title: REST API testing common issues
body: <p>I have recently started testing rest based web services. I am wondering what are common issues faced while testing them. </p>
  
  <p>I generally look for</p>
  
  <ol>
  <li><p>response status (http code is among 200/400/500)</p></li>
  <li><p>response headers (cache control, response type, content length ) </p></li>
  <li><p>if expected  fields / values are present in json response. </p></li>
  </ol>
  
  <p>I want to know what else to look for and issues in general while testing rest based web services</p>
