I'm trying to do something like the following:

@special_attributes = Model.new.methods.select # a special subset
@special_attributes.each do |attribute|
  context "A model with #{attribute}"
    setup do
      @model = Model.new
    end
    should "have some special characteristic"
      assert @model.method(attribute).call
    end
  end
end

However, @special_attributes is out of scope when running the unit tests, leaving me with a nil object on line 2. I can't figure out where to define it to bring it in scope. Any thoughts?
