我想为 DAO 编写单元测试。但是在我们的项目中，我们有超过 200 个 DAO 和 200 个模型类。我们使用 jpaRepository 来编写 DAO。但是我在运行单元测试时遇到了问题。我花了很多时间来创建应用程序上下文。我有个主意。我只创建一个我想测试的 bean DAO，而不是创建所有 DAO。但是 jpa:repository 的 DAO 是接口，所以我不能创建一个类是接口的 bean。如果创建扩展 jpa:reponsitories 的 bean 是不可能的，你能建议我其他更快地运行单元的方法吗？我的单元测试：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:META-INF/spring/testContext.xml"})
@TransactionConfiguration(defaultRollback = true)
// Importance, as the transaction will be rollback for each test
// give us a clean state.
@Transactional
public class CommunicationDetailDAOTest
{
@Autowired
CommunicationDetailDAO communicationDetailDAO;
@Test
public void testSomeThing()
{
System.out.println("helloworld");
}
}
