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 ;)
