问答 正常运行能跑，后来直接把service 写成junit测试就一直不行，好像是外面的Dao注入失败，应该怎样写？求指导

按照上面的写的还是报错，import junit.framework.Assert;这个好像提示过时了。

package com.ifs.test;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

import junit.framework.Assert;

import org.junit.Test;
import org.nutz.dao.Dao;
import org.nutz.ioc.Ioc;

import org.nutz.trans.Trans;

import com.ifs.tenant.biz.AgentTranDelDao;
import com.ifs.tenant.entity.AgentTranDel;
import com.ifs.util.SeqDao;

@IocBean // 必须有
public class SimpleTest extends Assert {
    
    //private static final Log log = Logs.get();
    
    // 跟通常的@Inject完全一样.
    @Inject("refer:$ioc")
    protected Ioc ioc;
    
    @Inject
    protected Dao dao;
    @Inject
	protected AgentTranDelDao agentTranDelDao;
    @Inject
    protected SeqDao seqDao;
    
    @Test
    public void test_user_service_create_user() throws Exception {
    	AgentTranDel agentTranDel = new AgentTranDel();
    	Map<String, Object> hmap = new HashMap<String, Object>();
    	long id = seqDao.getSeqByTable("AgentTranDel");
		hmap.put("ORDER_NUM","6");

		    AgentTranDel agentTranDel2 = agentTranDelDao.saveAgentTranDel(agentTranDel);
			Trans.commit();
//			return agentTranDel2;
		} catch (Exception e) {
			e.printStackTrace();
		   Trans.rollback();
//		   return null;
		} finally {
		  Trans.close();
		}
    }
}

只要dao调用方法就进入这个异常
public InvocationTargetException(Throwable target) {
super((Throwable)null); // Disallow initCause
this.target = target;
}

要有RunWith,仔细看说明
