Exercism.io automation with pytest and version control

Question

CI newbie here. I'm currently working on the python track for Exercism.io. I'm looking for a way to automate the process of running tests from pytest, committing and pushing to github, and finally submitting to exercism if all tests pass. I've implemented a pre-commit hook to invoke tests on commit but I'm not sure how to pass the filename back to exercism for submission. Any help is greatly appreciated!

I put together a solution for anyone else looking for a similar workflow. It utilizes a python script in the root directory and handles the git commands via subprocess. It also supports autocomplete for the file directory (based on this gist). This script assumes you've already initialized the git repo and setup your remote repo as well.

#!/usr/bin/env python

import pytest
import subprocess
import readline
import glob

class tabCompleter(object):
    """ 
    A tab completer that can complete filepaths from the filesystem.

    Partially taken from:
    http://stackoverflow.com/questions/5637124/tab-completion-in-pythons-raw-input
    """

    def pathCompleter(self,text,state):
        """ 
        This is the tab completer for systems paths.
        Only tested on *nix systems
        """
        return [x for x in glob.glob(text+'*')][state]

if __name__=="__main__":
    # Take user input for commit message
    commit_msg = raw_input('Enter the commit message: ')

    t = tabCompleter()

    readline.set_completer_delims('\t')

    # Necessary for MacOS, Linux uses tab: complete syntax
    if 'libedit' in readline.__doc__:
        readline.parse_and_bind("bind ^I rl_complete")
    else:
        readline.parse_and_bind("tab: complete")

    #Use the new pathCompleter
    readline.set_completer(t.pathCompleter)

    #Take user input for exercise file for submission
    ans = raw_input("Select the file to submit to Exercism: ")

    if pytest.main([]) == 0:
        """
        If all tests pass: 
        add files to index,
        commit locally,
        submit to exercism.io,
        then finally push to remote repo.
        """
        subprocess.call(["git","add","."])
        subprocess.call(["git","commit","-m", commit_msg])
        subprocess.call(["exercism","submit",ans])
        subprocess.call(["git","push","origin","master"])
