python - How fix error in unit test? | AssertionError -


i trying write unit-test create function in django project. first experience creating of unit-tests. why cant create new data? error understand there no articles in test database. did mistake?

tests.py:

class articleviewtestcase(testcase): def setup(self):     self.user = user.objects.create(         username='user',         email='user@gmail.com',         password='password'     )     self.client = client()  def test_article_create(self):     self.asserttrue(self.user)     self.client.login(username='user', password='password')     response = self.client.get('/article/create/')     self.assertequals(response.status_code, 200)      open('/home/nurzhan/downloads/planet.jpg', 'rb') image:         imagestringio = stringio(image.read()) <-- error here      response = self.client.post(         '/article/create/',         content_type='multipart/form-data',         data={             'head': 'test',             'opt_head': 'test',             'body': 'test',             'location': 1,             'public': true,             'idx': 0,             'image': (imagestringio, 'image.jpg')         },         follow=true     )     self.assertequal(response.status_code, 200)     self.assertequal(article.objects.all().count(), 1)

error:

traceback (most recent call last):   file "/home/nurzhan/ca/article/tests.py", line 26, in test_article_create     imagestringio = stringio(image.read()) typeerror: 'module' object not callable

you can override form_invalid , check data in test

class articlecreateview(createview):     # code here     def form_invalid(self, form):         data = {'status': false, 'errors': form.errors}         return jsonresponse(data, , status=500)

in test method:

with open('/home/nurzhan/downloads/planet.jpg', 'rb') image:     response = self.client.post('/article/create/',         data={             'head': 'test',             'opt_head': 'test',             'body': 'test',             'location': 1,             'public': true,             'idx': 0,             'image': image         },         follow=true, format='multipart'      )
