34210	Show the duration of individual tests	Paolo Melchiorre	David Smith	"I propose to add the possibility to show the duration of individual tests in the final report by ordering them from slowest to fastest and filtering only the slowest tests with a threshold.

Example:

{{{
$ python -m manage test --durations=10
Found 92 test(s).
Creating test database for alias 'default'...
System check identified no issues (0 silenced).
Creating test database for alias 'default'...
..........
----------------------------------------------------------------------
Ran 92 tests in 1.297s

OK
Destroying test database for alias 'default'...

Slowest 10 test duration durations:
0.3597s test_detail_view_with_a_future_poll (polls.tests.PollIndexDetailTests)
0.0284s test_detail_view_with_a_past_poll (polls.tests.PollIndexDetailTests)
0.0068s test_index_view_with_a_future_poll (polls.tests.PollViewTests)
0.0047s test_index_view_with_a_past_poll (polls.tests.PollViewTests)
0.0045s test_index_view_with_two_past_polls (polls.tests.PollViewTests)
0.0041s test_index_view_with_future_poll_and_past_poll (polls.tests.PollViewTests)
0.0036s test_index_view_with_no_polls (polls.tests.PollViewTests)
0.0003s test_was_published_recently_with_future_poll (polls.tests.PollMethodTests)
0.0002s test_was_published_recently_with_recent_poll (polls.tests.PollMethodTests)
0.0002s test_was_published_recently_with_old_poll (polls.tests.PollMethodTests)
}}}

`pytest` has a very similar option that helps you find slower tests that you want to optimize their timing.
https://pytest.org/en/latest/how-to/usage.html#durations

There's an external package `django-slow-tests` that adds a similar functionality, but the code is very old and with very little test coverage, furthermore the last release was almost 4 years ago and the officially supported versions of Django are very old.
https://github.com/realpython/django-slow-tests

I propose to add this feature directly into Django tests to help users optimize their tests and also to help Django developers optimize the test of Dajngo itself."
