Autowiring issue with JUnit in a Spring Data JPA environment - spring

Question

i have issues with #autowired in my unit tests.
here are the relevant classes and xml files:
The Service Class:
#Service(value = "statusService")
public class StatusService implements DefaultService<Status> {
#Autowired(required = true)
private StatusRepository statusRepository;
public void save(Status value) {
statusRepository.save(value);
}
}
The Interface:
public interface DefaultService<T> {
#Transactional
void save(T value);
}
(i also tested a non generic interface, but the result was the same.)
The Test Class:
#ContextConfiguration(locations={"**/WEB-INF/applicationContext.xml", "**/WEB-INF/hibernate-context.xml"})
#RunWith(SpringJUnit4ClassRunner.class)
#TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
#Transactional
public class StatusServiceTest
{
#Autowired
private StatusService statusService;
#Test
public void test()
{
Status s = new Status();
s.setDescription("desc");
s.setStatus("status");
statusService.save(s);
}
}
The Application Context:

i tried to autowire the interface (the generic one too) instead of the Service Class, cause i´ve read that there probably are issues.
i tried it with an #Resource, same stacktrace
i tried writting a non generic interface
...
i find it strange that the, application runs perfectly on an tomcat server as a web application. no problems there saving and deleting Objects. I still don´t understand why the tests aren´t working.
plz help ;) thx

By default, locations parameter of #ContextConfiguration annotation is assuming classpath: protocol, so you need to explicitly specify file: protocol when loading files not in the classpath, e.g. context located within WEB-INF folder:
#ContextConfiguration(locations={
"file:**/WEB-INF/applicationContext.xml", "file:**/WEB-INF/hibernate-context.xml"})
#RunWith(SpringJUnit4ClassRunner.class)
#TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
#Transactional
public class StatusServiceTest
