When I run my functional tests one by one they pass with no problems. However when I run them via rake test:functionals several individual tests fail with the same error.
The error is as follows
NoMethodError: You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]

and this line of code seems to be a common cause
@current_user_session.destroy
It seems its something to do with authlogic and cookies. but I dont understand why these same tests when when ran individually pass.
Can anyone give me some pointers where to look?
