Testing isn’t, or shouldn’t be, about finding bugs. Type-1 Testing is about ensuring you can go to Type-2 Testing and get some useful feedback. Customer feedback is the really valuable stuff: does your product address the need you saw? Is there more to do? More value to be got? – and does the value delivered justify the cost of doing it?
Testing-Testing 1 2 is a 13-minute video blog rerecording of a private presentation I did during lock-down, I hope you find it interesting.
