Granted, this is a really simple combination, but I ran into a few hurdles on my first attempt, and thought someone might benefit from my feeding github this working, minimal example of using Cucumber, Capybara, Poltergeist and PhantomJS to execute web tests against a remote application.
Make sure you install PhantomJS first on your machine.
For mac osx, you can just do a brew install phantomjs. If you have rvm installed on your
machine (recommended), then I have already checked in .ruby-version and .ruby-gemset to ensure
your gem installation doesn't clash with existing ruby environment setups.
Steps to run the tests
bundle install
bundle exec cucumber
