Django: How to associate a user with a request factory
python,django,testing,django-testing,django-tests
I think that the RequestFactory and the client are two different ways of testing django views. The request that is returned from rf.post is meant to be passed directly to a view function. If you were to do that, i think you will find that, the user will be detected...
Write test for views containing os.remove in django
python,django,django-testing,django-tests
Yes. It's called mocking, and there is a Python library for it: mock. Mock is available in the standard library as unittest.mock for Python 3.3+, or standalone for earlier versions. So you would do something like this: from mock import patch ... @patch('mymodel_module.os.remove') def test_my_method(self, mocked_remove): call_my_model_method() self.assertTrue(mocked_remove.called) (where mymodel_module...
Unusual error in Django tests wrongly thinking instance doesn't exist
python,django,django-testing,django-tests
Wow, what a wild and crazy ride!! It turns out it was an issue in the RelatedListFilter with a custom queryset that was causing problems. The comments on this answer point out that: The filter lookups are getting cached in some way and field and field.rel objects will persist between...
Django Test Client not working with Database calls
Create a user in either the setUp() method of the TestCase, or add one in a fixture. Here's the setUp() version: class YourTestCase(TestCase): def setUp(self): self.user = User.objects.create( username='someuser', email='[email protected]', password='password' ) def test_your_code(self): # now you can look it up user = User.objects.get(username='someuser') self.assertEqual(user.email, '[email protected]') ...
How can i stop django to recreate test database
If you are just testing for development purposes, I'd recommend setting your testing database to use sqlite3, which will leverage an in-memory database by default and should speed up tests. I usually put this into local_settings which only gets executed for my dev environment... if 'test' in sys.argv: DATABASES['default'] =...
Why isn't Django creating blank a database during test?
django,django-models,django-testing
I'm going to take a stab and say that its because you are using nosetests instead of the Django test runner. Because you are using nosetests, Django's setup_test_environment isn't being called, which means the code doesn't know to use the test database correctly. Here are the relevant parts of the...
Logging in as an inactive user in a Django test
python,django,django-authentication,django-testing,django-1.7
I was able to solve this by setting the user to active right before doing the login: class BasicTest(TestCase): def setUp(self): u = InactiveUserFactory() u.set_password('test_pass') u.save() self.participant = ParticipantFactory(user=u) self.u = self.participant.user self.u.is_active = True self.u.save() login = self.client.login(username=self.u.username, password='test_pass') assert(login is True) self.u.is_active = False self.u.save() ...
django test client fails, but url works
django,unit-testing,django-testing
As you can see from the traceback, id passed in kwargs is evaluated to None. This is why it is not matching the usuarios/perfil/(?P<id>\\d+)/$ url pattern. In other words usuario_fake.pk value is None. UPD: the problem was actually in the template which the traceback was complaining about....

How to use verbosity level in your tests in Django
django,django-testing,django-unittest
You can use inspect module: from django.test import TestCase import inspect class MyTest(TestCase): def get_verbosity(self): for s in reversed(inspect.stack()): options = s[0].f_locals.get('options') if isinstance(options, dict): return int(options['verbosity']) return 1 def test_func(self): verbosity = self.get_verbosity() self.assertEqual(verbosity, 2) ...
Using coverage, how do I test this line?
The coverage report shows that the method is being called (line 80 is green). But it also shows that it was never defined (line 75 is red). This is a classic problem of starting coverage too late. The simplest way to fix this is to use coverage to run your...
Django - Writing Tests: Unit testing extra variables passed to generic views
django-class-based-views,django-testing
Okay, I finally figured this one out. Pretty simple: from django.test import TestCase from views import PurchaseIndex class IndexPageTest(TestCase): def test_current_purchase_index_displays_year(self): context = PurchaseIndex.list_year(self) self.assertEqual(2015, context) def test_current_shipments_included_in_current_purchase_index(self): context = PurchaseIndex.purchase_yrs(self) self.assertIn(2015, context) self.assertIn(2014, context) ...

