title: How to test form request rules in Laravel 5?
body: <p>I created a form request class and defined a bunch of rules. Now I would like to test these rules to see if the behaviour meets our expectations.</p>
  
  <p>How could I write a test to accomplish that?</p>
  
  <p>Many thanks in advance for your answers!</p>
  
  <p><strong>Update</strong>: more precisely, I would like to write a unit test that would check e.g. if a badly formatted email passes validation or not. The problem is that I don't know how to create a new instance of the Request with fake input in it.</p>
