如何用Junit和Mockito测试Spring验证器
如何用Junit和Mockito测试Spring验证器
提问于 2015-09-27 16:44:30
我有一个Spring Validator：
@Component
public class AddClientAccountValidator implements Validator {
@Autowired
private ValidatorUtils validatorUtils;
@Override
public boolean supports(Class<?> clazz) {
return UserDto.class.equals(clazz);
}
@Override
public void validate(Object target, Errors errors) {
UserDto user = (UserDto) target;
validatorUtils.setParam(errors, user);
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "username", "username.required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "password", "password.required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "confirmPassword",
"confirmPassword.required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "firstName", "firstName.required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "lastName", "lastName.required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "personalId", "personalId.required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "city", "city.required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "address", "address.required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "email", "email.required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "phone", "phone.required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "contribution", "contribution.required");
validatorUtils.validateAddClientAccount();
}
}在上面的验证器已经注入到ValidatorUtils类：
@Component
class ValidatorUtils {
@Autowired
private PersonalIdValidator personalIdValidator;
private Errors errors;
private UserDto user;
void setParam(Errors errors, UserDto user) {
this.errors = errors;
this.user = user;
}
void validateAddClientAccount() {
validateAccount();
validContributionAccount();
}
private void validateAccount() {
validUsername();
validPassword();
validFirstName();
validLastName();
validPersonalId();
validCity();
validAddress();
validEmail();
validPhone();
}
public void validateChangePassword() {
validChangePassword();
}
private void validUsername() {
if (!user.getUsername().isEmpty()) {
String username = user.getUsername();
if ((username.length() < 3) || (username.length() > 40)) {
errors.rejectValue("username", "username.format");
}
}
}
private void validPassword() {
if (!user.getPassword().isEmpty()) {
String password = user.getPassword();
if ((password.length() < 3) || (password.length() > 40)) {
errors.rejectValue("password", "password.format");
}
if (!password.equals(user.getConfirmPassword())) {
errors.rejectValue("confirmPassword", "password.confirm");
}
}
}
private void validFirstName() {
if (!user.getFirstName().isEmpty()) {
String firstName = user.getFirstName();
String regex = "[A-ZŁ{1}]+[a-zł]+";
boolean validFirstName = Pattern.matches(regex, firstName);
if ((firstName.length() < 3) || (firstName.length() > 40) || !validFirstName) {
errors.rejectValue("firstName", "firstName.format");
}
}
}
private void validLastName() {
if (!user.getLastName().isEmpty()) {
String lastName = user.getLastName();
String regex = "[A-ZĆŁŚŻŹ{1}]+[a-ząćęłńóśżź]+";
String regexWithTwoLastName = "[A-ZĆŁŚŻŹ{1}]+[a-ząćęłńóśżź]++[\\s]+[A-ZĆŁŚŻŹ{1}]+[a-ząćęłńóśżź]+";
boolean validLastName = Pattern.matches(regex, lastName);
boolean validWithTwoLastName = Pattern.matches(regexWithTwoLastName, lastName);
if ((lastName.length() < 3) || (lastName.length() > 40)
|| (!validLastName && !validWithTwoLastName)) {
errors.rejectValue("lastName", "lastName.format");
}
}
}这个类有更多的字段验证器，但我跳过了它。
我想使用Junit或最终使用mockito测试我的Validator类。我写这个测试类：
@RunWith(MockitoJUnitRunner.class)
public class AddClientAccValidatorTest {
@InjectMocks
private AddClientAccountValidator validator;
@Mock
private ValidatorUtils validatoUtils;
private UserDto userDto;
public Errors errors;
@Before
public void setUp() {
UserDto userDto = new UserDto();
errors = new BeanPropertyBindingResult(userDto, "userDto");
}
@Test
public void testValidate() {
validator.validate(userDto, errors);
assertFalse(errors.hasErrors());
}
}但是当我运行我的测试时，我得到以下Failet跟踪：

at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192)为什么会出现这个错误？我在这一行得到错误：
errors = new BeanPropertyBindingResult(userDto, "userDto");我的第二个问题是我不能声明多个RunWith注释。当我添加：
@RunWith(MockitoJUnitRunner.class)我不能使用@RunWith(Parameterized.class)参数化我的测试
如何解决？
有人能帮我吗？也许我的方法不好？用Junit测试Spring Validator的最佳方式是什么？

你不需要模拟任何东西。在验证时，我们需要要验证的对象和错误。创建一个包含要验证的必填字段和errors对象的对象。例如,
@Test
public void shouldReturnErrorsWhenCustomObjectIsNull() {
CustomValidator customValidator = new CustomValidator();
Employee employee = new Employee();
employee.setEmployeeFirstname("empName")
Errors errors = new BeanPropertyBindingResult(employee, "employee");
customValidator.validate(employee, errors);
List<ObjectError> allErrors = errors.getAllErrors();
assertTrue("Errors list size should not be null : ", allErrors.size() > 0);
assertTrue(errors.hasErrors());
assertNotNull( errors.getFieldError("empName") );
