- 环境：macos
- 移动端型号：VIVO X30
- 移动端系统：android 10
- 问题复述：appium测试微信小程序切换context时，频繁出现chrome not reachable, 频率1/2左右。
- 开发语言：java
代码如下

capabilities.setBrowserName("");//初始化会默认将chrome浏览器打开，需要将Browser置为空
capabilities.setCapability("unicodeKeyboard", true);//使用unicode输入法
capabilities.setCapability("resetKeyboard", true);//重置输入法到初始状态
capabilities.setCapability("sessionOverride", true);// 每次启动时覆盖session，否则第二次后运行会报错不能新建session
capabilities.setBrowserName("");
capabilities.setCapability("newCommandTimeout", "6000");
//第三步:设置adb proxy
//通过自己的adb代理修复chromedriver的bug并解决@xweb_devtools_remote的问题
