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_cparser.rb
    path of file: ./repos/ruby-packer/ruby/test/fiddle
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
begin
  require_relative 'helper'
  require 'fiddle/cparser'
rescue LoadError
end

module Fiddle
  class TestCParser < TestCase
    include CParser

    def t
    
    def test_long_ctype
      assert_equal(TYPE_LONG, parse_ctype('long'))
      assert_equal(TYPE_LONG, parse_ctype('long int'))
      assert_equal(TYPE_LONG, parse_ctype('signed long'))
      assert_equal(TYPE_LONG, parse_ctype('signed long int'))
      assert_equal(-TYPE_LONG, parse_ctype('unsigned long'))
      assert_equal(-TYPE_LONG, parse_ctype('unsigned long int'))
    end
