使用cactus进行单元测试的方法

 一、在web.xml中配置返调servlet

    <servlet>
        <servlet-name>ServletRedirector</servlet-name>
        <servlet-class>
            org.apache.cactus.server.ServletTestRedirector
        </servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>ServletRedirector</servlet-name>
        <url-pattern>/ServletRedirector</url-pattern>
    </servlet-mapping>

二、在classes目录下配置cactus.properties配置文件

cactus.contextURL=http://localhost:8080/school   测试的URL
cactus.servletRedirectorName=ServletRedirector   反调Servlet名称

三、拷贝cactus库到lib目录下
四、启动WEB Server
五、写单元测试程序

package org.school.test;


//import java.util.Random;

import junit.framework.Test;
import junit.framework.TestSuite;
import servletunit.struts.CactusStrutsTestCase;

import org.apache.cactus.WebRequest;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;


public class testUserAction extends CactusStrutsTestCase ...{
    protected final Log log = LogFactory.getLog(getClass());

    
    public testUserAction(String arg)...{
        super(arg);
    }
    
    public void beginRegister(WebRequest theRequest) ...{
//        theRequest.addHeader("METHOD", "POST");
//        theRequest.addParameter("param", "value", WebRequest.POST_METHOD);
//        Random rand=new Random();
        //加载post 数量
        theRequest.addParameter("username", "jingmin", WebRequest.POST_METHOD);
        theRequest.addParameter("password", "vkbje76", WebRequest.POST_METHOD);
        theRequest.addParameter("repassword", "vkbje76", WebRequest.POST_METHOD);
        theRequest.addParameter("email", "[e-mail]", WebRequest.POST_METHOD);
    }


    public void testRegister() ...{
        setRequestPathInfo("/register");
        actionPerform();
        verifyNoActionErrors();
    }
    
    public void testLogin() ...{
        setRequestPathInfo("/login");
        addRequestParameter("username", "jingmin");
        addRequestParameter("password", "vkbje76");
        actionPerform();
//        Enumeration names=request.getAttributeNames();
//        while(names.hasMoreElements()){
//            String name=(String)names.nextElement();
//            log.error(name);
//        }
//        log.error(request.getAttribute("org.apache.struts.action.MESSAGE"));
        verifyNoActionErrors();
    }
    
    public static Test suite()...{
        TestSuite suite=new TestSuite();
//        

        suite.addTest(new testUserAction("testRegister"));
        suite.addTest(new testUserAction("testLogin"));
        suite.addTest(new testUtil("testMD5"));
        return suite;
    }
    
    @Override
    protected void setUp() throws Exception ...{
        super.setUp();
    }

    @Override
    protected void tearDown() throws Exception ...{
        super.tearDown();
    }

}

五、进行单元测试
以上方法可以对struts+spring+Hibernate进行测试，还可以配置文件在WEB Servlet直接进行测试
