How to set locale default_url_options for functional tests (Rails)

Question

In my application_controller, I have the following set to include the locale with all paths generated by url_for:

  def default_url_options(options={})
    {

Looking through how the controller test case generates the url there doesn't seem to be a direct way to have it use the defualt_url_options. The main block that actually does the url creationg (in the tests) looks like this (http://github.com/rails/rails/blob/master/actionpack/lib/action_controller/test_case.rb):

private
  def build_request_uri(action, parameters)
    unless @request.env['REQUEST_URI']
      options = @controller.__send__(:rewrite_options, parameters)
      options.update(:only_path => true, :action => action)

      url = ActionController::UrlRewriter.new(@request, parameters)
      @request.request_uri = url.rewrite(options)
    end
  end

This gets called by the process method which is in turn called by the get, post, head, or put methods. One way to maybe get what you are looking for might be to alias_chain the process method.

class ActionController::TestCase
  def process_with_default_locale(action, parameters = nil, session = nil, flash = nil, http_method = 'GET')
    parameters = {:locale=>'en'}.merge(parameters||{})
    process_without_default_locale(action, parameters, session, flash, http_method)
  end
  alias_method_chain :process, :default_locale
end

You'll want to put that into your test helper, outside of the TestCase class I think. Let me know how it works for you, I haven't really tested it out so we'll see.
