title: How to set current tab in viewpager with tablayout
body: <p>I have a custom viewpager (with swiping disabled for reasons) working with a tablayout. The content changes based on which tab is selected. I want to test this using espresso:
  1) Click on a particular tab
  2) Check some data in a particular page of the tab
  How can I do that. I am a novice to espresso</p>
