Why Passing Tests Aren’t Proof of Correctness: Dijkstra’s Insight & Modern Strategies

The article explains that a green test run only shows the absence of detected bugs under specific inputs, environments, and assumptions, explores the asymmetry between verification and falsification, discusses the test‑oracle problem, property‑based testing, formal verification, and proposes a risk‑calibrated testing approach.
