I have been trying to unit test (without running Spring container) my custom constraint annotations, but when I run my tests the NullPointerException is thrown and I don't have any clue why this is happening.
The NullPointerException is pointing out that this.validator = null in Validator class.
I was following that answer https://stackoverflow.com/a/41671471/9377513 when writing my test. But I don't know why this approach do not work in my case.
The whole exception that has been thrown during the test:
java.lang.NullPointerException: Cannot invoke "javax.validation.Validator.validate(Object, java.lang.Class[])" because "this.validator" is null

My custom constraint annotation:
#Target({ElementType.FIELD, ElementType.ANNOTATION_TYPE})
#Retention(RetentionPolicy.RUNTIME)
#NotNull
#NotEmpty
#NotBlank
#Size(min = 1, max = 5)
#Constraint(validatedBy = {AddressCheckValidator.class})
public #interface AddressCheck {
String message() default "Please provide a valid String with length min=1 and max=5";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
}
My custom constraint validator:
public class AddressCheckValidator implements ConstraintValidator<AddressCheck, String> {
#Override
public boolean isValid(String s, ConstraintValidatorContext constraintValidatorContext) {
return s != null && !s.isEmpty() && !s.isBlank() && s.length() <= 5;
}
}
And my test class:
public class AddressCheckTest {
private Validator validator;
#Before
public void setUp() {
validator = Validation.buildDefaultValidatorFactory().getValidator();
}
#ParameterizedTest
#ValueSource(strings = {"a", "ab", "abc", "abcd", "abcde"})
public void addressCheckWithinRangeTest(String value) {
var addressCheck = new AddressCheckFieldTest(value);
Set<ConstraintViolation<AddressCheckFieldTest>> violations = validator.validate(addressCheck);
assertTrue(violations.isEmpty());
}
private static class AddressCheckFieldTest {
#AddressCheck
private String addressField;
public AddressCheckFieldTest(String addressField) {
this.addressField = addressField;
}
public String getAddressField() {
return addressField;
}
public void setAddressField(String addressField) {
this.addressField = addressField;
}
}
}
As long as it is a test, you need to annotate the test class with #SpringBootTest to boot up the container and autowire the Validator correctly using #Autowired annotation.
#SpringBootTest
public class AddressCheckTest {
#Autowired
private Validator validator;
// the rest of the code
}

I have something like the following class:
public class MyService {
private static DateTimeFormatter outputFormatter = DateTimeFormatter.ofPattern("uuuu-MM-dd");
private String reformatDate(String date) {
String localDate = date;
if(localDate != null)
localDate = outputFormatter.format(ZonedDateTime.parse(localDate));
return localDate;
}
}
,and this junit:
import org.junit.jupiter.api.Test;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import static org.junit.Assert.assertEquals;
Class MyServiceTest {
private static MyService myService = new MyService();
#Test
void testReformatDate() throws NoSuchMethodException, IllegalAccessException, InvocationTargetException {
String testDate = "2022-11-30T14:16:19.449Z";
assertEquals("2022-11-30", getReformatDateMethod().invoke(testDate));
}
private Method getReformatDateMethod() throws NoSuchMethodException {
Class[] cArg = new Class[1];
cArg[0] = String.class;
Method method = myService.getClass().getDeclaredMethod("reformatDate", cArg);
method.setAccessible(true);
return method;
}
}
When the invoke is called, I get this exception:

