Mas assim obtemos um `dict` como valor do parâmetro `commons` na *função de operação de rota*.

E sabemos que editores de texto não têm como oferecer muitas funcionalidades (como sugestões automáticas) para objetos do tipo `dict`, por que não há como eles saberem o tipo das chaves e dos valores.

Podemos fazer melhor...

## O que caracteriza uma dependência

Você verá a documentação interativa automática da API (fornecida pelo <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a>):

![Swagger UI](https://fastapi.tiangolo.com/img/index/index-01-swagger-ui-simple.png)

Danach müssen Sie nur noch `pytest` installieren:

<div class="termy">

```console
$ pip install pytest

---> 100%
```

</div>

Es erkennt die Dateien und Tests automatisch, führt sie aus und berichtet Ihnen die Ergebnisse.

Führen Sie die Tests aus, mit:

<div class="termy">

```console
$ pytest

================ test session starts ================

/// info

Even after OpenAPI 3.1.0 was released with this new simpler integration with JSON Schema, for a while, Swagger UI, the tool that provides the automatic docs, didn't support OpenAPI 3.1.0 (it does since version 5.0.0 🎉).

Because of that, versions of FastAPI previous to 0.99.0 still used versions of OpenAPI lower than 3.1.0.

///

/// check

Beachten Sie, dass der Wert, den Ihre Funktion erhält und zurückgibt, die Zahl `3` ist, also ein `int`. Nicht der String `"3"`, also ein `str`.

Sprich, mit dieser Typdeklaration wird **FastAPI** die Anfrage automatisch <abbr title="Den String, der von einer HTTP Anfrage kommt, in Python-Objekte konvertieren">„parsen“</abbr>.

## Datenvalidierung

#
#    - New environments like new CUDA versions, changes to manylinux,
#      compilers, etc. can cause undefined behavior such as build failures
#      or tests passing incorrectly.
#    - Automatic LLVM updates are known to extend build time even with
#      the cache; this is unavoidable.
