我在Robot Framework测试中遇到ssh隧道问题。我用sshpass命令设置变量$ {command}。之后，我尝试通过Run Process或Run或Start Process在环境中运行此命令。
${command} Set Variable sshpass -p password ssh -q -L 1234:192.168.253.18:22 192.168.255.1 -N &
${process} Run Process ${command} cwd=${CURDIR} shell=True on_timeout=continue timeout=5
#${process} Start Process ${command} cwd=${CURDIR} shell=True stderr=${CURDIR}/stderr.txt stdout=${CURDIR}/stdout.txt
#${process} Run ${command}
如果我手动运行此命令，一切正常 - 创建ssh隧道，进程正在运行。
abc@abc:~/robot/EDA$ sshpass -p password ssh -q -L 1234:192.168.253.18:22 192.168.255.1 -N &
[1] 23634
abc@abc:~/robot/EDA$
如果我通过Run运行此关键字测试正在等待进程完成，但它等待无限。

如果我通过Start Process运行：

stdout.txt和stderr.txt为空。流程没有创建。
如果我通过Run：
运行此命令20180525 22:02:12.226 - INFO - +---- START KW: OperatingSystem.Run [ ${command} ]
20180525 22:02:12.230 - INFO - Running command 'sshpass -p password ssh -q -L 1234:192.168.253.18:22 192.168.255.1 -N 2>&1 &'.
并且测试也在等到无限。
有人可以帮我解决这个问题吗？
