Pa11y CI

This is a new project based around Pa11y, named Pa11y CI. Pa11y CI will be a command-line tool which runs Pa11y against multiple URLs. It will be heavily geared towards easily running in CI environments against new versions of websites, but will also be runnable in local development.

Requirements

This command line tool requires Node.js 4+. You can install through npm:

npm install -g pa11y-ci

Usage

Pa11y CI can be used by running it as a command line tool, pa11y-ci:

Usage: pa11y-ci [options]

Options:

  -h, --help           output usage information
  -V, --version        output the version number
  -c, --config <path>  the path to a JSON or JavaScript config file
  -s, --sitemap <url>  the path to a sitemap
  -j, --json           Output results as JSON

Configuration

By default, Pa11y CI looks for a config file in the current working directory, named .pa11yci. This should be a JSON file.

You can use the --config command line argument to specify a different file, which can be either JSON or JavaScript. The config files should look like this:

{
    "urls": [
        "http://pa11y.org/",
        "http://pa11y.org/contributing"
    ]
}

Pa11y will be run against each of the URLs in the urls array.

Default configuration

You can specify a default set of pa11y configurations that should be used for each test run. These should be added to a default object in your config. For example:

{
    "defaults": {
        "timeout": 1000,
        "page": {
            "viewport": {
                "width": 320,
                "height": 480
            }
        }
    },
    "urls": [
        "http://pa11y.org/",
        "http://pa11y.org/contributing"
    ]
}

Pa11y CI has a few of its own configurations which you can set as well:

• concurrency: The number of tests that should be run in parallel. Defaults to 2.

URL configuration

Each URL in your config file can be an object and specify pa11y configurations which override the defaults too. You do this by using an object instead of a string, and providing the URL as a url property on that object. This can be useful if you know that a certain URL takes a while to load, for example:

{
    "defaults": {
        "timeout": 1000
    },
    "urls": [
        "http://pa11y.org/",
        {
            "url": "http://pa11y.org/contributing",
            "timeout": 50000
        }
    ]
}

Sitemaps

If you don't wish to specify your URLs in a config file, you can use an XML sitemap that's published somewhere online. This is done with the --sitemap option:

pa11y-ci --sitemap http://pa11y.org/sitemap.xml

This takes the text content of each <loc> in the XML and runs Pa11y against that URL. This can also be combined with a config file, but URLs in the Sitemap will override any found in your JSON config.

Contributing

To contribute to Pa11y CI, clone this repo locally and commit your code on a new branch.

Please write unit tests for your code, and check that everything works by running the following before opening a PR:

make ci

You can also run verifications and tests individually:

make verify              # Verify all of the code (JSHint/JSCS)
make test                # Run all tests
make test-unit           # Run the unit tests
make test-unit-coverage  # Run the unit tests with coverage
make test-integration    # Run the integration tests
