functional tests with machinist and authlogic

Authlogic and Machinist are two libraries that are a great help in getting a Rails app up and running quickly. But once we had a prototype running and some solid unit tests going, I ran into a snag. How do I create Users and UserSessions in a way that agrees with AuthLogic so that my requires_user before filter is working properly within a functional test?

The Machinist test_case.rb has some good explanation, but they focus on fixtures and leave out some easy steps.

Here's how I setup my functional tests: In test_helper.rb I added a login() method : 
  def login(u = nil) 
    user = User.make(u)
    assert UserSession.create(user)
    user
  end
In blueprints.rb, i added the fields that AuthLogic needs to authenticate a user: 
User.blueprint do
  email   { "testuser@company.biz" }
  password    { "test" }
  password_confirmation    { password }
  
  #this is all needed so we can log in for functional tests
  password_salt {Authlogic::Random.hex_token }
  crypted_password { Authlogic::CryptoProviders::Sha512.encrypt(password + password_salt) }
  persistence_token { Authlogic::Random.hex_token }
  single_access_token { Authlogic::Random.friendly_token }
  perishable_token { Authlogic::Random.friendly_token }
  active { true }
end
Finally, in the functional tests, you can simply use login() to simulate a session within the functional test: 
  test "should force login" do
    get :index
    assert_redirects_to login_path
  end
  
  test "should get index" do
    login
    get :index
    assert_response :success
    assert_not_nil assigns(:items)
  end
I hope this helps. If you have any suggestions or improvements, please leave a comment.
