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

require "helper"

module Nokogiri
  module XML
    class Node
      class TestSubclass < Nokogiri::TestCase
        {
          Nokogiri::XML::CDATA => 'doc, "foo"',
          Nokogiri::XML::Attr => 'doc, "foo"',
          Nokogiri::XML::Comment => 'doc, "foo"',
    
    
            def test_subclass_initialize_#{klass.name.gsub("::", "_")}
              doc = Nokogiri::XML::Document.new
              klass = Class.new(#{klass.name}) do
                attr_accessor :initialized_with

                def initialize *args
                  @initialized_with = args
                end
              end
              node = klass.new(#{constructor}, 1)
              assert_equal [#{constructor}, 1], node.initialized_with
            end
