使用JUnit测试ServiceLocator

我不知道如何处理错误消息.有没有人想建议我可以尝试的东西，希望能成功?ServiceLocator构造函数private ServiceLocator() throws UivException { try { ic = new InitialContext(); // System.out.println("Created the Initial Context"); cache = Collections.synchronizedMap(new HashMap()); } catch (NamingException ne) { throw new UivException(ErrorCode.SERVICE_LOCATOR_ERROR, 0, ne.getMessage()); } catch (NullPointerException e) { throw new UivException(ErrorCode.SERVICE_LOCATOR_ERROR, 0, e.getMessage()); }}解决方案那么，调用测试时，com.iplanet.ias.admin.common.ASException在类路径上吗?您是依靠应用服务器在其类路径中包含JDBC驱动程序的库，还是您自己进行部署?This is a follow up question to my previous question.I am trying to write test case for my ServiceLocator class but it gives me the following error:com/iplanet/ias/admin/common/ASExceptionjava.lang.NoClassDefFoundError: com/iplanet/ias/admin/common/ASException at java.lang.ClassLoader.defineClass1(Native Method)My test case:public void testServiceLocator () throws UivException, NamingException{ DataSource ds = ServiceLocator.getInstance().getDataSource("jdbc/RSRC/my/mydb"); //I have not put any assert statements because i know above line is failing}The above code fails on getInstance() method which looks like this:static public ServiceLocator getInstance() throws UivException { try { if (me == null) { synchronized(ServiceLocator.class) { me = new ServiceLocator(); } } return me; } catch (UivException e) { throw new UivException(ErrorCode.SERVICE_LOCATOR_ERROR, ErrorCode.SERVICE_LOCATOR_LOOKUP_ERROR, e.getMessage()); }}I know this ServiceLocator works fine because when I test my application from the front end there are no issues. Only reason I am writing this test case is because I want to test my DAO. And for me to test my DAO ServiceLocator has to work (from JUnit).I don't have a clue what to make of the error message. Does anyone want to suggest something I can try that will hopefully work?EDIT: ServiceLocator constructorprivate ServiceLocator() throws UivException { try { ic = new InitialContext(); // System.out.println("Created the Initial Context"); cache = Collections.synchronizedMap(new HashMap()); } catch (NamingException ne) { throw new UivException(ErrorCode.SERVICE_LOCATOR_ERROR, 0, ne.getMessage()); } catch (NullPointerException e) { throw new UivException(ErrorCode.SERVICE_LOCATOR_ERROR, 0, e.getMessage()); }} 解决方案 Well, is com.iplanet.ias.admin.common.ASException on the classpath when you invoke your tests?Are you relying on the app server to have the JDBC driver's libraries in it's classpath, or are you deploying it yourself? 这篇关于使用JUnit测试ServiceLocator的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 1403页，肝出来的..
