QA + Testing
End-to-end, integration, visual regression, and performance gates.
A real test pyramid for the things that actually break in production. Playwright suites for critical flows, Vitest / Jest coverage on the layers that matter, visual regression to catch silent UI drift, k6 load tests with perf budgets, and a11y QA on the running app.
What you get
4 pillarsE2E with Playwright
Critical-flow Playwright suites wired into CI — deploys block on broken flows, not on lint nits.
Coverage where it counts
Vitest / Jest unit + integration coverage on business logic, not on glue code, aiming at the 80% line where it matters.
Visual regression
Chromatic / Percy visual snapshots to catch unintended UI changes before a designer or customer notices.
Perf + a11y gates
k6 / Artillery load tests, Lighthouse CI budgets, Axe + manual a11y testing on the live app.

Frequently asked
4 questionsPlaywright or Cypress for E2E testing?
Playwright by default — better parallelism, multi-browser support out of the box (Chromium, Firefox, WebKit), and a simpler async model. Cypress when an existing suite already uses it. Either way, tests run in CI on every PR.
How does testing integrate with CI?
GitHub Actions or Vercel CI runs unit, integration, and E2E suites on every PR. Coverage thresholds gate merges. Flaky tests get quarantined automatically and surfaced on a dashboard, not silently retried until green.
Performance and load testing?
Lighthouse CI for per-PR Core Web Vitals budgets — fails the build if LCP, INP, or CLS regress. k6 for load and stress testing on API endpoints. Real-user monitoring via Vercel Analytics or Sentry for production truth.
Visual regression and accessibility testing?
Chromatic for visual regression — every component snapshot diffed on PR. Axe for automated accessibility audits in CI. Manual screen-reader passes on critical flows before launch. Catches issues that automation alone misses.
