ADB错误代码

问题描述

我们有一个android设备，作为测试的一部分，我需要在目标设备上执行一个控制台测试应用程序.如果测试应用程序检测到错误，则返回-1.

We have an android device and as part of testing I need to excute a console test application on the target device. If the test application detects an error it returns -1.

我可以使用adb shell在目标上远程运行测试应用程序，但是我找不到找到返回代码的方法.我需要这样做，以便可以将其构建到自动化测试套件中.

I can use adb shell to run the test applications remotely on the target but I can't find a way of getting back the return code. I need this so I that I can build this into an automated test suite.

我可以尝试在控制台输出中添加一些失败文本，但这有点肮脏.有谁知道更优雅的解决方案?

I could try grepping the console output for some failure text but that is a bit grubby. Does anyone know of a more elegant solution?

推荐答案

这是获取退出代码的解决方法:adb shell'{您的命令在这里}>/dev/null 2>& 1;回显$?'

This is a workaround to get the exit code:adb shell '{your command here} > /dev/null 2>&1; echo $?'

这是Ruby中adb的包装:

This is a wrapper around adb in Ruby:

def adb(opt)
  input = "#{adb_command} #{opt[:command]} #{opt[:params]}"
  puts "Executing #{input}...\n"
  output = nil
  exit_code = 0

  def wait_for(secs)
    if secs
      begin
        Timeout::timeout(secs) { yield }
      rescue
        print 'execution expired'
      end
    else
      yield
    end
  end

  wait_for(opt[:timeout]) do
    case opt[:command]
    when :install, :push, :uninstall
      output, exit_code = `#{input}`, $?.to_i
    when :shell
      input = "#{adb_command} shell \"#{opt[:params]}; echo \\$?\""
      output = `#{input}`.split("\n")
      exit_code = output.pop.to_i
      output = output.join("\n")
    else
      raise 'Error: param command to adb not defined!'
    end
  end

  return if opt[:ignore_fail] and output =~ /#{opt[:ignore_fail]}/
  raise output unless exit_code == 0
end
