Grunt plugin for aXe utilizing WebDriverJS

Getting Started

This plugin requires Grunt ~0.4.5

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-axe-webdriver --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-axe-webdriver');

In your project's Gruntfile, add a section named axe-webdriver to the data object passed into grunt.initConfig().

      options: {

Usage Examples

Default Options

In this example, the default options are used in combination with a list of two URLs that are to be tested for accessibility issues. The accessibility tests wil be run in Firefox only. The results will not be output but will be tested for zero violations. If violations occur, the Grunt task will fail and interrupt the Grunt script.

grunt.initConfig({
  "axe-webdriver": {
    firefox: {
      options: {},
      urls: ['http://localhost:9876/tests/test1.html', 'http://localhost:9876/tests/test2.html']
    }
  },
});

Additional browser

In this example, the custom target browser option is used to add tests for the Chrome browser. Note that the urls for each target must be supplied. This also means that the urls can be different for each browser.

grunt.initConfig({
  "axe-webdriver": {
    firefox: {
      options: {},
      urls: ['http://localhost:9876/tests/test1.html', 'http://localhost:9876/tests/test2.html']
    },
    chrome: {
      options: {
        browser: "chrome"
      },
      urls: ['http://localhost:9876/tests/test1.html', 'http://localhost:9876/tests/test2.html'],
    }
  },
});

Tag filtering

Single

In this example, the only violations that will be checked for are those that have the matching tag.

grunt.initConfig({
  "axe-webdriver": {
    firefox: {
      options: {
        tags: 'wcag2a'
      },
      urls: ['http://localhost:9876/tests/test1.html', 'http://localhost:9876/tests/test2.html']
    }
  }
});
Multiple

In this example, the only violations that will be checked for are those that have one of the matching tags.

grunt.initConfig({
  "axe-webdriver": {
    firefox: {
      options: {
        tags: ['wcag2a', 'wcag2aa']
      },
      urls: ['http://localhost:9876/tests/test1.html', 'http://localhost:9876/tests/test2.html']
    }
  }
});
