  new_logger_class = Class.new(self::Base)
  new_logger_class.instance_variable_set(:@service_name, service_name)
  new_logger_class.instance_variable_set(:@repo, repo)

end

.stub_method(message, value) ⇒ Object

An isolated lambda to serve as the method body for stubs, both in the ::new method and in the Base#initialize method. Avoids repeating already clunky-looking logic.
