Question

数据库表

CREATE TABLE `test` (
  `b_index` int(10) NOT NULL AUTO_INCREMENT,
  `password` varchar(40) DEFAULT NULL,
  PRIMARY KEY (`b_index`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8;

并插入主板 mybatis映射器

<insert id="insertBoard" parameterType="hashmap">
    <![CDATA[
        INSERT INTO board
        (
            password
        )
        VALUES
        (
            #{password}
        )
    ]]>
</insert>

Junit测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:/application-context.xml")
public class BoardServiceTest {
    @Autowired
    private BoardService boardService;

    private static final String TEST_PASSWORD = "test";

    private Board board = null; // test vo object

    @Before
    @Transactional
    @Rollback
    public void setup() throws Exception {
        Board board = null; // test vo object

        board = new HistoryBoard();
        board.setPassword("TEST");

        this.board = board;

        boardService.insertBoard(board);
    }
}

问题是我在Junit Test Class 'BoardServiceTest'

中插入insertBoard

总是b_index设置'0'

所以当我在 BoardServiceTest类

中尝试这样的时候

@Test
@Transactional
public void validPassword() {
    String pwd = boardService.selectPassword(board);

    assertEquals(TEST_PASSWORD, pwd);
}

此测试始终为FALSE，因为板对象索引为'0'

但实际上b_index不是'0'，因为AUTO_INCREMENT不是'0'

@Test
@Transactional
public void getAllBoard() {
    List<Board> selectAllBoardList = boardService.selectAllBoardList();

    System.out.println("TEST : " + selectAllBoardList.get(0).getB_index());

    assertEquals(false, selectAllBoardList.isEmpty());
}

此测试日志TEST : 10

时

如何在这种情况下在JUnit中测试数据库？

当我尝试JUnit测试时，总是需要设置AUTO_INCREMENT = 0吗？

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:/application-context.xml")
public class BoardServiceTest {
    @Autowired
    private BoardService boardService;

    private static final String TEST_PASSWORD = "test";

    private Board board = null; // test vo object

    @Before
    @Transactional
    @Rollback
    public void setup() throws Exception {
        Board board = null; // test vo object

        board = new HistoryBoard();
        board.setPassword("TEST");

        boardService.insertBoard(board);

        this.board = board;
    }
}

在insertBoard mybatis之前

键是自动设置AUTO_INCREMENT PK

Spring MVC Junit Test DB自动增量
