Automation and taking full-screen screenshots using Laravel Dusk and Chrome webdriver

screenshot.php

<?php

    /**
    * This script is using Laravel Dusk to take screenshots of a URL, but not in the context of a regular Dusk test.
    * My Laravel application is taking screenshots of *other* sites, but you could adapt this to a Dusk test taking screenshots of your Laravel site.
    * 1. Install Dusk https://laravel.com/docs/5.8/dusk#installation
    * 2. Make sure it works with regular Dusk tests first.
    * 3. Use the code below for a stand-alone Chrome webdriver instance to do automation things.
