title: How to run test case on 2 devices with sequence in appium testing
body: <p>Any one has experience in testing app chat. like : accountA send a message to accountB.
  So iam automating this flow by below steps :
  <p>1. open app in device 1 and send message to other account.
  <p>2. open app in device 2 and verify receiving message successfully. 
  <p>I try to run in appium but the test case is only run in only 1 device. while we expect the 1st above step running on device 1. and the second step  is running on device 2.</p>
