plausible

Tech stack & purpose

Plausible is a property testing framework for the Lean 4 proof assistant that integrates with Lean's tactic system. The framework allows developers to test logical propositions by generating random test cases and automatically shrinking counterexamples when properties fail to hold. It supports built-in types out of the box and provides a mechanism for users to define custom type instances through `Repr`, `Shrinkable`, and `SampleableExt` typeclass implementations, with special support for deriving `Arbitrary` instances for algebraic data types.
