I'm trying to run a TestNG+Spring+JPA+Hibernate 'Hello World' test. The execution results in a NullPointerException, the tiles configurer bean fails.

Did a lot of googling, only thing found, people mentioned about cglib and/or asm jars in conflict with spring and hibernate dependencies. I don't think that is applicable here however my lib folder has the following jars, sorry not in order:

The test class is as follows:
#ContextConfiguration(locations = { "classpath:test-servlet.xml" })
public class FacultyDaoTest extends AbstractTransactionalTestNGSpringContextTests {
private final XLogger logger = XLoggerFactory.getXLogger(FacultyDaoTest.class);
#Inject
FacultyDAO facultyDao;
#BeforeClass
public void setUp() {
logger.entry();
System.out.println("Inside setup");
}
#Test(groups = { "fast" })
#Rollback(value = false)
public void createFaculty() {
Faculty f = new Faculty();
f.setFirstName("John");
f.setLastName("Frost");
f.setCpsoNumber("23198");
f = facultyDao.makePersistent(f);
assert(f.getId() > 0);
}
#Test(groups = { "fast" })
public void aFastTest() {
logger.entry();
logger.info("Inside a Fast test");
}
#Test(groups = { "slow" })
public void aSlowTest() {
logger.entry();
logger.info("Inside a Slow test");
}
}
Any pointers will be greatly appreciated.

Answer 1

Your test load a web app specific configuration file, but your test environment does not provide the required files:
You need to separate the Web Application specific configuration from the one the works wihtout web application context.
Then use for the test the one that works without Web Application.
For you that mean: remove the Tiles Configuration for the test configuration. Because in the test the /WEB-INF/tiles/tiles.xml file is not available.
