### Question:
ModelUtils { public static void normalizeRegionWidgetPreference(String regionWidgetId, RegionWidgetPreference regionWidgetPreference) { regionWidgetPreference.setRegionWidgetId(regionWidgetId); } private  ModelUtils(); static void normalizeRegionWidgetPreferences(String regionWidgetId, List<RegionWidgetPreference> preferences); static void normalizeRegionWidgetPreference(String regionWidgetId, RegionWidgetPreference regionWidgetPreference); static final String STANDARD_DATE_FORMAT; }### Answer:
@Test public void normalizeRegionWidgetPreference() { RegionWidgetPreference testPreference = new RegionWidgetPreferenceImpl( null, "camelCaseName", "FOO"); ModelUtils.normalizeRegionWidgetPreference(VALID_REGION_WIDGET_ID, testPreference); assertTrue(testPreference.getRegionWidgetId() == VALID_REGION_WIDGET_ID); }
