> 10-20 years ago that wasn't really the case

To state the obvious, 10 years ago was 2012. Absolutely all of the things you list were standard practice. 20 years ago was 2002, also same thing (no, git didn't invent version control).

30 years ago I was using version control at my first job, it was expected practice. As was having test coverage. None of these things are new.

Deployment was different, granted. We didn't "deploy to production", we shipped a box of floppies to users.
