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: test_dns.rb
    path of file: ./repos/artichoke/artichoke-backend/vendor/ruby/test/resolv
    
    the code of the file until where you have to start completion: # frozen_string_literal: false
require 'test/unit'
require 'resolv'
require 's
    
  def test_invalid_byte_comment
    bug9273 = '[ruby-core:59239] [Bug #9273]'
    Tempfile.create('resolv_test_dns_') do |tmpfile|
      tmpfile.print("\xff\x00\x40")
      tmpfile.close
      assert_nothing_raised(ArgumentError, bug9273) do
        Resolv::DNS::Config.parse_resolv_conf(tmpfile.path)
      end
    end
  end
