Playwright

End-to-End (E2E) Testing · Open Source (Apache-2.0)

Reliable cross-browser E2E tests with powerful auto-waiting, tracing, and test isolation. Works well in CI with parallelization and flakes control.

We use Playwright for user-journey and regression tests, plus accessibility assertions and visual comparisons when needed.

How We Use It

  • Cross-browser end-to-end testing
  • Visual regression testing with screenshots
  • Automated user journey validation

Monitoring & Testing

Why this matters: Observability and tests catch regressions early, reduce MTTR, and enable confident, frequent releases. We ship with confidence by instrumenting apps end-to-end: unit and integration tests, accessibility checks, and production observability. Our approach emphasizes fast feedback loops, clear failure signals, and actionable telemetry. Preferred defaults: Sentry for errors/perf, Playwright for E2E, Vitest or Bun Test for unit, OpenTelemetry for tracing, Lighthouse CI for budgets.
