The doc about how to ignore warnings in tests is here:
https://docs.djangoproject.com/en/dev/internals/contributing/writing-code/submitting-patches/#deprecating-a-feature
Alternatively, you can temporarily remove these lines in runtests.py:
warnings.simplefilter("error", RemovedInDjango20Warning)
warnings.simplefilter("error", RemovedInDjango21Warning)
