The Accessibility Guidelines Working Group has published a First Public Working Draft of Accessibility Conformance Testing (ACT) Rules Format 1.1, which 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.
