Webapp Testing

This is a solid reference for E2E testing with Playwright, focusing on discovery-first auditing where you map routes, scan responses, and test critical paths systematically. It includes a runtime script for automated browser testing with screenshot and accessibility checks built in. The guidance is practical: use the testing pyramid, prioritize happy paths and auth flows, stick to data-testid selectors, and avoid the usual anti-patterns like hardcoded waits. The tables are dense with specifics on configuration, CI setup, and what actually matters in visual and API testing. It's opinionated in the right ways, like being upfront that E2E tests are expensive and should cover critical flows only.
