title: Camel: junit-test of processor via intercept
body: <p>Sorry, if I miss the forest for the trees...</p>
  
  <p>We would like to junit-test some Java-DSL. We found some way to do this on our original routes and not with copied ones.
  Using i.e. <code>expectedMessageCount()</code> and <code>assertIsSatisfied()</code> works well for endpoints 'made with <code>to()</code>'.</p>
  
  <p>Now I am searching for a way to intercept a processor (<code>DSL process(new Processor() {...}</code>) using intercept or better interceptSendToEndpoint, but that one has no URI. Is there a way to do this.</p>
