3.15.1: pytest fails wit error in tests/test_testing.py::TestUrlPatternTestCase::test_urlpatterns unit

[wuch-g2v]

Checklist

• Raised initially as discussion #...
• This is not a feature request suitable for implementation outside this project. Please elaborate what it is:
  • compatibility fix for new Django/Python version ...
  • other type of bug fix
  • other type of improvement that does not touch existing code or change existing behavior (e.g. wrapper for new Django field)
• I have reduced the issue to the simplest possible case.

Looks like something is wrong and pytest fails in one unit
