在Java中捕获异常

标签: java junit mockito

我正在为一个方法编写一个JUnit测试用例。我已经为它编写了积极的方案,但我不确定该方法是否正确编写或设计,因为我无法进入Catch块来捕获异常。我需要这个以获得更好的分支覆盖率。我无法使用Mockito,因为DaoExceptionChecked Exception

MUT

public List<IUiIntegrationDto> retrieveUiIntegrationReportData(List<String> agencyCode, Integer createdDays, String lob, String transactionStatus, 
        List<String> accounts, String sortKey, String sortOrder) throws ManagerException {
        List<IUiIntegrationDto> intgList = new ArrayList<IUiIntegrationDto>();

        try {
            intgList = getUiIntegrationDao().retrieveUiIntegrationReportData(agencyCode, createdDays, lob, transactionStatus, accounts);
            if (null != intgList) {

                ComparatorUtil.sortESignatureIntegrationFields(intgList, sortKey, sortOrder);
            }
        } catch (DaoException de) {
            String message = "Error retrieving ui integration report data";
            IExceptionHandlerResponse r = getExceptionHandler().handleData(de, ManagerException.class, message);
            if (r.isRethrow()) {
                ManagerException me = (ManagerException) r.getThrowable();
                throw me;
            }

        }
        return intgList;
    }

JUnit的

@Test(expected = DaoException.class)
public void testRetrieveUiIntegrationReportData_Exception() throws Exception {
    List<String> agencyCode = new ArrayList<>();
    agencyCode.add("044494");
    agencyCode.add("044400");

    Integer createdDays = 30;
    String lob = "01";
    String transactionStatus = "Completed";

    List<String> accounts = new ArrayList<>();
    accounts.add("CorpESignClientUser");
    accounts.add("GW_SYS_USER");

    String sortKey = "createdDate";
    String sortOrder = "desc";

    UiIntegrationManager integrationManager = new UiIntegrationManager();

    IUiIntegrationDao integrationDao = Mockito.mock(IUiIntegrationDao.class);

    IUiIntegrationDto uiIntegrationDto = new UiIntegrationDto();
    uiIntegrationDto.setClientUser("CorpESignClientUser");

    List<IUiIntegrationDto> integrationDto = new ArrayList<>();
    integrationDto.add(uiIntegrationDto);

    integrationManager.setUiIntegrationDao(integrationDao);

//  Mockito.doThrow(new DaoException("Exception thrown")).when(integrationDao.retrieveUiIntegrationReportData(agencyCode, createdDays, lob, transactionStatus, accounts));
//  Mockito.when(integrationDao.retrieveUiIntegrationReportData(agencyCode, createdDays, lob, transactionStatus, accounts)).thenReturn(integrationDto);

    integrationDto = integrationManager.retrieveUiIntegrationReportData(agencyCode, createdDays, lob, transactionStatus, accounts, sortKey, sortOrder);

    assertNotNull(integrationDto);
    assertFalse(agencyCode.isEmpty());
    assertEquals(2, agencyCode.size()); 
    assertNotNull(accounts);
    assertEquals("CorpESignClientUser", accounts.get(0));
    assertFalse(integrationDto instanceof ArrayList);
}

任何帮助将不胜感激

谢谢,

也许你可以转向PowerMocking方面,在静态调用中“工作”。

我在这里的通常建议:如果某些静态电话让你讨厌;然后摆脱它。

只需创建一个表示所需功能的界面;然后创建一个执行静态调用的简单实现(在生产环境中使用)。在测试环境中,使用依赖注入。含义:您创建该新接口的模拟实例;然后你把它交给你的班级。

就是这样。突然之间你只需要EasyMock,来模拟一个常见的花园非静态方法调用。

猜猜:这也改善了你的设计;因为它允许您将客户端代码与包含该静态方法的类完全分离!
