Answer 1

One first advice would be to split the function in two parts, one that creates the queryset and one that manipulates the output of it. In this way testing the second part is straightforward.

For the database problem, I investigated if django uses sqlite-in-memory and I found out that recent version of django uses the sqlite -in-memory database, from The django unittest page:

When using the SQLite database engine the tests will by default use an in-memory database (i.e., the database will be created in memory, bypassing the filesystem entirely!).

Mocking the QuerySet object will not make you exercise its full logic.
