It's my testHelper:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath*:WEB-INF/spring/appServlet/servlet-context.xml" })
public class TestHelper {
@Mock
private UserDaoImpl userDaoImpl;
@InjectMocks
private Helper helper=new Helper();
private MockMvc mockMvc;
String msg = "Success";
int status = 200;
ResponseMessage message = new ResponseMessage();
@Before
public void setup() {
MockitoAnnotations.initMocks(this);
this.mockMvc = MockMvcBuilders.standaloneSetup(helper).build();
}
@Test
public void testCategories() throws Exception {
message = helper.getCategories(0);
assertNotNull(message);
Assert.assertEquals(status, message.getStatus());
Assert.assertEquals(msg, message.getMessage());
} }
It's my Helper class:
public class Helper extends BaseHelper {
@Autowired
private UserDao userDao;
private static final Logger logger = LoggerFactory
.getLogger(Helper.class);
public ResponseMessage getCategories(int categoryID) {
logger.info("**Helper getCategories() entry*****");
ResponseMessage message;
try {
List<Category> categories = userDao
.getCategories(categoryID);
String jsonConverted = Utility
.convertToJsonString(categories);
com.fasterxml.jackson.databind.ObjectMapper mapper = new com.fasterxml.jackson.databind.ObjectMapper();
Object obj = mapper
.readValue(
jsonConverted,
new TypeReference<List<Category>>() {
});
message = prepareResponse(obj, 200, "Success");
} catch (Exception e) {
logger.error("****Exception in Helper getCategories() : "
+ e.getStackTrace());
message = prepareResponse( null, 500,
e.getMessage());
}
logger.info("***Helper getCategories() exit****");
return message;
}
}
It's my UserDaoImpl class:
public class UserDaoImpl implements UserDao {
private static Properties applicationProperties;
static {
applicationProperties = Utility.loadAppProperties();
}
public List<Category> getCategories(int category_id) {
Session session = null;
List<Category> categories = null;
try {
session = sessionFactory.getCurrentSession();
logger.info("enter into getCategories from method's body");
Transaction tx = session.beginTransaction();
if (!Utility.isZeroInt(category_id)) {
List list = session.createCriteria(Category.class).add(Restrictions.eq("category_id", category_id))
.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY).list();
categories = list;
} else {
List list = session.createCriteria(Category.class).setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY)
.list();
categories = list;
}
tx.commit();
} catch (Exception e) {
throw new DataException("Unable to get categories. Please try after some time.");
}
logger.info("exit from getCategories method's body");
return categories;
}
}
When i test my helper class then i got the error on the applicationProperties = Utility.loadAppProperties(); in the userdaoimpl class. and the error is
java.lang.ExceptionInInitializerError. This error are generate at the time of load the property file in userdaoimpl class.
this is the stack trace
java.lang.ExceptionInInitializerError
