**FastAPI** 提供了和 `starlette.testclient` 一样的 `fastapi.testclient`，只是为了方便开发者。但它直接来自Starlette。

///

/// tip | "提示"

除了发送请求之外，如果你还想测试时在FastAPI应用中调用 `async` 函数（例如异步数据库函数）， 可以在高级教程中看下 [Async Tests](../advanced/async-tests.md){.internal-link target=_blank} 。

## 分离测试

在实际应用中，你可能会把你的测试放在另一个文件里。

您的**FastAPI**应用程序也可能由一些文件/模块组成等等。
