Comment:

 This should be fixed in Django 3.1 by using the new
 [https://docs.djangoproject.com/en/dev/ref/settings/#migrate MIGRATE] test
 database setting that allows disabling of migrations during a test
 database creation (see #25388).

 Fixed in f5ebdfce5c417f9844e86bccc2f12577064d4bad.

Comment (by Sergey Yurchenko):

 I have the same problems with creation of test db.
 For tests I don`t use migrations but models directly like in older
 versions of Django without migrations.
 Tests with migrations run is CI to check that migrations are correct so
 nobody cares about time.

 {{{
 class DisableMigrations(object):
 def __contains__(self, item):
 return True

 def __getitem__(self, item):
 return None

 }}}

 in your settings.py

 {{{
 MIGRATION_MODULES = DisableMigrations()
 }}}

 Is `/home/anoosha/django` using Django's master branch? The traceback
 shows line numbers that makes me think it's not.

 What output do you get from either:
 print INSTALLED_APPS #Python2.x
 or
