title: Create http.Response instance with sample body string in golang
body: <p>I am willing to create a sample <code>http.Response</code> instance in golang with a sample body string. </p>
  
  <p>Problem is, its body property accepts <code>ReadCloser</code> instance. But as its a dummy response instance, I was wondering if there is some trick to set it easily without setting up all that stream read/close parts.</p>
