ACT Now: Accessibility Conformance Testing for WCAGWILCO FIERS, MARY JO MUELLERW3C STAFF CONTACT: SHADI ABOU-ZAHRA
About the ACT Task Force• Task force under Accessibility Guidelines WG• Facilitators:
Wilco Fiers – Deque @wilcofiers
Mary Jo Mueller – IBM @1mjmueller
•W3C Staff Contact:
Shadi Abou-Zahra – W3C @sabouzah
What is ACT About?• Reduce differing interpretations of WCAG• Make test procedures interchangeable• Develop a library of commonly accepted rules for WCAG
Who is participating?• Tool vendors• Accessibility auditors• You?
What are we doing?• Develop the ACT Framework • Standardize how to write rules, using the ACT Framework• Create a repository of ACT rules

So what are rules? Rules are "general purpose" accessibility tests
Meaning, they aren’t tests for one application; rather, they
can be used on any web page of a particular technology.
Rules can be:• Fully automated tests• Semi-automated / user assisted tests• Manual Test processes
Basically… Rules are to accessibility testing, what WCAG techniques are to development.
An example: Selector: img:not(alt) Test case: if the img does not have `role=presentation`, return `failed`, otherwise return `passed`.
Using rules to test for conformance Multiple rules are then combined to test for WCAG Success Criterion conformance.
Benefits•Harmonized testing
•Transparency
•Better accessibility tools
Reduce interpretation difference By giving testers a step by step method for testing, we reduce interpretation difference. Separating opinion, from test method.
Make accessibility testing transparent By documenting how an organization tests, it becomes much clearer why results are what they are. By defining how tests are done, differences in findings can be explained.
Stimulate innovation in accessibility test tools By having a common set of rules many ATTs use, we stop reinventing the wheel, and have clearer results for anyone looking to compare. This benefits all users.
How will we accomplish this?•ACT Framework (W3C Recommendation)•ACT Rules repository
ACT Framework (W3C Recommendation) A specification for writing ACT rules including such things as:•How do you ensure accuracy•How to ensure it is useful for developers and QA persons•Allow for accessibility support
ACT Rules repository A collection of rules, vetted for accuracy and correctness with WCAG.
