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
at pl.xyz.qr.qrcodeapi.mapper.DefaultParcelSizeMapperTest.toParcelSize(DefaultParcelSizeMapperTest.java:32)

What I'm doing wrong and how should I mock property class?

I'm using Mockito and jUnit5 to test my service, but I'm getting an exception error when testing the update method. The error points to the line below in my CategoryService but I don't know why. How can i test my update method correctly?
.orElseThrow(() -> new MyException(ErrorTable.CATEGORY_NOT_FOUND));
CategoryService
public Category update(Long id, CategoryDto categoryDto) {
Category category = categoryRepository.findById(id)
.orElseThrow(() -> new MyException(ErrorTable.CATEGORY_NOT_FOUND));
mapper.map(categoryDto, category);
return categoryRepository.save(category);
}
CategoryServiceTest
private static final Long ID = 1L;
private static final String NAME = "horror";
#InjectMocks
private CategoryService service;
#Mock
private CategoryRepository repository;
#Mock
private ModelMapper mapper;
#BeforeEach
void setup() {
MockitoAnnotations.openMocks(this);
startCategory();
}
#Test
void whenUpdateCategoryThanReturnSuccess() {
when(repository.save(any())).thenReturn(category);
Category response = service.update(ID, categoryDto);
assertNotNull(response);
assertEquals(Category.class, response.getClass());
assertEquals(ID, response.getId());
assertEquals(NAME, response.getName());
}
private void startCategory() {
category = new Category();
category.setId(ID);
category.setName(NAME);
categoryDto = new CategoryDto();
categoryDto.setName(NAME);
}

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:

Can you help me please ?
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
}
