Making behat use phantomjs for the tests

If you want to run it on phantomjs (a headless browser) you can add this profile to your behat.yml and you need phantomjs >= 1.8.0

phantomjs:
    extensions:
        Behat\MinkExtension\Extension:
            base_url: http://dev.local
            goutte: ~
            selenium2:
                wd_host: "http://localhost:8643/wd/hub" 

    formatter:
        name:               pretty,html
        parameters:
            output_path:    null,jm_behat_report.html

start up the phantomjs web driver using: $ phantomjs --webdriver=8643

then run using:

$ ./bin/behat -p phantomjs

Note: You don't need to have selenium running as it communicates directly with the webdriver server that phantomjs/ghostdriver starts

Note2: apparently there is also a way to have it run by registering with a selenium hub and requesting the browserName 'phantomjs' but I couldn't get it to work, see https://github.com/detro/ghostdriver#register-ghostdriver-with-a-selenium-grid-hub or the copied instructions below

1. Launch the grid server, which listens on 4444 by default: java -jar /path/to/selenium-server-standalone-2.25.0.jar -role hub
2. Register with the hub: phantomjs --webdriver=8080 --webdriver-selenium-grid-hub=http://127.0.0.1:4444
3. Now you can use your normal webdriver client with http://127.0.0.1:4444 and just request browserName: phantomjs
