[DEPRECATED] axe-matchers

This repository has been deprecated. The package has been moved to axe-core-gems. These set of packages will be available via rubygems.org prefixed with @axe-core-* .

Automated accessibility testing powered by aXe.

Provides Cucumber step definitions and RSpec matchers for auditing accessibility.

Uses the aXe core javascript library for accessibility testing.

Philosophy

We believe that automated testing has an important role to play in achieving digital equality and that in order to do that, it must achieve mainstream adoption by professional web developers. That means that the tests must inspire trust, must be fast, must work everywhere and must be available everywhere.

Manifesto

Automated accessibility testing rules must have a zero false positive rate
Automated accessibility testing rules must be lightweight and fast
Automated accessibility testing rules must work in all modern browsers
Automated accessibility testing rules must, themselves, be tested automatically
