I want to do some functional testing. I stumbled over the method
follow_redirect!() somewhere, but evidently this doesn't seem to exist
in my Rails version (1.2.5 or so)?! Then I tried follow_redirect()
(without the exclamation mark), and I get the following error:
Are you doing a functional test or an integration test. IIRC
follow_redirect is only for the latter (since functional tests revolve
around a single request).
