Recommendation for testing in readme?

[scottmessinger]

Hi! I'm starting to integrate one of the Google APIs into our app using this library. However, I'm a bit stumped on how to test. How do you all recommend writing tests when using this library? Specifically, should we mock using something like Mox or Rewire or just let our tests hit the Google APIs?

Also, in the oauth section, I noticed the instructions to get a token for testing, but I'm a bit unclear the advantages/disadvantages of that token. What is the token allowing/disallowing?

Thanks in advance!
