Question

我有一个使用Selenium和Python的自动化框架。为了运行Chrome浏览器，我将chrome驱动程序放在自动化框架的其中一个文件夹中。现在的问题是Chrome驱动程序在一段时间后得到了更新，我的脚本因此而开始失败，每当Google更新时，我都需要将更新的chrome驱动程序放在目录中。

我是否可以采用任何自动方式来解决此问题？

Answer 1

我遇到了同样的问题，所以我制作了一个硒脚本来自动从chromedrivers网站下载exe文件，并获取我所有的脚本以引用pythondriver中chromedriver.exe文件的当前位置。我在调度程序中与Google更新并行运行此脚本，因此当chrome更新时，驱动程序也会更新。

随意使用/重新组装它。

有没有办法在Test Automation Suite目录中自动更新chromedriver？
