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_getoptlong.rb
    path of file: ./repos/artichoke/artichoke-backend/vendor/ruby/test
    
    the code of the file until where you have to start completion: require 'test/unit'
require 'getoptlong'

class TestGetoptLong < Test::Unit::TestCase

  def verify(test_argv, expected_remaining_argv, expected_options)
    # Save ARGV and replace it with a test A
    
  def test_optional_argument_missing
    expected_options = [
      '--yyy: '
    ]
    expected_argv = %w[foo bar]
    options = %w[--yyy --y --y -y --bbb --bb --b -b]
    options.each do |option|
      argv = ['foo', 'bar', option]
      verify(argv, expected_argv, expected_options)
    end
  end
