I would like to test my controller class. But I couldn't manage to run springBootTest class. My project written in spring boot. We are writing REST API using spring boot.
When I try to excute following test class. I still get following line from terminal.
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.boot.test.context.SpringBootTest;
import static org.assertj.core.api.Assertions.assertThat;
/*

#SpringBootTest
#WebMvcTest
public class PrivilegesControllerTest {
#Autowired
private PrivilegesController privilegesController;
#Test
public void add() {
assertThat(privilegesController).isNotNull();
}
}
I put here all needed dependency for testing from my project.

What might be cause of not working of test Class.
With Junit5 and #SpringBootTest will load the full application, I had faced the same issue before, you can find details about the question here and answer here.
The solution for this is to use your test without #SpringBootTest.
The solution to your test class is as below.
#ExtendWith(MockitoExtension.class)
public class PrivilegesControllerTest {
#InjectMocks
private PrivilegesController privilegesController;
#Test
public void add() {
assertThat(privilegesController).isNotNull();
}
}
You can also use #ExtendWith(SpringExtension.class) instead of #ExtendWith(MockitoExtension.class)
To test spring boot application is creating your controller, use #SpringBootTest annotation, and to test the behavior or responsibility of the controller is better to use #WebMvcTest. No need to annotate both the annotation to one class.
There are two cases to test the controller's responsibility.
With running Server
Without Server
For 1st Case, you can use #SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT) to start a server with a random port.
For 2nd Case, use #WebMvcTest for testing the web layer.
All the test cases are written with the following signature:
#Test
public void test_Name() throws Exception {
//your test definition
}
You can also read the Official Documentation of Spring Boot https://spring.io/guides/gs/testing-web/
In summary, Intellij tells me that no MessageMapping and SendTo annotations could be found!?
I included the sprint-boot-starter-websocket like that:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
After i implemented a websocket controller intellij tells me that there are no MessageMapping and SendTo annotations found.
#Controller
public class WebSocketController
{
#MessageMapping("/chat/{topic}")
#SendTo("/topic/messages")
public String send( #DestinationVariable("topic") String topic, Message message){
return "test";
}
}
I also tried to include:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-messaging</artifactId>
<version>5.0.7.RELEASE</version>
</dependency>
but that did not work too.
What do i wrong?
EDIT:
In project structure>modules>dependencies a error message say
Library 'Maven: org.springframework:spring-messaging:5.0.7:RELEASE' has broken path.
What does that mean?
Anybody know why it doesn't work?

