mock-ssh-server 0.1.0

Mock SSH server for testing purposes

mock-ssh-server is a context manager that implements an SSH server for testing purposes. It is built on top of paramiko, so it does not need OpenSSH binaries to be installed.

Sample usage

As a py.test fixture:

import os

from pytest import yield_fixture

from mockssh import Server


@yield_fixture(scope="function")
def server():
    users = {
        "sample-user": "/path/to/user-private-key,
    }
    with Server(users) as s:
        yield s


def test_ssh_session(server):
    for uid in server.users:
        with server.client(uid) as c:
            _, stdout, _ = c.exec_command("ls /")
            assert stdout.read()

def test_sftp_session(server):
    for uid in server.users:
        target_dir = tempfile.mkdtemp()
        target_fname = os.path.join(target_dir, "foo")
        assert not os.access(target_fname, os.F_OK)

        with server.client(uid) as c:
            sftp = c.open_sftp()
            sftp.put(__file__, target_fname, confirm=True)
            assert os.access(target_fname, os.F_OK)
