Failing to Run AutodetectorTests Using runtest.py (25253)

[Shun Yu]

I'm trying to run the "migrations.test_autodetector.AutodetectorTests" for django, but I can't seem to get it to work.

I'm using Windows 10 and Python 3.6.2.

Below is the output I'm getting, thanks for the help!

C:\Users\Shun\.virtualenvs\django-original-test\Scripts\python.exe C:/Users/Shun/Desktop/django/django/tests/runtests.py --settings=test_sqlite tests.migrations.test_autodetector.AutodetectorTests

When I try to run the whole test suite it works fine, it's just that when I try to run this specific one it's failing on me.

I can see the problem as well, and I can see it in 2.0 and 1.11 too. Please
open a new bug on the testing framework.

The "tests" prefix shouldn't be included in "tests.migrations.test_autodetector.AutodetectorTests". Perhaps runtests.py could raise a helpful message for that mistake.
