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: simple_abstract_check.rb
    path of file: ./repos/gitlabhq/lib/gitlab/health_checks
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Gitlab
  module HealthChecks
    module SimpleA
    
      def readiness
        check_result = check
        return if check_result.nil?

        if successful?(check_result)
          HealthChecks::Result.new(name, true)
        elsif check_result.is_a?(Timeout::Error)
          HealthChecks::Result.new(name, false, "#{human_name} check timed out")
        else
          HealthChecks::Result.new(name, false, "unexpected #{human_name} check result: #{check_result}")
        end
