‑step debugging; CI workflow for GitHub Actions and iPhone 12 mobile emulation are built in.
