I'm doing a very simple frontend and backend thingy. I'm basically vibe coding my own project management tool in the way I like it. I'm currently at 4000 lines of code and am beginning to get to the threshold that I can't take technical debt anymore and would need to restructure and refactor.

So yea, fair enough.

Though, the shift that the OP describes, yea I can see that. Writing tests has become way more important. Or well, it feels more important. From a testing perspective, we should see ourselves agents too (aka bug making machines), that's why you need tests. The silly bias I always had was "but I'm writing the code! It'll be fine, I won't make bug- oh... why can't I close my modal window when I click on the x symbol?"

But yea, the apparent need for testing is definitely much more there. The need for architecting it well is also there as LLMs still seem to be a bit in tutorial land with that one. There are a few more things like that.
