 Hello everyone,

 while migrating from django 5.0.8 to 5.1, I experienced a change in
 behavior when running unittests. We are using ManifestStaticFilesStorage,
 and during development and unittesting, collectstatic have never been
 called, as static files were only required for the final result.

 This did not pose a problem in 5.0.8, but after switching to 5.1, tests
 using templates with static-templatetags failed with "Missing staticfiles
 manifest entry for 'admin/css/base.css'".

 Of course, there are multiple ways to fix this for a given project, such
 as
 * changing settings.py to use simple StaticFilesStorage during tests (e.g.
 detected by environment variable)
 * running collectstatic before running tests

 But, as the problem is not described in Release Notes or
 https://docs.djangoproject.com/en/5.0/topics/testing/overview/, users
 might be puzzled first.
 Not sure what the best way to deal with this issue would be, but maybe it
 could at least be added to documentation?
