title: Request is not executed during mocha integration test
body: <p>Before exchanging an API, I want to secure the client (which uses the API)  with integration tests to make sure that the new API delivers the same results as the old one and the client still works as expected. Therefor I have written several integration tests for the respective client methods. These client methods use <strong>request</strong> to query the API.<br>
  I am then using mocha to execute the tests. Within the tests it now seems like the requests are not executed at all.  </p>
  
  <p>I have made a simple example to show my problem:  </p>
  
  <pre><code>var request = require('request');
  var assert = require('chai').assert;
  
  describe('test', function(){
      it('request-test', function(done){
          var responseBody;
          request('http://www.google.com', function (error, response, body) {
              if (!error &amp;&amp; response.statusCode == 200) {
                  console.log(body) 
                  responseBody = body;    
              }                   
          });
          done();
          assert.notEqual(responseBody, undefined);
      });
  }); 
  </code></pre>
  
  <p>In this example the console.log is never executed and the test always fails in the assertion. </p>
