13016	Invalid ForeignKey ids in fixtures do not cause any error messages	Art <artem.skvira@…>	nobody	"When referencing a non-existing entity instance in fixtures for ForeignKey relationship no error message is thrown in test runner mode (./manage.py test). Please note below how in fixtures instance of Parent contains invalid ID for Child object (2 instead of 1).

This seems to be related to ""always opened transaction"" natures of tests, because if I run ./manage.py testserver data.json I actually get an exception thrown.

Backend is Postgresql 8.3.
