title: Automated testing of multi-client workflows with Selenium
body: <p>I'm trying to automate some test cases with Selenium WebDriver.
  My problem is that most test cases need interactions from different devices.
  An example:</p>
  
  <ul>
  <li>Mobile App (Android or iOS) initiates a new workflow</li>
  <li>Desktop user has to approve it</li>
  <li>Mobile user can now continue with the workflow</li>
  <li>Desktop user can continuously see at which step the mobile user currently is</li>
  </ul>
  
  <p>Is is possible to create Selenium Tests that can test these interactions?
  If yes, how?</p>
