You can read more about this in the [Advanced User Guide](../advanced/index.md){.internal-link target=_blank}.

## Details

The first `"/static"` refers to the sub-path this "sub-application" will be "mounted" on. So, any path that starts with `"/static"` will be handled by it.

The `directory="static"` refers to the name of the directory that contains your static files.

The `name="static"` gives it a name that can be used internally by **FastAPI**.

    E.g. `pip install httpx`.

Import `TestClient`.

Create a `TestClient` by passing your **FastAPI** application to it.

Create functions with a name that starts with `test_` (this is standard `pytest` conventions).

Use the `TestClient` object the same way as you do with `httpx`.

Enquanto você espera, você vai com seu _crush_ :heart_eyes: e pega uma mesa, senta e conversa com seu _crush_ :heart_eyes: por um bom tempo (como seus hambúrgueres são muito saborosos, leva um tempo para serem preparados).

Enquanto você está sentado na mesa com seu _crush_ :heart_eyes:, esperando os hambúrgueres, você pode gastar o tempo admirando como lindo, maravilhoso e esperto é seu _crush_ :heart_eyes:.

And if your remote server or virtual machine only has 3 GB of RAM, trying to load more than 4 GB of RAM will cause problems. 🚨

### Multiple Processes - An Example

In this example, there's a **Manager Process** that starts and controls two **Worker Processes**.

This Manager Process would probably be the one listening on the **port** in the IP. And it would transmit all the communication to the worker processes.

!!! note
    Notice the header `Authorization`, with a value that starts with `Bearer `.

## Advanced usage with `scopes`

OAuth2 has the notion of "scopes".

You can use them to add a specific set of permissions to a JWT token.

Die Hauptfunktion, die ich vom Django REST Framework haben wollte, war die automatische API-Dokumentation.

Dann fand ich heraus, dass es einen Standard namens Swagger gab, zur Dokumentation von APIs unter Verwendung von JSON (oder YAML, einer Erweiterung von JSON).

    ```Python hl_lines="11"
    {!> ../../../docs_src/query_params_str_validations/tutorial004.py!}
    ```

This specific regular expression pattern checks that the received parameter value:

* `^`: starts with the following characters, doesn't have characters before.
* `fixedquery`: has the exact value `fixedquery`.
* `$`: ends there, doesn't have any more characters after `fixedquery`.

Запустите тесты командой `pytest` и увидите результат:

<div class="termy">

```console
$ pytest
