采用Struts中的Mock方式模拟action和actionForm进行测试
基础类：STCRequestProcessor
作用：Ioc 将模拟的Action,ActionForm注入到struts-config.xml中的相应的action位置

Test类：
setUp()方法：
super.setUp();//调用mockStrutsTestCase中的setUp方法
File web = new File("E:/project/portal/WebContent");
this.setContextDirectory(web);//定位工程包的位置
setConfigFile("/WEB-INF/web.xml");//定位工程中的web.xml位置
setConfigFile("/WEB-INF/struts-config.xml");//定位工程中struts-config.xml位置
STCRequestProcessor.addMockActionForm("ser_wordForm", "test.sample.service.form.MockWordForm");//注入模拟的form
STCRequestProcessor.addMockAction("com.huawei.service.action.WordAction","test.sample.service.action.MockWordAction");//
注入模拟的action
setRequestPathInfo("/service/word");//定义struts-config.xml中的path名称
