This feels like work.
I've put together some very simple BDD test based on the example given.
To run:
Install rvm
\curl -sSL https://get.rvm.io | bash
Install the ruby version 2.1.2, becuase thats the one I am using
rvm install 2.1.2
Install bundler gem
gem install bundler
Navigate to this code and bundle install
bundle install
Finally run the tests
cucumber -p test
This will produce a nice html report called test.html to view the results
