Disclosure: Evinced has paid for my time in writing this blog, and I have provided them feedback on the version of their tool reviewed and an early beta. I agreed to this because I believe in the product they are offering.
Testing your app for accessibility is an essential part of making an accessible app, as with any part of the software you build, if you don’t test it, how can you be sure it works? Because accessibility is human, there are no true shortcuts to this, a through manual test will always be the most productive form of accessibility testing possible. But with some carefully designed automated checks, you can detect common accessibility issues quicker and earlier. This makes fixing them easier, the chance of these errors reaching your customers is reduced, and it saves you valuable time for resolving more complex issues. It’s not an easy problem to solve – I’ve tried with A11yUITests, and Apple built their offering, Accessibility Inspector, right in to Xcode. Now a new tool has entered the arena from Evinced, the iOS Accessibility Debugger.
