Just git clone and apistar run !
Have you thought of writing a cookiecutter template for a project starter?
I have no idea how to convert it into a cookiecutter, if you know how, feel free to send Pull Requests.
Mainly without loosing the ability to just git clone it and still works Ok.
I always use extra features of postgresql (and I believe many do too) so I can’t use sqlite for testing.
Don’t you do the same ?
Peewee has utils for that: http://docs.peewee-orm.com/en/latest/peewee/playhouse.html#test_database
