Is it good practice to do integration testing on Django's admin section?
I know StackOverflow discourages 'opinion-based' questions, but this seems very basic and I'm surprised by the lack of info on it. Normally I would think of some kind of Selenium test for any UX as mandatory, but the Django testing docs don't mention anything of the sort, and Googling for 'Django admin integration test' and similar isn't highlighting anything about the admin section. Do people just tend to unit test the admin.py subclasses and leave it at that, assuming the rest is covered by the framework? -
