### Question:
EntityUtil { public static <T extends BaseEntity> boolean isPKFieldGenerated(T entity) { boolean generated = false; Field field = getPKField(entity); if (field != null) { PK idAnnotation = field.getAnnotation(PK.class); if (idAnnotation != null) { generated = idAnnotation.generated(); } } else { throw new OpenStorefrontRuntimeException("Unable to find PK for enity: " + entity.getClass().getName(), "Check entity passed in."); } return generated; }  static void setDefaultsOnFields(Object entity); static boolean isObjectsDifferent(Object original, Object compare, boolean consumeFieldsOnly); @SuppressWarnings("unchecked") static int compareConsumeFields(Object original, Object compare); static Field getPKField(T entity); static boolean isPKFieldGenerated(T entity); static String getPKFieldValue(T entity); static Object getPKFieldObjectValue(T entity); static void updatePKFieldValue(T entity, String value); static Map<String, Object> findIdField(Class entityClass, Object id); static String getRealClassName(String className);  }### Answer:
@Test public void testIsPKFieldGenerated() { System.out.println("isPKFieldGenerated"); Component entity = new Component(); boolean expResult = true; boolean result = EntityUtil.isPKFieldGenerated(entity); assertEquals(expResult, result); System.out.println(result = EntityUtil.isPKFieldGenerated(entity)); try { result = EntityUtil.isPKFieldGenerated(null); fail("Entity cannot be null"); } catch (NullPointerException e) { } AttributeType aType = new AttributeType(); aType.setAttributeType("attribute"); aType.setActiveStatus(AttributeType.ACTIVE_STATUS); expResult = false; result = EntityUtil.isPKFieldGenerated(aType); System.out.println(result); assertEquals(expResult, result); AttributeCode aCode = new AttributeCode(); result = EntityUtil.isPKFieldGenerated(aType); System.out.println(result); assertEquals(expResult, result); }
