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_invalid.rb
    path of file: ./repos/ruby-packer/ruby/test/csv/parse
    
    the code of the file until where you have to start completion: # -*- coding: utf-8 -*-
# frozen_string_literal: false

require_relative "../helper"

class TestCSVParseInvalid 
    
  def test_no_column_mixed_new_lines
    error = assert_raise(CSV::MalformedCSVError) do
      CSV.parse("\n" +
                "\r")
    end
    assert_equal("New line must be <\"\\n\"> not <\"\\r\"> in line 2.",
                 error.message)
  end