What's the problem, why doesn't it find JPA entities when I run WebApplicationAware class?
Spring does not find any JPA Entities, so no JPA Meta Model is created, that is why you face the exception.
The cause of this problem may be a wrong persistence-api version on your class path.
You are using
<dependency>
<groupId>javax.persistence</groupId>
<artifactId>persistence-api</artifactId>
<version>1.0.2</version>
</dependency>
but I am pretty shure your spring version uses persistence-api version 2.
Could it be, you are using #Entity annotation from version 1 ?
At runtime spring uses version 2, and this is searching for Entites using #Entity from version 2 only !
Remove the dependencies
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>1.11.1.RELEASE</version>
</dependency>
Instead add
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
This will give you all JPA dependencies in the right version.
I solved it by adding 2 annotations
#EnableAutoConfiguration
#EntityScan(basePackages = { "com.wt.rds" })
and my dependency was in gradle
compile group: 'org.springframework.boot', name: 'spring-boot-starter-data-jpa', version: '2.0.4.RELEASE'
Unfortunately, most of the springboot guides on JPA integration test often lack a piece of configuration here and there.
So here is an example that hopefully should just work for you.
Point 1.
My local environment is currently setup to use springboot version:
<version.spring.boot>1.5.9.RELEASE</version.spring.boot>
That being said, I am currently setting up my local environment to be able to run integration tests against multiple databases (e.g. postgres, hsql, h2).
Therefore, I start by googling any random toturial that approaches this problem.
The next link is one such example:
https://www.baeldung.com/spring-testing-separate-data-source
The above example is a good starting point. It allows you to scoop up a valid Entity and a Valid repository. The springboot test class itself, on the other hand, leaves a lot ot be desired.
With the above example, you will immediately struggle with the integration test. You will get the usuable problems about the example not giving you the application.class to configure the integration test, and you are left hanging clueless as to what springboot annotations you need to put "where" to make the test to finally run without explosions.
So now I give you a MINIMAL set of 3 classes (Entity + Repository + SpringbootTest) that should hopefully have 100 percent of the configuration you need. This will serve as a basis of any JPA based integration test you will need to do in the future, then you can swap your entities and repositories, and continue testing with the same type of srpingboot configuration.
I start by giving you the IRRELEVANT classes. The stuff that is always the same, the stuff that you want to test, and that has nothing to do with configuration.
I am referring to REPOSITORY + ENTITY.
In eclipse create your java package:
tutorial.www.baeldung.com.tutorial001jpa.separateDS
Dump into this package the following trivial entity and repository classes, that are based on the tutorial reference I gave above.
Tutorial001GenericEntity
package tutorial.www.baeldung.com.tutorial001jpa.separateDS;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name = "TUTORIAL_001_GENERIC_ENTITY")
public class Tutorial001GenericEntity {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String value;
public Tutorial001GenericEntity() {
super();
}
public Tutorial001GenericEntity(String value) {
super();
this.value = value;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
// standard constructors, getters, setters
}
Then we go for the second trivial code snippet.
The spring repository boiler plate code.
Tutorial001GenericEntityRepository
package tutorial.www.baeldung.com.tutorial001jpa.separateDS;
import org.springframework.data.jpa.repository.JpaRepository;
public interface Tutorial001GenericEntityRepository extends JpaRepository<Tutorial001GenericEntity, Long> {
}
At this point your maven project, src/test/java has a total of two classes. The basic stuff.
An entity and a repository, that serve as an example of any integration test you will ever need to do.
So now you go to the only important class in the example, the stuff that always gives a lot of problems, and that is the springboot test class which more then being responsible to test your business logic also has the complex task of CONFIGURING your test.
In this case, this test class has ALL IN ONE the annotations that allow springboot to disocver your entities, repositories, etc...
package tutorial.www.baeldung.com.tutorial001jpa.separateDS;
import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertNotNull;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;
#RunWith(SpringRunner.class)
#ContextConfiguration(classes = {
tutorial.www.baeldung.com.tutorial001jpa.separateDS.Tutorial001GenericEntityIntegrationTest.ConfigureJpa.class })
#SpringBootTest()
public class Tutorial001GenericEntityIntegrationTest {
#EntityScan(basePackageClasses = { Tutorial001GenericEntity.class })
#EnableJpaRepositories(basePackageClasses = Tutorial001GenericEntity.class)
#EnableAutoConfiguration()
public static class ConfigureJpa {
}
#Autowired
private Tutorial001GenericEntityRepository genericEntityRepository;
#Test
public void givenTutorial001GenericEntityRepository_whenSaveAndRetreiveEntity_thenOK() {
Tutorial001GenericEntity genericEntity = genericEntityRepository.save(new Tutorial001GenericEntity("test"));
Tutorial001GenericEntity foundEntity = genericEntityRepository.findOne(genericEntity.getId());
assertNotNull(foundEntity);
assertEquals(genericEntity.getValue(), foundEntity.getValue());
}
}
The important thing, you see, is that this spring boot test has a class level annotation to provide to the springboot test the configuration context.
What we are doing is dumping one and only one class reference that represents our test configuration.
tutorial.www.baeldung.com.tutorial001jpa.separateDS.Tutorial001GenericEntityIntegrationTest.ConfigureJpa.class
And then on this little guy, you put all of the additional annotations in the world you need that springboot offers to configure applications.
In this case we have a dedicated annotation to mention entities.
Another to mention repositories.
And another to tell springboot to activate its auto configuration.
This springboot auto configuration annotation then does additional vodoo, like looking at your classpath and seeing that you have in the classpath say:
<dependency>
<groupId>org.hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<scope>test</scope>
<version>2.3.4</version>
</dependency>
And it will immediately know how to configure an in memory data source for this database.
Behind the scenes, there might be additional configuration that is getting used.
For example, if you create an application.properties file in your src/test/resources that file will be considered.
It is very to see that the appliction.properties is considered by your running test.
If you want to verify this, make sure that in your test setup you do not have, for example, any dependency on the JDBC driver for postgres.
And then put into your application.properties something liek this:
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
This dialect is not compatible with HSQL or H2, so it will immediately make your green passing integration test blow up.
To be honest, I do not know if there is a simpler combo of annotations to properly configure the springboot scanning for an integration test.
As a rule, I would recommend that you try avoiding having hundreds of thousands of configuration classes in your src/test/resources.
Because if at some point you want to toggle all of your integration tests from using applicat-postgres.proeprties to application-hsql.properties, you might find yourself needing to tweak multiple configuration classes instead of just one.
So as rule, per maven component you write, I would try to have the tests that check repositories extend some sort of MyBaseINtegrationTestClass, and in there put this
#ContextConfiguration(classes = {
tutorial.www.baeldung.com.tutorial001jpa.separateDS.Tutorial001GenericEntityIntegrationTest.ConfigureJpa.class })
So that you only need to play with one configuration for testing for the hole project.
IN any case, hopefully the triplet of classes given here helps you.
One finel thing, for maven dependencies for integration testing, here is what I am using:
<!-- Test Dependencies JPA REPOSITORY TESTS -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>

<scope>test</scope>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>test</scope>
</dependency>
The reason why i am using hsql and h2 is beacuse I want my integration tests to be able to be tunned to either use application-hsql or application-h2.properties.
I created a automated test scenario using selenium + cucumber on java, and when I try to execute my test nothing occur.

