title: File upload test using Katalon when the 'browse' button isn't an input element
body: <p>I want to test a file upload but as opposed to the <a href="https://www.katalon.com/resources-center/tutorials/handle-file-uploads/#" rel="nofollow noreferrer">How to Handle File Uploads</a> tutorial, the 'Browse' button in my case isn't an Input element.
  I've attached a pic of the HTML script of the 'Browse' button:

  and this is how it looks on the website:

  <p>How can I test a file upload in this case without dealing with the 'Open' explorer window?</p>
  
  <p>Thanks.</p>