You need to create a migration for the model WatchStock.
Django get_signed_cookie on manually signed cookie
python,django,cookies,django-rest-framework,django-testing
I have found my solution. It was rather straightforward actually. I tried to set my cookie on my request for the test, which made sense since the cookie should be sent in the request. A better way of testing it is to just GET a resource first (which sets te...
Django unit test to verify None fields on model

Try to save object to DB and test will fail: item = Item() item.save() Or shorter version with the same result: Item.objects.create() ...
Django test client does not handle exceptions?
python,django,http-status-code-500,django-testing
Django test client handles only some exceptions (see https://docs.djangoproject.com/en/1.7/topics/testing/tools/#exceptions). All the others are visible in the test and you can test them ;)
Fixture inheritance in django TestCase
When you override fixtures in a subclass, it replaces the fixtures, it doesn't extend them. You can either explicitly repeat the fixtures: class SpecificTest(BaseTest): fixtures = ('users.json', 'transactions.json',) or refer to BaseTest.fixtures in your subclass: class SpecificTest(BaseTest): fixtures = BaseTest.fixtures + ('transactions.json',) ...
Django Modular Testing
You can simplify and reduce the amount of code you have by using 2 libraries: WebTest and FactoryBoy. You won't need these Mixins. https://pypi.python.org/pypi/django-webtest https://github.com/rbarrois/factory_boy Do the change step by step: 1. Starts with WebTest so you can get rid of your login_ method (and you won't need to prepare...

How to use Django's assertJSONEqual to verify response of view returning JsonResponse
python,django,python-3.x,django-testing,jsonresponse
It looks like you're working with Python 3 so you'll need to turn response.content into a UTF-8 encoded string before passing it to self.assertJSONEqual: class AddItemToCollectionTest(TestCase): def test_success_when_not_added_before(self): response = self.client.post('/add-item-to-collection') self.assertEqual(response.status_code, 200) self.assertJSONEqual( str(response.content, encoding='utf8'), {'status': 'success'} ) If you want to simultaneously support both Python 2.7 and Python...
Is APITest with Query params different then just normal url?
django,unit-testing,django-rest-framework,django-testing
Try passing the query parameter as a data payload instead. Change the line in your test to: response = self.client.get('/api/titles-and-blurbs/', {'genre': 'horror'}) Django docs here on the different ways to pass query parameters in urls. Another person reported a similar issue with an empty QUERY_PARAMS while testing DRF (see here)....
How to test ModelForm save() method saves changes in model?
python,django,django-forms,django-testing,django-modeladmin
def test_form_saves_values_to_instance_user_on_save(self): """ test form saves name, surname, email values to corresponding User object when commiting form """ person = Person.objects.get(user__username='admin') personform = PersonForm(instance=person, data={'name': 'has_changed'}) if personform.is_valid(): person = personform.save() self.assertEquals(person.user.first_name, "has_changed") else: self.fail("personform not valid") I think you also need to exclude the user field from your form...
Integrity error when loading fixtures for Selenium testing in Django
django,selenium,fixtures,django-testing
After some more reading about how Django maintains its own models and such, it is my understanding that Django caches the contenttype, auth.Permission, etc and uses them in testing frameworks (I was using StaticLiveServerTestCase). This means that when I was loading my fixture, it was clashing with the data Django...
Authentication failed in Django test

Django testing ajax endpoint in view
python,ajax,django,unit-testing,django-testing
You could use something like django-casper: https://github.com/dobarkod/django-casper I haven't used it, but it appears to be a django-specific python library which interfaces with CasperJS and PhantomJS. PhantomJS is a web-kit based headless browser that gives a more light-weight alternative to browser automation with selenium....
Django test RequestFactory vs Client
django,unit-testing,django-views,django-rest-framework,django-testing
RequestFactory and Client have some very different use-cases. To put it in a single sentence: RequestFactory returns a request, while Client returns a response. The RequestFactory does what it says - it's a factory to create request objects. Nothing more, nothing less. The Client is used to fake a complete...
How to create table during Django tests with managed = False?
python,django,django-testing,django-1.7,django-migrations
I found a way. Modify the fixtures and add the SQL to generate the tables: #0001_initial.py (or followings) class Migration(migrations.Migration): operations = [ migrations.RunSQL("CREATE TABLE..."), ... ] I'm a "migrations newbie" so I don't know if this is the best option. But it works....
Django Testing: Does --keepdb reset changes made during tests?
django,django-testing,django-tests
If you're using Django's default TestCase, all tests are run in a transaction, which is rolled back when the tests finishes. If your database supports transactions, you won't have to clean up anything. If you're using Django's LiveServerTestCase or TransactionTestCase, all tables are truncated after each test, and the initial...
Users not created correctly in Django test case
django,django-models,django-testing
The user is not being created, because the setup method is not being run. It should be called setUp - note the upper-case U. See the Python documentation.

No module named .. while running Django tests with PyCharm
Ok, I found the problem. Problem was that PyCharm also have module named utils, and so the import was not using my module, but the PyCharm's one.
