Jms 在activemq上调试单元测试时获取nullpointer异常
我有下面的单元测试，它给了我一个空指针异常。调试器将转到创建连接工厂的行后面的finally块。以下是测试：Jms 在activemq上调试单元测试时获取nullpointer异常,jms,activemq,junit4,Jms,Activemq,Junit4,我有下面的单元测试，它给了我一个空指针异常。调试器将转到创建连接工厂的行后面的finally块。以下是测试： @Test public void receiveMessage() throws Exception { MessageConsumer consumer = null; ConnectionFactory connectionFactory = null; Connection connection = null

在单元测试中，不应使用实际连接，即在单元测试用例中尝试连接到BrokerURL，这不是单元测试的目的 在这种情况下，需要使用Easymock+Powermock或Mockito等库模拟外部连接 关于空指针异常，您的代理启动了吗？用户名和密码正确，请检查这些
