/// tip | Consejo

Tener el modelo de retorno asegurando que un valor siempre esté disponible y siempre sea `int` (no `None`) es muy útil para los clientes de la API, pueden escribir código mucho más simple teniendo esta certeza.

cd ..

LOG_FILE=$BASE_DIR/test.log

mvn test > $LOG_FILE 2>&1
ret=$?

if [ $ret != 0 ] ; then
  for f in `find $BASE_DIR -type f | grep surefire-reports | grep -v /TEST-` ; do
    cat $f
  done
fi

### Предупреждение о замене

Это означает, что если вы хотите обновить элемент `bar`, используя `PUT` с телом, содержащим:

```Python
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

поскольку оно не включает уже сохраненный атрибут `"tax": 20.2`, входная модель примет значение по умолчанию `"tax": 10.5`.

И данные будут сохранены с этим "новым" `tax`, равным `10,5`.

 * `::1` will reach the IPv6 server.
 *
 * By orchestrating two different servers with the same port but different IP addresses, we can
 * test what OkHttp does when both are reachable, or if only one is reachable.
 *
 * This test only runs on host machines that have both IPv4 and IPv6 addresses for localhost.

@Timeout(30)
class FastFallbackTest {
  @RegisterExtension
  val clientTestRule = OkHttpClientTestRule()

In this case, it would be better to get **one extra server** and run some processes on it so that they all have **enough RAM and CPU time**.
