1. Aspects of Web Accessibility Auditing
Though in many cases using automated and manual testing strategies is sufficient to identify and address potential accessibility issues, it can be helpful to have users with disabilities, or others such as older users, use a site in addition to the other auditing strategies. Actual users can turn up a variety of potential usability issues.
Depending on the audience a site serves, user testers might include a few different people with different accessibility needs, such as a person who is blind using a screen reader, a person with low vision using a magnifier, or perhaps a person with motor impairments using speech recognition and switches to navigate through web content.
User testing will be covered in depth in the chapter User Testing.
