This piece is great overall, but: > TDD[...] zealots are probably zealots [...] Because they're sick to death of things breaking in production and having to program against interfaces that were designed as an implementer was thinking about them over how a caller would view them. There are times and places to not do TDD, I'd say on the backend around 15% of the time where exploration first is more important (e.g., some data science thing where you don't even know the shape of the data yet) but for run of the mill programming TDD works, but most people still don't do it even if they say they do. I had my zealot phase on TDD, and what got me out of it was just resigning to the reality that the world isn't going to change. But that said, when friends / coworkers going on zealot style TDD rants I pour gasoline on that fire because I still enthusiastically agree with them.
