博客讲述了在进行Web自动化测试时遇到的错误'unknown error: call function result missing 'value''，问题根源在于Chrome浏览器自动更新后与当前WebDriver版本不兼容。解决方案是下载与Chrome版本匹配的WebDriver，可以从官方网站或淘宝npm镜像获取，并参考notes.txt文件确认版本对应关系。

平时工作中用web 自动化做点事情，结果之前写好的脚本运行一直正常的，某一天莫名其妙不行了，一直报下面这个错。

unknown error: call function result missing 'value'

后来发现是chrome自动更新版本后和原来的webdriver 的版本不匹配了。重新下一个匹配的webdriver 就可以了。

可以从以下网站下载到 chrom webdriver 网站。

http://chromedriver.storage.googleapis.com/

http://npm.taobao.org/mirrors/chromedriver/

在每个版本中都有一个notes.txt, 文件里会写明webdriver 和chrome 对应的版本。
