My colleague Sarah Taraporewalla posted an interesting text on acceptance testing. She doesn’t believe in this technique. I’ve been thinking of acceptance tests for some months now and think that she has a valid –a bit too radical but still valid- point.
My main problem with acceptance testing is that they are too wasteful.

My friend Mark Needham wrote a blog post on the Domain Model pattern and Domain-Driven Design recently. He changed a bit the contents but the original question was: Should we always use Domain-Driven Design? In response, the author gave an overview of several architectural patterns for domain logic.
