How to automatically test Unity3D games on devices?

Question

Automation

Hey!
I'm looking for a way to automatically test Unity3D games on devices (iOS, Android).
Any game has functionality that
a) needs to be tested on "live" hardware
b) writing a unit test for this is extremely difficult or impossible
Examples: is the game progress saved correctly between application restarts, is the file cached after downloading from the server, etc. .
I really want to check all this not by hand, but automatically, run the tests after each commit.
Please tell me if you have experienced something similar?
