Crafting a Bulletproof testing pipeline for React Apps
summary
Builds a multi‑layer pipeline that actually ships: unit tests with Jest and React Testing Library, component/visual checks in Storybook with Chromatic and interaction tests, end‑to‑end flows with Playwright (including page.metrics for lightweight perf), and SLO‑driven load tests with k6 pushed into Grafana. Shows code demos, CI gates, mock strategies (MSW), real case studies about surprising failure counts and how much CI time shrinks when tests move down the pyramid, and concrete observability dashboards that proved fixes worked.
