I'm using spring mvc.
I want to test my service with Junit.
I want to test the inclusion of a new user
I write the class test:
#ContextConfiguration("/dispatcher-servlet.xml")
public class ServizioUtenteTest {
#Autowired
private ServizioUtente servizioutente;
#Test
public void testAggiungiUtente() {
//fail("Not yet implemented");
Utente utente=new Docente();
utente.setCognome("Professore");
utente.setPassword("tetxts");
utente.setUsername("xxxx");
servizioutente.aggiungiUtente(utente);
}
#Test
}
When I run the test I get:
java.lang.NullPointerException
at org.rol.test.ServizioUtenteTest.testAggiungiUtente(ServizioUtenteTest.java:61)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)
at java.lang.reflect.Method.invoke(Unknown Source)
....)
The error is thrown on the line, why?
help me!?
You are missing SpringJUnit4ClassRunner:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration("/dispatcher-servlet.xml")
public class ServizioUtenteTest {

I tried to initialize my database using code bellow
#Component
public class DataBase {
#Transactional
#PostConstruct
public void init() {
Query nativeQuery = entityManager.createNativeQuery("Native SQL Query");
nativeQuery.executeUpdate();
}
}
and I got this runtime exception
Caused by: javax.persistence.TransactionRequiredException: Executing an update/delete query

but injecting DataBase and calling init function is working fine!
#Component
public class TestClass {
#Autowired
private DataBase dataBase;
#PostConstruct
public void test() {
dataBase.init();
}
}
why this is happening!,is this a bug or there is some reason?
I am using Spring Boot and configured my Application like this:
#Configuration
#EnableAutoConfiguration
#EnableTransactionManagement
#ComponentScan
#EntityScan("ch.xy.model")
public class Application {
#Autowired
private ImportDAO importDao;
}
ImportDAO looks like that:
#Repository
public class ImportDAO {
#PersistenceContext
private EntityManager em;
#Transactional
void removeTempoAccounts() {
Query q = em.createQuery("DELETE FROM TempoAccount t WHERE t.manual = false");
q.executeUpdate();
}
}
But when removeTempoAcconts is executed I get:

What's wrong with my configuration?
#Transactional
void removeTempoAccounts() {
Method had default visibility. Therefore the proxy mechanism was not active!
After changing to public everthing works as expected!
Try to use the #Transactional annotation from Spring package
like #org.springframework.transaction.annotation.Transactional
Then it should work
I have a project which using Test Context Framework.
I'm execute the test using Run As -> JUnit Test but it show initializationError();

How to run the test ?
It looks like you might be running against an unsupported version of JUnit.
What version of spring-test are you using?
What version of junit are you using?
FYI: Spring 2.5 requires JUnit 4.4; Spring 3.0 and higher require JUnit 4.5 or higher.
I'm trying to deploy a bean that uses #Interceptros annotation in Jboss.
According to documentation I've created beanRefContext.xml and here is Bean code
#Stateless
#LocalBean
#Interceptors(SpringBeanAutowiringInterceptor.class)
public class ClienteBean implements ClienteBeanLocal {
public ClienteBean() {
// TODO Auto-generated constructor stub
}
#Autowired
private IClienteDAO cliente;
#Override
public List<ClienteDTO> selectALL() throws Exception {
return cliente.selectALL();
}
}
I am deploying it inside an EAR. When I try to deploy in Jboss 6 I get the following error:

How can I solve it?
Seems JBoss is not seeing SpringBeanAutowiringInterceptor.class. In your EAR file put your spring jars on the lib directory. See if that works.
If you are using maven to assemble your EAR file you can do something like this:

I am working on a project that uses Spring and Hibernate. I have an abstract DAO that contains SessionFactory. I need to mock SessionFactory or Session for my unit test. But I have not been successful so far. Below is the code. Anyone has any idea? Thank you.
Here is my AbstractDAO
public abstract class AbstractDAO {
protected JdbcTemplate jdbcTemplate;
protected SessionFactory sessionFactory;
protected NamedParameterJdbcTemplate namedParameterJdbcTemplate;
...
#Autowired
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}}
And here is my ConcreteDAO
public class LoginDAO extends AbstractDAO implements InitializingBean {
...
public User getLoggedinUserByUserid(Long userid){
log.info("in getLoggedinUserByUserid");
User result = null;
Session session = sessionFactory.openSession();
try {
session.beginTransaction();
result = (User) session.get(User.class, userid);
session.getTransaction().rollback();
session.close();
} catch (Exception e) {
log.error(e,e);
session.getTransaction().rollback();
session.close();
}
return result;
}
...}
and here is my test class
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = { "LoginDAOTest-context.xml" })
#PrepareForTest({SessionFactory.class, Session.class, Transaction.class})
public class LoginDAOTest2 extends BaseDAO {
private static final Logger log = Logger.getLogger(LoginDAOTest2.class);
#Rule
public PowerMockRule rule = new PowerMockRule();
private LoginDAO loginDAO = new LoginDAO();
private SessionFactory mockedSessionFactory;
private Session mockedSession;
private Transaction mockedTransaction;
#Autowired
public void setSessionFactory(SessionFactory sessionFactoryCore) {
mockedSessionFactory = PowerMockito.mock( sessionFactoryCore.getClass());
mockedSession = PowerMockito.mock(Session.class);
PowerMockito.doReturn(mockedSession).when(mockedSessionFactory).openSession();
PowerMockito.doReturn(mockedTransaction).when(mockedSession).beginTransaction();
loginDAO.setSessionFactory(this.mockedSessionFactory);
}
#Test
public void shouldRollbackInGetLoggedinUserByUseridWhenSessionThrowsException() {
// Given
PowerMockito.doThrow(new Exception()).when(mockedSession).get(User.class, 12L);
// When
loginDAO.getLoggedinUserByUserid(12L);
// Then
verify(mockedTransaction, times(1)).rollback();
}
}
and here is the result of junit.

Why don't do this :
#Before
public void setUp() {
mockedSessionFactory = Mockito.mock(SessionFactory.class);
mockedSession = Mockito.mock(Session.class);
mockedTransaction = Mockito.mock(Transaction.class);
Mockito.when(mockedSessionFactory.openSession()).thenReturn(mockedSession);
Mockito.when(mockedSession.beginTransaction()).thenReturn(mockedTransaction);
loginDAO.setSessionFactory(this.mockedSessionFactory);
}
instead of :
#Autowired
public void setSessionFactory(SessionFactory sessionFactoryCore) {
mockedSessionFactory = PowerMockito.mock( sessionFactoryCore.getClass());
mockedSession = PowerMockito.mock(Session.class);
PowerMockito.doReturn(mockedSession).when(mockedSessionFactory).openSession();
PowerMockito.doReturn(mockedTransaction).when(mockedSession).beginTransaction();
loginDAO.setSessionFactory(this.mockedSessionFactory);
}
In addition, it allows you to not use powermock.
Interesting part is here :

It means that powermock is using an internal class that is not available in the mockito distribution your are using.
From that information I gather you are using Mockito 1.9.5-rc1, with some other recent Powermock release. As of now, Johan din't released a newer version of Powermock that take care of the changes that were made in Mockito 1.9.5-rc1.
These refactoring changes in Mockito were made to help the introduction of the MockMaker API, which allows a third party to provide his own mock factory, bytecode engine or else to create mocks.
See the documentation here : http://docs.mockito.googlecode.com/hg/1.9.5-rc1/org/mockito/Mockito.html
So for now, you should use Mockito 1.9.0 if you are using Powermock.
