> Experiencing a well-tested code base totally changed things for me. Instead of work being a death-of-a-thousand-cuts experience, it became pleasant, steady progress.

I had the luxury of taking a well known data process and rewriting it with integration tests (input in, matching output with a golden file). It changed my professional life. Whereas before our deployment process included a 3 day wait and manual data checking on stage, after I was able to do deploys multiple times a day with confidence.

Made a believer out of me.
