> ... 100% coverage requirement of the codebase ... Is 100% really practical? Probably in life or finance critical code. What about those "should never happen" cases? Incredibly hard to trigger because you only know from gut feeling it can happen in some really weird way. I know it would feel very nice to have 100% coverage, but my gut feeling is that it will also affect the code base in a negative way. Developers might skip catching errors that would be very hard to reach.
