zope.testing.doctestunit emits a deprecation warning. It also defines a function pprint. How does one use pprint without getting a deprecation warning? It seems impossible now, and an equivalent pprint doesn't appear to be in the standard library doctest..
When I recently converted some tests, I replaced that pprint function with the one from the standard library:
from pprint import pprint
There weren't any differences in the output, as far as I could tell.
Not sure if this is related, but one thing I found which bit me recently is that prior to Python 2.5, pprint did not sort dict keys in the output. That means that a test like this:
>>> pprint(foo) {'omega': 1, 'alpha': 2}
will pass on 2.4 and fail on 2.5/2.6; to fix it for 2.5/2.6 you do:
>>> pprint(foo) {'alpha': 2, 'omega': 1}
but now it fails on 2.4. The only way I could find it make it work reliably was to not rely on dicts at all, but do:
>>> pprint(sorted(foo.items()) [('alpha', 2), ('omega', 1)]
Which works the same on both. I don't know if the zope.doctest pprint function was meant to fix this, but maybe it did?
That could be it. It seems silly to have a whole module just for that, but we can change the deprecation to just deprecate the BBB imports. -- Lennart Regebro: Python, Zope, Plone, Grok http://regebro.wordpress.com/ +33 661 58 14 64
