* Prüfen, ob es einen optionalen Query-Parameter namens `q` (wie in `http://127.0.0.1:8000/items/foo?q=somequery`) für `GET`-Requests gibt.
    * Da der `q`-Parameter mit `= None` deklariert ist, ist er optional.
    * Ohne das `None` wäre er erforderlich (wie der Body im Fall von `PUT`).
* Bei `PUT`-Requests an `/items/{item_id}` den Body als JSON lesen:
    * Prüfen, ob er ein erforderliches Attribut `name` hat, das ein `str` sein muss.

### Namenskollisionen vermeiden { #avoid-name-collisions }

Wir importieren das Submodul `items` direkt, anstatt nur seine Variable `router` zu importieren.

Das liegt daran, dass wir im Submodul `users` auch eine weitere Variable namens `router` haben.

Wenn wir eine nach der anderen importiert hätten, etwa:

```Python

            new SetMultimapTestSuiteBuilder.MultimapGetGenerator<K, V>(
                parentBuilder.getSubjectGenerator()))
        .withFeatures(computeMultimapGetFeatures(parentBuilder.getFeatures()))
        .named(parentBuilder.getName() + ".get[key]")
        .suppressing(parentBuilder.getSuppressedTests())
        .createTestSuite();
  }
