title: Jmeter assert json response element to be NOT NULL
body: <p>I am getting Json response, I have parsed it using <em>jp@gc - JSON Path Extractor</em> and got an element say 'Access_Token'. This Access_Token is dynamic. So I just want to make sure that this element is <strong><em>not null</em>.</strong></p>
  
  <p>Any leads would be much appreciated.</p>
