I propose "Granshaw's law". Every time the value of unit tests is discussed the debate over static vs dynamic typing must be looming eerily in the background.

I propose "Granshaw's law". Every time the value of unit tests is discussed the debate over static vs dynamic typing must be looming eerily in the background. That said, as someone who has spent the majority of his career writing dynamically typed code I can definitely recall far more instances where statically typed code has run and worked first time vs times when I've written some code with unit tests and it worked first time.
