* **Concis** : Diminue la duplication de code. De nombreuses fonctionnalités liées à la déclaration de chaque paramètre. Moins de bugs.

## Résultats

En utilisant uniquement les déclarations de type Python, **FastAPI** réussit à :

* Lire le contenu de la requête en tant que JSON.
* Convertir les types correspondants (si nécessaire).
* Valider la donnée.

# Variables de Entorno

/// tip | Consejo

Si ya sabes qué son las "variables de entorno" y cómo usarlas, siéntete libre de saltarte esto.

///

Una variable de entorno (también conocida como "**env var**") es una variable que vive **fuera** del código de Python, en el **sistema operativo**, y podría ser leída por tu código de Python (o por otros programas también).

   * An unmodifiable element-count pair for a multiset. The {@link Multiset#entrySet} method returns
   * a view of the multiset whose elements are of this class. A multiset implementation may return
   * Entry instances that are either live "read-through" views to the Multiset, or immutable
   * snapshots. Note that this type is unrelated to the similarly-named type {@code Map.Entry}.

In the file `main.py` you have your **FastAPI** app:


{* ../../docs_src/app_testing/main.py *}

### Testing file { #testing-file }

Then you could have a file `test_main.py` with your tests. It could live on the same Python package (the same directory with a `__init__.py` file):

``` hl_lines="5"
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

    DummyEntry<Object, Object> entry = createDummyEntry(key, hash, value, null);

    // remove absent
    assertFalse(segment.removeEntry(entry, hash, RemovalCause.COLLECTED));

    // remove live
    segment.recordWrite(entry, 1, map.ticker.read());
    table.set(0, entry);
    segment.count = 1;
    assertTrue(segment.removeEntry(entry, hash, RemovalCause.COLLECTED));
