I'm not opposed to the hardcoding as long as there's a way we can make the build/test fail in the event we change the path. OTOH, `chef verify` has some code to find the omnibus directory, which might come in handy when we do windows. Also, it would be cool to put this in a class or module (maybe just define it on the ChefDK module for now?) so we can reuse it elsewhere. And finally, You'll want to add the user bin path from rubygems, since we're installing `chef gem` gems to the home dir now.
