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: demo_exception.rb
    path of file: ./repos/raygun4ruby/lib/raygun
    
    the code of the file until where you have to start completion: module Raygun

  class ItWorksException < StandardError; end

  module DemoExcepti
    
    def track_test_exception
      Raygun.configuration.silence_reporting = false
      raise ItWorksException.new("Woohoo! Your Raygun<->Ruby connection is set up correctly")
    rescue ItWorksException => e
      response = Raygun.track_exception(e)

      if response.success?
        puts "Success! Now go check your Raygun Dashboard"
      else
        puts "Oh-oh, something went wrong - double check your API key"
        puts "API Key - " << Raygun.configuration.api_key << ")"
        puts "API Response - " << response
      end
    end
