Even better: use the documented setuptools keyword 'tests_require', and get the testrunner / buildout to use that hook when running tests. An added benefit is that it might even be possible for somebody to run the tests from a subversion checkout / unpacked sdist without first running buildout, by just running 'python setup.py test'. This last will require defining a workable 'test_suite' keyword, as well.  http://peak.telecommunity.com/DevCenter/setuptools#id7 Tres. - -- =================================================================== Tres Seaver +1 540-429-0999 [EMAIL PROTECTED] Palladion Software "Excellence by Design" http://palladion.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFIAWlw+gerLs4ltQ4RAuq1AJ48SsGtuCUvBzTN2a1YLqGSPTBIfgCcC9ZQ GwLUzQDm6FQB6DpQ6a2bJkM= =hqQm -----END PGP SIGNATURE----- _______________________________________________ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
