由于测试函数现在是异步的，因此除了在测试中向 FastAPI 应用程序发送请求之外，您现在还可以调用（和使用 `await` 等待）其他 `async` 异步函数，就和您在代码中的其他任何地方调用它们的方法一样。

/// tip

如果您在测试程序中集成异步函数调用的时候遇到一个 `RuntimeError: Task attached to a different loop` 的报错（例如，使用 <a href="https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop" class="external-link" target="_blank">MongoDB 的 MotorClient</a> 时），请记住，只能在异步函数中实例化需要事件循环的对象，例如通过 `'@app.on_event("startup")` 回调函数进行初始化。
