添加测试后，你可以将 **FastAPI** 版本升级到更新版本，并通过运行测试来确保所有代码都能正常工作。

如果一切正常，或者在进行必要的更改之后，并且所有测试都通过了，那么你可以将`fastapi`固定到新的版本。

## 关于Starlette { #about-starlette }

你不应该固定`starlette`的版本。

不同版本的 **FastAPI** 将使用特定的较新版本的 Starlette。

因此，**FastAPI** 自己可以使用正确的 Starlette 版本。

## 关于 Pydantic { #about-pydantic }

Pydantic 包含针对 **FastAPI** 的测试及其自己的测试，因此 Pydantic 的新版本（`1.0.0`以上）始终与 FastAPI 兼容。

你可以将 Pydantic 固定到任何高于 `1.0.0` 且适合你的版本。

## À propos de Starlette { #about-starlette }

Vous ne devez pas épingler la version de `starlette`.

Différentes versions de **FastAPI** utiliseront une version spécifique plus récente de Starlette.

Ainsi, vous pouvez simplement laisser **FastAPI** utiliser la bonne version de Starlette.

Some response codes (see the next section) indicate that the response does not have a body.

FastAPI knows this, and will produce OpenAPI docs that state there is no response body.

/// note

If you already know what HTTP status codes are, skip to the next section.

In HTTP, you send a numeric status code of 3 digits as part of the response.
