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_lexer.rb
    path of file: ./repos/ruby/test/ripper
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
begin
  require 'ripper'
  req
    
  def test_raise_errors_keyword
    all_assertions do |all|
      BAD_CODE.each do |(err, code, message)|
        all.for([err, code]) do
          assert_raise_with_message(SyntaxError, message) { Ripper.tokenize(code, raise_errors: true) }
        end
      end
    end
  end
