It looks like your email is missing a footnote.

I think I've figured out the namespace package issue, but that doesn't
seem to help here -- I'm seeing 0 lines executed in zope.dottedname in
coverage report.  If I pass --coverage-include to nose, it shows two
lines of code (just the outer level, with the def statement) in
zope.dottedname.resolve.

Ah!  Other zope.* packages on Github have a coverage section in tox.ini
with the pip uninstall/pip install -e steps but _without_ the shutil
trick.

tox -e coverage works for them nonetheless.

(I did a pip uninstall followed by easy_install zope.testing and python
setup.py develop, which also gave me proper namespace package support,
but didn't help with coverage numbers.)

(It's annoying how one must repeat all the test dependencies here, as
well as in setup.py.)
