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：@Testpublic 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());
}
