python - Suddenly when running tests I get "TypeError: 'NoneType' object is not iterable -


this phenomenally strange me, things working fine until morning.

when attempt run unit test using following (i have python3 soft linked python)

clear; python manage.py test list tests/

i following error message: 

traceback (most recent call last):   file "manage.py", line 10, in <module>     execute_from_command_line(sys.argv)   file "/usr/lib/python3.4/site-packages/django/core/management        /__init__.py", line 385, in execute_from_command_line     utility.execute()   file "/usr/lib/python3.4/site-packages/django/core/management        /__init__.py", line 377, in execute     self.fetch_command(subcommand).run_from_argv(self.argv)   file "/usr/lib/python3.4/site-packages/django/core/management/commands    /test.py", line 50, in run_from_argv     super(command, self).run_from_argv(argv)   file "/usr/lib/python3.4/site-packages/django/core/management    /base.py", line 288, in run_from_argv     self.execute(*args, **options.__dict__)   file "/usr/lib/python3.4/site-packages/django/core/management/commands    /test.py", line 71, in execute     super(command, self).execute(*args, **options)   file "/usr/lib/python3.4/site-packages/django/core/management    /base.py", line 338, in execute     output = self.handle(*args, **options)   file "/usr/lib/python3.4/site-packages/django/core/management/commands    /test.py", line 88, in handle     failures = test_runner.run_tests(test_labels)   file "/usr/lib/python3.4/site-packages/django/test/runner.py", line     146, in run_tests     suite = self.build_suite(test_labels, extra_tests)   file "/usr/lib/python3.4/site-packages/django/test/runner.py", line     101, in build_suite     suite.addtests(tests)   file "/usr/lib64/python3.4/unittest/suite.py", line 60, in addtests     test in tests: typeerror: 'nonetype' object not iterable

i thought wrote messed up, saved branch, reverted in master branch commit works exact same error message.

i can't think of did make things fail this, in fact, above doesn't point i've written (in case, i'm relatively new python/django) making difficult me debug error.

the thing can think of changed installation of the silver searcher (i use vim) removed , still same error happens.

i've reinstalled django, still no avail.

this on:

  • opensuse 13.2
  • django 1.7
  • python 3.4.1

can me out in

  • debugging cause of error (so don't fall in again)
  • how go fixing this?

thank you

i wasn't able explain why so, when ran "python manage.py test list/" without specifying file name, things worked well.

thanks user ella shar, changing scheme/layout set tests approved dotted format described in documentation
