Openstf 只能识别75台可用设备,而 adb 能识别到120个。后来查到错误日志如下:

跟踪到一个 issue,问题应该是可用端口数不足,一个设备默认需要4个端口,stf 默认的端口数是300,解决办法是修改参数,或者修改代码中的默认值。

lib/cli/local/index.js
```js
    .option('provider-max-port', {
      describe: 'Highest port number for device workers to use.'
    , type: 'number'
    , default: 7900
    })
    .option('provider-min-port', {
      describe: 'Lowest port number for device workers to use.'
    , type: 'number'
    , default: 7400
    })
