ARIA and Assistive Technologies (ARIA-AT)

This repository maintains a test suite and harness for assessing assistive technology (AT) support of ARIA. This project is managed by the ARIA-AT Community Group in coordination with the Authoring Practices Task Force of the ARIA Working Group. The W3C staff contact is Daniel Montalvo.

Scope and Method

The initial scope of this test suite is manual testing of a select set of desktop screen readers. Tests are written as assertions of expected screen reader behavior when using example implementations of design patterns in the ARIA Authoring Practices Guide.
