Subject: [PATCH] tests/config: added basic assert support (compatible with
 busted)

There is no dependency on a testing library yet, so I added a
basic interface for mocking and asserting test values to get
something to start with. I'll probably replace it with busted
or telescope later on to get nicer testing output.
