I feel like I'm on a completely different wavelength with those who offer up "full test coverage" as a desirable alternative to a type system's assistance. Or a desirable situation period. I'm all for tests as a tool, but not full coverage as its own goal. One of my favorite tools is Visual Studio Code. As far as I can determine from the github repo it is very far away from the full coverage end of the spectrum. And yet, it works pretty darn good. Maybe I just haven't found the unit test hoard, but it appears they have taken a more strategic, moderate approach.
