### Question:
ValidationUtil { public static boolean isValid(ValidationModel validateModel) { return validate(validateModel).valid(); } private  ValidationUtil(); static boolean isValid(ValidationModel validateModel); @SuppressWarnings("unchecked") static ValidationResult validate(ValidationModel validateModel); static void setSkipValidationForTesting(boolean aSkipValidationForTesting);  }### Answer:
@Test public void testIsValid() { System.out.println("isValid"); UserTypeCode userTypeCode = new UserTypeCode(); userTypeCode.setCode("Test"); userTypeCode.setDescription("Test Description"); ValidationModel validateModel = new ValidationModel(userTypeCode); validateModel.setConsumeFieldsOnly(true); boolean expResult = true; boolean result = ValidationUtil.isValid(validateModel); assertEquals(expResult, result); validateModel = new ValidationModel(userTypeCode); expResult = false; result = ValidationUtil.isValid(validateModel); assertEquals(expResult, result); EmailAddress ea = new EmailAddress(); ea.setEmail("test_testEmail@company.com"); ea.setStorageVersion("3.1.2"); validateModel = new ValidationModel(ea); expResult = true; result = ValidationUtil.isValid(validateModel); assertEquals(expResult, result); }
