Title Body

I'm working on trying to implement a JUnit test to check the functionality of a DAO. (The DAO will create/read a basic object/table relationship). The trouble I'm having is the persistence of the DAO (for the non-test code) is being completed through an in-house solution using Spring/Hibernate , which eliminates the usual *.hbm.xml templates that most examples I have found contain. Because of this, I'm having some trouble understanding how to setup a JUnit test to implement the DAO to create/read (just very basic functionality) to an in-memory HSQLDB . I have found a few examples, but the usage of the in-house persistence means I can't extend some of the classes the examples show (I can't seem to get the application-context.xml setup properly). Can anyone suggest any projects/examples I could take a look at (or any documentation) to further my understanding of the best way to implement this test functionality? I feel like this should be really simple, but I keep running into problems implementing the examples I have found. edit: Here's my solution for better readability, for anyone who needs a hand getting things going: My TestClass : @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = "classpath:applicationContextTest-Example.xml") @Transactional public class ExampleDaoTest extends AbstractTransactionalJUnit4SpringContextTests { @Resource(name = "sessionFactory") private SessionFactory exampleSessionFactory; @Resource(name = "exampleDao") private ExampleDao exampleDao; My applicationContext.xml file:  <bean id="exampleDao" class="org.myExample.ExampleDao"/>  <bean id="example_dataSource" class="org.apache.commons.dbcp.BasicDataSource">
