### Use the `app.dependency_overrides` attribute

For these cases, your **FastAPI** application has an attribute `app.dependency_overrides`, it is a simple `dict`.

To override a dependency for testing, you put as a key the original dependency (a function), and as the value, your dependency override (another function).

/// note | "Technische Details"

Ein `Request` hat ein `request.scope`-Attribut, welches einfach ein Python-`dict` ist, welches die mit dem Request verbundenen Metadaten enthält.

Ein `Request` hat auch ein `request.receive`, welches eine Funktion ist, die den Hauptteil des Requests empfängt.

Das `scope`-`dict` und die `receive`-Funktion sind beide Teil der ASGI-Spezifikation.
