Таким же образом вы можете поднять исключение `HTTPException` или что-то подобное в завершающем коде, после `yield`.

Код выхода в зависимостях с `yield` выполняется *после* отправки ответа, поэтому [Обработчик исключений](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank} уже будет запущен. В коде выхода (после `yield`) нет ничего, перехватывающего исключения, брошенные вашими зависимостями.

            assertTrue(ALWAYSACTIVE.accept(mockFile));
