单元测试

1.IDEA下载Junit插件

2.选定代码自动生成代码

3.写入测试语句测试功能执行效果

代码示例：

public class UserDaoTest {

    @Before
    public void setUp() throws Exception {
    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public void login() {
        UserDao dao = new UserDaoImpl();
        RootUser rootUser = new RootUser();
        rootUser.setId(1);
        rootUser.setUserid("123");
        rootUser.setPassword("123");
        rootUser.setStatus("0");
        Assert.assertEquals("0",dao.login("123","123"));
        System.out.println("登录用户："+rootUser.getUserid());
    }

    @Test
    public void registerstu() {
        UserDao dao = new UserDaoImpl();
        Student student = new Student();
        for(int i = 0;i<10;i++){
            student.setUsername("123"+i);
            student.setPassword("123"+i);
            student.setName("x"+i);
            student.setSex("男");
            student.setBanji("1"+i);
            student.setNianji("1"+i);
            student.setStatus("1");
            Assert.assertTrue(dao.registerstu(student));
            System.out.println("添加username："+student.getUsername());
        }


    }

    @Test
    public void getStu() {
        UserDao dao = new UserDaoImpl();
        Student student = new Student();
        List<Student> list = new ArrayList<Student>();
        Assert.assertNotNull(dao.getStu());
        list = dao.getStu();
        for (Student student1 : list) {
            System.out.println(student1);
        }
    }

    @Test
    public void deletes() {
        UserDao dao = new UserDaoImpl();
        for(int i = 50;i<60;i++) {
            Assert.assertTrue(dao.deletes(1+i));
            int j = i+1;
            System.out.println("删除id:"+j);
        }
    }

    @Test
    public void updatestu() {
        UserDao dao = new UserDaoImpl();
        for(int i = 50;i<60;i++){
            Assert.assertTrue(dao.updatestu(1+i,"321"+i,"321"+i,"xxx+i","女","2"+i,"2"+i));
            int j = i+1;
            System.out.println("更新id："+j);
        }
    }
}
