I tried to implement a junit test with the usage of Point in Spring Boot. I completed junit test but I have a problem to handle with Point issue in generateValidUserEntities method of AssignmentEntityBuilder.
How can I fix it?
Here is the AssignmentEntity shown below
...
public class AssignmentEntity extends BaseEntity {
...
public void setPoint(double latitude, double longitude) {
Coordinate coordinate = new Coordinate(latitude, longitude);
GeometryFactory geometryFactory = new GeometryFactory();
this.point = geometryFactory.createPoint(coordinate);
}
}
Here is the AssignmentEntityBuilder shown below
public class AssignmentEntityBuilder extends TestDataBuilder<AssignmentEntity> {
public AssignmentEntityBuilder() {
super(AssignmentEntity.class);
}
public static List<AssignmentEntity> generateValidUserEntities(int size) {
List<AssignmentEntity> userEntities = new ArrayList<>();
for (int i = 0; i < size; i++) {
AssignmentEntity assignmentEntity = new AssignmentEntityBuilder().withValidFields().build();
userEntities.add(assignmentEntity);
}
return userEntities;
}
public AssignmentEntityBuilder withValidFields() {
InstitutionEntity institutionEntity = new InstitutionEntityBuilder().withValidFields().build();
double x = Math.random();
double y = Math.random();
Point point = new GeometryFactory().createPoint(new Coordinate(x, y));
return this
.withId(AysRandomUtil.generateUUID())
.withInstitutionId(institutionEntity.getId())
.withInstitution(institutionEntity)
.withPhoneNumber(new AysPhoneNumberBuilder().withValidFields().build())
.withDescription("Description")
.withFirstName("First Name")
.withLastName("Last Name")
.withStatus(AssignmentStatus.AVAILABLE)
.withPoint(point);
}
public AssignmentEntityBuilder withId(String id) {
data.setId(id);
return this;
}
public AssignmentEntityBuilder withInstitutionId(String institutionId) {
data.setInstitutionId(institutionId);
return this;
}
public AssignmentEntityBuilder withPhoneNumber(AysPhoneNumber phoneNumber) {
data.setCountryCode(phoneNumber.getCountryCode());
data.setLineNumber(phoneNumber.getLineNumber());
return this;
}
public AssignmentEntityBuilder withInstitution(InstitutionEntity institution) {
data.setInstitution(institution);
return this;
}
public AssignmentEntityBuilder withDescription(String description) {
data.setDescription(description);
return this;
}
public AssignmentEntityBuilder withFirstName(String firstName) {
data.setFirstName(firstName);
return this;
}
public AssignmentEntityBuilder withLastName(String lastName) {
data.setLastName(lastName);
return this;
}
public AssignmentEntityBuilder withStatus(AssignmentStatus status) {
data.setStatus(status);
return this;
}
public AssignmentEntityBuilder withPoint(Point point) {
data.setPoint(point);
return this;
}
}
Here is the service class shown below
class AssignmentSaveServiceImplTest extends AbstractUnitTest {
@InjectMocks
private AssignmentSaveServiceImpl assignmentSaveService;
@Mock
private AssignmentRepository assignmentRepository;
@Mock
private AysIdentity identity;
@Test
void givenValidAssignmentSaveRequest_whenAssignmentSaved_thenReturnAssignment() {
// Given
AssignmentSaveRequest mockAssignmentSaveRequest = new AssignmentSaveRequestBuilder()
.withValidFields()
.build();
List<AssignmentEntity> assignmentsFromDatabase = AssignmentEntityBuilder.generateValidUserEntities(10); --- ERROR LINE
AssignmentEntity mockAssignmentEntity = new AssignmentEntityBuilder()
.withValidFields().build();
// When
Mockito.when(assignmentRepository.findAll())
.thenReturn(assignmentsFromDatabase);
Mockito.when(assignmentRepository.save(Mockito.any(AssignmentEntity.class)))
.thenReturn(mockAssignmentEntity);
Mockito.when(identity.getInstitutionId())
.thenReturn(AysRandomUtil.generateUUID());
// Then
Assignment assignment = assignmentSaveService.saveAssignment(mockAssignmentSaveRequest);
Assertions.assertEquals(mockAssignmentSaveRequest.getFirstName(), assignment.getFirstName());
Assertions.assertEquals(mockAssignmentSaveRequest.getLastName(), assignment.getLastName());
Assertions.assertEquals(mockAssignmentSaveRequest.getPhoneNumber().getLineNumber(), assignment.getPhoneNumber().getLineNumber());
Assertions.assertEquals(mockAssignmentSaveRequest.getPhoneNumber().getCountryCode(), assignment.getPhoneNumber().getCountryCode());
Assertions.assertEquals(mockAssignmentSaveRequest.getDescription(), assignment.getDescription());
Assertions.assertEquals(mockAssignmentSaveRequest.getDescription(), assignment.getDescription());
Assertions.assertEquals(mockAssignmentSaveRequest.getLongitude(), assignment.getLongitude());
Assertions.assertEquals(mockAssignmentSaveRequest.getLatitude(), assignment.getLatitude());
Mockito.verify(assignmentRepository, Mockito.times(1)).findAll();
Mockito.verify(identity, Mockito.times(1)).getInstitutionId();
}
}

Here is the solution show below
1 - Define a class named PointRandomizer extending from AbstractRandomizer to generate Point randomly.
