Comment (by sirex):
Recently I started to work on a project, that uses Django 1.7, and found,
that running one small test, takes about 10 seconds, white the test itself
takes 0.001s! I love TDD, but with Django 1.7 it became impossible.
With South, there was
[https://south.readthedocs.org/en/latest/settings.html#south-tests-migrate
SOUTH_TESTS_MIGRATE] option and with this option running single test was
instant.
Also, I have [https://github.com/python-
dirbtuves/akl.lt/blob/master/scripts/runtests.py#L29 a helper script],
that allows to switch database to in memory SQlite easily, this makes
tests even faster, because 98% of all tests works perfectly without
PostgreSQL. So I only switch to PostgreSQL for running tests, when I need
to.
In other words, running one single test has to be instant fast. If Django
itself takes 10 seconds to start, it is deal breaker for everyone who uses
TDD.
