/**
 * Trait MailTracking
 *
 * Trait to mixin to your test to allow for custom assertions when using PHPUnit with Laravel. This trait assumes
 * you are using it from the PHPUnit TestCase class (or a child class of it).
 *
 * This originally started out as a copy & paste from a video series that Jeffrey Way did on laracasts.com. If you do
 * not have an account on Laracasts, you should get one. It is an amazing resource to learn from. We used that
 * example & converted it to a package so that it would be easy to install. We have also expanded on the initial
 * assertions.
 *
 * I WANT IT CLEAR THAT THIS WOULD NOT HAVE HAPPENED WITHOUT THE INITIAL WORK OF JEFFREY WAY. WE ARE NOT CLAIMING TO
 * BE THE CREATORS OF THE CONCEPT.
 *
 * @package Spinen\MailAssertions
 * @see     https://gist.github.com/JeffreyWay/b501c53d958b07b8a332
 * @tutorial https://laracasts.com/series/phpunit-testing-in-laravel/episodes/12
