Fuzzing vs property-based testing: the terms are splitting — exploration vs assertion
blaizedsouza · x · 2026-09-20
Dominik Tornow clarifies terminology: fuzzing and property-based testing historically overlapped, but the terms are increasingly splitting — fuzzing now refers to exploration (actively hunting inputs that trigger paths), while property-based testing refers to assertion (verifying correctness via properties).
The distinction pairs with his argument that correctness comes from property assertions, not agent orchestration — a useful conceptual boundary for engineers validating AI-generated code.
