我正在尝试使用Arquillian和Wildfly 8.2实现一个小小的集成测试 通过实体管理器保持和查找工作,但使用任何类型的查询都找不到任何东西。
我的测试班:
@RunWith(Arquillian.class)
public class VoteServiceTest {
@Inject
private EntityManager entityManager;
@Before
public void createEntityManager() {
entityManager.persist(user);
entityManager.persist(vote);
}
@Test
public void justATest() {
Assert.assertTrue(entityManager.find(User.class, 1L) != null); // Works
Assert.assertTrue(entityManager.find(Vote.class, 4L) != null); // Works
Assert.assertTrue(entityManager.createQuery("SELECT c FROM Vote c", Vote.class).getResultList() == 1); // Fails
}
@Deployment
public static JavaArchive createDeployment() {
return ShrinkWrap.create(JavaArchive.class).addPackages(true, "de/...")
.addAsResource("META-INF/persistence.xml", "META-INF/persistence.xml")
.addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
}
}
的persistence.xml:
<persistence ...>
<persistence-unit name="test" transaction-type="RESOURCE_LOCAL">
<class>de....Vote</class>
<class>de....User</class>
<properties>
<property name="hibernate.hbm2ddl.auto" value="create"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
<property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver"/>
<property name="hibernate.connection.url" value="jdbc:hsqldb:mem:test"/>
<property name="hibernate.show_sql" value="true"/>
</properties>
</persistence-unit>
</persistence>
我错过了什么?
答案 0 :(得分:2)
答案很简单,我忘了使用交易。更改代码后,我的查询返回了我期望的实体。
@PersistenceContext
protected EntityManager em;
@Inject
protected UserTransaction utx;
@Before
public void preparePersistenceTest()
throws Exception {
utx.begin();
em.joinTransaction();
em.persist(user);
em.persist(vote);
utx.commit();
// reset the persistence context (cache)
em.clear();
}
