title: What is wrong with Stubs for unit testing?
body: <p>I just watched this funny <a href="http://www.youtube.com/watch?v=T-Qn_-F2x1c" rel="noreferrer">YouTube Video about unit testing</a> (it's Hitler with fake subtitles chewing out his team for not doing good unit tests--skip it if you're humor impaired) where stubs get roundly criticized.  But I don't understand what wrong with stubs.</p>
  
  <p>I haven't started using a mocking framework and I haven't started feeling the pain from not using one.</p>
  
  <p>Am I in for a world a hurt sometime down the line, <a href="http://martinfowler.com/articles/mocksArentStubs.html" rel="noreferrer">having chosen handwritten stubs and fakes instead of mocks (like Rhinomock etc)?</a> (using Fowler's taxonomy)</p>
  
  <p>What are the considerations for picking between a mock and handwritten stub?</p>
