Description
tests - add a new argument "--test-only" (int, >=0) and If run with this argument, run only this number of tests.
Sometimes there are thousands of tests, for example 6,000 tests, and I want to run only a random subset of them, for example 200 tests. It should be possible with Django.
The code needed to implement such a feature is:
In command test:
parser.add_argument( "--test-only", action="store", help="If run with this argument, run only this number of tests.", type=int, )
In DiscoverRunner::init:
self.test_only = kwargs.get('test_only', None) if (self.test_only is not None): assert (self.test_only >= 0)
In DiscoverRunner::test_suite:
def test_suite(self, tests=()): if (self.test_only is not None): tests = tests[:self.test_only] return super().test_suite(tests=tests)
Usage:
python manage.py test --shuffle --test-only 200
(It makes more sense to use it with --shuffle
, but you can also use it without it).
And that's all. :-)

Thanks for this ticket, however, I think it's a bit of a niche case. The current thread is to keep Django a core framework, not providing every utility which might be useful.
Please first start a discussion on the DevelopersMailingList, where you'll reach a wider audience and see what other think, and follow the guidelines with regards to wontfix tickets.
