Selenium2学习-007-WebUI自动化实战实例-005-解决 Firefox 版本不兼容：org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary

此文主要讲述 Java 运行 Selenium 脚本时，因 Friefox 浏览器版本与 selenium-server-standalone-x.xx.x.jar 不兼容引起的 org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary 报错解决方法。

希望能对初学 Selenium2 WebUI 自动化测试编程的亲们有所帮助。若有不足之处，敬请大神指正，不胜感激！

之前给朋友初步介绍了 Selenium 启动不同浏览器的脚本编写，对应源码亲们可参阅博文：WebUI自动化实战实例-003-三种浏览器（Chrome、Firefox、IE）启动脚本。今天，在朋友 PC 上运行时，提示如下的错误信息：

从信息中可看出，Selenium 无法启动 Friefox 浏览器而导致程序报错信息。解决步骤：

初始以为是因为 WebDriver 驱动的问题，更换后发现问题依然存在
查看其 Firefox 的版本为 35，觉得问题出在了 Firefox 版本与 selenium-server-standalone 版本不对应导致的，于是将 Firefox 版本降至 31，脚本运行通过；
将 Firefox 版本升级为 35，下载最新的 selenium-server-standalone-2.44.0.jar（下载地址：http://yunpan.cn/cyaZTHGtiav9Y 提取码 96a6）导入工程，脚本运行通过

至此，WebUI 自动化功能测试脚本第 004 篇-解决 Firefox 版本不兼容：org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary 顺利完结，希望此文能够给初学 Selenium 的您一份参考。

最后，非常感谢亲的驻足，希望此文能对亲有所帮助。热烈欢迎亲一起探讨，共同进步。非常感谢！ ^_^
