Why Playwright:

Cross-browser. Playwright supports all modern rendering engines including Chromium, WebKit, and Firefox.

Cross-platform. Test on Windows, Linux, and macOS, locally or on CI, headless or headed.

Auto-wait. Playwright waits for elements to be actionable prior to performing actions. It also has a rich set of introspection events. The combination of the two eliminates the need for artificial timeouts - the primary cause of flaky tests.

Web-first assertions. Playwright assertions are created specifically for the dynamic web. Checks are automatically retried until the necessary conditions are met.

Tracing. Configure test retry strategy, capture execution trace, videos, screenshots to eliminate flakes.

Test frames, pierce Shadow DOM. Playwright selectors pierce shadow DOM and allow entering frames seamlessly.

Browser contexts. Playwright creates a browser context for each test. Browser context is equivalent to a brand new browser profile. This delivers full test isolation with zero overhead. Creating a new browser context only takes a handful of milliseconds.

Log in once. Save the authentication state of the context and reuse it in all the tests. This bypasses repetitive log-in operations in each test, yet delivers full isolation of independent tests.
