How can we decide what user personas or disabilities to focus on when testing?
Question
Answer
Aim to include as many different assistive technologies and user needs as is feasible. Even users with the same tool, like a screen reader, can have a very different experiences. The more variety you test for, the more barriers you'll catch.
That's also why WCAG guidelines are so important. They provide a foundation for accessibility across a wide range of disabilities and tech. Start with a solid WCAG audit, then use assistive tech testing to go beyond basic compliance and make sure your product is truly usable.
Testing users with disabilities is great user testing. They often interact with content in unique, detailed ways, surfacing issues others might miss. So don't just focus on screen readers, include a mix of tools and users to get a complete picture.
