def instance
  __memoized.fetch_or_store(:instance) do
    metadata = self.class.metadata
    described = described_class || metadata.fetch(:description_args).first

    if described.is_a?(Class)
      if metadata[:rspec_arguments] || metadata[:method] || metadata[:class_method]
        raise 'Instance is only available when testing class instances or instance methods' if metadata[:class_method]

        process_instance(described)
      else
        described.new
      end
    end
  end
end

#subject ⇒ Object

The only monkey-patching in this gem.

Mostly untouched, except we call ‘process_subject`, instead of simply instantiating the described_class.
