Ortac: Runtime Assertion Checking for OCaml (Tool Paper)

Runtime assertion checking (RAC) is a convenient set of techniques that lets developers abstract away the process verifying correctness their programs by writing formal specifications and automating verification at runtime.In this work, we present ortac, runtime tool for OCaml libraries programs. functional programming language in which idioms rely on an expressive type system, modules, interface abstractions. ortac consumes interfaces annotated with invariants function contracts produces code wrappers same signature check these runtime. It provides flexible framework traditional checking, monitoring misbehaviors without interruptions, automated fuzz testing programs.This paper presents overview features highlights its main design choices.
