You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: instrumentation_spec.rb
    path of file: ./repos/flexirest/spec/lib
    
    the code of the file until where you have to start completion: require 'spec_helper'

class InstrumentationExampleClient < Flexirest::Base
  base_url "http://www.example.
    
      def append_info_to_payload(payload) ; {} ; end
      def self.log_process_action(payload) ; [] ; end
    end

    class InstrumentationTimeSpentExampleClient < InstrumentationTimeSpentExampleClientParent
      include Flexirest::ControllerInstrumentation

      def test
        payload = {}
        append_info_to_payload(payload)
        self.class.log_process_action(payload)
      end
    end
