title: Testing REST web service client when the services don't yet exist
body: <p>I have already read the posts <a href="https://stackoverflow.com/questions/203495/testing-rest-webservices" title="here">link text</a> and <a href="https://stackoverflow.com/questions/303911/rest-tools-support-for-development-and-testing" title="here">link text</a> but these are covering the use case of building a REST service on the server and requiring a rapid client in order to test those services.</p>
  
  <p>We have the opposite problem, we are building a web client that will communicate to the server via REST, but the decision has been taken to let the client drive the format of the services on the server, this means the client is being implemented first and the services on the server second.</p>
  
  <p>I am trying to look for a tool which would allow me to very quickly knock up REST web services, which the client could then be tested against. Effectively mocking the server.</p>
  
  <p>Does anyone know of such a tool? </p>
