How to pass a form object in a request object in Django unit test?

Question

Suppose I have an unit test which tests a view. That view requires a form to do some processing. My unit test looks like this:

class ViewTests(TestCase):
def setUp(self):
    self.factory = RequestFactory()

def test_login_view_post(self):
    # require form object to pass it in post function
    response = self.client.post(reverse('login'))
    self.assertContains(response, "Your username and password didn't match", status_code=200)

Can someone tell me that how can I pass the form object in the post function?

Thanks.

You don't actually pass the form object in the post, you pass the form data as if the form was being submitted (which is what you are simulating)

post_data = {
    "username": "foo",
    "password": "bar"
}
response = self.client.post(reverse('login'), data=post_data)

Or you can simply include the form in another test and instantiate it with data to test its validity.

def test_form(self):
    data = {
        "username": "foo",
        "password": "bar"
    }
    form = LoginForm(data)
    self.assertFalse(form.is_valid())
