SpringJunitTest

1.用MockBean和assert，而不是输出

import org.springframework.boot.test.mock.mockito.MockBean;
MockBean

import static org.junit.Assert.assertEquals;
assertEquals(expected,actual);

2.涉及到对数据库的修改

测试数据回滚要加@Transactional
(import org.springframework.transaction.annotation.Transactional;)
而不是@RollBack
(import org.springframework.test.annotation.Rollback;)
