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_constant.rb
    path of file: ./repos/ruby-packer/ruby/test/mkmf
    
    the code of the file until where you have to start completion: # frozen_string_literal: false
require_relative 'base'

class TestMkmf
  class TestTryConstant < TestMkmf
    def test_simple
      assert_equal( 0, mkmf {t
    
    def test_long
      sizeof_int = config_value("SIZEOF_INT").to_i
      sizeof_long = config_value("SIZEOF_LONG").to_i
      if sizeof_long > sizeof_int
        type = 'long'
      else
        sizeof_long_long = config_value("SIZEOF_LONG_LONG").to_i
        return if !sizeof_long_long or sizeof_long_long <= sizeof_int
        type = 'LONG_LONG'
      end
