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_tempfile.rb
    path of file: ./repos/artichoke/artichoke-backend/vendor/ruby/test
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
re
    
  def test_create_traversal_dir
    assert_mktmpdir_traversal do |traversal_path|
      t = Tempfile.create(traversal_path + 'foo')
      t.path
    ensure
      if t
        t.close
        File.unlink(t.path)
      end
    end
