QUAIL 2 is coming
QUAIL is moving to a new home on GitHub where version 2 will be coming soon with a much smaller codebase, more useful tests, and a port to jQuery.
QUAIL is a PHP library that lets you easily check HTML for adherence to accessibility standards. It comes with over 200 tests which implement Open Accessibility Checks and comes with WCAG 1.0, WCAG 2.0, and Section 508 guidelines.
Developers can build their own guidelines, or easily build a custom guideline that integrates with a database back-end or CMS. While the project supports checking entire HTML pages, integration with a CMS to check partial HTML content is probably the most popular use case.

Requirements
QUAIL requires the following:
- PHP 5
- PHP DOMDocument
- PHP Mbstring
Automated Testing vs. Good Practice
No automated tests can replace good practice and a human interpretation of an interface. QUAIL can often point people in the right direction, or point out potential failures, but there can be no replacement for adequate training in web accessibility standards.
The Accessible Helper plugin helps content authors understand what accessibility problems exist on a page, and what they can do to fix those errors. It keeps track in metdata of posts how many errors exist for that post, and can show a list of all errors, or a highlighted version of the post with errors outlined and prefixed with help icons.
