# Testing

Thanks to <a href="https://www.starlette.io/testclient/" class="external-link" target="_blank">Starlette</a>, testing **FastAPI** applications is easy and enjoyable.

It is based on <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, which in turn is designed based on Requests, so it's very familiar and intuitive.

# 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。
