### Return a Response Directly

The most common case would be [returning a Response directly as explained later in the advanced docs](../advanced/response-directly.md){.internal-link target=_blank}.

```Python hl_lines="8  10-11"
{!> ../../docs_src/response_model/tutorial003_02.py!}
```

the corresponding code point.  If the iteration encounters an invalid
UTF-8 sequence, the second value will be <code>0xFFFD</code>,
the Unicode replacement character, and the next iteration will advance
a single byte in the string.
</li>

<li>
The iteration order over maps is not specified
and is not guaranteed to be the same from one iteration to the next.

The same way, you could raise an `HTTPException` or similar in the exit code, after the `yield`.

/// tip

This is a somewhat advanced technique, and in most of the cases you won't really need it, as you can raise exceptions (including `HTTPException`) from inside of the rest of your application code, for example, in the *path operation function*.

### Criar uma classe `GzipRequest` personalizada

/// tip | Dica

Isso é um exemplo de brincadeira para demonstrar como funciona, se você precisar de suporte para Gzip, você pode usar o [`GzipMiddleware`](../advanced/middleware.md#gzipmiddleware){.internal-link target=_blank} fornecido.

/// tip | "Tipp"

Wenn Sie in Ihren Tests neben dem Senden von Anfragen an Ihre FastAPI-Anwendung auch `async`-Funktionen aufrufen möchten (z. B. asynchrone Datenbankfunktionen), werfen Sie einen Blick auf die [Async-Tests](../advanced/async-tests.md){.internal-link target=_blank} im Handbuch für fortgeschrittene Benutzer.

///

## Tests separieren

In einer echten Anwendung würden Sie Ihre Tests wahrscheinlich in einer anderen Datei haben.

Если для тестирования Вам, помимо запросов к приложению FastAPI, необходимо вызывать асинхронные функции (например, для подключения к базе данных с помощью асинхронного драйвера), то ознакомьтесь со страницей [Асинхронное тестирование](../advanced/async-tests.md){.internal-link target=_blank} в расширенном руководстве.

## Разделение тестов и приложения

В реальном приложении Вы, вероятно, разместите тесты в отдельном файле.

Meer informatie over het gebruik van omgevingsvariabelen voor het verwerken van **applicatie instellingen** vind je in de [Geavanceerde gebruikershandleiding - Instellingen en Omgevingsvariabelen](./advanced/settings.md){.internal-link target=_blank}.

## `PATH` Omgevingsvariabele

sure your code compiles by running `./gradlew check`. Checkstyle failures
during compilation indicate errors in your style and can be viewed in the
`checkstyle-result.xml` file.

Some general advice

- Don’t change public API lightly, avoid if possible, and include your reasoning in the PR if essential.  It causes pain for developers who use OkHttp and sometimes runtime errors.
