Testing routes / index.html

I have a plain HTML "landing page" for my app. Maybe it's silly, but I'd like to have an integration test that confirms this is functioning as intended. I would have thought this doable, but ...

def test_basic     get 'index'     assert_response :success     assert_template 'index.html' end

... doesn't actually work. The response is <404> and the template handler is routing_error.html.

Can someone enlighten me here?

(This is Rails 1.1.6, not edge, if that makes a difference...)
