Run the unit tests again, with
python3 manage.py test
:
ImportError: No module named 'superlists.views'
[...]
django.core.exceptions.ViewDoesNotExist: Could not import
superlists.views.home. Parent module superlists.views does not exist.
That’s progress! We’re no longer getting a 404; instead Django is complaining that the
dot-notation
superlists.views.home
doesn’t point to a real view. Let’s fix that, by
pointing it towards our placeholder
home_page
object, which is inside
lists
, not
superlists
:
superlists/urls.py.
urlpatterns
=
patterns
(
''
,
# Examples:
url
(
r'^$'
,
'lists.views.home_page'
,
name
=
'home'
),
And run the tests again:
django.core.exceptions.ViewDoesNotExist: Could not import
lists.views.home_page. View is not callable.
The unit tests have made the link between the URL
/
and the
home_page = None
in
lists/
views.py
, and are now complaining that
home_page
isn’t a callable; ie, it’s not a function.
Nowwe’ve got a justification for changing it frombeing
None
to being an actual function.
Every single code change is driven by the tests. Back in
lists/views.py
:
lists/views.py.
from
django.shortcuts
import
render
# Create your views here.
def
home_page
():
pass
And now?
$
python3 manage.py test
Creating test database for alias 'default'...
.
---------------------------------------------------------------------
Ran 1 test in 0.003s
OK
Destroying test database for alias 'default'...
Hooray! Our first ever unit test pass! That’s so momentous that I think it’s worthy of a
commit:
