使用python自动化android CTS

Question

我试图在Ubuntu上用python & monkeyrunner自动化整个CTS的设置和执行，大部分都进行得很好。作为最后一步，我尝试执行以下python命令以在特定设备上启动CTS：

cts_tradefed_script = "./android-cts/tools/cts-tradefed"
process = subprocess.Popen([cts_tradefed_script, "run", "cts", "-s", '"' + serialno + '"', "--plan", "CTS"], shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

这相当于：

./android-cts/tools/cts-tradefed run cts -s "R32CB054TSZ" --plan CTS

在命令行中，我得到：

Android CTS 4.2_r4
No commands for non-interactive mode; exiting.
06-17 17:32:32 I/: Detected new device R32CB054TSZ
Saved log to /tmp/tradefed_global_log_9173619073367947049.txt
06-17 17:32:32 I/CommandScheduler: All done

CTS测试不会执行。有没有我忘了的命令，或者这是不可能用Python实现的？

Answer 1

cts_tradefed_script = "./android-cts/tools/cts-tradefed"
process = subprocess.Popen([cts_tradefed_script + " " + serialno], shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

编辑:脚本不是必需的。只需将所有内容作为连接字符串输入即可。

非交互式的问题是您不能运行超过一个命令，所以您应该尝试在交互式模式下运行。

要在交互模式下运行，这是一种方法：

#pip install paramiko
import paramiko
import time

def run_remote_command(channel, command):
  channel.send(command)
  whole_output = ""
  while True:
    if channel.recv_ready():
      output = channel.recv(1024)
      whole_output+=output
    else:
      time.sleep(0.5)
      if not(channel.recv_ready()):
        return whole_output

server ="fill you own here"
username = "fill you own here"
password = "fill you own here"
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(server, 22 ,username, password)
channel =ssh.get_transport().open_session()
channel.get_pty()
channel.invoke_shell()


run_1 =run_remote_command(channel,"~/android/out/host/linux-x86/cts/android-cts/tools/cts-tradefed list devices" + "\n")
print run_1

run_2 =run_remote_command(channel,"run cts" + "\n")
print run_2

run_3 =run_remote_command(channel,"l i" + "\n")
print run_3