As per suggestion from Mr. Kuhn, this works:
assertEquals("2022-11-30", getReformatDateMethod().invoke(myService, testDate));
I have a method with such signature in a UserResource.java (which is a rest controller) which I'm trying to test:
#GetMapping
#PreAuthorize("hasAuthority('view_users')")
public ResponseEntity<List<UserPaginationResponse>> getUsers(#AuthenticationPrincipal UserPrincipal userPrincipal,
#Valid #SkipLimit PaginationParams paginationParams,
#RequestParam(required = false) #Size(min = 1) String search,
#RequestParam(required = false, defaultValue = "FULL_NAME")
#EnumValue(enumClass = UserOrderField.class, ignoreCase = true) String orderField,
#RequestParam(required = false, defaultValue = "ASC")
#EnumValue(enumClass = Direction.class, ignoreCase = true) String orderType,
#RequestParam(required = false)
#EnumValue(enumClass = UserStatus.class, ignoreCase = true) String status) {
The key moment here is that #AuthenticationPrincipal (which we have a custom class for) is passed as a method argument.
What I'm doing in my test is that I autowired my UserResourse into a test class and an trying to call the getUsers method
#Sql({"/data.sql"})
class UserResourceIntegrationTest extends AbstractTestcontainersTest {
private static final long USER_ID = 102L;
private static final long ORGANIZATION_ID = 106L;
#Autowired
private UserResource userResource;
#Test
void getUsersSuccessfulTest() throws Exception {
UserPrincipal userPrincipal = new UserPrincipal(USER_ID, ORGANIZATION_ID, Role.ADMIN, Collections.emptyList());
var responseEntity = userResource.getUsers(userPrincipal, new PaginationParams(), "", "CREATED_AT", "ASC", "ACTIVE");
List<UserPaginationResponse> users = responseEntity.getBody();
}
}
it fails with a following exception:

I understand that it might not be as simple as just passing a constructed User object as #AuthenticationPrincipal, that Spring cannot resolve it properly, but how to make it work? Is it possible at all to call a controller method like that or should I be looking into using MockMvc calls?
After little searching I tried to annotate my test method with #WithMockUser annotation from spring-security-test but it fails with another exception:

Has anyone tried to call controller methods directly instead of using MockMvc?
Please take a look here. Spring security comes with proper testing support. I have shared link for section dedicated to test support for Security.
Example:
#Test
#WithMockUser(username="admin",roles={"USER","ADMIN"})
public void getMessageWithMockUserCustomUser() {
String message = messageService.getMessage();
...
}
This is how you apply test annotations on a class.
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration
#WithMockUser(username="admin",roles={"USER","ADMIN"})
public class WithMockUserTests {
}
I woluld like to test very simple class:
#Component
#RequiredArgsConstructor
public class DefaultParcelSizeMapper implements ParcelSizeMapper {
private final ParcelValidationProperties properties;
#Override
public ParcelSize toParcelSize(String parcelSize) {
if (parcelSize == null) {
return null;
}
parcelSize = properties.getSizeMapping().get(parcelSize.toUpperCase());
return parcelSize != null ? new ParcelSize(parcelSize) : null;
}
}
which depends on ParcelValidationProperties:
#Configuration
#Data
#ConfigurationProperties(prefix = "parcel.validation")
public class ParcelValidationProperties {
private Map<String, String> sizeMapping;
}
Those properties are set in application.yml file and they look like:
parcel:
validation:
size-mapping:
A: A
D: A
E: A
H: A
B: B
F: B
I: B
C: C
G: C
J: C
My test:
#ExtendWith(SpringExtension.class)
#EnableConfigurationProperties(value = ParcelValidationProperties.class)
#TestPropertySource("classpath:application.yml")
class DefaultParcelSizeMapperTest {
#Autowired
private ParcelValidationProperties parcelValidationProperties;
#ParameterizedTest
#MethodSource("provideParcelSize")
void toParcelSize(String size, Object expected) {
var defaultParcelSizeMapper = new DefaultParcelSizeMapper(parcelValidationProperties);
var result = defaultParcelSizeMapper.toParcelSize(size);
Assertions.assertEquals(expected, result.getValue());
}
private static Stream<Arguments> provideParcelSize() {
return Stream.of(
Arguments.of(null, null),
Arguments.of("A", new ParcelSize("A"))
);
}
}
But after test running I got this exception:
java.lang.NullPointerException: Cannot invoke "pl.xyz.qr.qrcodeapi.model.parcel.ParcelSize.getValue()" because "result" is null

