### Question:
DefaultUntypedRecordableEventDescriptor implements UntypedRecordableEventDescriptor, WikiComponent { @Override public String getTargetExpression() { return this.target; } DefaultUntypedRecordableEventDescriptor(EntityReference reference, DocumentReference authorReference,
        BaseObject baseObject, ContextualLocalizationManager contextualLocalizationManager,
            NamespaceContextExecutor namespaceContextExecutor); @Override String getValidationExpression(); @Override List<String> getEventTriggers(); @Override List<String> getObjectTypes(); @Override EntityReference getEntityReference(); @Override DocumentReference getDocumentReference(); @Override DocumentReference getAuthorReference(); @Override Type getRoleType(); @Override String getRoleHint(); @Override WikiComponentScope getScope(); @Override String getEventType(); @Override String getApplicationName(); @Override String getApplicationId(); @Override String getDescription(); @Override String getApplicationIcon(); @Override String getEventTypeIcon(); @Override String getTargetExpression();  }### Answer:
@Test public void getTargetExpression() throws Exception { assertEquals("target", descriptor.getTargetExpression()); }
