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.

 From zope.component's tox.ini::
 
 
  [testenv:coverage]
  basepython =
  python2.6
  commands =
  #   The installed version messes up nose's test discovery /
  #   coverage reporting
  #   So, we uninstall that from the environment, and then install the
  #   editable version, before running nosetests.
  pip uninstall -y zope.component
  python -c import shutil; shutil.copyfile('src/zope/__init__.py',
 '{envdir}/lib/python2.6/site-packages/zope/__init__.py')

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.

  pip install -e .

(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.)

  nosetests --with-xunit --with-xcoverage
  deps =
  zope.component
  zope.testing
  zope.hookable
  ZODB3
  zope.location
  zope.proxy
  zope.security
  zope.configuration
  zope.i18nmessageid
  nose
  coverage
  nosexcover

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