Making Accessibility Testing Suck Less: An Intro to Pa11y
summary
Pa11y scans pages and returns concrete accessibility failures you can act on — CLI runs against URLs, the JavaScript API lets scripts click, wait for elements, set cookies and take screenshots, and custom reporters emit HTML/JSON/CSV. Use the ignore and standard flags, feed a sitemap or list of pages, and set threshold-based failures to break CI (example run finds 39 issues or six errors on the home page). Pa11y does not fix issues; it finds and documents them for developers.
