Test weirdness

Hi gurus,

I have this in routes.rb:

map.root :controller => 'items'

This in my method controller

redirect_to_root( msg = 'Oops!' )

And this in my application controller

  def redirect_to_root( msg = nil )
    flash[ :notice ] = msg if msg
    redirect_to root_path
  end

With this in my functionals test for the method,

assert_redirected_to root_path

I get the following error on rake test:functionals

1) Failure:
test_should_create_donor(DonorsControllerTest) [/test/functional/
donors_controller_test.rb:29]:
Expected response to be a redirect to <http://test.host/> but was a
redirect to <http://test.host/items>.

Any idea how to fix this? I've spent hours trying to eliminate this
error...

Many TIA,
Craig
