/// info

FastAPI added support for `Annotated` (and started recommending it) in version 0.95.0.

If you have an older version, you would get errors when trying to use `Annotated`.

Make sure you [Upgrade the FastAPI version](../deployment/versions.md#upgrading-the-fastapi-versions) to at least 0.95.1 before using `Annotated`.

///

沿用先前相同的檔案結構：

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

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：

让我们继续之前的文件结构：

```
.
├── 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`：

	_, err = obj.PutObject(ctx, bucket, object,
		mustGetPutObjReader(t, bytes.NewReader([]byte("initial-value")),
			int64(len("initial-value")), "", ""), ObjectOptions{})
	if err != nil {
		t.Fatal(err)
	}

	// Get object info to capture the ETag
	objInfo, err := obj.GetObjectInfo(ctx, bucket, object, ObjectOptions{})
	if err != nil {
		t.Fatal(err)
	}
	existingETag := objInfo.ETag

    }
