I try to run a testclass with the JUnit Platform Launcher. The Testclass contains some #Autowired Components. The issue is, that the injection doesn't seem to work. Is that even possible with JUnit Platform?
My code is as follows:
App.java
#SpringBootApplication(scanBasePackages = "com.mytests")
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
Component
import org.springframework.stereotype.Component;
#Component
public class SomeBean {
public String returnSuccess() {
return "SUCCESS";
}
}
Testclass
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
#RunWith(SpringRunner.class)
#SpringBootTest
public class SomeTests {
#Autowired
private SomeBean aBean;
#Test
public void testSuccess() throws Exception {
String result = aBean.returnSuccess();
assertTrue(result.equals("SUCCESS"));
}
}
Controller which calls the test class
#RestController
public class TestController {
#RequestMapping("/tests")
public void executeTests() throws Throwable {
LauncherDiscoveryRequest request = LauncherDiscoveryRequestBuilder.request()
.selectors(selectPackage("com.mytests"), selectClass(SomeTests.class))
.build();
Launcher launcher = LauncherFactory.create();
SummaryGeneratingListener listener = new SummaryGeneratingListener();
launcher.registerTestExecutionListeners(listener);
launcher.execute(request);
listener.getSummary();
}
}

If I have the annotation #WithMockUser on a test class in spring boot, how can I overwrite/null this setting for a single test in which I want to see how the code behaves without set principal?
If you want to see how the code behaves with a different user, you can just put another #WithMockUser directly on the method.
#SpringBootTest
#WithMockUser(username="user", password="password")
public class UserSecurityTest {
#Test
#WithMockUser(username="otherUser", password="password")
public void testMockUserOverride() {
...
}
}
If you want to see how the code behaves with no credentials then you need to clear out the security context at the beginning of your test.
#SpringBootTest
#WithMockUser(username="user", password="password")
public class UserSecurityTest {
#Test
public void testNoAuth() {
SecurityContextHolder.clearContext();
...
}
}
Here is a complete example that includes a test that runs after clearing out the authentication to be sure it is restored to what the class-level mock is set to.
import org.junit.jupiter.api.MethodOrderer;
import org.junit.jupiter.api.Order;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.TestMethodOrder;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContext;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.test.context.support.WithMockUser;
import java.util.Optional;
import static org.junit.jupiter.api.Assertions.assertEquals;
#SpringBootTest
#WithMockUser(username = "user", password = "password")
#TestMethodOrder(MethodOrderer.class)
public class SecurityTest {
public String getCurrentUser() {
return Optional.ofNullable(SecurityContextHolder.getContext())
.map(SecurityContext::getAuthentication)
.map(Authentication::getPrincipal)
.map(user -> ((User)user).getUsername())
.orElse("noAuth");
}
#Test
#Order(0)
public void testClassLevelMockUser() {
assertEquals("user",getCurrentUser());
}
#Test
#Order(1)
#WithMockUser(username = "otherUser")
public void testOverrideMock() {
assertEquals("otherUser", getCurrentUser());
}
#Test
#Order(2)
public void testNoAuth() {
SecurityContextHolder.clearContext();
assertEquals("noAuth", getCurrentUser());
}
#Test
#Order(3)
public void testClassLevelMockUserNotDestroyedByOtherTest() {
assertEquals("user", getCurrentUser());
}
}
The issue is that Application Event is not being captured in Spring boot test While it works fine for files listening to event in app project.
I want to capture an ApplicationEvent in Spring boot test(don't want to do Unit testing). My goal is to capture this application event and then perform few tasks in my test to verify the end-to-end functionality. Since, the event is not being captured in test case so I am not able to write integration tests.
Please let me know what is wrong with the code.
Thanks All.

One way could be to create a very simple listener with #TestComponent inside your test and autowire it as a #MockBean.
