Automated Accessibility Testing

" summary

Claim: common automated tools (axe, Lighthouse, Pa11y/HTML_CodeSniffer, Accessibility Insights) catch only about 20–30% coverage of WCAG failures (axe advertises ~57% while experts report 0–13.5%). Demonstrations use a React example app with unit and end-to-end tests (vitest/Jest style, testing-library, Playwright) that add specific checks: a keyboard navigation test (Tab focus order), role assertions via aria semantics, and a layout check by setting font-size 200% and comparing clientHeight vs scrollHeight. AI can generate tests and help recognize visuals but cannot fully auto‑fix context‑dependent accessibility.
