24364	Document that ManifestStaticFilesStorage shouldn't be used during testing	Nathan Vander Wilt	Aksel	"I recently switched a project to the ManifestStaticFilesStorage backend for the ""permacacheable"" URLs it gives to resources that may change. However, this seems to have broken some of my Selenium tests, which use `StaticLiveServerTestCase` for the browser resources.

Now when I try to run my tests, they fail. I get a bunch of stacktraces that read

    ValueError: The file 'images/favicon.ico' could not be found with <django.contrib.staticfiles.storage.ManifestStaticFilesStorage object at 0x1037ed290>.

Running `./manage.py collectstatic` before the tests makes the problem go away, but this is a poor workaround (it leaves stale resources which become confusing during development). Accessing the site works just fine via `./manage.py runserver`, but is it expected for tests not to work in this configuration?"
