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: todo_xml_api_test.rb
    path of file: ./repos/tracks/test/integration
    
    the code of the file until where you have to start completion: require 'test_helper'

class TodoXmlApiTest < ActionDisp
    
 def test_post_create_todo_with_multiple_tags_and_space
    # testing fix for #1229
    authenticated_post_xml_to_todo_create "

    <tag><name>foo </name></tag>
    <tag><name> bar</name></tag>
    <tag><name>  bingo  </name></tag>
  </tags>
</todo>"

    assert_response :success
    todo = @user.todos.where(:description => "this will succeed 3").first
    assert_not_nil todo
    assert_equal "bar, bingo, foo", todo.tag_list
