Writing DB Unit Tests with Spring : java.lang.IllegalStateException: Failed to load ApplicationContext

Question

I have been really stuck at trying to get Spring DBUnit test to work for testing my dao functionality. However, after so many attempts now I am stuck at this weird saying unable to load application context :

Dao which I want to test:

public interface IMyDao
{
 List<Person> findAll();
}
@Repository("MyDao")
public class MyDaoImpl implements IMyDao
{
 @Autowired
 private SessionFactory sessionFactory;
 @Override
 public List<Person> findAll()
 {
 Query query = sessionFactory.getCurrentSession().createQuery("from Person");
 return (List<Person>) query.list();
 }
}

Data set file which I am using: dataset.xml

<dataset>
 <person id="25" name="Dane" phone="61458972564"/>
 <person id="21" name="Sam" phone="61458972564"/>
</dataset>

Application context for tests: applicationContext-test.xml

<?xml version="1.0" encoding="UTF-8"?>

 </property>
 <property name="packagesToScan">

 </property>
 </bean>
</beans>

The actual test class :

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext-test.xml")
@TestExecutionListeners({DependencyInjectionTestExecutionListener.class,
 DirtiesContextTestExecutionListener.class,
 TransactionalTestExecutionListener.class,
 DbUnitTestExecutionListener.class})
@DatabaseSetup("dataset.xml")
public class MyDaoImplTest
{
 @Autowired
 private MyDao dao;
 @Test
 @Transactional
 public void testA()
 {
 System.out.println("Hello");
 }
}

However, when I run this, I get this weird exception saying unable to load application context.

Reading the line :

java.lang.IncompatibleClassChangeError: class org.springframework.core.type.classreading.ClassMetadataReadingVisitor has interface org.springframework.asm.ClassVisitor as super class

it seems that there is a conflict in version between spring core and spring asm. if your are using maven run dependency:tree to verify what jars are used .

• OneMoreError: I have added the following dependency in my module: <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.2.3.RELEASE</version> <scope>test</scope> </dependency>. The parent module has version 3.1.1.RELEASE. If I take out this dependency, then I get : java.lang.NoClassDefFoundError: org/springframework/core/type/AnnotatedTypeMetadata. What should I do ?
• hasnae: Could you please add all your spring dependencies?
