I've noticed that when testing cookies, the test can only see the values of cookies that have been changed in actions and doesn't take into account what the cookie was set to originally.
For example, this test passes (given do_something doesn't nothing to the cookie) when you'd expect cookie['foo'] to equal 'bar'.
def test_should_delete_the_cookie @request.cookies['foo'] = 'bar' get :do_something assert_nil cookies['foo'] end
I've created a ticket: https://rails.lighthouseapp.com/projects/8994/tickets/2768-tests-should-see-all-cookies-not-just-those-that-are-created-or-changed-in-the-controller#ticket-2768-1
which includes a patch.