You need to add glue option to cucumberoptions with the path to the step definition classes. Use glue="com.tdd.facebook". I am not sure about this but you might want to remove the constructor in the runner RunTest.
In the LoginStps class - i_try_to_login_on_facebook() method, you are declaring another driver variable and initializing it. Thus the driver field of the class will remain null. Remove this. Also in the same method you are throwing a k. As you have implemented the step you do not need it anymore.
Also do check if all the jars are imported in the pom. I think you are missing some jars. Check the cucumber java page.
I got the following error message every time I try to call my REST service
[2016-09-01T16:27:37.782+0200] [Payara 4.1] [SEVERE] [] [org.glassfish.jersey.message.internal.WriterInterceptorExecutor] [tid: _ThreadID=28 _ThreadName=http-listener-1(3)] [timeMillis: 1472740057782] [levelValue: 1000] [[MessageBodyWriter not found for media type=application/json, type=class xxx.JsonClass, genericType=class xxx.JsonClass.]]
Here's the REST service (stripped to the relevant part):
import javax.ejb.EJB;
import javax.ws.rs.FormParam;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;
#Path("/service")
public class Service {
#GET
#Path("/callme")
#Produces(MediaType.APPLICATION_JSON)
public JsonClass callme(//
#QueryParam("test") final String test, //
....) {
return new JsonClass();
}
}
The JSON Class
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.annotation.JsonTypeInfo;
public class JsonClass {
private String test;
public JsonClass(final String test....) {
...
}
#JsonProperty
public String getTest() {
return this.test;
}
}
POM.xml (interesting parts)
<!-- DO NOT change the scope for jersey: https://java.net/jira/browse/JERSEY-1941 -->
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-jackson</artifactId>
<version>2.8</version>
<scope>provided</scope>
</dependency>
My setup is:
JDK8/JEE7 (build 1.8.0_51-b16)
Glassfish 4.1 Payara
Maven 3.2.5
This is what I tried so far:
MessageBodyWriter not found for media type=application/json -> Doesn't work because I run into a problem with Glassfish 4 and Weld (https://java.net/jira/browse/JERSEY-1941)
SEVERE: MessageBodyWriter not found for media type=application/json, type=class com.jersey.jaxb.Todo, genericType=class com.jersey.jaxb.Todo -> As seen in the POM.xml above it's already included and does not work
https://java.net/jira/browse/JERSEY-2715 -> Annotation #Produces is already there and doesn't help either
Obtaining "MessageBodyWriter not found for media type=application/json" trying to send JSON object through JAX-RS web service - GENSON with #XmlAttribute had not the desired effect
I tried to keep the JSON object as simple as possible to avoid problems with arrays and complex objects -> No change
I still think it's a dependency problem here. However I'm out of ideas what could be the problem.
Unfortunately my last post was marked as duplicate although the problem and the solution was different. Therefore I'm posting a new question with the two solutions to hopefully help you avoid head banging at the table for several hours.
Preferred solution:
Apparently GF4 ships with MoxyJson which I didn't want to use. To integrate your own dependency - in my case Jackson - you need to disable the MoxyJson with the below code.
#ApplicationPath("/")
public class ApplicationConfig extends Application {
/**
* {#inheritDoc}
*/
#Override
public Map<String, Object> getProperties() {
final Map<String, Object> properties = new HashMap<String, Object>();
properties.put("jersey.config.server.disableMoxyJson", true);
return properties;
}
}
Then add your own dependencies, e.g. in my case only those two because the others are referenced by another lib I use.
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-json-provider</artifactId>
<version>2.6.2</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
<version>2.6.2</version>
</dependency>
Finally I made the mistake of not setting a value to the #JsonProperty annotations which will cause a No MessageBodyWriter found exception. To avoid that use the following ony relevant getters of your class.
#JsonProperty("randomName")
public String getRandomName(){
...
}
Alternative:
Worse than above you'll need to disable MoxyJson, register each service individually, and fix a Bug when using ResourceConfig of GF.
#ApplicationPath("/")
public class ApplicationConfig extends ResourceConfig {
/**
* The default constructor.
*/
public ApplicationConfig() {
// Disable Moxy and use Jackson
this.property(ServerProperties.MOXY_JSON_FEATURE_DISABLE, true);
// Register own provider classes
this.register(Fully.Qualified.Path.To.Your.Service.class);
// Register Jackson provider
// Workaround for GF4.1 bug for details: https://java.net/jira/browse/GLASSFISH-21141
final ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JaxbAnnotationModule());
this.register(new JacksonJaxbJsonProvider(mapper, JacksonJaxbJsonProvider.DEFAULT_ANNOTATIONS));
}
}
You'll need an additional dependency for the ResourceConfig class.
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-json-provider</artifactId>
<version>2.6.2</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
<version>2.6.2</version>
</dependency>
<dependency>
<groupId>org.glassfish.main.extras</groupId>
<artifactId>glassfish-embedded-all</artifactId>
<version>4.1.1</version>
<scope>provided</scope>
</dependency>
Finally the same as above - be aware to use #JsonProperty with a set value.
