Mockito mock 没有正确匹配参数（？）

Question

我正在尝试在服务层中存根一个方法来测试另一个对象：

@SpringBootTest
@RunWith(JUnitPlatform.class)
class WorkreportCrudFacadeTest {

  private static Logger LOGGER = LogManager.getLogger(WorkreportCrudFacadeTest.class);

  @Test
  public void detailTest() {

    final AccessRightsService ars = Mockito.mock(AccessRightsService.class);
    final SystemPriceSettingService spss = Mockito.mock(SystemPriceSettingService.class);
    final WorkreportActivityRepository wrar = Mockito.mock(WorkreportActivityRepository.class);
    final WorkreportRepository wrr = Mockito.mock(WorkreportRepository.class);
    final DomainObjectTools dot = Mockito.mock(DomainObjectTools.class);
    final ApplicationEventPublisher aep = Mockito.mock(ApplicationEventPublisher.class);

    Mockito.when(ars.hasEmployeeRightsToWorkReport(
        ArgumentMatchers.any(Employee.class), ArgumentMatchers.any(Workreport.class)
        )
    ).thenReturn(true);

    final WorkreportCrudFacade s = new WorkreportCrudFacade(ars, spss, wrar, wrr, dot, aep);

    final EmployeeId employeeId = new EmployeeId(154149756298300L);
    final WorkreportId workreportId = new WorkreportId(154149757395700L);

    final Workreport detail = s.detail(workreportId, employeeId);

    LOGGER.debug("Detail: {}", detail);

  }

}

调用测试方法的方法：

  public Workreport detail(final WorkreportId workreportId, final EmployeeId employeeId) {

    final Workreport workreport = domainObjectTools.getWorkreportOrThrowNotFoundException(workreportId);
    final Employee viewer = domainObjectTools.getEmployeeOrThrowNotFoundException(employeeId);

    boolean hasRights = accessRightsService.hasEmployeeRightsToWorkReport(viewer, workreport);

    LOGGER.debug("Has rights: {}", hasRights);

    if (!hasRights) {
      throw new ForbiddenException();
    }

    return workreport;

  }

但是当我在 WorkreportCrudFacade 实例上调用测试方法 hasEmployeeAccessToWorkReport 时，该方法没有正确存根（它应该 return true，但是 return s false).

我确定它会是一些细节，但我无法找出问题所在 - 可能是参数匹配器中的某些内容，但不确定。

我正在使用 Mockito 2.22.0。

引自ArgumentMatchers javadoc：

Since Mockito any(Class) and anyInt family matchers perform a type check, thus they won't match null arguments. Instead use the isNull matcher.

我认为这里发生了以下情况：您的 DomainObjectTools 是一个空模拟（未存根），因此它 returns null Workreport 和 null Employee。结果调用 accessRightsService.hasEmployeeRightsToWorkReport(null,null)。 null 值与 ArgumentMatchers.any(Class) 不匹配。

Mockito mock 没有正确匹配参数（？）
