How to reuse Django tests? -


i'm extending django queryset subclass (say myqueryset), , guarantee implementation not break existing functionality of queryset.

how can test myqueryset against existing django tests on queryset without having replicate them?

for concreteness, let's consider example of tests of prefetch_related, found in django/tests/prefetch_related package.

i run tests on myqueryset. however, tests implemented using default manager of models in package. have idea how e.g. duck type objects custom manager uses myqueryset?
