I have not seen tests in any code base I worked on in the past 20 years. I have noticed that there is some kind of sanctimonious demeanor to quite a few people that advocate for tests (on comment boards). I find the reactions to discussions on tests fascinating because it seems to elicit very strong opinions, sort of a "do you put your shopping cart back" kind of topic, but for programmers.

I find that fascinating, because interacting with the tests in our codebase (both Python and JS) answers a _lot_ about "how is this meant to work", or "why do we have this". I won't say I do test-driven development, at least not very rigorously, but any time I am trying to make a small change in a thing I'm not 100% familiar with, it's been helpful to have tests that cover those edge cases. :)
