Watch a conference talk from NDC TechTown that explores effective strategies for preventing catastrophic software failures through Property Based Testing (PBT). Learn from the UK air traffic control incident of 2023, where over 2,000 flights were cancelled due to duplicate waypoint markers, to understand the critical importance of robust testing. Discover how the Scientific Computing team at Equinor implements the hypothesis property based testing tool, comparing its effectiveness to traditional testing methods. Explore how PBT can be integrated early in the development process to minimize debugging efforts and enhance software reliability. Gain practical insights into managing the cost-risk-benefit balance of bug prevention in software projects through this 43-minute presentation delivered in Kongsberg, Norway.
