!!! tip "提示"

    `overrider_get_db()` 与 `get_db` 的代码几乎完全一样，只是 `overrider_get_db` 中使用测试数据库的 `TestingSessionLocal`。

## 测试应用

然后，就可以正常测试了。

```Python hl_lines="32-47"
{!../../../docs_src/sql_databases/sql_app/tests/test_sql_app.py!}
```

## Test the app

Then we can just test the app as normally.

```Python hl_lines="32-47"
{!../../../docs_src/sql_databases/sql_app/tests/test_sql_app.py!}
```

## Create a `websocket`

In your **FastAPI** application, create a `websocket`:

```Python hl_lines="1  46-47"
{!../../../docs_src/websockets/tutorial001.py!}
```

!!! note "Technical Details"
    You could also use `from starlette.websockets import WebSocket`.
