Rails - May 2006 - testing named routes

Hello,
I''m trying to test routes named within a map.with_options statement.
I have in routes.rb:

  map.with_options :controller => ''films'' do |f|
    f.overviews   ''films/:index'', :action =>
''index'', :requirements => { :index =>
/index(artist|date|title)\.html/ }, :index => ''new''
    etc...
  end

and my test:
    opts = { :controller => "films", :action =>
"index", :index => "indexdate.html" }
    assert_routing overviews_url(:controller => "films", :index
=> "indexdate.html"), opts

which gives me:
  2) Error:
test_routes(FilmsControllerTest):
NoMethodError: You have a nil object when you didn''t expect it!
The error occured while evaluating nil.rewrite
   
/usr/lib/ruby/gems/1.8/gems/actionpack-1.12.0/lib/action_controller/base.rb:459:in
`url_for''
    generated/routing/named_routes/overviews.rb:2:in `overviews_url''
   
/usr/lib/ruby/gems/1.8/gems/actionpack-1.12.0/lib/action_controller/test_process.rb:431:in

/usr/lib/ruby/gems/1.8/gems/actionpack-1.12.0/lib/action_controller/test_process.rb:431:in
`method_missing''
    functional/films_controller_test.rb:85:in `test_routes''

How can I reference a named route in map.with_options? or is this just plain
wrong :)

thanks
