Hello,
I am now trying to write test cases for my project, but I find some
problems.
1.
class FirstTest(TestCase):
@classmethod
def setUpTestData(cls):
User.objects.create(username = 'johndoe', password =
'goodtobehere123')
...
def test_case_one(self):
user = User.objects.get(pk=1)
# some assertions here
...
class SecondTest(TestCase):
@classmethod
def setUpTestData(cls):
User.objects.create(username = 'janedoe', password =
'nicetobethere456')
def test_case_one(self):
user = User.objects.get(pk=1)
# some assertions here
...
If I run all the tests together, I can pass the FirstTest while getting
error of "django.contrib.auth.models.DoesNotExist: User matching query does
not exist." on the SecondTest.
If I run two test cases separately, all tests are passed.
Then solved it by changing it into this:
class FirstTest(TestCase):
@classmethod
def setUpTestData(cls):
cls.user = User.objects.create(username = 'johndoe', password =
'goodtobehere123')
...
def test_case_one(self):
self.assertEqual(self.user.somefunc(), something)
# some assertions here
...
class SecondTest(TestCase):
@classmethod
def setUpTestData(cls):
cls.user = User.objects.create(username = 'janedoe', password =
'nicetobethere456')
...
def test_case_one(self):
self.assertEqual(self.user.somefunc(), something)
# some assertions here
...
However I don't know why.....?????
2.
class ViewTest(TestCase):
@classmethod
def setUpTestData(cls):
cls.user = User.objects.create(username = 'johndoe', password =
'goodtobehere123')
...
def setUp(self):
self.item = Item.objects.create(
category = 1,
item_content = 'content content',
)
def test_item_update(self):
# the view will update the item and return HTTP status code 200.
# if the item is not exist, raise Http404
self.c = Client()
resp = self.c.post(
reverse('update_item', kwargs={"pk":self.item.pk}),
data = {
"category": 2,
"content": "item content",
}
)
self.assertEqual(resp.status_code, 200)
self.assertEqual(self.item.category, 2)
def test_item_delete(self):
# the view will delete the item and return HTTP status code 200.
# if the item is not exist, raise Http404
self.c = Client()
resp = self.c.post(
reverse('delete_item'),
data = {
"pk": self.item.pk
}
)
self.assertEqual(resp.status_code, 200)
I got " AssertionError: 1 != 2 ". for test_item_update()
and "AssertionError: 404 != 200". for test_item_delete()
I think it is reasonable but obviously I misunderstand something.
Thank you. I will be very happy if you want to help me >___<
