    NAV-ally

    What is this

    An automation tool for testing frontend applications against a set of web accessibility guidelines (WCAG 2 (A, AA, AAA), Section 508 etc).

    The tool can be a part of a build pipeline, but can also be used standalone to test any frontend application. You create a list of links in a definition file that can be either a plain Yaml configuration or a Javascript based configuration. The tool supports preprocessing of the web sites before validation with an DSL built on top of Selenium Webdriver (ie. clicking a button to load additional data). It uses Axe under the hood to preform the actual web accessibility validation.

    Quick start

    You must have ChromeDriver installed and set in the path, before starting. On MacOS/Linux, you can do that easily with Brew:

    1. $ brew cask install chromedriver

      If you are planning to integrate with Jenkins, read about the Docker-setup here.

      If you need to install ChromeDriver manually on Linux, see this Docker file.

    2. Add the module to your project

      npm install --save-dev nav-ally

    3. Create a Yaml-based definition file and add it anywhere in your project:

      $ touch wcag.yml
      $ nano wcag.yml
      

      Paste in the following example content:

      links:
       - "http://google.com"
    4. Create a run script in your package.json:

      "wcag-test":"nav-ally -f wcag.yml"

      See more command line arguments in the documentation

    5. You can now run the validator:

      $ npm run wcag-test

    See this example application for a complete NodeJS/Express application that uses the validator. The example application starts a local instance of the application before running the validation.
