# 测试事件：启动 - 关闭

使用 `TestClient` 和 `with` 语句，在测试中运行事件处理器（`startup` 与 `shutdown`）。

```Python hl_lines="9-12  20-24"
{!../../../docs_src/app_testing/tutorial003.py!}

# Testing Events: startup - shutdown

When you need your event handlers (`startup` and `shutdown`) to run in your tests, you can use the `TestClient` with a `with` statement:

```Python hl_lines="9-12  20-24"
{!../../../docs_src/app_testing/tutorial003.py!}

    {!> ../../../docs_src/response_model/tutorial003.py!}
    ```

这样，即便我们的*路径操作函数*将会返回包含密码的相同输入用户：

=== "Python 3.10+"

    ```Python hl_lines="24"
    {!> ../../../docs_src/response_model/tutorial003_py310.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="24"
    {!> ../../../docs_src/response_model/tutorial003.py!}
    ```

...我们已经将 `response_model` 声明为了不包含密码的 `UserOut` 模型：

=== "Python 3.10+"

Here, even though our *path operation function* is returning the same input user that contains the password:

=== "Python 3.10+"

    ```Python hl_lines="24"
    {!> ../../../docs_src/response_model/tutorial003_py310.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="24"
    {!> ../../../docs_src/response_model/tutorial003.py!}
    ```

代わりに、平文のパスワードを持つ入力モデルと、パスワードを持たない出力モデルを作成することができます:

```Python hl_lines="9 11 16"
{!../../../docs_src/response_model/tutorial003.py!}
```

ここでは、*path operation関数*がパスワードを含む同じ入力ユーザーを返しているにもかかわらず:

```Python hl_lines="24"
{!../../../docs_src/response_model/tutorial003.py!}
```

...`response_model`を`UserOut`と宣言したことで、パスワードが含まれていません:

```Python hl_lines="22"
{!../../../docs_src/response_model/tutorial003.py!}
```

    ```

=== "Python 3.9+"

    ```Python hl_lines="23"
    {!> ../../../docs_src/dependencies/tutorial005_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="24"
    {!> ../../../docs_src/dependencies/tutorial005_an.py!}
    ```

=== "Python 3.10 nicht annotiert"

    !!! tip "Tipp"
        Bevorzugen Sie die `Annotated`-Version, falls möglich.

```Python hl_lines="12-21"
{!../../../docs_src/nosql_databases/tutorial001.py!}
```

### Das OpenAPI-Schema ändern

Jetzt können Sie die ReDoc-Erweiterung hinzufügen und dem `info`-„Objekt“ im OpenAPI-Schema ein benutzerdefiniertes `x-logo` hinzufügen:

```Python hl_lines="22-24"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### Zwischenspeichern des OpenAPI-Schemas

Sie können die Eigenschaft `.openapi_schema` als „Cache“ verwenden, um Ihr generiertes Schema zu speichern.
