... und haben den Code für die Tests wie zuvor.

## Testen: erweitertes Beispiel

Nun erweitern wir dieses Beispiel und fügen weitere Details hinzu, um zu sehen, wie verschiedene Teile getestet werden.

### Erweiterte **FastAPI**-Anwendungsdatei

Fahren wir mit der gleichen Dateistruktur wie zuvor fort:

      processRemaining(buffer);
      Java8Compatibility.position(buffer, buffer.limit());

    return makeHash();
  }

  /**

   * after all chunks are handled with {@link #process} and any leftover bytes that did not make a
   * complete chunk are handled with {@link #processRemaining}.

  * You do not need to adjust this flag on Kubelet:  there was no authorization for the Kubelet APIs in 1.4.
* batch/v2alpha1.ScheduledJob has been renamed, use batch/v2alpha1.CronJob instead ([#36021](https://github.com/kubernetes/kubernetes/pull/36021), [@soltysh](https://github.com/soltysh))
* PetSet has been renamed to StatefulSet.
  If you have existing PetSets, **you must perform extra migration steps** both

Up to this point, with all the tutorials in the docs, you have probably been running a **server program**, for example, using the `fastapi` command, that runs Uvicorn, running a **single process**.

            return;
          }

        }
