ruby on rails - Is it possible to set when a cookie expires inside an integration test? -

is there way in integration tests manipulate cookie's expiration date (as test if taken account properly). example, if cookies['user_id'] exists in test, manipulate this:

cookies['user_id'].expires = time.zone.now - 1.day 

(this returns undefined method 'expires=')
i'm using minitest in rails.

you can use timecop time travel in test:

def setup   do_something_which_sets_cookie   timecop.freeze(1.month.from_now)    # or how ever long takes cookie expire end  def teardown    timecop.return end 

this can nice approach if want test how application behaves after period of time without tying test implementation details.

otherwise need ensure cookie exists before setting expiry:

cookies['user_id'].expires = time.zone.now - 1.day if cookies['user_id']
