It doesn't seem important at all, until you get a batch of boards with a
blob on a photoplot that puts shorts on every board, and the manufacturer
denies liability since you didn't pay for testing. This hasn't happened to
me, but I've heard of it.
But why not use a PCB fab who include testing for free on all orders ?
