Multi Environment Testing for Critical Systems

When deploying software for critical systems in fields like robotics or fintech, relying on a single staging environment for testing rarely provides sufficient reliability. This talk explores the unique QA lifecycle that supports such systems, emphasizing the layered safety nets that protect both users and infrastructure. From simulation environments to controlled staging setups and finally on-site validation, each phase is designed to catch issues before they escalate. Equally important is the discipline of balancing thorough testing with development speed—a crucial requirement for any software project where delays can ripple across teams and impact delivery. The talk also covers how QA professionals navigate this tension, optimizing test coverage without compromising velocity. Marius-Mihail Gurgu (QA Engineer @ KOMOJU) I'm a QA engineer with experience in robotics and fintech systems, applying what I learned from academic research in autonomous drones to real-world testing. With a background in embedded systems and dual MSc degrees, I build testing frameworks to ensure reliability in complex, real-time environments.
