- * ### PhantomJS
- *
- * PhantomJS is a [headless browser](https://en.wikipedia.org/wiki/Headless_browser) alternative to Selenium Server that implements
- * [the WebDriver protocol](https://code.google.com/p/selenium/wiki/JsonWireProtocol).
- * It allows you to run Selenium tests on a server without a GUI installed.
- *
- * 1. Download [PhantomJS](http://phantomjs.org/download.html)
- * 2. Run PhantomJS in WebDriver mode: `phantomjs --webdriver=4444`
- * 3. Configure this module (in `acceptance.suite.yml`) by setting url and `phantomjs` as browser:
- *
- * ```yaml
- *     modules:
- *        enabled:
- *           - WebDriver:
- *              url: 'http://localhost/'
- *              browser: phantomjs
- * ```
- *
- * Since PhantomJS doesn't give you any visual feedback, it's probably a good idea to install [Codeception\Extension\Recorder](http://codeception.com/extensions#CodeceptionExtensionRecorder) which gives you screenshots of how PhantomJS "sees" your pages.

  * ### Headless Selenium in Docker
  *
  * Docker can ship Selenium Server with all its dependencies and browsers inside a single container.
