(1)环境设置：导入HttpUnit

　　(2)开始实践，写一个测试接口，起名为LoginTestInf：

/**
 *测试用例编号 : 0001
 *测试用例名称 : HttpUnit 登陆验证测试用例
 *测试目标 : 验证用户登陆是否成功
 *测试过程 :
 *1、输入登陆地址的页面地址，验证该页面是否可被正常访问。
 *2、验证被访问的页面是否是登陆页面。
 *3、输入非法用户名、密码，验证登陆失败。
 *4、输入合法用户名、密码，验证登陆成功。
 */    
public interface LoginTestInf {
    public void testValidPage() throws Exception;
    public void testIsLoginPage() throws Exception;
    public void testBadLogin() throws Exception;
    public void testGoodLogin() throws Exception;
}

　　(3)实现一个Junit TestCase 同时 implements LoginTestInf 接口：

 * Window - Preferences - Java - Code Style - Code Templates
 */
package org.apollo.test.util;

import java.net.URL;
import junit.framework.TestCase;
import junit.framework.TestSuite;
import junit.textui.TestRunner;
 
import com.meterware.httpunit.WebConversation;
import com.meterware.httpunit.WebRequest;
import com.meterware.httpunit.WebResponse;
import com.meterware.httpunit.WebForm;
import com.meterware.httpunit.GetMethodWebRequest;

import org.apollo.test.util.LoginTestInf;

/**

 */
public class LoginTest extends TestCase implements LoginTestInf {

 private String username = "suibian";
 private String password = "suibian";
 
    private WebConversation browser;

    private WebRequest requestLogin;
    private WebResponse responseIndex;

    private String urlLogin = "登陆界面网址";
 /*

  */
 protected void setUp() throws Exception {
        browser =  new WebConversation();
        requestIndex = new GetMethodWebRequest(urlSystem);
        responseIndex  = browser.getResponse(requestIndex);
        requestLogin = new GetMethodWebRequest(urlLogin);

 }
 
    //输入登陆地址的页面地址，验证该页面是否可被正常访问
    public void testValidPage() throws Exception{

    }

           String currentUrlStr = currentUrl.getProtocol() + "://" +currentUrl.getHost() + currentUrl.getPath();
           assertEquals("登陆页面不是zsonline首页!" ，currentUrlStr，urlLogin);
    }
 
    //输入非法用户名、密码，验证登陆失败
    public void testBadLogin() throws Exception{
          WebForm form = responseLogin.getForms()[0];
          form.setParameter("username"，"badname");

          assertTrue("用户名不存在，请确认用户名输入是否完全正确(区分大小写)！"，
                  responseLogin.getText().indexOf("用户名不存在，请确认用户名输入是否完全正确(区分大小写)！") != -1);
    }
 
   //输入合法用户名、密码，验证登陆成功
    public void testGoodLogin() throws Exception{
          WebForm form = responseLogin.getForms()[0];
          form.setParameter("username"，username);
          form.setParameter("password"，password);//此处需要填写真实密码
          requestLogin = form.getRequest();
          responseLogin =  browser.getResponse(requestLogin);
          assertTrue("转到'zsonline'【suibian】用户首页失败！"，responseLogin.getText().indexOf("用户测试用户_zsonline，您好！") != -1);   
    }
 
    public static TestSuite suite(){
        return new TestSuite(LoginTest.class);
      }
      public static void main(String args[]){
        TestRunner.run(suite());
      }
}
