Django’s test assertions have `assertContains` and `assertNotContains`
which are HTML-aware ways to check what’s inside a response, similar to
Python’s `assertIn` and `assertNotIn`. Django also offers `assertInHTML` –
but there is no `assertNotInHTML`.
This is very straightforward to implement – and I suspect more than a few
projects will already have their own implementation if they need this, but
I think it’d make much more sense to have this out of the box considering
other "<needle> in <haystack>" assertions have their `-not` equivalent
built in. For me, the main source of pain here is that I use this often
enough to use this but rarely enough to frequently forget:
- Whether this is a Django built-in or not. So I look at
[https://docs.djangoproject.com/en/4.2/topics/testing/tools/#assertions
assertions docs] and am surprised not to see it.
- Whether the project I work on has it or not. So again I have to look
around and potentially add it.
