Chaos Engineering has appeared as a very useful practice for increasing application resiliency. However, most teams start using Chaos Engineering only after incidents happened and after a lot of pain in dealing with the reliability issues. Is it possible to have a proactive reliability practice, a shift-left in this domain, similar to what TDD is
