## Codegröße { #code-size }

Dieses Beispiel mag ausführlich erscheinen. Bedenken Sie, dass wir Sicherheit, Datenmodelle, Hilfsfunktionen und *Pfadoperationen* in derselben Datei vermischen.

Aber hier ist der entscheidende Punkt.

Der Code für Sicherheit und Dependency Injection wird einmal geschrieben.

    // Make sure that hash codes are not computed per-instance.
    assertEqualHashCode(Predicates.not(p1), Predicates.not(p1));

    assertEqualHashCode(Predicates.and(p1, p2), Predicates.and(p1, p2));

    assertEqualHashCode(Predicates.or(p1, p2), Predicates.or(p1, p2));

    // While not a contractual requirement, we'd like the hash codes for ands
    // & ors of the same predicates to not collide.

from sqlmodel.main import default_registry

from tests.utils import needs_py310


def clear_sqlmodel():
    # Clear the tables in the metadata for the default base model
    SQLModel.metadata.clear()
    # Clear the Models associated with the registry, to avoid warnings
    default_registry.dispose()


@pytest.fixture(
    name="client",
    params=[
        pytest.param("tutorial001_py39"),

Não estamos restritos a ter apenas uma dependência que possa retornar esse tipo de dado.

///

## Outros modelos { #other-models }

Agora você pode obter o usuário atual diretamente nas *funções de operação de rota* e lidar com os mecanismos de segurança no nível da **Injeção de Dependências**, usando `Depends`.

             the following code:

    /** Preferred lease version (1 or 2) */
    protected int leaseVersion = 2;
    /** Lease break timeout in seconds (per MS-SMB2 spec) */
    protected int leaseBreakTimeout = 60;

```console
$ pip install httpx

Importe `TestClient`.

Crie um `TestClient` passando sua aplicação **FastAPI** para ele.

Crie funções com um nome que comece com `test_` (essa é a convenção padrão do `pytest`).

Use o objeto `TestClient` da mesma forma que você faz com `httpx`.

Sie können also weiterhin die `HTTPException` von **FastAPI** wie üblich in Ihrem Code auslösen.

Aber wenn Sie einen Exceptionhandler registrieren, sollten Sie ihn für die `HTTPException` von Starlette registrieren.
