Wie funktioniert das? Schauen wir uns das mal an. 🤓

### Typannotationen und Tooling

Sehen wir uns zunächst an, wie Editor, mypy und andere Tools dies sehen würden.

`BaseUser` verfügt über die Basis-Felder. Dann erbt `UserIn` von `BaseUser` und fügt das Feld `Passwort` hinzu, sodass dass es nun alle Felder beider Modelle hat.

// Special test type for test with directories
type objTestTypeWithDirs func(obj ObjectLayer, instanceType string, dirs []string, t TestErrHandler)

// Special object test type for disk not found situations.
type objTestDiskNotFoundType func(obj ObjectLayer, instanceType string, dirs []string, t *testing.T)

// ExecObjectLayerTest - executes object layer tests.

    CacheBuilder<Object, Object> builder = CacheBuilder.newBuilder().maximumSize(16);
    assertThrows(IllegalStateException.class, () -> builder.maximumWeight(16));
  }

  @GwtIncompatible // digs into internals of the non-GWT implementation
  public void testMaximumSize_largerThanInt() {
    CacheBuilder<Object, Object> builder =
        CacheBuilder.newBuilder().initialCapacity(512).maximumSize(Long.MAX_VALUE);

    CacheBuilder<Object, Object> builder = CacheBuilder.newBuilder().maximumSize(16);
    assertThrows(IllegalStateException.class, () -> builder.maximumWeight(16));
  }

    * Prüfen, ob er ein erforderliches Attribut `price` hat, das ein `float` sein muss.
    * Prüfen, ob er ein optionales Attribut `is_offer` hat, das ein `bool` sein muss, falls vorhanden.
    * All dies würde auch für tief verschachtelte JSON-Objekte funktionieren.
* Automatisch von und nach JSON konvertieren.
* Alles mit OpenAPI dokumentieren, welches verwendet werden kann von:
    * Interaktiven Dokumentationssystemen.
