3. Automated Accessibility Testing Tool (AATT)

Browser-based accessibility testing tools and plugins require manually testing each page, one at a time. Tools that can crawl a website can only scan pages that do not require login credentials, and that are not behind a firewall. Instead of developing, testing, and using a separate accessibility test suite, you can now integrate accessibility testing into your existing automation test suite using AATT.

4. Tanaguru

Tanaguru is an open source (AGPL license) website assessment tool. It is dedicated to accessibility (a11y) audits, and focuses on reliability and high level
of automation.

5. Quail

QUAIL is a jQuery plugin for checking content against accessibility guidelines. It provides a flexible way to test for certain problems (say, images missing
an alt text) and a collection of over 200 tests to get you started. Defining your tests is easy, and you can pick-and-choose tests to focus on the needs of your app.
