Cached values were leaking across tests, causing difficult to debug errors, particularly when using Config Models. As part of this work, certain tests that had query counts that relied on those values being cached needed to be adjusted up.

THE TESTS IN THIS MODULE SHOULD BE RUN ON THE SAME PROCESS TO BE MEANINGFUL!!!
|
|
|
|
The tests in this module look kind of goofy, but the idea is to make sure that
|
|
cache values can't leak between different TestCase classes and methods. The need
|
|
for this will go away whenever Django merges the fix to reset the caches between
|
|
tests (https://code.djangoproject.com/ticket/11505).
