In the Cucumber tests, we do not access the Internet to install test
dependencies -- we assume that you've already run `bundle install` or
`appraisal install` to install those dependencies. Change the RSpec
tests so that the same thing happens.
The code that sets up the blank Rails application we use for testing is
a little messy. Let's use an object to encapsulate this and then refer
to this object every time we access Rails.application.
