mapping.json
Webview自动化测试，mapping.json 管理Chromedriver是怎么用的
appium提供了一个清单，里面列举了chromedriver的版本和chrome的版本对应关系。chromedriver会对chrome的版本有最低的要求。这个mapping文件就是制定了这个对应关系。
左侧是chromedriver的版本，右侧是支持的chrome的最低版本。这个文件除了官方维护了一个清单，也可以自己去编辑。如果在capability里自己指定了一份，那么appium就会根据指定文件判断应该使用哪个chromedriver的版本去自动化被测app内的webview组件版本

校长，web自动化测试，这三个Caps是不是都得配上
chromedriverExecutableDir，这个是存放所有chromedriver的路径
chromedriverChromeMappingFile，这个是各个版本的匹配映射关系
是这样么
看我讲课的时候代码例子吧。chromedriverExecutableDir可以测试webview，
chromedriverExecutableDir + chromedriverExecutable可以测试微信小程序
我其实想问，chromedriverExecutableDir，这个路径里，是需要我把所有版本的chromedriver都下载下来，保存到这个路径么？？
是的 可以不是所有 有需要的多个就行了
