Keynote: Yes, I Test In Production... And So Should You Testing in prod has gotten a bad rap. It's both inevitable - you can't know everything before you ship - and desirable. In modern complex systems, failure is a constant and the only guiding principle is that "users should never notice". So how do you test safely in prod, and how should you allocate your scarce engineering cycles between prod and staging? Charity Majors - https://twitter.com/mipsytipsy EuRuKo 2019

In her keynote speech titled "I Test In Production," Charity Majors discusses the importance and inevitability of testing in production environments, arguing for a paradigm shift in how software testing is approached. The prevailing notion that testing should only occur before or after deployment is challenged by Majors, who insists that responsible engineers constantly test in production. She emphasizes that modern systems are inherently complex, and it is impractical to replicate production environments in staging. The key takeaways from her talk include: - Testing in production is often avoided due to misconceptions, but it should be integrated as a responsible practice for improving system reliability. - Traditional testing methods are not sufficient for the complexities found in contemporary software systems, which require developers to engage directly with production. - Engineering resources are finite, and it is crucial to spend developer cycles wisely, focusing on understanding real usage in production rather than getting lost in potentially misleading staging environments. - Observability and monitoring are essential tools that help developers understand system performance and issues as they arise in the wild. - Engaging with production allows developers to learn and adapt their instinct about system behaviors and failures, which is vital for their growth and the reliability of the systems they manage. - She encourages engineers to embrace failures as part of the process, creating environments where significant failures can occur without impacting user experience. - Majors critiques the heavy reliance on staging, noting that it can waste valuable time and lead to misplaced confidence in a system's stability. - The conclusion of her talk is optimistic, advocating for embracing production as a learning environment where real user interactions can lead to better software outcomes. Overall, testing in production is not just a technique but a necessary attitude shift that prioritizes real-world relevance over theoretical safety.