What I'm doing wrong and how should I mock property class?
Hy all !
I am working on a spring boot API for my training (I am therefore a beginner) :)
When the program starts, I read a Json file, I map it to my model and I save in the H2 database.
So far i have been doing all of this in the main class with a command line runner.
Everything worked,the rest of the code is also in place, endpoints and unit tests.
Now, i wanted to modify the operation in order to be able to read a different file for the integration tests, using different profile and i do this :
public class SafetyNetAlertsApplication {
public static void main(String[] args) {
SpringApplication.run(SafetyNetAlertsApplication.class, args);
}
#Autowired
JsonDataService jsonDataService;
#Autowired
IDataSourceConfig dataSourceConfig;
#Bean
CommandLineRunner runnerReadJsonWithObjectMapper() {
return args -> {
JsonFileData data = dataSourceConfig.setupData();
SafetyNetAlertInitializer initializer = new SafetyNetAlertInitializer(jsonDataService, data);
initializer.start();
};
}
public interface IDataSourceConfig {
JsonFileData setupData() throws IOException;
}
And implementations, depending on the active profile:
#Component
#Profile("dev")
public class ProdDataSourceConfigImpl implements IDataSourceConfig {
#Override
public JsonFileData setupData() throws IOException {
ObjectMapper objectMapper = new ObjectMapper();
return objectMapper.readValue(new File("src/main/resources/json/data.json"), JsonFileData.class);
}
}
#Component
#Profile("test")
public class TestDataSourceConfigImpl implements IDataSourceConfig {
#Override
public JsonFileData setupData() throws IOException {
ObjectMapper objectMapper = new ObjectMapper();
return objectMapper.readValue(new File("src/test/resources/dataTest.json"), JsonFileData.class);
}
}
I save in h2 database:
public class SafetyNetAlertInitializer {
JsonDataService jsonDataService;
JsonFileData data;
public SafetyNetAlertInitializer(JsonDataService jsonDataService, JsonFileData data) {
this.jsonDataService = jsonDataService;
this.data = data;
}
public void start() {
jsonDataService.savePersons(data.getPersons());
jsonDataService.saveFireStations(data.getFirestations());
jsonDataService.saveMedicalRecords(data.getMedicalrecords());
}
}
The program works, the integration tests too, but no longer the unit tests !
I get an error like: Failed to load ApplicationContext
Caused by: java.lang.NullPointerException
But I can not solve the problem, it is not for lack of having gone through many subjects on this forum, something escapes me ...
This is the error:

And this is one of my UnitTest class:
#ActiveProfiles("test")

#MockBean
private JsonDataService jsonDataService;

public void testGetListOfHomesServedByThisStationsAndResponseIsOk() throws Exception {
Can you help me please ?
I trying to mock a repository but the mockito throw NPE when I will setup the mock.
#DisplayName("Tests for User Logic")
public class UserLogicTest {
#InjectMocks
private UserLogic userLogic;
#Mock
private UserRepository repository;
#Before
public void openMocks() {
MockitoAnnotations.openMocks(this);
}
#BeforeEach
public void setUpMocks() {
Mockito
.when(repository.findById(ArgumentMatchers.any(UUID.class)))
.thenReturn(Optional.of(new UserModel(UUID.randomUUID(), "Nice")));
}
#Test
#DisplayName("Should return null if user does not exist")
public void getUserById() {
var user = userLogic.getOne(UUID.randomUUID());
Assertions.assertNull(user);
}
}
I see a lot of people with the same problem and the solution all for junit 4 or less (even using this solutions with junit vintage I have the same trouble, and I want to use only junit 5 features).
EDIT: stacktrace:
java.lang.NullPointerException

Can anyone help me? Thanks!
If you use the #Mock and #InjectMocks annotations, you need to tell Mockito to initialize those mocks, either by adding
#ExtendWith(MockitoExtension.class)
on your test class or adding the method call
MockitoAnnotations.openMocks(this)
in the #BeforeEach method.
