In my largish company, the CTO announced a similar "zero regressions in production" goal. I came up with this system of coverage which would be a huge improvement and much tighter testing process, eventually moving "left" up the development pipeline: https://eratestcoverage.org/ https://eratestcoverage.org/ I proposed this and a bunch of other ideas, and the general reaction was flat. My boss said he didn't understand any of it and cut me off trying to explain. I realize now, the goal set by the CTO was just talk, they had no interest in any real process change. And so, nothing changed. The concepts are sound, granted they could be better explained, I'm working on it, just not being paid to do so.
