Next Steps: Property-Based Testing (PFORGE-3002)

Priority 1: Property-Based Testing Implementation

Ticket: PFORGE-3002 - Property-Based Testing with Proptest Estimate: 4 hours Status: 📋 Ready to Start

Implementation Plan

  1. Setup Proptest Infrastructure (30 min)

    # Add proptest dependency
cargo add proptest --dev

# Create property test module
mkdir -p tests/property
touch tests/property/config_properties.rs
touch tests/property/handler_properties.rs
touch tests/property/validation_properties.rs

  2. Configuration Roundtrip Properties (1 hour)

    • Property: YAML → Config → YAML produces valid config
    • Property: All valid configs can be serialized and deserialized
    • Property: Tool name uniqueness is preserved across transformations
    • Target: 10,000+ test cases per property

  3. Handler Invariants (1.5 hours)

    • Property: Handler dispatch always returns valid JSON
    • Property: Handler errors map correctly to Error types
    • Property: Registry lookup is consistent (same input → same handler)
    • Property: Schema generation is deterministic

  4. Parameter Validation Properties (1 hour)

    • Property: Required fields always validated
    • Property: Type coercion is consistent
    • Property: Invalid JSON never panics
    • Property: Validation errors are recoverable

  5. Integration with CI (30 min)

    • Add make test-property to CI pipeline
    • Configure proptest for deterministic runs
    • Set failure persistence for reproducibility

Success Criteria

  • ✅ At least 12 property-based tests implemented
  • ✅ 10,000+ test cases per property (configurable)
  • ✅ All properties pass consistently
  • ✅ Property failures are reproducible
  • ✅ Integration with make test and CI/CD
  • ✅ Documentation with examples

Benefits

  • Catch edge cases: Automated generation of test inputs
  • Confidence: 10,000+ test cases vs manual testing
  • Regression prevention: Properties prevent entire classes of bugs
  • Documentation: Properties describe system invariants
