title: Configure & use mongodb mockup server for unit testing
body: <p>I have to develop some Junit tests for Java code using a MongoDB store. Is there any framework/library which permits me initializing a mock in-memory MongoDB server?</p>
  
  <p>(The idea is to test only the code itself, that means, in any machine independently on if MongoDB is installed &amp; running).</p>
  
  <p>Thanks in advance!</p>
