An excellent example of functions acting as namespaces is nosetest's
@attr() decorator. We use this, for example, to tag certain test cases
as being reliant on facebook being up(*):
@attr('facebook', 'services')
def test_some_facebook_thing():
# whatever
this lets us turn all those tests on or off with a single switch. The
way @attr() is implemented, it sets attributes on the decorated
function. It's the most logical and obvious place to store a piece of
information about a test case -- right on the test case itself.
Similarly, we've got tests that we annotate as being dependent on itunes
being reachable, depending on certain data existing in the database(**),
being too slow to want to run all the time(**), etc.
(*) and please don't tell me that tests shouldn't depend on external
services.
