Comment 3 for bug 677401

In case it can be useful, the one below is the test structure that I use in my app (app name is "bgb").
I do not use/like doctests, hence only a unit and functional test classes are provided.
Do you think it would be acceptable for grokproject to generate something similar?

=== tests/config.py ===

import os

import z3c.testsetup
from zope.app.testing.functional import ZCMLLayer

import bgb

ftesting_zcml = os.path.join(os.path.dirname(bgb.__file__), 'ftesting.zcml')
FunctionalLayer = ZCMLLayer(ftesting_zcml, __name__, 'FunctionalLayer', allow_teardown=True)

test_suite = z3c.testsetup.register_all_tests('bgb')

=== tests/test_app.py ===
