用Selenium登录问题

我正在尝试使用用户名“username”和密码“password”登录到我们的生产站点，例如“http://site.com”。当我执行测试时，它会到达站点打开的阶段，但它不会输入用户名和密码。代码如下：用Selenium登录问题

<form name="login" method="post" action="j_security_check"> 
             <table> 
              <tbody> 
               <tr> 
                <td> 
                 <label style="color: gray; left: 0px; top: 48px;"> 
                  Username: 
                 </label> 
                </td> 
                <td> 
                 <input type="text" mandatory="true" value="" name="j_username" tabindex="1"> 
                </td> 
               </tr> 
               <tr> 
                <td> 
                 <label style="color: gray; left: 0px; top: 96px;"> 
                  Password: 
                 </label> 
                </td> 
                <td> 
                 <input type="password" mandatory="true" name="j_password" value="" tabindex="2"> 
                </td> 
               </tr> 
               <tr> 
                <td colspan="2"> 
                 <input type="submit" value="Login" name="login" tabindex="3" style="width: 87px;height:30px"> 
                </td> 
               </tr>

浏览器显示什么？您是否尝试过使用Eclipse调试测试？ – artbristol

浏览器无法启动。它卡在这一行：driver = new FirefoxDriver（）。我做了一个netstat | grep 7055，但是，这并没有显示任何正在监听端口7055的进程。所以，我想知道它为什么会这样做：（ – crazyaboutliv

当测试失败时，你会得到什么异常？ –
