Testing Facebook in-app browser

I’m a new in Appium and I have to create tests that open web page inside Facebook in-app browser (the WebView that opens when you click link in the Facebook native application).
I have some questions about this issue:

  1. How can I run such tests on Android emulators and iOS simulators?
  2. How I can create Facebook Test User (I’m writing my tests in .net)?


I am also interested in this topic. I see that the topic is older. Did you found any solution so far?

Anyone has resolve the Facebook in-app browser testing ? I’m interested on how to do it, please help! thanks in advance
