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_named_characters.rb
    path of file: ./repos/nokogiri/test/html4
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require "helper"

module Nokogiri
  module HTML
    class TestNamedCharacters < Nokogiri::TestCase
      def test_named_character
        copy = NamedCharacters.get("copy")
   
    
      def test_named_character2
        # this test, identical to the previous one, is only here to trigger failure during
        # NOKOGIRI_TEST_GC_LEVEL=verify if we regress on registering the address of
        # cNokogiriHtmlEntityDescription in html_entity_lookup.c.
        #
        # if we ever write a second meaningful test for anything that calls EntityLookup#get then we
        # can remove this test.
        copy = NamedCharacters.get("copy")
        assert_equal(169, NamedCharacters["copy"])
        assert_equal(copy.value, NamedCharacters["copy"])
        assert(copy.description)
      end
