Your interpretation seems like a reasonable scale - however, it is a very vague definition of "0". I'm sure some people want a 0 to mean an actual 0, like a blind developer asked to do UI development.

Interfaces aren't only visual - blind users still have to interact with something.

Yeah, sounds like a joke. But I worked at a company where the tech writer was legally blind, the marketing guy was shy and the spokesperson (CEO) stuttered. Weird place.

OK, let's take 0 to mean does not write tests on principle and 1 to mean writes minimal tests grudgingly if required by policy.
