Download and start a redis server within your python project with nox.

noxfile.py

import nox
from pathlib import Path

PROJECT_ROOT_DIRECTORY = Path(__file__).parent
REDIS_DIRECTORY = PROJECT_ROOT_DIRECTORY / "redis-stable"
REDIS_COMPRESSED_FILE_NAME = "redis-stable.tar.gz"
REDIS_DOWNLOAD_URL = "http://download.redis.io/" + REDIS_COMPRESSED_FILE_NAME
REDIS_SERVER_LOCATION = REDIS_DIRECTORY / "src" / "redis-server"


@nox.session(python=False)
def redis(session):
    """

    """
    if not REDIS_SERVER_LOCATION.exists():
        session.run("wget", "--verbose", "--no-clobber", REDIS_DOWNLOAD_URL, external=True)
        session.run("tar", "-xzf", REDIS_COMPRESSED_FILE_NAME, external=True)
        session.run("rm", REDIS_COMPRESSED_FILE_NAME, external=True)
        session.cd(REDIS_DIRECTORY)
        session.run("make", external=True)

    assert REDIS_SERVER_LOCATION.exists(), "Something went wrong..."

    if session.posargs[0] == "runserver":
        session.run(str(REDIS_SERVER_LOCATION))
