pytest-ssh is for ssh command run plugin of pytest.
It is basing on paramiko. The advantage of thhis tool is speed up pytest case development by assertion different situation in run_cmd(), like run_cmd(cmd,expect_ret=1) to assert the return is 1 or run_cmd(cmd,expect_not_kw='test1') to assert 'test1' not should not in output.
pip install pytest-sshdef test_ssh(ssh_get):
#create a SSH instance
session = ssh_get()
session.hostname = '127.0.0.1"
session.username = 'root'
#connet via default keyfile, you can also specify 'keyfile' location
session.connect()
cmd = 'uname -a'
#get status and output without any checking
status, output = session.run_cmd(cmd)
#check cmd return is 0 when run cmd
session.run_cmd(cmd, expect_ret=0)
#check cmd output include specified keywords
session.run_cmd('uname -r', expect_kw='4.18', msg='Check kernel version is 4.18')
#check cmd output not include specified keywords
session.run_cmd('uname -r', expect_not_kw='4.18', msg='Check kernel version is not 4.18')
#close session
session.close()
