ActiveObjectsJUnitRunner - EntityManager is not injected into tests.

Plamen Petkov_201rlx

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:

package com.cis.confluence.plugins.persistence;

import com.atlassian.activeobjects.test.TestActiveObjects;
import net.java.ao.EntityManager;
import net.java.ao.test.jdbc.Data;
import net.java.ao.test.jdbc.DatabaseUpdater;

import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import static org.junit.jupiter.api.Assertions.*;


@RunWith(ActiveObjectsJUnitRunner.class)
@Data(ConfluencerPersistenceImplTest.ConfluencerPersistenceImplTestDatabaseUpdater.class)
//@Jdbc(DerbyEmbedded.class)
//@NameConverters
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>

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.
