title: Android + Espresso + async HTTP request -> how to test?
body: <p>i'm trying to test Android app using Espresso FW and I stucked on the problem with doing async HTTP request. </p>
  
  <p>How can i test the case that app (activity) is waiting for processing request and after the response is received is displayed next activity with result or error message? </p>
  
  <p>I tried to find any solution how to do it in the Espresso with testing against the data from the test server, but without luck.</p>
  
  <p>Many thanks for any advice, example or link. </p>