class PointRandomizer extends AbstractRandomizer<Point> {
@Override
public Point getRandomValue() {
Coordinate[] coordinates = new Coordinate[]{new Coordinate(40.991739, 29.024168)};
CoordinateSequence coordinateSequence = new CoordinateArraySequence(coordinates);
GeometryFactory geometryFactory = new GeometryFactory();
return geometryFactory.createPoint(coordinateSequence);
}
}
2 - Define a static final variable named PointRandomizer
private static final PointRandomizer POINT_RANDOMIZER = new PointRandomizer();
3 - Add POINT_RANDOMIZER to EasyRandomParameters to produce point values randomly
parameters.randomize(Point.class, POINT_RANDOMIZER);
Here is the final TestBuilder class shown below
public abstract class TestDataBuilder<T> {
protected final EasyRandom generator;
protected T data;
protected Class<T> clazz;
private static final PositiveIntegerRandomizer POSITIVE_INTEGER_RANDOMIZER = new PositiveIntegerRandomizer();
private static final LongRangeRandomizer LONG_RANGE_RANDOMIZER = new LongRangeRandomizer(1L, Long.MAX_VALUE);
private static final CharacterRandomizer CHARACTER_RANDOMIZER = new CharacterRandomizer();
private static final PointRandomizer POINT_RANDOMIZER = new PointRandomizer();
public TestDataBuilder(Class<T> clazz) {
this(clazz, false);
}
public TestDataBuilder(Class<T> clazz, boolean excludeRelations) {
this.clazz = clazz;
this.generator = new EasyRandom(this.getExclusionParameters(excludeRelations));
this.data = generator.nextObject(clazz);
}
public T build() {
return data;
}
private EasyRandomParameters getExclusionParameters(boolean excludeRelations) {
EasyRandomParameters parameters = new EasyRandomParameters();
parameters.randomize(Integer.class, POSITIVE_INTEGER_RANDOMIZER);
parameters.randomize(String.class, CHARACTER_RANDOMIZER);
parameters.randomize(Long.class, LONG_RANGE_RANDOMIZER);
parameters.randomize(Point.class, POINT_RANDOMIZER);
if (!excludeRelations) return parameters;
parameters.excludeField(
FieldPredicates.isAnnotatedWith(ManyToOne.class, OneToMany.class, OneToOne.class)
.or(named("id"))
);
return parameters;
}
}
class PositiveIntegerRandomizer extends IntegerRangeRandomizer {
private static final int MIN = 0;
private static final int MAX = 100;
public PositiveIntegerRandomizer() {
super(MIN, MAX);
}
@Override
protected Integer getDefaultMinValue() {
return MIN;
}
}
class CharacterRandomizer extends StringRandomizer {
@Override
public String getRandomValue() {
return RandomStringUtils.randomAlphabetic(10);
}
}
class PointRandomizer extends AbstractRandomizer<Point> {
@Override
public Point getRandomValue() {
Coordinate[] coordinates = new Coordinate[]{new Coordinate(40.991739, 29.024168)};
CoordinateSequence coordinateSequence = new CoordinateArraySequence(coordinates);
GeometryFactory geometryFactory = new GeometryFactory();
return geometryFactory.createPoint(coordinateSequence);
}
}
