pytest-sftpserver is a plugin for pytest_ that provides a local SFTP-Server fixture_.

The SFTP-Server provided by this fixture serves content not from files but directly from Python objects.

Quickstart

Assume you want to test a function that downloads a file from an SFTP-Server:

.. code-block:: python

from contextlib import closing
import paramiko
def get_sftp_file(host, port, username, password, path):
    with closing(paramiko.Transport((host, port))) as transport:
        transport.connect(username=username, password=password)
        with closing(paramiko.SFTPClient.from_transport(transport)) as sftpclient:
            with sftpclient.open(path, "r") as sftp_file:
                return sftp_file.read()

This plugin allows to test such functions without having to spin up an external SFTP-Server by providing a pytest fixture_ called sftpserver. You use it simply by adding a parameter named sftpserver to your test function:

.. code-block:: python

def test_sftp_fetch(sftpserver):
    with sftpserver.serve_content({'a_dir': {'somefile.txt': "File content"}}):
        assert get_sftp_file(sftpserver.host, sftpserver.port, "user",
                             "pw", "/a_dir/somefile.txt") == "File content"

As can be seen from this example sftpserver serves content directly from python objects instead of files.

Inspiration

The implementation and idea for this plugin is in part based upon:

• pytest-localserver_
• sftpserver_
• The Twisted Conch in 60 Seconds_ series (although I ended up not using twisted, this was very helpful understanding SFTP internals)