Proof of concept (tested with Spring Boot 2.2 and 2.1):
#SpringBootTest
public class PublishTest {
#Autowired
private ApplicationEventPublisher applicationEventPublisher;
#MockBean
private Consumer consumer;
#Test
public void test() {
applicationEventPublisher.publishEvent(new TestEvent(this));
// events are synchronous by default
verify(consumer).consumeEvent(any(TestEvent.class));
}
#TestComponent
private static class Consumer {
#EventListener
public void consumeEvent(TestEvent testEvent) {
}
}
private static class TestEvent extends ApplicationEvent {
public TestEvent(Object source) {
super(source);
}
}
}
I want to do a self-cleaning test
In my situation, I have one of the components depend on a directory
public class FileRepositoryManagerImpl implements ....
#Value("${acme.fileRepository.basePath}")
private File basePath;
}
The value is defined in the application.yml file, and in DEV it points to a directory under build.
This is not the worst idea, because gradle clean will eventually clean up the mess the tests create.
But, really, what I would like to achieve here, is to make sure that every test runs in an isolated temporary directory that is cleaned up after execution.
I know that JUnit has a tool for the temporary directories. But once I have defined that directory in the scope of JUnit 4, how do I tell Spring to use that temporary directory?
I tried the inner class unsuccessfully:
#RunWith(SpringRunner.class)
#SpringBootTest(classes = { SecurityBeanOverrideConfiguration.class, App.class })
#EnableConfigurationProperties
public abstract class AbstractFileRepositoryManagerIntTests {
private final static TemporaryFolder temporaryFolder = new TemporaryFolder();
#ClassRule
public static TemporaryFolder getTemporaryFolder()
{
return temporaryFolder;
}
#ConfigurationProperties(prefix = "acme")
static class Configuration
{
public FileRepository getFileRepository()
{
return new FileRepository();
}
static class FileRepository
{
public File basePath() throws Exception
{
return temporaryFolder.newFolder("fileRepositoryBaseDir");
}
}
}
}
I was thinking about tinkering with the Environment, but what should be the correct way to inject properties programmatically in a Spring Boot test?
I can think of at least four different approaches to your problem. All with their own advantages and disadvantages.
Approach 1: ReflectionTestUtils
You are using #Value annotation on a private instance property (please, don't to that anymore!). Hence, you can not change acme.fileRepository.basePath on the fly without reflection.
package demo;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Component;
import java.io.File;
#SpringBootApplication
public class FileRepositoryApp {
public static void main(String[] args) {
SpringApplication.run(FileRepositoryApp.class, args);
}
#Component
public class FileRepository {
#Value("${acme.fileRepository.basePath}")
private File basePath;
public File getBasePath() {
return basePath;
}
}
}
Changing basePath after each test with ReflectionTestUtils.setField. Because we are using Spring's TestExecutionListener, that gets initialized before Junit rules are initialized, we are forced to manage the temporary folder in beforeTestExecution and afterTestMethod.
package demo;
import org.junit.Test;
import org.junit.rules.TemporaryFolder;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.TestContext;
import org.springframework.test.context.TestExecutionListener;
import org.springframework.test.context.TestExecutionListeners;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.util.ReflectionTestUtils;
import java.io.IOException;
import static junit.framework.TestCase.assertEquals;
import static org.springframework.test.context.TestExecutionListeners.MergeMode.MERGE_WITH_DEFAULTS;
#RunWith(SpringRunner.class)
#SpringBootTest(classes = FileRepositoryApp.class)
#TestExecutionListeners(listeners = FileRepositoryAppTest.SetBasePath.class, mergeMode = MERGE_WITH_DEFAULTS)
public class FileRepositoryAppTest {
private static TemporaryFolder temporaryFolder = new TemporaryFolder();
#Autowired
private FileRepositoryApp.FileRepository fileRepository;
#Test
public void method() {
System.out.println(temporaryFolder.getRoot().getAbsolutePath());
System.out.println(fileRepository.getBasePath());
assertEquals(temporaryFolder.getRoot(), fileRepository.getBasePath());
}
#Test
public void method1() {
System.out.println(temporaryFolder.getRoot().getAbsolutePath());
System.out.println(fileRepository.getBasePath());
assertEquals(temporaryFolder.getRoot(), fileRepository.getBasePath());
}
static class SetBasePath implements TestExecutionListener {
#Override
public void beforeTestExecution(TestContext testContext) throws IOException {
temporaryFolder.create();
if (testContext.hasApplicationContext()) {
FileRepositoryApp.FileRepository bean = testContext.getApplicationContext().getBean(FileRepositoryApp.FileRepository.class);
ReflectionTestUtils.setField(bean, "basePath", temporaryFolder.getRoot());
}
}
#Override
public void afterTestMethod(TestContext testContext) {
temporaryFolder.delete();
}
}
}
Approach 2: Configuration properties
Introduce a configuration properties class for your application configuration. It gives you type safety for free and we don't rely on reflection anymore.
package demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import java.io.File;
#SpringBootApplication
public class FileRepositoryWithPropertiesApp {
public static void main(String[] args) {
SpringApplication.run(FileRepositoryWithPropertiesApp.class, args);
}
#Component
public class FileRepository {
private final FileRepositoryProperties fileRepositoryProperties;
public FileRepository(FileRepositoryProperties fileRepositoryProperties) {
this.fileRepositoryProperties = fileRepositoryProperties;
}
public File getBasePath() {
return fileRepositoryProperties.getBasePath();
}
}
#Component
#ConfigurationProperties(prefix = "acme.file-repository")
public class FileRepositoryProperties {
private File basePath;
public File getBasePath() {
return basePath;
}
public void setBasePath(File basePath) {
this.basePath = basePath;
}
}
}
Because we are using Spring's TestExecutionListener, that gets initialized before Junit rules are initialized, we are forced to manage the temporary folder in beforeTestExecution and afterTestMethod.
package demo;
import org.junit.Test;
import org.junit.rules.TemporaryFolder;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.TestContext;
import org.springframework.test.context.TestExecutionListener;
import org.springframework.test.context.TestExecutionListeners;
import org.springframework.test.context.junit4.SpringRunner;
import java.io.IOException;
import static junit.framework.TestCase.assertEquals;
import static org.springframework.test.context.TestExecutionListeners.MergeMode.MERGE_WITH_DEFAULTS;
#RunWith(SpringRunner.class)
#SpringBootTest(classes = FileRepositoryWithPropertiesApp.class)
#TestExecutionListeners(listeners = FileRepositoryWithPropertiesTest.SetBasePath.class, mergeMode = MERGE_WITH_DEFAULTS)
public class FileRepositoryWithPropertiesTest {
private static TemporaryFolder temporaryFolder = new TemporaryFolder();
#Autowired
private FileRepositoryWithPropertiesApp.FileRepository bean;
#Test
public void method() {
System.out.println(temporaryFolder.getRoot().getAbsolutePath());
System.out.println(bean.getBasePath());
assertEquals(temporaryFolder.getRoot(), bean.getBasePath());
}
#Test
public void method1() {
System.out.println(temporaryFolder.getRoot().getAbsolutePath());
System.out.println(bean.getBasePath());
assertEquals(temporaryFolder.getRoot(), bean.getBasePath());
}
static class SetBasePath implements TestExecutionListener {
#Override
public void beforeTestExecution(TestContext testContext) throws IOException {
temporaryFolder.create();
if (testContext.hasApplicationContext()) {
FileRepositoryWithPropertiesApp.FileRepositoryProperties bean = testContext.getApplicationContext().getBean(FileRepositoryWithPropertiesApp.FileRepositoryProperties.class);
bean.setBasePath(temporaryFolder.getRoot());
}
}
#Override
public void afterTestMethod(TestContext testContext) {
temporaryFolder.delete();
}
}
}
Approach 3: Refactor your code (my favorite)
Extract basePath into its own class and hide it behind an api. Now you don't need to poke with your application properties and a temporary folder anymore.
package demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import java.io.File;
#SpringBootApplication
public class FileRepositoryWithAbstractionApp {
public static void main(String[] args) {
SpringApplication.run(FileRepositoryWithAbstractionApp.class, args);
}
#Component
public class FileRepository {
private final FileRepositorySource fileRepositorySource;
public FileRepository(FileRepositorySource fileRepositorySource) {
this.fileRepositorySource = fileRepositorySource;
}
public File getBasePath() {
return fileRepositorySource.getBasePath();
}
}
#Component
public class FileRepositorySource {
private final FileRepositoryProperties fileRepositoryProperties;
public FileRepositorySource(FileRepositoryProperties fileRepositoryProperties) {
this.fileRepositoryProperties = fileRepositoryProperties;
}
// TODO for the sake of brevity no real api here
public File getBasePath() {
return fileRepositoryProperties.getBasePath();
}
}
#Component
#ConfigurationProperties(prefix = "acme.file-repository")
public class FileRepositoryProperties {
private File basePath;
public File getBasePath() {
return basePath;
}
public void setBasePath(File basePath) {
this.basePath = basePath;
}
}
}
We don't need any additional testing facility anymore and we can use #Rule on TemporaryFolder instead.
package demo;
import org.junit.Before;
import org.junit.Rule;
import org.junit.Test;
import org.junit.rules.TemporaryFolder;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.test.context.junit4.SpringRunner;
import static junit.framework.TestCase.assertEquals;
import static org.mockito.Mockito.when;
#RunWith(SpringRunner.class)
#SpringBootTest(classes = FileRepositoryWithAbstractionApp.class)
public class FileRepositoryWithAbstractionTest {
#Rule
public TemporaryFolder temporaryFolder = new TemporaryFolder();
#MockBean
private FileRepositoryWithAbstractionApp.FileRepositorySource fileRepositorySource;
#Autowired
private FileRepositoryWithAbstractionApp.FileRepository bean;
#Before
public void setUp() {
when(fileRepositorySource.getBasePath()).thenReturn(temporaryFolder.getRoot());
}
#Test
public void method() {
System.out.println(temporaryFolder.getRoot().getAbsolutePath());
System.out.println(bean.getBasePath());
assertEquals(temporaryFolder.getRoot(), bean.getBasePath());
}
#Test
public void method1() {
System.out.println(temporaryFolder.getRoot().getAbsolutePath());
System.out.println(bean.getBasePath());
assertEquals(temporaryFolder.getRoot(), bean.getBasePath());
}
}
Approach 4: TestPropertySource
Use Spring's TestPropertySource annotation to override properties in a test selectively. Because a Java anntotation can not have a dynamic value, you need to decide beforehand where you want to create your directory and keep in mind your test is bound to a specific operating system due to the used os path separator.
package demo;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.TestPropertySource;
import org.springframework.test.context.junit4.SpringRunner;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import static demo.FileRepositoryTestPropertySourceTest.BASE_PATH;
#RunWith(SpringRunner.class)
#SpringBootTest(classes = FileRepositoryApp.class)
#TestPropertySource(properties = "acme.fileRepository.basePath=" + BASE_PATH)
public class FileRepositoryTestPropertySourceTest {
static final String BASE_PATH = "/tmp/junit-base-path";
private Path basePath = Paths.get(BASE_PATH);;
#Autowired
private FileRepositoryApp.FileRepository fileRepository;
#Before
public void setUp() throws IOException {
Files.deleteIfExists(basePath);
Files.createDirectories(basePath);
}
#After
public void after() throws IOException {
Files.deleteIfExists(basePath);
}
#Test
public void method() {
System.out.println(fileRepository.getBasePath());
}
}
If you use JUnit 5.4+ then you can leverage their #TempDir that works just fine without manual lifecycle management of the directory. That is you don't need to create and delete it manually, in contrast to #TemporaryFolder from JUnit 4.
