Functional testing Authlogic? - ruby-on-rails

Question

In a few of my controllers I have a before_filter that checks if a user is logged in? for CRUD actions.
application.rb
def logged_in?
unless current_user
redirect_to root_path
end
end
private
def current_user_session
return #current_user_session if defined?(#current_user_session)
#current_user_session = UserSession.find
end
def current_user
return #current_user if defined?(#current_user)
#current_user = current_user_session && current_user_session.record
end
But now my functional tests fail because its redirecting to root. So I need a way to simulate that a session has been created but nothing I've tried has worked. Heres what I have right now and the tests pretty much ignore it:
test_helper.rb
class ActionController::TestCase
setup :activate_authlogic
end
posts_controller_test.rb
class PostsControllerTest < ActionController::TestCase
setup do
UserSession.create(:username => "dmix", :password => "12345")
end
test "should get new" do
get :new
assert_response :success
end
Am I missing something?

Answer 1

You should pass ActiveRecord object in UserSession.create
Something like:
u = users(:dmix)
UserSession.create(u)

First you need to activate AuthLogic so that you can use it in your tests.
setup :activate_authlogic
Then you need a valid user record as Anton Mironov pointed out.

Answer 3

All I do in my rspec tests for my controller is create a User with Machinist and then assign that user to be the current_user.
def login_user(options = {})
user = User.make(options)
#controller.stub!(:current_user).and_return(user)
end
and this attaches the current_user to the controller, which would mean that your logged_in? method would work in your tests.
You obviously would probably need to adapt this to work in Test::Unit, and without Machinist if you don't use it, as I use rspec, but I'm sure the principle is the same.

Answer 4

Put this in test_helper.rb if you want all your tests to setup Authlogic:
class ActionController::TestCase
def self.inherited(subclass)
subclass.instance_eval do
setup :activate_authlogic
end
end
end

Here is a link to the AuthLogic test documentation. It's an important one but is a bit buried (the same link Simone posted, however his didn't work anymore).
That page has all the information you need to get going testing you application using AuthLogic for authentication.
Additionally, as railsninja suggested, use factories not fixtures. Take a look at factory_girl and machinist; pick your poison, they are both good.
