多虧了 [Starlette](https://www.starlette.dev/testclient/)，測試 **FastAPI** 應用既簡單又好用。

它是基於 [HTTPX](https://www.python-httpx.org) 打造，而 HTTPX 的設計又參考了 Requests，所以用起來非常熟悉、直覺。

借助它，你可以直接用 [pytest](https://docs.pytest.org/) 來測試 **FastAPI**。

## 使用 `TestClient` { #using-testclient }

/// info

要使用 `TestClient`，請先安裝 [`httpx`](https://www.python-httpx.org)。

請先建立並啟用一個[虛擬環境](../virtual-environments.md)，然後安裝，例如：

```console
$ pip install httpx
```

https://yourapi.com/invoices/?callback_url=https://www.external.org/events
```

ve JSON body şu şekilde olursa:

```JSON
{
    "id": "2expen51ve",
    "customer": "Mr. Richie Rich",
    "total": "9999"
}
```

o zaman sizin API'niz faturayı işleyecek ve daha sonra bir noktada `callback_url`'ye (yani *external API*'ye) bir callback request gönderecek:

```
https://www.external.org/events/invoices/2expen51ve
```

感谢 [Starlette](https://www.starlette.dev/testclient/)，测试**FastAPI** 应用轻松又愉快。

它基于 [HTTPX](https://www.python-httpx.org)，而HTTPX又是基于Requests设计的，所以很相似且易懂。

有了它，你可以直接与**FastAPI**一起使用 [pytest](https://docs.pytest.org/)。

## 使用 `TestClient` { #using-testclient }

/// info | 信息

要使用 `TestClient`，先要安装 [`httpx`](https://www.python-httpx.org)。

确保你创建并激活一个[虚拟环境](../virtual-environments.md)，然后再安装，例如：

```console
$ pip install httpx
```
