# 测试数据库

您还可以使用[测试依赖项](testing-dependencies.md){.internal-link target=_blank}中的覆盖依赖项方法变更测试的数据库。

实现设置其它测试数据库、在测试后回滚数据、或预填测试数据等操作。

本章的主要思路与上一章完全相同。

## 为 SQL 应用添加测试

为了使用测试数据库，我们要升级 [SQL 关系型数据库](../tutorial/sql-databases.md){.internal-link target=_blank} 一章中的示例。

应用的所有代码都一样，直接查看那一章的示例代码即可。

本章只是新添加了测试文件。

正常的依赖项 `get_db()` 返回数据库会话。

测试时使用覆盖依赖项返回自定义数据库会话代替正常的依赖项。

本例中，要创建仅用于测试的临时数据库。

# Events testen: Hochfahren – Herunterfahren

Wenn Sie in Ihren Tests Ihre Event-Handler (`startup` und `shutdown`) ausführen wollen, können Sie den `TestClient` mit einer `with`-Anweisung verwenden:

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

<module>
<source path="">
  <!-- Hack to keep collect from hiding collect.testing supersource: -->
  <exclude name="**/testing/**"/>
</source>

<!--
    We used to set this only for packages that had manual supersource. That
    worked everywhere that I know of except for one place: when running the GWT
    util.concurrent tests under Guava.

    The problem is that GWT responds poorly to two .gwt.xml files in the same

# Testing WebSockets

You can use the same `TestClient` to test WebSockets.

For this, you use the `TestClient` in a `with` statement, connecting to the WebSocket:

```
