His way of "manual testing" is just development with breakpoints. I do not think that this person has ever worked on a software for more then a few months. Unit tests actually let me develop a lot of stuff faster, since i start thinking about the API first, before implementing it and therefore i shift my perspective to the API consumers point of view. Sure testing "getters and setters" is not all that helpful but i wholeheartedly disagree with the authors confidence in correctness and to just refactor the parts that feel wonky.
