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_rdoc_rdoc.rb
    path of file: ./repos/rdoc/test/rdoc
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
require_relative 'helper'

class TestRDocRDoc < RDoc::TestCase

  def setup
    super

    @rdoc = RDoc::RDoc.new
    @rdoc.options = 
    
  def test_remove_unparseable_CVE_2021_31799
    omit 'for Un*x platforms' if Gem.win_platform?
    temp_dir do
      file_list = ['| touch evil.txt && echo tags']
      file_list.each do |f|
        FileUtils.touch f rescue omit
      end

      assert_equal file_list, @rdoc.remove_unparseable(file_list)
      assert_equal file_list, Dir.children('.')
    end
  end
