I disagree. I started learning programming seriously on my own, using Ruby. And TDD/testing was built into most sources I could find (books and courses, not random blog posts) so I started doing it almost right away. It’s paid huge dividends ever since and it’s not rare for me to join a larger corporate/enterprise type of environment and be the only one who seems to even be aware of automated testing as a concept.
