title: Disable render when testing a controller
body: <p>I'm using Test::Unit with shoulda to test a controller.</p>
  
  <p>Since I'm just testing the controller I dont wanna the view to be rendered.</p>
  
  <p>I'm stubbing some objects, some errors are throw when the view is rendered, but the test shouldn't fail, because the controller is correct.</p>
  
  <p>So, theres any way to disable the rendering of a template/view, from my tests?</p>
  
  <p>I heard that rSpec works like that.</p>
