patternfly-a11y

This is a CLI tool developed for patternfly-react, patternfly-next, and patternfly-org to run axe in Selenium on a list of urls. It has options suited to our needs but should work as an integration test for any project.

It outputs a coverage directory with:

  • report.json: full axe output per-url
  • report.xml: junit coverage grouped into test cases
  • report.html: more readable html report of report.xml
  • dist: contains the webpack output for the full a11y report

Usage

patternfly-a11y [command]

patternfly-a11y --help

Commands:
  patternfly-a11y <file>  Audit a list of URLs in JSON file

Options:
  -V, --version                output the version number
  -c, --config <file>          Path to config file
  -p, --prefix <prefix>        Prefix for listed urls (like https://localhost:9000)
  -cr, --crawl                 Whether to crawl URLs for more URLs (default: false)
  --no-code-on-fail            By default, exit code 1 is returned on test failures, and 2 if there are incomplete tests, this disables that
  -s, --skip <regex>           Regex of pages to skip
  -a, --aggregate              Whether to aggregate tests by component (by splitting URL) in XML report (default: false)
  --no-screenshots             Whether to save screenshots of visited pages
  -ir, --ignore-rules <rules>  Axe: Comma-separated list of error ids to ignore (default: "color-contrast")
  -iI, --ignore-incomplete     Axe: Whether to ignore incomplete errors (default: false)
  -t, --tags <tags>            Axe: Comma-separated list of accessibility (WCAG) tags to run against (default: "wcag2a,wcag2aa")
  -ctx, --context <context>    Axe: Context to run in, defaults to document, can be set to a different selector, i.e. document.getElementById("content")
                               (default: "document")
  --no-pf-report               Whether to build out the full PatternFly a11y report into coverage/dist
  -h, --help                   display help for command

Getting started

npm i @patternfly/patternfly-a11y

then

node_modules/.bin/patternfly-a11y [json-list-of-urls]

OR

node_modules/.bin/patternfly-a11y --prefix http://localhost:9000 --crawl /dashboard

For more advanced usage, you can create a config file

node_modules/.bin/patternfly-a11y --config a11y-config.js

Sample configuration file (a11y-config.js)

/**
* page: pupeteer page object, for more information see
* https://pptr.dev/#?product=Puppeteer&version=v3.3.0&show=api-class-page
*
* data: contains the options passed in
*/
async function login({ page, data }) {
  const user = "user";
  const pass = "pass";
  await page.waitForSelector("#inputUsername");
  await page.type("#inputUsername", user);
  await page.type("#inputPassword", pass);
  await page.click("button.pf-c-button");
  await page.waitForNavigation();
  await delay(1000);
}
/**
* page: pupeteer page object, for more information see
* https://pptr.dev/#?product=Puppeteer&version=v3.3.0&show=api-class-page
*/
async function waitForSpinner(page) {
  // there should be no loading spinner
  await page.waitForSelector(".loading-spinner", {
    hidden: true,
  });
}
module.exports = {
  // the root of the URLs to test
  prefix: "https://my-website.com",
  // If you need to authenticate/login you can specify a function here
  auth: login,
  // if there are common elements to wait for on pages to test can specify here
  waitFor: waitForSpinner,
  // if you want axe to only test a subset of the document you can specify it here, defaults to the entire document
  context: 'document.getElementById("page")',
  // we define our own list of URLs to test
  crawl: false,
  // urls can contain strings or objects for more control
  urls: [
    "/dashboards",
    {
      url: "/projects",
      label: "projects page",
      afterNav: async (page) => {
        // pupeteer page object, for more information see
        // https://pptr.dev/#?product=Puppeteer&version=v3.3.0&show=api-class-page
        await page.waitForSelector(".some-element-to-wait-for");
      },
    },
    "/k8s/cluster/projects/default",
    "/search/ns/default",
    "/api-explorer"
  ],
};

As a global package

You can install patternfly-a11y as a global package to build out a report anywhere. Because the full patternfly-a11y report uses components that have a peer dependency on react, you can either install these (react,react-dom) globally as well or install its peer dependencies using the install-peerdeps package.

# easier way
yarn global add @patternfly/patternfly-a11y react react-dom

# slightly more involved way
yarn global add @patternfly/patternfly-a11y install-peerdeps
cd `yarn global dir`
cd `yarn global dir`/node_modules/@patternfly
install-peerdeps @patternfly/react-core

# now you can use the command from anywhere, the coverage folder will be created in your present working directory
cd ~
patternfly-a11y --no-code-on-fail https://pf4.patternfly.org/components/alert

Viewing the full accessibility report

After running the patternfly-a11y command, a coverage folder was created. In it the full report will be bundled in the dist folder. You can open up the index.html file directly to view the report. You can also run a local webserver and/or upload the report. Example:

# Run local webserver
yarn global add serve
serve coverage/dist

# Upload the report
yarn global add surge
cd coverage/dist
surge
