Hello! I'm currently upgrading a project from Django 2.2 to 3.2 (a bit
sloppily, as I'm not incrementally upgrading to intermediate versions). I
noticed that a few of my tests rely on the following behavior specified in
the documentation for the Http404 exception:
> When DEBUG is True, you can provide a message to Http404 and it will
appear in the standard 404 debug template. Use these messages for
debugging purposes; they generally aren’t suitable for use in a production
404 template.
I was able to test whether the message I passed was visible on the debug
404 page for the view (to make sure the page was 404'ing for the right
reason). However, these tests have broken when upgrading to Django 3.2.
Looking at the actual response content, it doesn't seem as though the
actual message is visible anywhere on the page.
I'm currently just going to comment out the explicit test for finding the
exception message, but I was curious if anyone else has found this kind of
error as well, or if it's just me. If needed, I can try creating a simple
test case that reproduces this error (though I'll admit the problem could
be entirely on my end too).
