I haven't had time yet to review this in detail, but this is most
definitely the right direction: separate tests from documentation,
make the tests expressive and the documentation clear. Wonderful!
(I've I get some 'round toits, I'd much like to look through this;
I'll let you know if I find anything.)
Great, thanks!
Unless the consensus is against it, I plan to merge this branch to
the trunk early next week.
+1, please do.
The branch makes many fewer Zope-y assumptions about how it is
developed. In particular, in a fresh checkout, you can run the
tests and build the docs with widely-used 3rd-party tools, without
needing to set up a buildout::
Since I've thinking along these lines recently (why do I need
buildout if all I want is a testrunner?), I'm curious as to how this
works, especially - Where does bin/nosetests come from? - Where does
setup.py docs come from?
The 'docs' and 'dev' aliases are defined in setup.cfg::
$ tail -n -3 setup.cfg
[aliases]
dev = develop easy_install zope.interface[testing]
docs = easy_install zope.interface[docs]
and their extras_require in setup.py::
$ egrep -B 2 (testing_extras|'docs') setup.py
features = {'codeoptimization': codeoptimization}
tests_require = ['zope.event']
testing_extras = tests_require + ['nose', 'coverage']
--
tests_require = tests_require,
install_requires = ['setuptools'],
extras_require={'docs': ['Sphinx'],
'test': tests_require,
'testing': testing_extras,

Thanks for the catch. This was indeed a fix for a problem I uncovered
while ensuring that the Python and C implementations passed the same test
suite. I have update the 'CHANGES.txt` file on the branch to indicate
the fix.
