JPA 单元测试用例删除操作需要但未调用

Question

在尝试使用JPA创建用于删除的junit测试用例时，我遇到了一些问题。在我的服务类中，我使用的是 JPA 提供的缺省函数：

public void delete(Long id) {

        log.debug("Request to delete Enroll : {}", id);

        enrollRepository.deleteById(id);

}

然后我的单元测试，我试图模拟一个对象，然后执行删除：

@Test

public void testDeleteEnrollExpectSuccess() {

    Enroll enroll = prepareEnrollWithBedAllocation();

    enrollService.delete(enroll.getId());

    verify(enrollRepository, times(1)).delete(enroll);

}

我打算像这样嘲笑注册对象：

private Enroll prepareEnrollWithBedAllocation() {

    LocalDateTime localDateTime = LocalDateTime.now();

    ZonedDateTime zonedDateTime = ZonedDateTime.of(localDateTime, ZoneId.of("UTC"));

    Enroll enroll = new Enroll();

    enroll.setId(new Long(1));

    enroll.seteDate(zonedDateTime);

    enroll.setEbStartdt(zonedDateTime);

    enroll.setEbEnddt(zonedDateTime);

    enroll.setBed(prepareBed());

    enroll.setPatient(preparePatient());

    enroll.setDoc(prepareDoc());

    enroll.seteCondition("Normal");

    return enroll;

}

但是，我收到这些错误消息，并且我的测试用例失败：

Wanted but not invoked:

enrollRepository.delete(

    Enroll{id=1, eCondition='Normal', eRemarks='null', ebStartdt='2019-04-09T16:40:32.703Z[UTC]', ebEnddt='2019-04-09T16:40:32.703Z[UTC]', eDate='2019-04-09T16:40:32.703Z[UTC]'}

);

-> at com.team.generated.service.EnrollServiceTest.testDeleteEnrollExpectSuccess(EnrollServiceTest.java:61)

However, there was exactly 1 interaction with this mock:

enrollRepository.deleteById(1L);

-> at com.team.generated.service.EnrollService.delete(EnrollService.java:74)

有什么想法吗？谢谢！

该错误本身就说明了：您正在验证该方法：delete(Long id)verify(enrollRepository, times(1)).delete(enroll);但是，您的服务对象调用方法：deleteById()enrollRepository.deleteById(id);我想你想这样做：@Testpublic void testDeleteEnrollExpectSuccess() {     Enroll enroll = prepareEnrollWithBedAllocation();     enrollService.delete(enroll.getId());     verify(enrollRepository, times(1)).deleteById(enroll.getId()); }
