简单的watir webdriver脚本在jenkins中失败

Question

我刚在本地安装了jenkins，我需要在jenkins中运行watir webdriver脚本，该脚本在命令提示符下运行成功。下面是简单的watir脚本。

require 'watir-webdriver'
b=Watir::Browser.new
b.goto "http://www.google.com"
b.text_field(:class => "gsfi").set "Avinash"
b.close

我将上面的代码保存到一个名为test.rb的文件中，当我在命令提示符上执行相同的代码时，它运行得很好。但是，我刚刚安装了Jenkins并创建了一个Freestyle项目。我将这个test.rb文件放在jenkins项目的工作区位置，在这个新创建的项目的configure部分中，在build部分下添加了"Execute Windows Batch Command“，并给出了ruby test.rb。现在我点击了我的项目的Build Now，我希望得到一个浏览器并执行我的Watir脚本。但是，我没有看到任何浏览器被触发，作业失败。下面是我所面临的错误

请让我知道我在这里错过了什么，这样我就可以在我的jenkins中点击build now并执行我的watir脚本后立即看到浏览器被触发。

99%的情况是由于浏览器和驱动程序不匹配造成的。可能是它没有在你的路径上找到正确的驱动程序，或者它加载的浏览器版本与其他版本不同。
