Software Architecture in Java: Design & Development

Develop the Data Access Tier

Explore developing the data access tier by implementing CRUD operations with Hibernate in a Java Spring environment. Understand how to write test cases for data retrieval, insertion, deletion, and updates without hardcoding identifiers. Gain practical skills in managing one-to-one unidirectional relationships through test-driven development.

We'll cover the following...

Next, we will look at the data access tier. We will start with the test case for the “find all records” operation. Since this is the first function that is being developed as part of the test-driven development, we let it return zero for the find all records operation. In the following functions, we will build the CRUD operations in sequence.

Find all records operation

Java
@RunWith( SpringJUnit4ClassRunner.class )

@ContextConfiguration( locations = { "classpath:context.xml" } )

@TransactionConfiguration( defaultRollback = true )

@Transactional

public class BookDaoImplTest {



	@Autowired

	private BookDao dao;



	@Test

	public void testGetAll() {

		Assert.assertEquals(0L, dao.getAll().size());

	}

}

We will see how to write the conforming data access operation for the test above. The BookDao is an interface containing the method ...
