title: When/How to Unit Test CRUD applications?
body: <p>I've been hearing alot about unit testing lately.</p>
  
  <p>What I'm trying to understand is how would one / should one go about unit testing a cruddy business app? (basically an app that writes data in / reads data out of a database).</p>
  
  <p>Is unit testing even worth it in that scenerio or do you usually unit test more complicated things?</p>
  
  <p>Thanks</p>
