Hi there, [extensive introduction by Uli of zope.pytest] Thanks Uli for that introduction to the package and its problems! I've been using zope.pytest within 2 Grok projects so far to test through webob some JSON webservices, and it's worked well for me. I hadn't had to deal with the issue of multiple configurations in those tests though, as they're basically functional/integration tests. I've also been happily using plain py.test in several other non-Zope projects, and I must say it has many nice features that make life easier, and makes a lot of test cruft go away. I'm particularly hoping that Wolfgang Schnerring will give feedback: I'm curious how his investigations on improving the layer story might also benefit py.test integration. Regards, Martijn P.S. Uli did a lot of work himself to make this package and help document it, by the way, he's doing himself injustice in his introduction. :)
