As is often the case, when it comes to accessibility, sometimes we learn what is needed, and then we look for a tool. Other times, learning to use a tool can help us understand better the underlying requirements. Much like a spell-checker, it can tell you that words are misspelled, and offer suggestions for spelling them correctly, but it won’t teach you the rules of grammar needed to confirm the corrections are in context or appropriate for that moment. this session is going to attempt to do a little bit of both. It’s meant to be an introduction to Accessibility Testing, using a specific tool in the process.
We will be using AChecker. Why? It’s an open source evaluation tool that lets users submit web pages via URL, direct file upload and also pasting snippets of HTML into a window. With this, you can evaluate a full page or something as small as a few lines of HTML. It also has a god range of standards to compare with (HTML Validator, BITV, Section 508 , Stanca Act, WCAG 1.0 and WCAG 2.0.
During the session, we had some interesting observations about what the tool showed and the varying levels of context it provided. A nice touch was that in many instances it actually stated what the required values for conformance were, such as (with https://www.google.com):
Success Criteria 1.4.3 Contrast (Minimum) (AA)
