Cookies testing

I’m trying to read the expiration time of a cookie for testing, and
I’m puzzled because in this functional test both assertion pass …

def test_authentication_with_cookie
post :login, :username => ‘foo’, :password =>
‘passwd’, :remember_me => ‘1’
assert_not_nil user = User.find(:first, session[:user_id])
assert_equal cookies[:auth_token], user.remember_token
assert_equal cookies[:auth_token], user.remember_token_expiration
end

Someone has a clue of what’s happening here ? …
