* MockWebServer. In cases where logic is particularly tricky, we use unit tests. This class makes
 * it easy to get sample values to use in such tests.
 *
 * This class is pretty fast and loose with default values: it attempts to provide values that are
 * well-formed, but doesn't guarantee values are internally consistent. Callers must take care to

Por exemplo, supondo que você está usando a versão `0.45.0` em sua aplicação.

Caso você utilize o arquivo `requirements.txt`, você poderia especificar a versão com:

```txt
fastapi==0.45.0
```

Isso significa que você conseguiria utilizar a versão exata `0.45.0`.

Ou, você poderia fixá-la com:

   * TODO(cpovirk): Is the unchecked cast avoidable? Would System.arraycopy be similarly fast (if
   * likewise not type-checked)? Could our single caller do something different?
   */

Na v1 do Pydantic ele estava incluído no pacote principal. Agora ele está distribuido como um pacote independente para que você possa optar por instalar ou não caso você não precise dessa funcionalidade.

### Criando o objeto `Settings`

Importe a classe `BaseSettings` do Pydantic e crie uma nova subclasse, de forma parecida com um modelo do Pydantic.

    timeout-minutes: 30
    if: github.ref == 'refs/heads/master' || contains(github.event.pull_request.labels.*.name, 'android') || contains(github.event.pull_request.labels.*.name, 'renovate')

    strategy:
      fail-fast: false
      matrix:
        api-level:
          - 21
          - 29
          - 34

    steps:
      - name: Checkout
        uses: actions/checkout@v4
        with:

    * Ein Beispiel ist `404`, für eine „Not Found“-Response („Nicht gefunden“).
    * Für allgemeine Fehler beim Client können Sie einfach `400` verwenden.
* `500` und darüber stehen für Server-Fehler. Diese verwenden Sie fast nie direkt. Wenn etwas an irgendeiner Stelle in Ihrem Anwendungscode oder im Server schiefläuft, wird automatisch einer dieser Fehler-Statuscodes zurückgegeben.

## Преимущества **FastAPI**

Fast API предоставляет несколько инструментов для каждой из этих схем безопасности в модуле `fastapi.security`, которые упрощают использование этих механизмов безопасности.
