title: PHPUnit Class "Error" does not extend PHPUnit_Framework_TestCase
body: <p>I am using Laravel 4.2 with PHP 5.6.  I did a composer update and now when I run my unit tests, I get the error <code>Uncaught PHPUnit_Framework_Exception: Class "Error" does not extend PHPUnit_Framework_TestCase</code>.  I don't know for sure, but I believe my laravel version went from 4.2.19 to 4.2.22</p>
  
  <p>How do I get my unit tests to work?</p>
