ActiveObjectsJUnitRunner - EntityManager is not injected into tests.

[Plamen Petkov]

Hello everyone.
I am developing a plugin for Confluence and following this guide https://developer.atlassian.com/server/framework/atlassian-sdk/getting-started-with-active-objects/, but I am having trouble with testing.
The problem is that the ActiveObjectsJUnitRunner.class class doesn't inject EntityManager and throw NullPointerException at setUp () {} method. According to this guide ActiveObjectJUnitRunner.class should inject EntityManager.
Surely I do something wrong or something remains to be done.

Thanks in advance of your help.

Those are my pom test dependencies:

and that is my test class:

//@Jdbc(DerbyEmbedded.class)

class ConfluencerPersistenceImplTest {

    private ConfluencerPersistenceImpl objectToTest;

    private EntityManager entityManager;

    @Test
    void getAll() {
    }

    @Test
    void save() {
    }

    @Test
    void remove() {
    }

    @BeforeEach
    public void setUp() {
        assertNotNull(entityManager);
        objectToTest = new ConfluencerPersistenceImpl(new TestActiveObjects(entityManager));

    }

    public static final class ConfluencerPersistenceImplTestDatabaseUpdater implements DatabaseUpdater {
        @Override
        public void update(EntityManager entityManager) throws Exception {
            entityManager.migrate(EventUserServ.class);
        }
    }
}

the error message: 

org.opentest4j.AssertionFailedError: expected: not <null>

shouldnt this be an issue?

[Plamen Georgiev Petkov]

If someone have this problem , here is a solution. (although this should not be a solution, if there is a new version of junit)
I make it work with downgrading of junit. I have no problems with junit4 (org.junit.*), EntityManager was injected by ActiveObjectsJUnitRunner, but I don't understand why with junit5 (org.junit.jupiter.api.*) EntityManager is not injected.
Is there another way to test persistence with JUnit5?
Is there another way to inject the EntityManager with JUnit5 ?
All my tests are writed on junit5 , except this one.

worked test class:

package com.cis.confluence.plugins.persistence;

import com.atlassian.activeobjects.external.ActiveObjects;
import com.atlassian.activeobjects.test.TestActiveObjects;
import net.java.ao.EntityManager;
import net.java.ao.test.junit.ActiveObjectsJUnitRunner;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import static org.junit.jupiter.api.Assertions.*;


@RunWith(ActiveObjectsJUnitRunner.class)
public class ConfluencerPersistenceImplTest {

    private ConfluencerPersistenceImpl objectToTest;

    private EntityManager entityManager;

    private ActiveObjects ao;

//changed from org.junit.jupiter.api.Test to org.junit.Test
    @Test
    public void getAll() {

    }

//changed from org.junit.jupiter.api.Test to org.junit.Test
    @Test
    public void save() {
    }

//changed from org.junit.jupiter.api.Test to org.junit.Test
    @Test
    public void remove() {
    }

//changed from org.junit.jupiter.api.BeforeEach to org.junit.Before
    @Before
    public void setUp() {
        assertNotNull(entityManager);

        ao = new TestActiveObjects(entityManager);
        objectToTest = new ConfluencerPersistenceImpl(ao);
    }  
}

another interface :

import net.java.ao.RawEntity;

public interface ActiveObject extends RawEntity<ActiveObjects>{

}
