Hi I have wrote test class like this:
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.HttpMethod;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.test.web.client.ExpectedCount;
import org.springframework.test.web.client.MockRestServiceServer;
import org.springframework.web.client.RestTemplate;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import static org.assertj.core.api.Assertions.assertThatCode;
import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.springframework.test.web.client.match.MockRestRequestMatchers.method;
import static org.springframework.test.web.client.match.MockRestRequestMatchers.requestTo;
import static org.springframework.test.web.client.response.MockRestResponseCreators.withStatus;
#SpringBootTest
public class udsfhgdsfg {
private RestTemplate restTemplate = new RestTemplate();
private MockRestServiceServer mockServer;
#BeforeEach
public void init() {
mockServer = MockRestServiceServer.createServer(restTemplate);
}
#Test
void assert_that_service_create_object_with_good_params() throws IOException, InterruptedException, URISyntaxException {
mockServer.expect(ExpectedCount.once(),
requestTo(new URI("http://localhost:8080/example")))
.andExpect(method(HttpMethod.GET))
.andRespond(withStatus(HttpStatus.OK)
.contentType(MediaType.APPLICATION_JSON)
.body("example")
);
HttpClient httpClient = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder()
.GET()
.uri(URI.create("http://localhost:8080/example"))
.build();
HttpResponse<String> httpResponse = httpClient.send(request, HttpResponse.BodyHandlers.ofString());
assertEquals("example", httpResponse.body());
}
}
And I'm getting stacktrace like below:

I want to simulate api connection with mock server with http response for get method. I wrote example method that should always assert true when mock server would works fine. Somebody knows what did I wrong? Thanks for your answers.
your issue is where you call the URL , please find the best way to do that :
#Test
void assert_that_service_create_object_with_good_params() throws IOException, InterruptedException, URISyntaxException {
mockServer.expect(ExpectedCount.once(),
requestTo(new URI("http://localhost:8081/example")))
.andExpect(method(HttpMethod.GET))
.andRespond(withStatus(HttpStatus.OK)
.contentType(MediaType.APPLICATION_JSON)
.body("example")
);
String result = null;
try {
result = restTemplate.getForObject("http://localhost:8081/example",String.class);
System.out.println("addComment: " + result);
} catch (HttpClientErrorException e) {
result = e.getMessage();
}
assertEquals("example", result);
}
That's working fine.

I have a pretty simple Spring repository unit test for my Task entity.
Here is how the repository is configured:
#Repository
interface TaskRepository : CrudRepository<Task, Long>
Here is the logic I'd like to test:
// TaskService.kt
fun deleteSubTask(parentTask: Task, subTask: Task) {
taskRepository.save(parentTask)
parentTask.subTasks?.remove(subTask)
taskRepository.delete(subTask)
}
and here is my unit test (with JUnit5 and Mockk):
//TaskServiceTest.kt
internal class TaskServiceTest {
private val taskRepository: TaskRepository = mockk(relaxed = true)
private val taskService = TaskService(mockk(relaxed = true), taskRepository)
#Test
fun `should remove subtask of parent task`() {
val subTask: Task = mockk()
val parentTask: Task = mockk()
taskService.deleteSubTask(parentTask, subTask)
verify { parentTask.subTasks?.remove(subTask) }
verify { taskRepository.delete(subTask) }
verify { taskRepository.save(parentTask) }
}
}
When executing the test the following error appears:
22:48:51.245 [Test worker] DEBUG io.mockk.impl.instantiation.AbstractMockFactory - Creating mockk for TaskRepository name=#1
22:48:51.483 [Test worker] DEBUG io.mockk.impl.instantiation.AbstractMockFactory - Creating mockk for UserRepository name=#2

