我在使用嘲笑2.23.4，junit4和springrunner进行测试时遇到困难。即使代码看起来对我来说很好，我仍然会收到InvalidUseOfmatchersException。我不确定我到底缺少什么。任何提示对我都会非常有帮助。我将在下面发布代码。

    @RunWith(SpringRunner.class)
    public class FiscalClosingServiceImplTest {
        @InjectMocks
        private FiscalClosingServiceImpl fiscalClosingServiceImpl;
        @Mock
        private IDataBeanmanager dataBeanmanager;
        @Mock
        private IFiscalClosingPopulator fiscalClosingPopulator;
        @Mock
        private DataBean dataBean;
        @Test
        public void test_getFiscalClosingListByNodeIdAndSiteId_WhenListNotEmpty() throws ServiceException {
            //Arrange
            List<DataBean> dataBeansResult = new ArrayList<DataBean>();
            dataBeansResult.add(dataBean);
            when(dataBeanmanager.listBeansByAttributeValue(anyString(),anyString(),anyString())).thenReturn(dataBeansResult);
            String siteId = "siteId";
            FiscalClosing fiscalClosingTest = new FiscalClosing();
            fiscalClosingTest.setSiteId(siteId); 
 when(fiscalClosingPopulator.convertBeanToFiscalClosing(any(DataBean.class))).thenReturn(fiscalClosingTest);

        //act
        List<FiscalClosing> result = fiscalClosingServiceImpl.getFiscalClosingListByNodeIdAndSiteId(anyString(),eq(siteId));

        //Assert
        assertEquals(result.get(0).getSiteId(),fiscalClosingTest.getSiteId());
    }
}

下面要测试的方法：

@Override
    public List<FiscalClosing> getFiscalClosingListByNodeIdAndSiteId(final String nodeId,final String siteId)
            throws ServiceException {
        log.debug("Retrieving FiscalClosing by transactionLastUpdatedDateTime");
        List<FiscalClosing> fiscalClosingList = new ArrayList<FiscalClosing>();

        List<DataBean> dataBeans = dataBeanmanager.listBeansByAttributeValue(
                EntityConstant.getconstant(CONSTANTS.FISCAL_CLOSING_ID),EntityConstant.getconstant(CONSTANTS.FISCAL_CLOSING_NODE_ID_ID),nodeId,"");

        if(dataBeans.isEmpty()) {
            return fiscalClosingList; 
        }

        for(DataBean dataBean : dataBeans) {
            FiscalClosing fiscalClosing = fiscalClosingPopulator.convertBeanToFiscalClosing(dataBean);
            fiscalClosingList.add(fiscalClosing);
        }

        return fiscalClosingList.stream().filter(item -> item.getSiteId().equals(siteId)).collect(Collectors.toList());
    }
