... 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.

# Классы как зависимости { #classes-as-dependencies }

Прежде чем углубиться в систему **Внедрения Зависимостей**, давайте обновим предыдущий пример.

## `dict` из предыдущего примера { #a-dict-from-the-previous-example }

В предыдущем примере мы возвращали `dict` из нашей зависимости («dependable»):