I have no idea why taskRepository.delete(subTask) does work and for taskRepository.save(parentTask) the test fails with the posted error?
It seems that the thrown error was cause because I declared the TaskRepository mock as relaxed. When declaring only void functions (those returning Unit in Kotlin) to be relaxed it worked.
Here is the working unit test:
internal class TaskServiceTest {
private val taskRepository: TaskRepository = mockk(relaxUnitFun = true) // changed from relaxed to relaxUnitFun
private val taskService = TaskService(mockk(relaxed = true), taskRepository)
#Test
fun `should remove subtask of parent task`() {
val subTask: Task = mockk()
val parentTask: Task = mockk() {
every { subTasks } returns mutableListOf(subTask)
}
every { taskRepository.save(any()) } returns mockk()
taskService.deleteSubTask(parentTask, subTask)
verify { parentTask.subTasks?.remove(subTask) }
verify { taskRepository.delete(subTask) }
verify { taskRepository.save(parentTask) }
}
}
I am fairly new to test-driven web application development. I built a sample photo upload application to understand the fundamentals. POST and GET requests APIs can easily be tested with postman without any error. In the POST request, I send an image file and the title for that image. It's content-type is Multipart/form-data. I wanted to write the test for the same POST method using MockMVC. I followed the short tutorial on testing multipart post requests 1. However, I get a null pointer exception and I am not sure if it is the proper way to test a post request API. Can't I post a file and title:'test-title' at the same time as a parameter? I want to know the best practice of testing such an API. I would be very happy. If anyone can help.
Service class:
#Service
public class PhotoService {
#Autowired
private PhotoRepository photoRepo;
public Photo addPhoto(String title, MultipartFile file) throws IOException{
Photo photo = new Photo(title);
photo.setImage(new Binary(BsonBinarySubType.BINARY, file.getBytes()));
return photoRepo.insert(photo);
}
public Photo getPhoto(String id ){
return photoRepo.findById(id).get();
}
}
Controller class:
#RestController
public class PhotoController {
#Autowired
private PhotoService photoService;
#Autowired
private PhotoRepository photoRepo;
#PostMapping("/photos/add")
public String addPhoto(#RequestParam("title") String title, #RequestParam("image") MultipartFile image)
throws IOException{
System.out.print(title);
String id = photoService.addPhoto(title, image).getId();
return "redirect:/photos/" + id;

ps: This is an experimental application development I would be happy to focus on how to test rather than its usage and functionality.
Thank you.
Looks like photoService.addPhoto(title, image) returning null. Because you haven't expected that to return something.
As there is a call to photoService method and photoService is mocked one, you need to pass the mocked value to it as below:
when(photoService.addPhoto(anyString(), anyObject()).thenReturn(${yourObject});
And this should be before API call.
I've created a very basic Spring boot project and I want to perform a simple query to MongoDB (v 4.4.4):
#SpringBootTest
class DemoApplicationTests {
#Autowired
MongoOperations operations;
#Test
void sliceSimple() {
final Criteria criteria = Criteria.where("_id").is(new ObjectId("5a3931f6d60180000f16db8c"));
Query query = Query.query(criteria);
query.fields().slice("subcategories", 0, 1);
operations.find(query, Category.class);
}
}
public class Category {
public List<String> subcategories;
}
But it results with an exception:
Can't find a codec for class [Ljava.lang.Integer;.

Looking at the slice(String, int, int) definition, there is a usage of Integer[]:
/**
* Project a {#code $slice} of the array {#code field} using the first {#code size} elements starting at
* {#code offset}.
*
* #param field the document field name to project, must be an array field.
* #param offset the offset to start at.
* #param size the number of elements to include.
* #return {#code this} field projection instance.
*/
public Field slice(String field, int offset, int size) {
slices.put(field, new Integer[] { offset, size });
return this;
}
Do somebody know if what is happening? Am I missing something in my configuration?
My build.gradle:
plugins {
id 'org.springframework.boot' version '2.5.4'
id 'io.spring.dependency-management' version '1.0.11.RELEASE'
id 'java'
}
group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'
repositories {
mavenCentral()
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-data-mongodb'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
}
test {
useJUnitPlatform()
}
Ps. I was also trying to use custom converter for Integer array:
public class JavaIntegerArrayToListConverter implements Converter<Integer[], List<Integer>> {
#Override
public List<Integer> convert(final Integer[] source) {
return source == null ? null : Arrays.asList(source);
}
}
and register with:
#Primary
#Bean
public MongoTemplate mongoTemplate(MongoDatabaseFactory mongoDbFactory,
MappingMongoConverter mappingMongoConverter) {
mappingMongoConverter.setCustomConversions(new MongoCustomConversions(
Collections.singletonList(new JavaIntegerArrayToListConverter())));
mappingMongoConverter.afterPropertiesSet();
return new MongoTemplate(mongoDbFactory, mappingMongoConverter);
}
But without any effect.
Thanks in advance for any help.
Seems like a bug in mongo library.
This workaround solves problem for me - just do the same thing as slice method does, but with List instead of Array:
((Map<String, Object>) FieldUtils.getFieldValue(query.fields(), "slices"))
.put("subcategories", List.of(0, 1));
FieldUtils from apache commons-lang3

