title: How to specify a different .env file for phpunit in Laravel 5?
body: <p>I have a <code>.env</code> file containing my database connection details, as is normal for Laravel 5. I want to override these for testing, which I can do in <code>phpunit.xml</code>. However, doing this seems to go against the philosophy of <code>.env</code> which is not to commit environmental configurations, particularly passwords.</p>
  
  <p>Is it possible to have something like <code>.env.testing</code> and tell <code>phpunit.xml</code> to read from that?</p>
