@calumryan Before the implementation, we already assess what WCAG implications / requirements a user story has. If we reuse existing patterns, I usually won't do a full test myself. But we do have dedicated accessibility testers. If there's a new pattern, I will look up the WAI-ARIA Authoring Practices and test the implementation.

I follow a similar route in my personal projects, but I also wrote (and run) a tool for automated a11y checks: https://darekkay.com/evaluatory/
