You'll only read what you're used to do daily. And to thank you for stopping by, here's a nice photo of a dog:

So, if you're still here, it means you're in doubt of how CI/CD will play a role in our software development utility belt. Although we all know that automated tests and even a simple CI/CD infrastructure are the foundation of modern software development practices, I wasn't able to answer their questions right on spot. I mean, it's obvious that what we do has benefits, but we still don't know how to quantify them. Often, we see folks banging their heads against the wall trying to figure out _wh
