“I'm researching a small CI diagnosis agent, but I'm first trying to understand how experienced engineers actually debug these failures. Suppose an integration test fails in CI and the logs don't immediately reveal the root cause. What do you normally investigate first? For example: CI logs/stack trace database availability dependent/third-party service availability recent code changes comparison with the previous/last-green build test/DB data previous failure history rerunning the te”

“Just curious, standard procedure, you have something working locally, you push your code and your CI/CD pipeline fails. Locally everything seems OK and you fail to reproduce the error. What do you actually do at that point? Genuinely curious what people's real routine looks like here — not the textbook answer, the actual "it's 5pm and CI fails" routine 😅 Also wondering: is this even still a big thing in 2026 now that lockfiles and containers have gotten so good, or is it basic”
