After you have tests, then you can upgrade the **FastAPI** version to a more recent one, and make sure that all your code is working correctly by running your tests.

If everything is working, or after you make the necessary changes, and all your tests are passing, then you can pin your `fastapi` to that new recent version.

## About Starlette { #about-starlette }

You shouldn't pin the version of `starlette`.

Notice that `response_description` refers specifically to the response, the `description` refers to the *path operation* in general.

OpenAPI specifies that each *path operation* requires a response description.
