Ember chromium is an easy way to download chromium in your project and run your unit/integration tests through it. It will also run headless by default on CI servers.

1. Install ember-chromium as a dev dependency via npm/yarn

   $ npm install ember-chromium --save-dev
   # -or-
   $ yarn add ember-chromium --dev

2. In your package.json, add a pretest script to run the install-chromium script.

   "scripts": {
     // ...
     "pretest": "npm run install-chromium",
     // -or-
     "pretest": "yarn run install-chromium",
   }

   [Note:] When installed, ember-chromium links the install-chromium script into <project-root>/node-modules/.bin. This directory is on the npm/yarn script path and can be called directly.

You can run just the default behavior by doing the following in testem.js:

module.exports = require('ember-chromium').getTestemConfig();

That's it!

You can further customize the chromium as follows:

const chromium = require('ember-chromium');
const myCustomReporter = require('some-test-reporter');

// any chromium flags you want
const chromiumArgs = [
  '--disable-gpu',
  '--no-sandbox',
  '--disable-gesture-requirement-for-media-playback',
  '--allow-file-access',
  '--use-fake-device-for-media-stream',
  '--use-fake-ui-for-media-stream'
];

const config = chromium.getTestemConfig(chromiumArgs);
config.reporter = myCustomReporter;

module.export = config;

Once you have the default config, you can manipulate as fits your needs.
