• What you need to start:

• Install ruby >= 1.9.3
• Install bundle: sudo gem install bundler --no-rdoc --no-ri
• Install openssl for ruby: sudo apt-get install libopenssl-ruby
• Install mysql client: sudo apt-get install libmysqlclient-dev
• Install xvfb for headless tests: sudo apt-get install xvfb
• run: bundle install

...you should be ready to go, bundle will take care or installing all you need.

Now you can run the tests just typing in:

1. 'cucumber' if you want to run you tests locally
2. 'cucumber --profile=sauce' if you want to run your test on SauceLabs
