### Question:
NotificationTypeDateConverter implements Converter<NotificationType, String> { @Override public String toWidgetValue(NotificationType modelValue) { return modelValue.getType(); }  @Override Class<NotificationType> getModelType(); @Override NotificationType toModelValue(String widgetValue); @Override Class<String> getComponentType(); @Override String toWidgetValue(NotificationType modelValue);  }### Answer:
@Test public void toWidgetValueTest() { Assert.assertEquals(NotificationType.NOT_STARTED_NOTIFY.getType(), notificationTypeDateConverter.toWidgetValue(NotificationType.NOT_STARTED_NOTIFY)); Assert.assertEquals(NotificationType.NOT_COMPLETED_NOTIFY.getType(), notificationTypeDateConverter.toWidgetValue(NotificationType.NOT_COMPLETED_NOTIFY)); }
