System Tests vs. Unit Tests

A very interesting article by David Heinemeier Hansson Describing the greater value of system tests over granular unit tests. I’ve definitely seen some of David’s points play out in web systems more concerned about users interacting with the interface than intricate calculations. Although, for those web applications where one small bug might cause significant monetary loss, like in financial related software, seems unit tests would still be extremely relevant.
