When we develop a new web application, we often put a lot of work on the design, on making it beautiful and usable. In other words, we want our web app to be effective, efficient, and satisfying for the user. But a lot of times we don’t think about the user experience for people with disabilities, including people with age-related impairments. Automated web a11y tests can free up our QA team from manual testing every part of our application, but they can’t automatically make our site accessible. We should use automated a11y tests as one step of a larger testing process, including manual tests.
