The approach mentioned here http://docs.python.org/dev/library/doctest.html#unittest-api gets the doctests run, but is kinda bogus (you get 2 sets of test runner output).  Glancing at unittest2's discovery stuff, it seems to look for TestCases, but not TestSuites. Just wondering if there's something obvious I'm missing, or if I should start poking through/ripping off doctest's implementation of integration (which is lightly documented).

JFTR and pseudo-OT, using `dutest` you could do

{{{
#!python

def load_tests(loader, tests, ignore):
   from dutest import defaultTestLoader
   tests.addTests(defaultTestLoader.loadTestsFromModule(module_with_doctests))
   return tests
}}}

and then you'll load both instantiated unittests TCs as well as TCs
(wrappers) to run your your doctests (with enhanced test reports as a
side effect ;o) . You could also specify more sophisticated things
like setting up doctest flags (e.g. REPORT_UDIFF) , and more ... but
this is JFTR

;o)
