Hi again,
I have evolved a bit my example and could managed to test UserRepository
from Gerhard ee6-ds-dm, sources are here:
https://github.com/rmpestano/ee6-ds-demo/
<https://github.com/rmpestano/ee6-ds-demo/>
first thing i did was to disable application EntityManagerProduces in unit
tests (remember i want to use my in memory db for tests):
@Exclude(ifProjectStage = ProjectStage.UnitTest.class)
public class EntityManagerProducer {
@PersistenceContext(unitName = "demoApplicationPU")
private EntityManager entityManagerProxy;
@Produces
public EntityManager exposeDependentEntityManager() {
return entityManagerProxy;
}
}
then i've create my producer in test sources:
public class TestEntityManagerProducer {
private EntityManager entityManager;
@Produces
@ApplicationScoped
public EntityManager exposeDependentEntityManager()
{
entityManager =
Persistence.createEntityManagerFactory("TEST_PU").createEntityManager();
return entityManager;
}
public void closeEntityManager(@Disposes EntityManager entityManager)
{
if (entityManager.isOpen())
{
entityManager.close();
}
}
}
And here is my repository test:
@RunWith(CdiTestRunner.class)
@TestControl(projectStage = ProjectStage.UnitTest.class)
public class UserRepositoryTest {
@Inject
UserRepository userRepository;
@Before
public void tearUp(){
User u = new User("testUser","first","last");
userRepository.save(u);
assertNotNull(u.getId());
assertEquals(userRepository.count(), 1);
}
@After
public void tearDown(){
userRepository.getEntityManager().remove(userRepository.findUser("testUser"));
}
@Test
public void shouldFindUser() {
User user = userRepository.findUser("testUser");
assertNotNull(user);
assertEquals(user.getUserName(),"testUser");
}
}
I have added deltaspike-jpa module to the project to have transaction
support:
@Transactional
public User save(User user) {
if (user.isTransient()) {
entityManager.persist(user);
} else {
user = entityManager.merge(user);
}
return user;
}
without it, i could not insert users during tests (@Before)
here is test persistence.xml:
<persistence version="2.0"
xmlns="http://java.sun.com/xml/ns/persistence";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd";>
<persistence-unit name="TEST_PU" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>org.os890.demo.ee6.ds.domain.user.User</class>
<properties>
<property name="hibernate.dialect"
value="org.hibernate.dialect.H2Dialect" />
<property name="javax.persistence.jdbc.driver"
value="org.hsqldb.jdbcDriver" />
<property name="javax.persistence.jdbc.url"
value="jdbc:hsqldb:mem:." />
<property name="javax.persistence.jdbc.user" value="sa" />
<property name="javax.persistence.jdbc.password" value="" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.connection.shutdown" value="true"/>
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
</properties>
</persistence-unit>
</persistence>
finally the dependencies I've added to project:
<dependency>
<groupId>org.apache.deltaspike.modules</groupId>
<artifactId>deltaspike-jpa-module-api</artifactId>
<version>${ds.version}</version>
</dependency>
<dependency>
<groupId>org.apache.deltaspike.modules</groupId>
<artifactId>deltaspike-jpa-module-impl</artifactId>
<version>${ds.version}</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.2.18.Final</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<version>1.8.0.10</version>
<scope>test</scope>
</dependency>
Any other advices?
I hope it helps someone ;)
