1. “Dunder” is shorthand for double-underscore, so “dunderinit” means
__init__.py
.
If you get a message saying “Ran 0 tests”, you probably forgot to add the dunderinit—
it needs to be there or else the tests folder isn’t a valid Python module…

Nowwe turn
test_all.py
into two files, one called
test_views.py
, which only contains view
tests, and one called
test_models.py
:
$
git mv lists/tests/test_all.py lists/tests/test_views.py
$
cp lists/tests/test_views.py lists/tests/test_models.py
We strip
test_models.py
down to being just the one test—it means it needs far fewer
imports:
lists/tests/test_models.py (ch10l009).
from
django.test
import
TestCase
from
lists.models
import
Item
,
List
class
ListAndItemModelsTest
(
TestCase
):
[
...
]
Whereas
test_views.py
just loses one class:
lists/tests/test_views.py (ch10l010).
