Using RSPEC with AUTHLOGIC

So, this helps a lot when testing applications using RSPEC that use the authlogic gem for authentication. 
Just require and include the following module in your rspec file. Then you can simply write things like:

  before(:each) do
    login_as_user
  end

at the top of your specs, and you should be good to go...

module ControllerHelpers
  
  def login_as_user
    # define user and session
    @current_user = mock_model(User, :login => "test_user")
    @current_session = mock_model(UserSession)

    controller.stub!(:current_user).and_return @current_user
    controller.stub!(:current_session).and_return @current_session
  end
  
  def not_logged_in
    controller.stub!(:current_user).and_return nil
  end
  
  def current_user(stubs = {})
    @current_user ||= mock_model(User, stubs)
  end

  def user_session(stubs = {}, user_stubs = {})
    @current_user ||= mock_model(UserSession, {:user => current_user(user_stubs)}.merge(stubs))
  end

  def login(session_stubs = {}, user_stubs = {})
    UserSession.stub!(:find).and_return(user_session(session_stubs, user_stubs))
  end

  def logout
    @user_session = nil
  end
  
end