Here is a working example of how you can achieve your goal:
//Your bean into which you want to inject the property
#Component
public class FileRepositoryManager {
#Value("${acme.fileRepository.basePath}")
private File basePath;
public File getBasePath() {
return basePath;
}
}
//Test that uses ApplicationContextInitializer machinery to set the desired properties
#SpringBootTest
#ContextConfiguration(initializers = Initializer.class)
class FileRepositoryManagerTest {
#TempDir
static File tempDir;
#Autowired
FileRepositoryManager fileRepositoryManager;
#Test
void basePathIsSet() {
assertNotNull(fileRepositoryManager.getBasePath());
}
static class Initializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
#Override
public void initialize(ConfigurableApplicationContext context) {
TestPropertyValues.of(
"acme.fileRepository.basePath=" + tempDir
).applyTo(context);
}
}
}

}
When i post the above request i am getting 404 error. Kindly help on this please
I tried your example and you need to add two changes.
In your "main" class, the 'component scan' annotation is right, but you have to add a 'ServletRegistrationBean' with name 'CamelServlet':
package org.funcode.app.main;
import org.apache.camel.component.servlet.CamelHttpTransportServlet;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
#SpringBootApplication(scanBasePackages = {"org.funcode.app"})
public class BatchFileApplication {
private static final String CAMEL_URL_MAPPING = "/api/*";
private static final String CAMEL_SERVLET_NAME = "CamelServlet";
public static void main(String[] args) {
SpringApplication.run(BatchFileApplication.class, args);
}
#Bean
public ServletRegistrationBean servletRegistrationBean() {
ServletRegistrationBean registration =
new ServletRegistrationBean(new CamelHttpTransportServlet(), CAMEL_URL_MAPPING);
registration.setName(CAMEL_SERVLET_NAME);
return registration;
}
}
And if you want view on the log the content you posted on the request, you need to change the method of the request to "post":
package org.funcode.app.main;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.model.rest.RestBindingMode;
import org.springframework.stereotype.Component;
#Component
public class BatchFileService extends RouteBuilder {
#Override
public void configure() throws Exception {
restConfiguration().component("servlet").bindingMode(RestBindingMode.json);
rest("/batchFile")
.consumes("application/json")
.produces("application/json")
.post("/routeStart")
.to("direct:startRoute");
}
}
I hope it helps.
I have a parent class Car & a sub class Axio. So, i'm trying to pass an argument through super("Axio") within child constructor to constructor parameter in the parent class which then assign the value into a property defined within the parent class. When i try executing the application in spring boot it throws me an exception stating
Description:
Field car in com.test.efshop.controller.HelloController required a bean of type 'com.test.efshop.Axio' that could not be found.
Action:
Consider defining a bean of type 'com.test.efshop.Axio' in your configuration.
Can anyone please tell me how to achieve this in spring boot?. My Code is as below,
// Car class
package com.test.efshop;
public class Car {
private String carName;
public String getCarName() {
return carName;
}
public void setCarName(String carName) {
this.carName = carName;
}
public Car(String carName) {
this.carName = carName;
}
public String print() {
return "Car name is : "+carName;
}
}
//sub class of car class which is Axio
package com.test.efshop;
public class Axio extends Car{
public Axio() {
super("Axio");
}
}
//main method
package com.test.efshop;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;
#SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
//controller class
package com.test.efshop.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
import com.test.efshop.Axio;
import com.test.efshop.Engine;
#Controller
public class HelloController {
#Autowired
private Axio car;
#RequestMapping(value = "/hello")
public ModelAndView print() {
return new ModelAndView("index");
}
//This is the method which i used to return the value of Car class
#RequestMapping(value = "/hello2")
#ResponseBody
public String print2() {
return car.print();
}
}
As pvpkiran commented, you can't #Autowire a class if it's not a Spring bean.
Option a) you convert the Axio class into a service or component.
#Component
public class Axio extends Car {
public Axio() {
super("Axio");
}
}
Option b) you define a bean of type Axio.
#SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
#Bean
public Axio myAxioBean() {
return new Axio();
}
}
