Comment (by carljm):
Besides test discovery, the other thing this gives you is a more powerful
way to specify which tests to run via commandline, by using real dotted
path rather than the pseudo-dotted-path
`applabel.TestCaseClass.testcasemethod`. Right now, if your tests within
an app are split into submodules, there is no way to say "run just the
tests in this module." You have to run either the entire app's tests, or a
single `TestCase` subclass. With this runner, you can just give the real
dotted path to the module.
So we could make this the default for new `startproject`s without breaking
back-compat. The biggest question is how to set `TEST_DISCOVERY_ROOT` by
default. This is a bit of a puzzle, since we currently don't preset any
settings with paths (e.g. users have to set `TEMPLATE_DIRS` and
`STATICFILES_DIRS` themselves), and I'm not really interested in
reintroducing any magic "find the project directory" code. I suppose one
option would be to have `TEST_DISCOVERY_ROOT` default to empty, and if
it's empty discover tests in all `INSTALLED_APPS` (but with robust
discovery that includes all files matching the test* pattern, including
sub-modules, not the "models.py and tests.py only" approach that we have
now). Then if someone prefers keeping tests outside of apps, they could
set `TEST_DISCOVERY_ROOT` to their preferred location.
