    Metadata details:

    the code of the file until where you have to start completion: require 'spec_helper'
require 'puppet/agent'
require 'puppe
    
          def processing; end
          def handling; end

          def run(client_options = {})
            # Simulate a hanging agent operation that also traps errors.
            begin
              ::Kernel.sleep(5)
              processing()
            rescue
              handling()
            end
