pretense-py
A lightweight stateful property-testing and behavioral contract framework.
Overview
Pretense provides model-based state machine property testing, fuzz generation, and specification parity arbiters.
Key Capabilities
- State Machine Specification: Declare states, transitions, preconditions, and invariants using
@transition. - Fuzz Testing: Deterministic state machine exploration powered by Hypothesis.
- Contract Verification: Parity and behavioral conformance testing between specifications and implementations.
- Command Line Runner: Run state machine suites across packages via
pretense <path>.
Installation
uv pip install pretense-py
Quick Start
import pretense
# Import core pretense primitives
from pretense import transition, TransitionContext, StateMachine
