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...
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'] =...
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',) ...
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)....
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...

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....
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 ;)
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 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...
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...
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...

Django - Writing Tests: Unit testing extra variables passed to generic views

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) ...
Django testing wastes too much time on test database creating

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]') ...
Django testing ajax endpoint in view

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....
How to test ModelForm save() method saves changes in model?

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...

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.
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 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...
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.
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...
How to create table during Django tests with managed = False?

Logging in as an inactive user in a Django test

Django: How to associate a user with a request factory
python,django,testing,django-testing,django-tests
