.facts_to_platform(facts) ⇒ Object

This will take a fact set and return the beaker platform of that machine This is necissary as beaker needs the platform set up correctly to know which commands to run when we do stuff. Personally I would prefer beaker to detect the platform as it would not be that hard, especially once puppet is installed, oh well.

.provision_and_test(host, puppet_class, opts = {}, repo = Onceover::Controlrepo.new) ⇒ Object

This actually provisions a node and checks that puppet will be able to run and be idempotent. It hacks the beaker NetworkManager object to do this. The reason is that beaker is designed to run in the following order:

1. Spin up nodes
2. Run all tests
3. Kill all nodes

This is not helpful for us. We want to be able to test all of our classes on all of our nodes, this could be a lot of vms and having them all running at once would be a real kick in the dick for whatever system was running it.
