Pero en algunos casos necesitas devolver un código de estado diferente al predeterminado.

## Caso de uso { #use-case }

Por ejemplo, imagina que quieres devolver un código de estado HTTP de "OK" `200` por defecto.

Pero si los datos no existieran, quieres crearlos y devolver un código de estado HTTP de "CREATED" `201`.

* y la aplicación no tiene ninguna autenticación, espera que cualquier request de la misma red sea confiable.

## Ejemplo de ataque { #example-attack }

Imagina que construyes una forma de ejecutar un agente de IA local.

Provee un API en

```
http://localhost:8000/v1/agents/multivac
```

También hay un frontend en

```
http://localhost:8000
```

**Concurrency** and **parallelism** both relate to "different things happening more or less at the same time".

But the details between *concurrency* and *parallelism* are quite different.

To see the difference, imagine the following story about burgers:

### Concurrent Burgers { #concurrent-burgers }

You go with your crush to get fast food, you stand in line while the cashier takes the orders from the people in front of you. 😍

All the dependencies we have seen are a fixed function or class.

But there could be cases where you want to be able to set parameters on the dependency, without having to declare many different functions or classes.

Let's imagine that we want to have a dependency that checks if the query parameter `q` contains some fixed content.

But we want to be able to parameterize that fixed content.

## A "callable" instance { #a-callable-instance }

Imaginez que vous êtes l'ordinateur / le programme 🤖 dans cette histoire.

          .that(returnType.getComponentType())
          .isEqualTo(annotationClass.getDeclaringClass());
    }

  // This is public so that tests for Feature enums we haven't yet imagined
  // can reuse it.
  public static <E extends Enum<?> & Feature<?>> void assertGoodFeatureEnum(
      Class<E> featureEnumClass) {
    Class<?>[] classes = featureEnumClass.getDeclaredClasses();

Pouvoir utiliser des fonctions asynchrones dans vos tests peut être utile, par exemple lorsque vous interrogez votre base de données de manière asynchrone. Imaginez que vous vouliez tester l'envoi de requêtes à votre application FastAPI puis vérifier que votre backend a bien écrit les bonnes données dans la base, tout en utilisant une bibliothèque de base de données asynchrone.

        companies, or even industries — utilities useful for a sizable proportion of all Java
        programmers everywhere. If you can give enough detail such that any of us can imagine coming
        across a similar need in our own work, that's extremely helpful in studying how broadly
        useful the proposed change will be.

* and the application doesn't have any authentication, it expects that any request from the same network can be trusted.

## Example Attack { #example-attack }

Imagine you build a way to run a local AI agent.

It provides an API at

```
http://localhost:8000/v1/agents/multivac
```

There's also a frontend at

```
http://localhost:8000
