I see http://betterspecs.org/#describe asking to use the Ruby documentation convention of . (or ::) when referring to a class method's name and # when referring to an instance method's name. 

In this case get_module_uri isn't a class method, but since is included in a mixin, not sure if it's better to use . than # to describe it. 

Also, not sure if we're not using the # convention because of anything. Really this comment jus tries to ask since obviously I don't rock at reviewing specs, trying to fix myself.
