...и писать дальше тесты, как и раньше.

## Тестирование: расширенный пример { #testing-extended-example }

Теперь давайте расширим наш пример и добавим деталей, чтоб посмотреть, как тестировать различные части приложения.

### Расширенный файл приложения **FastAPI** { #extended-fastapi-app-file }

Мы продолжим работу с той же файловой структурой, что и ранее:

```
.
├── app

... und haben den Code für die Tests wie zuvor.

## Testen: erweitertes Beispiel { #testing-extended-example }

Nun erweitern wir dieses Beispiel und fügen weitere Details hinzu, um zu sehen, wie verschiedene Teile getestet werden.

### Erweiterte **FastAPI**-Anwendungsdatei { #extended-fastapi-app-file }

Fahren wir mit der gleichen Dateistruktur wie zuvor fort:

```
