Полученное значение и есть то, что будет внедрено в функцию операции пути и другие зависимости:

```Python hl_lines="4"
{!../../docs_src/dependencies/tutorial007.py!}
```

Код, следующий за оператором `yield`, выполняется после доставки ответа:

# Testing Dependencies with Overrides

## Overriding dependencies during testing

There are some scenarios where you might want to override a dependency during testing.

You don't want the original dependency to run (nor any of the sub-dependencies it might have).

レスポンスを送信する前に`yield`文を含む前のコードのみが実行されます。

```Python hl_lines="2 3 4"
{!../../docs_src/dependencies/tutorial007.py!}
```

生成された値は、*path operations*や他の依存関係に注入されるものです:

```Python hl_lines="4"
{!../../docs_src/dependencies/tutorial007.py!}
```

`yield`文に続くコードは、レスポンスが送信された後に実行されます:

```Python hl_lines="5 6"
{!../../docs_src/dependencies/tutorial007.py!}
```

/// tip | "豆知識"

`async`や通常の関数を使用することができます。

```Python hl_lines="11-15"
{!> ../../docs_src/dependencies/tutorial002.py!}
```

## Adicionando `dependencies` ao decorador da operação de rota

O *decorador da operação de rota* recebe um argumento opcional `dependencies`.

Ele deve ser uma lista de `Depends()`:

//// tab | Python 3.9+

```Python hl_lines="19"
{!> ../../docs_src/dependencies/tutorial006_an_py39.py!}
```

////

///

```Python hl_lines="17"
{!> ../../docs_src/dependencies/tutorial006.py!}
```

////

These dependencies will be executed/solved the same way as normal dependencies. But their value (if they return any) won't be passed to your *path operation function*.

/// tip

Some editors check for unused function parameters, and show them as errors.

## Добавление `dependencies` в *декоратор операции пути*

*Декоратор операции пути* получает необязательный аргумент `dependencies`.

Это должен быть `list` состоящий из `Depends()`:

//// tab | Python 3.9+

```Python hl_lines="19"
{!> ../../docs_src/dependencies/tutorial006_an_py39.py!}
```

////

그러나 여전히 실행/해결될 필요가 있습니다.

그런 경우에, `Depends`를 사용하여 *경로 작동 함수*의 매개변수로 선언하는 것보다 *경로 작동 데코레이터*에 `dependencies`의 `list`를 추가할 수 있습니다.

## *경로 작동 데코레이터*에 `dependencies` 추가하기

*경로 작동 데코레이터*는 `dependencies`라는 선택적인 인자를 받습니다.

`Depends()`로 된 `list`이어야합니다:
