集成测试db h2

Question

您好我想在h2中对我的数据库进行集成测试。但是我的方法有些问题。 我的集成测试代码：

@RunWith(SpringRunner.class)
@DataJpaTest
public class Team_database_integration_test {

    @MockBean
    private TeamRepository teamRepository;

    @Autowired
    private TestEntityManager testEntityManager;

    @Test
    public void testDb() {
        Team team = new Team(1L, "teamName", "teamDescription", "krakow", 7);
        testEntityManager.persist(team);
        testEntityManager.flush();

        Assert.assertEquals(1L, teamRepository.findById(team.getId()));
    }
}

我的错误：

java.lang.AssertionError: 
Expected :1
Actual   :Optional.empty

我认为原因在于我的服务方法findbyid：

public Optional<TeamDto> findTeamById(Long id) {
        Assert.notNull(id, "ID must exist ");
        return teamRepository
                .findById(id)
                .map(p -> modelMapper.map(p, TeamDto.class));
    }
