Automated Visual Regression and Accessibility Testing Made Easy
summary
Step-by-step recipe for running automated accessibility checks and pixel-by-pixel visual regression using Playwright, containerizing tests with Docker to avoid OS/browser rendering flakiness (Intel vs Apple chips, font aliasing), and wiring results into GitHub Actions so failing PRs upload viewable reports and artifacts. Shows exact failing DOM (missing alt text), how baselines get generated and accepted, pixel-diff screenshots, and a suggested build-artifact optimization to avoid duplicate prod builds.
