Is there an equivalent for "tests_require" in buildout.cfg/ zc.recipe.testrunner? The reason I ask is this... currently the zope.18n distribution has an install_requires that looks something like this: install_requires=[ 'setuptools', 'pytz', 'zope.i18nmessageid', 'zope.component [zcml]', 'zope.configuration', ] That's actually a no-good pack of lies, though. ;-) I'd like to change setup.py to something like this: test_suite = "__main__.alltests", # to support "setup.py test" tests_require=[ 'zope.testing', 'pytz', 'zope.component [zcml]', 'zope.configuration', ], install_requires=[ 'setuptools', 'pytz', 'zope.i18nmessageid', 'zope.component', # *we* do not require zope.configuration at all. Our tests # do (for silly reasons) and the framework which uses our zcml # does. ], But I want buildout tests to continue to work. I suspect the rest of this discussion is going to hurt. ;-) - C
