Using omniauth-oauth2 alongside omniauth-facebook and omniauth-google-oauth2 for social authentication with Devise, we saw this obscure error cropping up in our Cucumber suite. We couldn't figure out what was going wrong. Google led us on some goose hunts. Any ideas?

Given I am a visitor # features/step_definitions/authentication_steps.rb:6
When I visit the login or register page # features/step_definitions/authentication_steps.rb:52
And I login with Google+ # features/step_definitions/authentication_steps.rb:29
Then I see the text "Signed in successfully." # features/step_definitions/web_steps.rb:159
We discovered that the error only occurred when a previous test ran that used Timecop to travel forward in time by 1 day. As it turns out, Google tokens only last for 3600 seconds, so travelling an hour ahead invalidated the original token. Refreshing was then made impossible.
Moral of the story: don't forget to Timecop.return after travelling in time.
