We had separate test and production instances in about 1994/95 but that was Pharma (regulated)… when I moved to Web it was very cowboy style for a few years, don’t think we had a safe testing or dev environment until maybe 2001 then the whole thing tanked anyway. Funny thing is after that I worked for a big company with a lot of “best practices” and except for me, for about six glorious months, nobody was ever able to run the full product on their dev machine. So I assume there is still a long way to go in most companies. The bugs I see in FAANG software are also, as often as not, of the “clearly the dev never really ran the code” variety.
