Can't test application controller methods in functional tests?

Rails
1

I have two methods in application controller that I want to test from
ForumController:

class ApplicationController < ActionController::Base
…
def logout
session[:username] = nil
session[:admin] = nil
redirect_to(request.request_uri)
end
…
def home
redirect_to(:controller => ‘forum’, :action => ‘list_forum’)
end

class ForumController < ApplicationController
layout “forum”
…
end

For method home, action list_forum works according to my test, so that
shouldn’t be the problem. The corresponding tests gives errors:

require File.dirname(FILE) + ‘/…/test_helper’
require ‘forum_controller’

Re-raise errors caught by the controller.

class ForumController; def rescue_action(e) raise e end; end

class ForumControllerTest < Test::Unit::TestCase
#add fixtures:
fixtures :messages, :message_threads, :message_boards, :forums

def setup
@controller = ForumController.new
@request = ActionController::TestRequest.new
@response = ActionController::TestResponse.new
end
…

test logout (all cases)

def test_logout
get :logout, nil, nil
assert_response :success
assert_nil session[:username]
assert_nil session[:admin]

get :logout, nil, {:username => 'bogus'}
assert_response :success
assert_nil session[:username]
assert_nil session[:admin]

get :logout, nil, {:username => 'Admin', :admin => 1}
assert_response :success
assert_nil session[:username]
assert_nil session[:admin]

end

test home

def test_home
get :home
assert_response :success
assert_redirected_to ‘list_forum’
assert_not_nil assigns[“forums”]
end
end

    forum_controller_test.rb:446:in `test_logout’

What’s up with that? Can I not test ApplicationController methods in
ForumController?

Also, how can I set requested uri?
