   * To avoid the need to call requireNonNull so much, we could consider more clever approaches,
   * such as:
   *
   * - Make checkOpen return the non-null `seq`. Then callers can assign that to a local variable or
   *   even back to `this.seq`. However, that may suggest that we're defending against concurrent
   *   mutation, which is not an actual risk because we use `synchronized`.

 * an expressive source hint for the model problem. Instead, the source hint is configured by the model builder before
 * it delegates to other components that potentially encounter problems. Then, the problem reporter can focus on
 * providing a simple error message, leaving the donkey work of creating a nice model problem to this component.
 *
 * @deprecated use {@code org.apache.maven.api.services.ModelBuilder} instead

假設現在你的 **FastAPI** 應用所在的 `main.py` 有一些其他的路徑操作（path operations）。

它有一個可能回傳錯誤的 `GET` 操作。

它有一個可能回傳多種錯誤的 `POST` 操作。

兩個路徑操作都需要一個 `X-Token` 標頭（header）。

{* ../../docs_src/app_testing/app_b_an_py310/main.py *}

### 擴充的測試檔案 { #extended-testing-file }

接著你可以把 `test_main.py` 更新為擴充後的測試：

{* ../../docs_src/app_testing/app_b_an_py310/test_main.py *}

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

假设现在包含**FastAPI** app的文件 `main.py` 有些其他**路径操作**。

有个 `GET` 操作会返回错误。

有个 `POST` 操作会返回一些错误。

所有*路径操作* 都需要一个`X-Token` 头。

{* ../../docs_src/app_testing/app_b_an_py310/main.py *}

### 扩展后的测试文件 { #extended-testing-file }

然后您可以使用扩展后的测试更新`test_main.py`：

{* ../../docs_src/app_testing/app_b_an_py310/test_main.py *}
