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_file_exhaustive.rb
    path of file: ./repos/ruby-packer/ruby/test/ruby
    
    the code of the file until where you have to start completion: # frozen_string_literal: false
require "test/unit"
require "fileutils"
require "tmpdir"
require "socket"
require '-test-/file'

class TestFileExhaustive < Test::Unit::TestCase
  DRIVE = Dir.pwd[%r'\A(?:[a-z]:|//[^/]+/[^/]
    
  def test_path
    [regular_file, utf8_file].each do |file|
      assert_equal(file, File.open(file) {|f| f.path})
      assert_equal(file, File.path(file))
      o = Object.new
      class << o; self; end.class_eval do
        define_method(:to_path) { file }
      end
      assert_equal(file, File.path(o))
    end
  end
