Question

我必须为我想要的项目编写一些dao测试：

从数据库创建DDL架构（MySQL）;
在内存中的另一个测试数据库中创建表（H2）;
将一些数据发送给数据库;
选择刚插入的项目;
检查此项目的圆顶数据。

这是我的测试：

public class BridgeDBTest {

    private static String JDBC_DRIVER;
    private static String JDBC_URL;
    private static String USER;
    private static String PSWD;
    private static final Logger logger = LoggerFactory.getLogger(BridgeDBTest.class);

    @BeforeGroups(groups = "bridgeDB")
    public void init(){
        try {
            JDBC_DRIVER = org.h2.Driver.class.getName();
            JDBC_URL = "jdbc:h2:mem:test;DB_CLOSE_DELAY=-1";
            USER = "root";
            PSWD = "";

            new HibernateTestUtil().setDialect("org.hibernate.dialect.HSQLDialect")
                    .translateCreateDllToOutputStream(new FileOutputStream(new File("src/test/resources/createSchema.sql")));

            RunScript.execute(JDBC_URL, USER, PSWD, "src/test/resources/createSchema.sql", Charset.forName("UTF8"), false);

            insertDataset(readDataSet());

        }
        catch (Exception expt) {
            expt.printStackTrace();
            logger.error("!!!" + expt);
            throw new RuntimeException(expt.getMessage());
        }
    }


    @Test(groups = "bridgeDB")
    public void getItem(){
        BridgeDAOImpl dao = new BridgeDAOImpl();
        dao.setSessionFactory(new HibernateTestUtil().getSessionFactory());

        try {
            Bridge bridge = dao.get(1L);
            assert(bridge.getName().equals("TEST-CN-DEVBOX01"));

        } catch (ServiceException e) {
            e.printStackTrace();
        }
    }

    @AfterGroups(groups = "bridgeDB")
    public void dropTables(){
        try {
            new HibernateTestUtil().setDialect("org.hibernate.dialect.HSQLDialect")
                    .translateDropDllToOutputStream(new FileOutputStream(new File("src/test/resources/dropSchema.sql")));
        }
        catch (Exception expt) {
            expt.printStackTrace();
            logger.error("!!!" + expt);
            throw new RuntimeException(expt.getMessage());
        }
    }

    private IDataSet readDataSet() throws Exception{
        return new FlatXmlDataSetBuilder().build(new File("src/test/resources/datasetForTest.xml"));
    }

    private void insertDataset(IDataSet dataSet) throws Exception{
        IDatabaseTester databaseTester = new JdbcDatabaseTester(JDBC_DRIVER, JDBC_URL, USER, PSWD);
        databaseTester.setSetUpOperation(DatabaseOperation.CLEAN_INSERT);
        databaseTester.setDataSet(dataSet);
        databaseTester.onSetup();
    }
}

BridgeDAOImpl使用了来自HibernateUtil的课程src/main/...，但我需要使用HibernateTestUtil中的课程src/test/...。修改后的HibernateUtil适合我的测试（我为Configuration类设置了参数）。

BridgeDAOImpl（参见try区块中的5行）：

public class BridgeDAOImpl extends GenericDAOImpl<Bridge, Long> implements BridgeDAO {
//...
public SearchResult<Bridge> list(int from, int limit, String filter, String order, Long authId) throws ServiceException {

        SearchResult<Bridge> results = null;
        Search search = new Search(Bridge.class);

        Session session = getSessionFactory().getCurrentSession();
        Transaction transaction = null;

        try {
            transaction = session.beginTransaction();

            search.setFirstResult(from);
            search.setMaxResults(limit);
            HibernateUtil.buildSearch(filter, order, search, aliases);
            results = searchAndCount(search);

            transaction.commit();
        }
        catch (Exception expt) {
            logger.error("!!!", expt);
            if (transaction != null) {
                transaction.rollback();
            }
            throw new ServiceException(expt.getMessage());
        }
        finally {
//            session.close();
        }
        return results;
    }
    //...
}

如何在不修改的情况下测试我的dao？有什么想法吗？

如何测试使用无法上课的DAO？
