模拟paramiko.SSHClient().exec_command() [英] mock paramiko.SSHClient().exec_command()
问题描述
我需要通过ssh.exec_command()模拟执行某些远程命令 它将元组(stdin,stdout,stderr)作为paramiko.ChanelFile对象返回.
I need mock execution of some remote command via ssh.exec_command() It returns tuple (stdin, stdout, stderr) as paramiko.ChanelFile object.
因此,我将命令输出作为字符串(我想让exec_command()返回)以及如何使用输出字符串创建ChanelFile对象的问题.
So, I have output of command as string (which I want, exec_command() to return) and the question how to create ChanelFile object with my output string.
伪代码:
def send_command(self, cmd)
self.client.connect(hostname=self.host,
username=self.user,
password=self.password,
timeout=self.timeout)
stdin, stdout, stderr = self.client.exec_command(cmd)
return stdin, stdout, stderr
if __name__ == '__main__':
stdin, stdout, stderr = report.send_command('ls -la')
resp = stdout.read().strip()
所以我需要创建粗壮的东西才能在其上运行read()方法.
So I need create stout to be able run read() method on it.
推荐答案
请参见 https://stackoverflow.com/a/8168742/5512755 MagicMock也可以在这里工作.
See https://stackoverflow.com/a/8168742/5512755 A MagicMock works here too.
stdout = mock.MagicMock()
stdout.read().strip.return_value = "file1\nfile2\nfile3\n"
可以解决问题.