This question already has answers here:
Mockito : how to verify method was called on an object created within a method?
(8 answers)
Closed 2 years ago.
I tried to test the following method sendMail
public void sendMail(Student student, String currentSubject, File file) {
String emailText = createCustomizedEmailBodyText(student, currentSubject);
String mail = student.getEmail();
String subject = "Ihr Zulassungsnachweis zum Fach: ";
sendMessage(mail, subject + currentSubject, emailText, file, file.getName());
file.deleteOnExit();
}
My test class so on
package mops.zulassung2.services;
import mops.zulassung2.model.dataobjects.Student;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.Test;
import org.mockito.Mockito;
import org.springframework.mail.javamail.JavaMailSender;
import java.io.File;
import static org.mockito.Mockito.mock;
class EmailServiceTest {
static EmailService emailServices = mock(EmailService.class);
static EmailService emailService;
static SignatureService signatureService = mock(SignatureService.class);
#BeforeAll
static void setUp() {
JavaMailSender javaMailSender = mock(JavaMailSender.class);
emailService = new EmailService(javaMailSender, signatureService);
}
#Test
void sendMail() {
Student student = new Student("272490", "snami100#uni-duesseldorf.de", "Amin", "Snur");
String subject = "Informatik";
File file = mock(File.class);
Mockito.verify(emailServices).sendMail(student, subject, file);
}
}
In this test i just want to know if the method sendMail is called (with the params)
Im new at programming and maybe someone could help me
This is the error i got when i try to run the test, i dont know what it mean, so maybe someone could help me to make the the test running and sucess, thanks....
Wanted but not invoked:
emailService.sendMail(
mops.zulassung2.model.dataobjects.Student#327fca0d,
"Informatik",
Mock for File, hashCode: 1035729309
);
-> at mops.zulassung2.services.EmailServiceTest.sendMail(EmailServiceTest.java:31)
Actually, there were zero interactions with this mock.

Tests should follow the structure Given-When-Then (GWT).
In your code you have then Given and the Then but the When (emailServices.sendMail() call) is missing:
#Test
void sendMail() {
// Given
Student student = new Student("272490", "snami100#uni-duesseldorf.de", "Amin", "Snur");
String subject = "Informatik";
File file = mock(File.class);
// When
emailServices.sendMail(student, subject, file);
// Then
Mockito.verify(emailServices, times(1)).sendMail(student, subject, file);
Mockito.verify(emailServices, times(1)).sendMessage(anyString(), anyString(), anyString(), anyObject(), anyString());
}
It's a bit hard to be sure because I don't know what class the sendMail method is in.
Also, you might get yourself in trouble with setting up all your mocked variables in as class-wide variables with the use of static and #BeforeAll instead of #BeforeEach.
The basic problem with your test is that you aren't calling the method you are trying to test.
I think you are trying to do something like this:
#Test
void sendMail() {
// Given
Student student = new Student("272490", "snami100#uni-duesseldorf.de", "Amin", "Snur");
String subject = "Informatik";
File file = mock(File.class);
// When
emailServices.sendMail(student, subject, file);
// Then
Mockito.verify(something).sendMessage(eq(student), eq(subject), eq(file));
Mockito.verify(file).deleteOnExit();
}
As #jeprubio said, it will help to organize your tests in the Given-When-Then format so you are more clear on what you are assuming about your test and what you are testing.
