The World Wide Web Consortium (W3C) Web Accessibility Initiative (WAI) has announced that the Accessibility Guidelines Working Group (AG WG) and the ACT Task Force have published the Accessibility Conformance Testing (ACT) Rules Format 1.0 as a “W3C Recommendation” web standard.
As stated in the Recommendation Abstract, “The Accessibility Conformance Testing (ACT) Rules Format 1.0 defines a format for writing accessibility test rules. These test rules can be used for developing automated testing tools and manual testing methodologies. It provides a common format that allows any party involved in accessibility testing to document and share their testing procedures in a robust and understandable manner. This enables transparency and harmonization of testing methods, including methods implemented by accessibility test tools.”.
The ACT Rules 1.0 focus on a structure based on Atomic rules which describe how to test a specific type of solution, and Composite rules which describe how the outcomes of multiple Atomic rules can be combined into a single outcome for each test target.
It’s great to see this guidance made available to help provide consistency in the way online content is tested for accessibility.
