title: Test automation Google Apps Script Gmail Add-ons
body: <p>I am working on Gmail Add-on using Google Apps Script. I am using <a href="https://script.google.com" rel="nofollow noreferrer">Clasp</a> to develop it on locally then using this I am pushing it to <a href="https://codelabs.developers.google.com/codelabs/clasp" rel="nofollow noreferrer">script.google.com</a>. </p>
  
  <p>In local, I can do <strong>Unit testing</strong> using any JavaScript testing framework. </p>
  
  <p>But is there any way to do <strong>Integration testing</strong> and automate it?</p>
