I am trying to test an entity EJB3 with Spring.
The EJB itself does not uses Spring and I would like to keep duplications of the production JPA configuration minimal (ie not duplicating persistence.xml for exemple).
My unit tests seems to work but even though my unit tests should be transactionnal, data is persisted between the various test methods ...
Here is my entity :
package sample;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
@Entity
public class Ejb3Entity {
public Ejb3Entity(String data) {
super();
this.data = data;
}
private Long id;
private String data;
@Id
@GeneratedValue
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getData() {
return data;
}
public void setData(String data) {
this.data = data;
}
}
My unit test :
package sample;
import static org.junit.Assert.*;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.transaction.annotation.Transactional;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"/appContext.xml"})
@Transactional
public class Ejb3EntityTest {
@PersistenceContext
EntityManager em;
@Before
public void setUp() throws Exception {
Ejb3Entity one = new Ejb3Entity("Test data");
em.persist(one);
}
@Test
public void test1() throws Exception {
Long count = (Long) em.createQuery("select count(*) from Ejb3Entity").getSingleResult();
assertEquals(Long.valueOf(1l), count);
}
@Test
public void test2() throws Exception {
Long count = (Long) em.createQuery("select count(*) from Ejb3Entity").getSingleResult();
assertEquals(Long.valueOf(1l), count);
}
}
and my appContext.xml :

When I run my test, test2 fails because it finds 2 entity where I expected only one (because the first one should have been rollbacked ...)
I have tried a lot of different configurations and this one seems to be the most comprehensive I can get ... I have no other ideas. Do you ?
