Test için bir dependency'yi override etmek istediğinizde, key olarak orijinal dependency'yi (bir function), value olarak da override edecek dependency'nizi (başka bir function) verirsiniz.

Böylece **FastAPI**, orijinal dependency yerine bu override'ı çağırır.

`Depends()` приймає параметр `scope`, який може бути:

{* ../../docs_src/dependencies/tutorial008e_an_py310.py hl[12,16] *}

`Depends()` принимает параметр `scope`, который может быть:

* « function » : démarrer la dépendance avant la *fonction de chemin d'accès* qui gère la requête, terminer la dépendance après la fin de la *fonction de chemin d'accès*, mais **avant** que la réponse ne soit renvoyée au client. Ainsi, la fonction de dépendance sera exécutée **autour** de la *fonction de chemin d'accès*.

Bu şekilde **video** veya **ses** de akıtabilirsiniz; hatta işledikçe üretilip gönderilebilir.

## `yield` ile bir `StreamingResponse` { #a-streamingresponse-with-yield }

*Path operation function* içinde `response_class=StreamingResponse` belirtirseniz, her veri parçasını sırayla göndermek için `yield` kullanabilirsiniz.

### Dependencias con `yield` y `scope` { #dependencies-with-yield-and-scope }

En la versión 0.121.0, FastAPI agregó soporte para `Depends(scope="function")` para dependencias con `yield`.

Usando `Depends(scope="function")`, el código de salida después de `yield` se ejecuta justo después de que la *path operation function* termina, antes de que la response se envíe de vuelta al cliente.
