I see this in Android. Every few years (sometimes multiple times in a year) a new arch. becomes the fad and every TDH dev starts hankering for one way or the other on the lines "why are you not doing X..". Problem is, at immature firms (specially startups) the director and senior manager level leaders happily agree for the re-write i.e re-archs because they usually leave every season for the next place and they get to talk about that new thing which probably didn't last beyond their stay, or might have conked off before that. And the "test cases" porn! Goodness! People want "coverage" and that's it. It's a box to tick, irrespective of whether those test cases and they way those are written are actually meaningful in anyway. There are more like "let's have dependency injection everywhere" charade.
