Routes in Functional Tests?

I have the following:

:: generic_controller.rb ::

class GenericController < ApplicationController   def activate   end

  def index   end end

:: routes.rb ::

ActionController::Routing::Routes.draw do |map|   map.activate '/activate/:activation_code', :controller => 'generic', :action => 'activate' end

:: generic_controller_test.rb ::

require File.dirname(__FILE__) + '/../test_helper'

class GenericControllerTest < ActionController::TestCase   def test_activate_path     get :index     assert_not_nil activate_path("something")   end end

0 remus test/functional % ruby generic_controller_test.rb Loaded suite generic_controller_test Started . Finished in 0.280308 seconds. 1 tests, 1 assertions, 0 failures, 0 errors

If I comment out the get :index call in my test file, I get this:

0 remus test/functional % ruby generic_controller_test.rb Loaded suite generic_controller_test Started E Finished in 0.282201 seconds.   1) Error: test_activate_path(GenericControllerTest): NoMethodError: You have a nil object when you didn't expect it! The error occurred while evaluating nil.rewrite     /usr/lib64/ruby/gems/1.8/gems/actionpack-2.0.2/lib/ action_controller/base.rb:616:in `url_for'     (eval):17:in `activate_path' /usr/lib64/ruby/gems/1.8/gems/actionpack-2.0.2/lib/action_controller/ test_process.rb:463:in `send!' /usr/lib64/ruby/gems/1.8/gems/actionpack-2.0.2/lib/action_controller/ test_process.rb:463:in `method_missing'     generic_controller_test.rb:7:in `test_activate_path' /usr/lib64/ruby/gems/1.8/gems/activesupport-2.0.2-/lib/active_support/ testing/default.rb:7:in `run'

What is it about the get call that "turns on" the named route?
