My question: Is it safe enough to use a method with a leading underscore?
Generally no. In this specific case you might be safe. However, if you
use _commit() in Django's standard TestCase you might make your
testing DB dirty and some other test could break because of that. This
kind of bug is horrible to debug.
Is there a better method?
Use TransactionTestCase
Thanks - much appreciated
Mike
which is meant for this kind of testing. In
TransactionTestCase you can safely use .commit() and .rollback(). The
cost is slower test execution. See: [https://docs.djangoproject.com/en/
dev/topics/testing/#django.test.TransactionTestCase].
