How can I call a custom Django manage.py command directly from a test driver?

Question

I want to write a unit test for a Django manage.py command that does a backend operation on a database table. How would I invoke the management command directly from code?

Answer 1

the following code:

from django.core.management import call_command
call_command('collectstatic', verbosity=3, interactive=False)
call_command('migrate', 'myapp', verbosity=3, interactive=False)

...is equal to the following commands typed in terminal:

$ ./manage.py collectstatic --noinput -v 3
$ ./manage.py migrate myapp --noinput -v 3

See running management commands from django docs.
