title: How to assert/unit-test servers JSON response?
body: <p>My current project uses JSON as data interchange format. Both Front-end and Back-end team agree upon a JSON structure before start integrating a service. At times due to un-notified changes in JSON structure by back-end team; it breaks the front-end code.</p>
  
  <p>Is there any external library that we could use to compare a mock JSON (fixture) with servers JSON response. Basically it should assert the whole JSON object and should throw an error if there is any violation in servers JSON format.</p>
  
  <p>Additional info: App is built on JQuery consuming REST JSON services.</p>
