### Question:
LQModel implements Serializable { public static String newIdentifier() { String uid = UUID.randomUUID().toString().toUpperCase(Locale.ENGLISH); String epoch = LiquidTools.tenCharEpoch(Calendar.getInstance().getTimeInMillis()); return uid + "-" + epoch; }  static String newIdentifier(); static boolean validKey(String key, boolean raiseException); static boolean validValue(Object attribute, boolean raiseException); static HashMap<String, Object> sanitizeAttributes(Map<String, Object> attributes, boolean raiseException); void save(Context context, String path); static JSONObject retriveFromFile(Context context, String path); static List<Object> toList(JSONArray array, String[] excludedKeys); abstract JSONObject toJSON();  }### Answer:
@Test public void testNewIdentifierLength() { assertEquals(47, LQModel.newIdentifier().length()); }
