Aug 23, 2026 Symbolic Execution Found an Integer Overflow My 94% Test Coverage Missed Your unit tests check specific inputs. Symbolic execution checks every possible input. Here's how it works, what it costs, and where to start. additional-strategiessymbolic-executiontestingverification
Aug 3, 2026 How to prove your code has no runtime errors (and why you'll probably give up trying) Abstract interpretation lets you prove runtime errors impossible before execution. abstract-interpretationstatic-analysisruntime-errorsverification
Jul 25, 2026 Did anyone actually verify 10,000 lines with zero defects? IBM did, and the methodology is stranger than the result. Cleanroom software engineering promised zero-defect increments through mathematical verification instead of debugging. cleanroom-correctnesszero-defectsverificationcase-study
Jul 9, 2026 AutoVerus turns 40 hours of proof writing into 3 LLM calls. The trick is knowing when to give up. AutoVerus uses a network of LLM agents to generate Verus correctness proofs for Rust code, automating over 90% of proof obligations through a... model-checkingautoverusrustverification
Jul 6, 2026 You Can Model-Check Code Without Learning Temporal Logic Bounded model checkers like Kani and relational model finders like Alloy let you verify properties with ordinary assertions and constraints. model-checkingtemporal-logicformal-methodsverification
Jul 5, 2026 You can prove Rust code correct without writing a single proof, but the state space is the bill Model checking tools like Kani let you verify Rust properties with assertions instead of formal proofs. model-checkingrustverificationformal-methods
