Yes, that would be very good to have indeed.

Nice! I'd be happy to play with it, if it can:
- handle doctests in extension modules
- handle doctests written with ipython prompts (or be taught how to
via a plugin, like I had to do for nose)
- easily be told how to run just one file, or even just one function
inside one file:
maqroll[~]> iptest IPython.tests.test_magic
----------------------------------------------------------------------
Ran 10 tests in 0.348s
OK (SKIP=3)
Deleting object: second_pass
maqroll[~]> iptest IPython.tests.test_magic:test_obj_del
----------------------------------------------------------------------
Ran 1 test in 0.204s
OK
- How to ignore random output in doctests, either in just one entry or
for the whole doctest, but still executing the code
- Stop at the first failure
- Load pdb interactively on failures, so I can debug things right there.
Does it have those things? Nose ain't perfect, but it's pretty darn
useful even without green 'ok' printouts ;)
Cheers,
f
