But it gives you the option to use a WebDriver, to connect to a headless browser, and mimic a user browsing your website. It gives you some options: Selenium2, ZombieJS and, the easiest to configure, PhantomJS.

This article covers the installation and usage of PhantomJS, and assumes you are using Laravel Homestead, but it will work on any relatively new Debian based distro, like Ubuntu 14.04.

###Install PhantomJS

Node.js core does its best to treat every platform equally. Even if most Node developers use OS X day to day, some use Windows, and most everyone deploys to Linux or Solaris. So it's important to keep your code portable between platforms, whether you're writing a library or an application.

Predictably, most cross-platform issues come from Windows. Things just work differently there! But if you're careful, and follow some simple best practices, your code can run just as well on Windows systems.

Paths and URLs

On Windows, paths are constructed with backslashes instead of forward slashes. So if you do your directory manipulation
