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

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

Also, how can I set requested uri?
