+该标签依赖的ApplicationContext对象，可以通过继承AbstractTransactionalJUnit4SpringContextTests获得,HttpServletRequest对象和pageContext对象可以通过Spring测试框架提供的模拟对象来模拟。
+测试代码如下:
+{{{ #!java
+@RunWith(SpringJUnit4ClassRunner.class)
+@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
+public class AdSumQueryTagTest extends AbstractTransactionalJUnit4SpringContextTests{
+        
+        @Test
+        public void doStartTag() throws Exception {
+                
+                AdSumQueryTag adSumQueryTag = new AdSumQueryTag();
+                adSumQueryTag.setApplicationContext(applicationContext);
+                adSumQueryTag.setItems("items");
+                
+                MockHttpServletRequest request = new MockHttpServletRequest();
+                
+                //模拟查询条件
+                request.addParameter("gid", "1");
+                request.addParameter("startdate", "2012-02-08");
+                request.addParameter("enddate", "2012-02-08");
+                
+                MockPageContext pageContext = new MockPageContext();
+                
+                adSumQueryTag.setHttpServletRequest(request);
+                adSumQueryTag.setPageContext(pageContext);
+                
+                adSumQueryTag.doStartTag();
