[FR] Pytest-xdist should have its own remote agent

[Moved from pytest issue tracker, #2326 (https://github.com/pytest-dev/pytest/issues/2326)]

Hi There,

I started to used pytest not too far ago. And I found the xdist plugin. I would like to run test on a remote windows macine.

I saw in the documentation
(https://pypi.python.org/pypi/pytest-xdist/1.15.0)
the reference for socketserver.py

I checked the source, and found that it is mainly for unix/linux systems.
I tried it on windows 7, python 3.5. I sent only a print command to the remote, and it was printed successfully, but after that it wrote some errors. ...

Then I read the docs further and found that it says that init.py files should put next to my tests as the remoting handles them this way.

So I bet I would be able to rewrite the socketserver.py, but I think it would be better to create an authentic agent.

And of course I would install pytest on the remote as well (to have all the capabilities on the remote too)
As Python is installed on remote, I think there is no reason not install pytest as well.
(instead of socketserver.py third party stuff)

With this the xdist would be more complete.

Kind regards,
George

The issue names socketserver.py and the pytest-xdist documentation; start by reading the referenced remote-execution path and reproducing the reported Windows 7/Python 3.5 behavior. Clarify the agent protocol and platform requirements before changing code. Done means remote Windows execution works with pytest capabilities without the post-command errors described.
