Pytest на Django Каналы не должны проходить, но это делает

Question

Я застрял, работая с TDD мои тесты проходят, когда они не должны, не знаю почему. Должен произойти сбой, модель заказа не обновляется, поэтому я думаю, что она должна выдать ошибку. Другое дело, я не мог записывать данные, когда тест пройден.
