Functional tests fail with acts_as_authenticated installed

Hi, all!
How can I fake authentication within a functional test?
The problem is, after I've installed acts_as_authenticated all requests in my functional test are (correctly) redirected to login screen because test "user" is not logged in.
I need to "log in" in functional test setup method, but have no ideas about that.
Help me please.

Yours sincerely,

Hi, did you add a valid user and it's crenditials to the relevant
model's fixture? In any case, please post your relevant test and
associated fixtures file and we can better assist you.


Thank you.
Got it.
login_as :some_vaild_user
makes the trick.

Yours sincerely,
