lint                 Run code formatters and linter
fix-code-style       Fix code formatting
tox-listenvs         List all tox test environments
tox                  Run pytest via tox with all environments
tox-py36             Run pytest via tox with *python v3.6*
tox-py37             Run pytest via tox with *python v3.7*
tox-py38             Run pytest via tox with *python v3.8*

You can start the test project with the Django developing server, e.g.:

~/bx_py_utils$ make start-dev-server

This is a own manage command, that will create migrations files from our test app, migrate, collectstatic and create a super user if no user exists ;)

If you like to start from stretch, just delete related test project files with:

~/bx_py_utils$ make clean

...and start the test server again ;)
