Documentation / Axe


Axe is an accessibility testing engine for websites and other HTML-based user interfaces.

Run #

You enable testing with --axe.enable.

docker run --rm -v "$(pwd):/" sitespeedio/ --axe.enable

That will run axe-core and generate a new axe tab in your HTML result. The number of violations (per type) will automatically be sent to Graphite/InfluxDB.

Rules #

See the full list of the tested accessibility rules when you run Axe.

Configure Axe #

You can configure Axe which rules/checks that will be used. In the axe namespace we pass on all parameters to the configuration object of Axe. --axe.checks will result in a configuration object like:

checks: {


If you wanna avoid having over complicated cli-params you should use the configuration as JSON feature.

How it works behind the scene #

The Axe tests are run as a postScript.

Running Axe will add some extra run time per test. How long extra time it takes depends on your page and the server running the browser.
