wdio-axe

aXe is the accessibility engine for automated testing of HTML-based user interfaces. These hints run the recommended set of WCAG 2.1 Level A and Level AA rules from axe-core.

This module uses axe-core API to inject, configure and analyze web pages rendered by wdio by providing sync bindings.

What does the wdio-axe check?

By default, wdio-axe runs against all the WCAG 2.1 Level A and Level AA rules included in axe-core with document as the target.

These rules are grouped based on their assigned category within axe-core.

Getting started

First download the package:

npm install wdio-axe --save-dev
