python+monkey+ 监控 crash,性能统计

之前写过monkey方面的测试,这次刚好有项目用到,并且需要监控性能信息,所以重构了一次

monkey 压力测试android

  • python3
  • 统计性能信息cpu,men,fps,battery,flow
  • 支持wifi,gprs统计
  • 统计crash信息
  • 查看源码

monkey.ini 配置文件


cmd=adb shell monkey -p com.jianshu.haruki --throttle 500 --ignore-timeouts --ignore-crashes --monitor-native-crashes -v -v -v 200 >
package_name=com.jianshu.haruki
activity = com.baiji.jianshu.account.SplashScreenActivity
net = wifi
  • throttle 每次事件等待500毫秒
  • net 支持gprs和wifi

2.0 版本更新

  • 优化了统计性能数据的代码
  • 支持多设备
  • 用了持久化记录信息,删除全局变量统计性能信息
