Great article describing where is it beneficial to use unit testing. I agree with Steve I’d rather spend an hour writing integration tests to prove the whole system works together in some scenario, rather unit testing a trivial code of my web application controllers.

This article by Udi Dahan describes techniques how to keep the business in the domain using domain events for more complex interactions. A typical scenraio is “When a customer has become a [something] the system should [do something].” where there may be several use cases how to become a [something] and we don’t want to duplicate code, nor handle event subscriptions in the code calling the domain model.
