Verwenden Sie das `TestClient`-Objekt auf die gleiche Weise wie `httpx`.

Schreiben Sie einfache `assert`-Anweisungen mit den Standard-Python-Ausdrücken, die Sie überprüfen müssen (wiederum, Standard-`pytest`).

Beachten Sie, dass die Testfunktionen normal `def` und nicht `async def` sind.

第一步是安裝 FastAPI。

確保你建立一個[虛擬環境](../virtual-environments.md){.internal-link target=_blank}，啟用它，然後**安裝 FastAPI**：

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// note

當你使用 `pip install "fastapi[standard]"` 安裝時，會包含一些預設的可選標準依賴項。

如果你不想包含那些可選的依賴項，你可以使用 `pip install fastapi` 來安裝。

/// tip

Notice that in this case we are using a standard Python `open()` function that interacts with a file.

So, it involves I/O (input/output), that requires "waiting" for things to be written to disk.

But `open()` doesn't use `async` and `await`.

So, we declare the event handler function with standard `def` instead of `async def`.

In diesem Beispiel wird das Pydantic-Modell in ein `dict`, und das `datetime`-Objekt in ein `str` konvertiert.
