When creating rspec test for a method like this, should I basically be verifying correctness of arguments and whether or not it returns a usable value? In the case of this particular method, it leads to a side effect in `load ezbake.rb` which is a file populated by the `lein run -- stage ...` command in ezbake context, which makes available EZBake::Config, the value of which is then assigned to a module variable, `@config`

The details of this behavior are a little difficult to validate but I think I could stub `load`, maybe, to assign some hash from the rspec namespace to Beaker::DSL::EZBake. Working on that now...and stubbing Dir.chdir
