Experimenting with Duplicate Item Validation at the Views Layer

Let’s try running our FT, just to see where we are:

selenium.common.exceptions.NoSuchElementException: Message: 'Unable to locate element: {"method":"id","selector":"id_list_table"}' ; Stacktrace:

In case you didn’t see it as it flew past, the site is 500ing.[16] A quick unit test at the view level ought to clear this up:

lists/tests/test_views.py (ch12l014).

class ListViewTest(TestCase): [...] def test_for_invalid_input_shows_error_on_page(self): [...] def test_duplicate_item_validation_errors_end_up_on_lists_page(self): list1 = List.objects.create() item1 = Item.objects.create(list=list1, text='textey') response = self.client.post( '/lists/%d/' % (list1.id,), data={'text': 'textey'} ) expected_error = escape("You've already got this in your list") self.assertContains(response, expected_error) self.assertTemplateUsed(response, 'list.html') self.assertEqual(Item.objects.all().count(), 1)
