I am one of the maintainers of the axe accessibility testing engine the Slack team is using. It's awesome to see such a detailed writeup of how folks are building on our team's work!<p>We publish the engine (axe-core) and the "core" playwright integration library Slack is using (@axe-core/playwright) as open source, but if you're interested in what the Slack team has described in this blog, we also have a paid offering called axe Developer Hub (<a href="https://www.deque.com/axe/developer-hub" rel="nofollow">https://www.deque.com/axe/developer-hub</a>) that offers a similar workflow to what the Slack folks describe here: It hooks into end-to-end tests you already have to add in accessibility testing without needing a ton of code changes to your test suite.<p>It's very enlightening to see which features the Slack folks prioritized for their setup and to see some of the stuff they were able to do by going deep on integration with Playwright specifically. It's not often you are lucky enough to get feedback as strong as "we cared about <feature> enough to invest a bunch of engineering time into it".<p>If you're interested in building these sort of accessibility tools, my team is hiring! <a href="https://www.deque.com/careers/senior-accessibility-tool-developer" rel="nofollow">https://www.deque.com/careers/senior-accessibility-tool-deve...</a>
