Testing for this cookbook includes rspec (chefspec) as well as test-kitchen. The following environment variables must be set in order to test this cookbook using a real connection to Rackspace:
RACKSPACE_USERNAME

Additionally, you should configure test-kitchen to build a Rackspace cloud server in the region you'd like test. You may also set the environment variable RACKSPACE_AGENT_CHANNEL to whichever monitoring agent release channel you'd like to use (defaults to stable).
