It looks like it's trying to look up a class to check if a variable is in
there, so it needs a TypeCollection (known_resource_types) which comes from an
environment. It should work to just create an environment and stub it on the
scope (unfortunately, it normally comes from compiler, so you can't just set
it, but there's no reason to actually make a compiler).
env = Puppet::Node::Environment.new('nodename')
s = Puppet::Parser::Scope.new
s.stubs(:e).returns env
