 Today, when running tests, Django uses the production storage for uploaded
 files -- meaning any tests which upload files will save copies of them,
 under different names, for every test run.

 We need to treat this essentially like we treat mail -- during tests, a
 special file-storage should be set up to receive the uploads. Like with
 mail, it is probably better for this folder to be kept after the test run
 ends, and be cleared only when the tests are run again; but this is of
 lower priority.

 This should be the default, or enabled easily in settings.

 As @apollo13 noted, Django's own tests define an environment variable:
 {{{#!python
 TEMP_DIR = tempfile.mkdtemp(prefix='django_')
 os.environ['DJANGO_TEST_TEMP_DIR'] = TEMP_DIR
 }}}
 and all storages used in the suite use it or a subfolder. This alone,
 however, is not enough for user tests, as there is currently no way to
 define separate storages for test and production.
