FAIL: test_create_returns_new_list_object
self.fail()
AssertionError: None
FAILED (failures=1, errors=3)
We flesh it out:
lists/tests/test_models.py (ch19l039-2).
def
test_create_returns_new_list_object
(
self
):
returned
=
List
.
create_new
(
first_item_text
=
'new item text'
)
new_list
=
List
.
objects
.
first
()
self
.
assertEqual
(
returned
,
new_list
)
…
AssertionError: None != <List: List object>
And we add our return value:
lists/models.py (ch19l039-3).
@staticmethod
def
create_new
(
first_item_text
,
owner
=
None
):
list_
=
List
.
objects
.
create
(
owner
=
owner
)
Item
.
objects
.
create
(
text
=
first_item_text
,
list
=
list_
)
return
list_
And that gets us to a fully passing test suite:
$
python3 manage.py test lists
[...]
Ran 50 tests in 0.169s
OK
One More Test
That’s our code for saving list owners test-driven all the way down and working. But
our functional test isn’t passing quite yet:
$
python3 manage.py test functional_tests.test_my_lists
selenium.common.exceptions.NoSuchElementException: Message: 'Unable to locate
element: {"method":"link text","selector":"Reticulate splines"}' ; Stacktrace:
It’s because we have one last feature to implement, the
.name
attribute on list objects.
Again, we can grab the test and code from the last chapter:
lists/tests/test_models.py (ch19l040).
