单元测试问题


package com.baosight.hbtrust.cs.ds.common;import java.math.BigDecimal;
import java.util.HashMap;
import java.util.Map;import com.baosight.hbtrust.cs.ds.biz.ICSDS0002Biz;

import com.baosight.iplat4j.core.spring.SpringApplicationContext;
import com.baosight.iplat4j.core.spring.SpringTestCase;
import com.baosight.ixbuscore.transport.webservice.DefaultWebServiceRequest;public class Test extends SpringTestCase {
/**
 * @param args
 */

private ICSDS0002Biz csds0002Biz; public void setup()  throws Exception{ csds0002Biz = (ICSDS0002Biz) SpringApplicationContext.getBean("csds0002Biz");//这一步报错，单元测试是不是不能加载spring配置文件
}
 
public void test001() throws  Exception{
setup();
Map map=new HashMap();
map.put("customerId", "P0000142");
map.put("customerType", "1");
map.put("partnerCreditLimit", new BigDecimal(100));
csds0002Biz.updateCreditLine(map);
}
}
谁帮我看一下，是写的不正确吗、DEBUG运行的test001()是一个web项目，TOmocat已经启动了，报错信息：java.lang.Exception: applicationContext未被初始化
