ideas for cucumber-defining and -testing vagrant vms and docker containers

testing docker setup with cucumber

Scenario: Vagrant/Docker Setup
  Given a host with 'vagrant' installed
  When i run vagrant
  Then it should have a vm named 'default'
  And it should have a vm named 'web' 
  And it should have a vm named 'app'

Scenario: Docker Images in web server
  Given a vm named 'web'
  Then it should have docker installed
  And it should have an image 'busybox'

Scenario: Docker Images running on web server
  Given a enabled vm named 'web'
  Then it should have at least 3 containers with image 'busybox' running
  And it should have at least 3 ports mapped to '80'
