ASGI é um novo "padrão" sendo desenvolvido pelos membros do time central do Django. Ele ainda não está como "Padrão Python" (PEP), embora eles estejam em processo de fazer isso.

If you want to call `async` functions in your tests apart from sending requests to your FastAPI application (e.g. asynchronous database functions), have a look at the [Async Tests](../advanced/async-tests.md){.internal-link target=_blank} in the advanced tutorial.

## Separating tests

```console
$ pip install python-multipart
```

This is because **OAuth2** uses "form data" for sending the `username` and `password`.

Run the example with:

<div class="termy">

```console
$ fastapi dev main.py

Network isolation between different models is also important not only to prevent
unauthorized access to data or models, but also to prevent malicious users or
tenants sending graphs to execute under another tenant’s identity.

The isolation mechanisms are the responsibility of the users to design and
implement, and therefore security issues deriving from their absence are not

## Futuro

Nesse ponto, já está claro que o **FastAPI** com suas ideias está sendo útil para muitas pessoas.

Ele foi escolhido sobre outras alternativas anteriores por se adequar melhor em muitos casos.

Muitos desenvolvedores e times já dependem do **FastAPI** para seus projetos (incluindo eu e meu time).

   * This method returns false unless it is overridden by a subclass.
   *
   * ### Duplex Transmission
   *
   * With regular HTTP calls the request always completes sending before the response may begin
   * receiving. With duplex the request and response may be interleaved! That is, request body bytes
   * may be sent after response headers or body bytes have been received.

/// info

To send data, you should use one of: `POST` (the more common), `PUT`, `DELETE` or `PATCH`.

Sending a body with a `GET` request has an undefined behavior in the specifications, nevertheless, it is supported by FastAPI, only for very complex/extreme use cases.
