In config/environments/test.rb

config.google_adapter = Google::Fake.new

In config/environments/production.rb

config.google_adapter = Google::Api.new(ENV.fetch('GOOGLE_CLIENT_ID'), ENV.fetch('GOOGLE_CLIENT_SECRET'))

Usage

documents = Adapter.google.get_documents('_USER TOKEN_')

if documents.success == true
  puts 'Here are your documents'
  puts documents.data.inspect
else
  puts 'Error!'
  puts documents.errors.inspect
end

Benefits

1. Possible to use across app test environment just fake adapter and avoid HTTP connection, however need to make sure, that Api and Fake adapters are in sync with their interface.
2. Isolated testing of the real adapter Api
3. Avoid mocking in the tests easier
