Vagrant is used to start and provision three nodes using chef-zero. These nodes are given static private IPs from the 172.0.0.0/16 range. If these need to be changed, simply edit the Vagrantfile to update them, and also change the spec/integration/cluster_spec.rb file. Unfortunately Vagrant starts a separate instance of chef-zero for each node, so shared information through Ohai, such as IP address, cannot be searched for.
vagrant up
Open http://localhost:2112 in your browser. NOTE: Strange things are happening with Google Chrome, and the page seems to be cached in the browser. Firefox and Safari do not exhibit this behaviour, and the pages are displayed in the expected round-robin manner.
The Rspec tests cover the two cookbooks for the servers, and an integration test that checks the server response, as well as the round-robin response correctness.
Install the dependencies.
bundle install
Run the unit tests.
rspec
Run the integration tests straight after firing up a new stack.
vagrant up
rspec --tag integration
There is a basic .kitchen.yml file which describes the platform on Ubuntu and defines two suites for the web and app.

The sample application is being served from a Github gist, found here: https://gist.github.com/f67f50ee73bffa14d869.git Changes to this script can be propagated by simply reprovisioning the app servers (or the entire stack).
