functional vs integration tests with restful_auth

Hi,

# in functional/projects_controller_test.rb

   def test_should_show_project_home_page_as_public_exists
     get :show, :id => 2
     assert_redirected_to :controller => 'pages', :action => 'show', 'id' => 'home', :project_id => 2
   end

SUCCEEDS

   def test_should_show_project_as_submitter_no_submission
     login_as('imasubmitter')
     get :show, :id => 2
     default_text = "No submissions present for this project."
     assert_select "p#test-for", default_text
   end

SUCCEEDS

hi, i did get the login working but i still wonder what it would take
to be able to use, in an integration test, the methods .logged_in?
and .is_member_of methods from the authentication and authorization
plug ins
