Previous versions of Starlette included a `GraphQLApp` class to integrate with <a href="https://graphene-python.org/" class="external-link" target="_blank">Graphene</a>.

It was deprecated from Starlette, but if you have code that used it, you can easily **migrate** to <a href="https://github.com/ciscorn/starlette-graphene3" class="external-link" target="_blank">starlette-graphene3</a>, that covers the same use case and has an **almost identical interface**.

There were even some changes to Pydantic itself to support this.

The previous screenshots were taken with <a href="https://code.visualstudio.com" class="external-link" target="_blank">Visual Studio Code</a>.

But you would get the same editor support with <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a> and most of the other Python editors:

```

Декоратор `@app.get("/")` указывает **FastAPI**, что функция, прямо под ним, отвечает за обработку запросов, поступающих по адресу:

* путь `/`
* использующих <abbr title="HTTP GET метод"><code>get</code> операцию</abbr>

/// info | "`@decorator` Дополнительная информация"

Синтаксис `@something` в Python называется "декоратор".

```

////

FastAPI will use this return type to:

* **Validate** the returned data.
    * If the data is invalid (e.g. you are missing a field), it means that *your* app code is broken, not returning what it should, and it will return a server error instead of returning incorrect data. This way you and your clients can be certain that they will receive the data and the data shape expected.

```

... und haben den Code für die Tests wie zuvor.

## Testen: erweitertes Beispiel

Nun erweitern wir dieses Beispiel und fügen weitere Details hinzu, um zu sehen, wie verschiedene Teile getestet werden.
