Okay. I narrowed the problem down and created a minimal test case. I created two projects, myns.projA and myns.projB. myns.projA is stock basic_namespace project with one module added. First, I created myns.projA with the basic_namespace template from ZopeSkel:

paster create -t basic_namespace Selected and implied templates: zopeskel#basic_namespace A project with a namespace package

cat > myns.projA\myns\projA\modA.py def funcA():

Enter project name: myns.projA Variables: egg: myns.projA package: mynsproja project: myns.projA Enter namespace_package (Namespace package (like plone)) ['plone']: myns Enter package (The package contained namespace package (like example)) ['example']: projA ... (rest are defaults) Then I added a single module with a simple function print "funcA called" ^D myns.projB is another project created basically the same way, but they key to getting the bug to surface was to put the packages in a sub-directory... so I modified setup.py with the following parameters to setup: packages=find_packages('src'), package_dir={'': 'src'}, test_suite='nose.collector', And of course, I moved the myns directory to src/myns. Note, this only had to happen for myns.projB. Finally, I created a test directory and a file testBasic.py

cat > test/testBasic.py from myns.projA.modA import funcA ^D

Note, I could add a dependency from myns.projB on myns.projA, but it's not necessary for this demonstration. Then, I either setup myns.projA with either "install" or "develop" so that it's visible to the Python installation. Thereafter, if I try to run "setup.py test" on myns.projB, I get the ImportError. See error.txt, attached, for the transcript. I've also attached the two test packages as described. I notice now that the error appears to only occur when nose.collector is used... and when the package_dir of the child package is overridden. Perhaps this needs to go to the nose project and instead of the distutils project. Please advise on what I might do next to help resolve this issue. Obviously I could restructure my projects to avoid the problem, but I would much rather help resolve the problem, as I suspect it may affect other users' deployments as well.

If there's not something obvious I should be doing differently, I'm happy to put together a minimal test case that reproduces the problem.

Please do. Thanks!

Phillip, You're right. I was running the tests on my two Windows Vista environments, and now I discover the problem only exhibits itself under Windows. I expanded the packages to my Ubuntu 8.04 box, and after installing nose (as you pointed out), the tests also ran (minimally) without incident. I then copied the packages to a brand-new Windows Vista install. I installed Python 2.5.2, setuptools-0.6c8, and nose 0.10.3. I then installed myns.projA using develop, and attempted to run "setup.py test" on myns.projB, and the error did exhibit itself. Additionally, I tested the sample on Windows XP (Python 2.5.2) and it also exhibits the error. Thanks to your help, I've further narrowed down the problem. I have filed a ticket with the nose tracker: http://code.google.com/p/python-nose/issues/detail?id=197 Any further suggestions are always appreciated.

Coombs; distutils-sig@python.org Subject: Re: [Distutils] ImportError running 'test' on namespace package - other package in namespace not found I can't reproduce this using the archive you uploaded. After running develop on projA, I ran test on projB and got an error message about nose not being available, so I added tests_require="nose" to projB, and then I got a run that said zero tests ran.
