Security is very important for FastAPI and its community. 🔒

Learn more about it below. 👇

## Versions

The latest version of FastAPI is supported.

You are encouraged to [write tests](https://fastapi.tiangolo.com/tutorial/testing/) for your application and update your FastAPI version frequently after ensuring that your tests are passing. This way you will benefit from the latest features, bug fixes, and **security fixes**.

## Upgrade der FastAPI-Versionen

Sie sollten Tests für Ihre Anwendung hinzufügen.

Mit **FastAPI** ist das sehr einfach (dank Starlette), schauen Sie sich die Dokumentation an: [Testen](../tutorial/testing.md){.internal-link target=_blank}

All in a way that provided the best development experience for all the developers.

## Requirements

After testing several alternatives, I decided that I was going to use <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">**Pydantic**</a> for its advantages.

# Testing Dependencies with Overrides

## Overriding dependencies during testing

There are some scenarios where you might want to override a dependency during testing.

You don't want the original dependency to run (nor any of the sub-dependencies it might have).
