问题描述

我是selenium webdriver的新手，并在Firefox 25.0中使用selenium-server-standalone-2.39.0.jar。

这是我的代码： 

package org.cost;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class First_Program {
    WebDriver driver;
    @BeforeTest
    public void beforetest(){

        driver= new FirefoxDriver();
        System.out.println("testing");
        driver.manage().window().maximize();

    }
    @Test
    public void test(){
        System.out.println("hello");
        driver.get("http://www.rediff.com/");
        driver.findElement(By.xpath("//*[@id='signin_info']/a[1]")).click();
        driver.findElement(By.xpath("//*[@id='c_uname']")).sendKeys("hello");


    }

}

当我运行此代码时，Firefox窗口启动，但一段时间后出现以下错误： 

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

请将您的硒独立jar文件也更新到最新的版本，甚至将其更新为firefox浏览器，然后尝试运行脚本。

Selenium独立的2.41x或2.42x firefox ...首先仅尝试使用您的版本，如果仍然遇到问题，请尝试升级到最新版本。

谢谢，

这是更改日志，可帮助您选择Firefox版本（适用于Java）

https://github.com/SeleniumHQ/selenium/blob/master/java/CHANGELOG

我希望对于最新的独立jar ，firefox 39不会有任何问题。 在我的工作空间中，我正在根据要求使用带有最新jar的FF 31。 我没有像这样的任何连接问题。

谢谢
