因為這個檔案在同一個套件中，你可以使用相對匯入，從 `main` 模組（`main.py`）匯入 `app` 這個物件：

{* ../../docs_src/app_testing/app_a_py310/test_main.py hl[3] *}


...然後測試的程式碼就和先前一樣。

## 測試：進階範例 { #testing-extended-example }

現在我們延伸這個範例並加入更多細節，看看如何測試不同部分。

### 擴充的 **FastAPI** 應用檔案 { #extended-fastapi-app-file }

沿用先前相同的檔案結構：

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py

Callback'in gerçek kodu, büyük ölçüde sizin API uygulamanıza bağlıdır.

Ve bir uygulamadan diğerine oldukça değişebilir.

Sadece bir-iki satır kod bile olabilir, örneğin:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"
httpx.post(callback_url, json={"description": "Invoice paid", "paid": True})
```

│   └── test_main.py
```

因为这文件在同一个包中，所以你可以通过相对导入从 `main` 模块（`main.py`）导入`app`对象：

{* ../../docs_src/app_testing/app_a_py310/test_main.py hl[3] *}

...然后测试代码和之前一样的。

## 测试：扩展示例 { #testing-extended-example }

现在让我们扩展这个例子，并添加更多细节，看下如何测试不同部分。

### 扩展后的 **FastAPI** app 文件 { #extended-fastapi-app-file }

让我们继续之前的文件结构：

```
.
├── app
│   ├── __init__.py
│   ├── main.py

## Resumen { #recap }

- Favour a working external library if appropriate.  There are many examples of OkHttp libraries that can sit on top or hook in via existing APIs.
- Get working code on a personal branch with tests before you submit a PR.

     * <p>
     * When copying between JavaBeans and {@link Map}, you can change the delimiter used in property names.
     * For example, if you specify an underscore as the delimiter for JavaBeans and a period as the delimiter for {@link Map},
     * the property names for the source and destination will be as follows:
