title: What's the best way to test mongoid models in rails with tdd/bdd?
body: <p>To test rails/mongoid DB models until now, I used to have a real model with few data (3 .. 5), trying to cover every case for real.</p>
  
  <p>I'm already testing outside in BDD with cucumber, but I usually stop earlier, using rspec very little and without fixture and mockup, prefearing real cases and printing the fields values with rails logger via <code>Rails.logger.info</code> </p>
  
  <p>But now I fed up with that, when the models get more complicated, it's too overwhelming.</p>
  
  <p>What's the best way to test mongoid models in rails with tdd/bdd ?
  Where can I start ? </p>
