Modern Web Testing and Automation with Puppeteer
summary
Puppeteer is a Node library that automates headless and full Chrome; it downloads a browser on npm install and drives pages, DOM, network and input. It adds Puppeteer Firefox experimental for cross‑browser testing, a BrowserContext API that isolates tests without relaunching the browser (about 100x faster), reactive waitForX APIs to cut flakiness, request interception to mock or abort endpoints, device and geolocation emulation, service‑worker inspection, tracing, coverage, accessibility snapshots, and a growing ecosystem (20% community contributions, 1,000+ packages).
