GenLayer Test - Testing Framework

Project Summary

GenLayer Testing Suite is a high-performance testing framework built for developing and validating intelligent contracts across the GenLayer ecosystem. Powered by pytest and tightly integrated with GenLayerPY, it enables deterministic and statistical testing of AI-powered smart contracts in both simulated and live blockchain environments.

Technical Overview

🧩 Technology Stack

• Language: Python 3.12 +

• Core Framework: pytest

• Key Dependencies: genlayer-py, colorama, pyyaml, python-dotenv

• Distribution: PyPI (genlayer-test)

• Integrations: GenLayer Studio, Docker environments

🏗️ Architecture Highlights

Bridges traditional testing with AI and blockchain validation through:

1. Contract Factory Pattern – dynamic deployment and interaction layer

2. Transaction Context System – deterministic, validator-aware execution

3. Statistical Analysis Engine – multi-run simulations for LLM contracts

4. Mock LLM System – reproducible tests with predefined responses

5. Pytest Plugin Integration – CLI-native and IDE-friendly workflow

🔑 Key Features & Innovations

1. Intelligent Contract Testing

• End-to-end deployment and interaction for AI-powered smart contracts

• Supports deterministic and probabilistic behaviors

• Fully aligned with GenLayer’s consensus protocols

2. Statistical Analysis Framework

Analyze LLM-based contract reliability with .analyze():

result = contract.process_with_llm(args=["input"]).analyze(
    provider="openai", model="gpt-4o", runs=100
)
print(result.success_rate, result.reliability_score)

Enables multi-run validation, reliability scoring, and edge-case detection.

3. Mock LLM System

• Pattern-based AI response emulation

• Supports exec_prompt, prompt_comparative, and prompt_non_comparative

• Runs entirely offline for CI/CD reproducibility

4. Validator Factory Framework

• Create custom validator sets with provider, stake, and parameter control

• Batch creation and cloning

• Integrated mock validators for testing consensus behavior

5. Multi-Network Flexibility

Pre-configured for:

• localnet (auto-accounts, fast feedback)

• studionet (Studio integration)

• testnet_asimov (public deployments)

• Custom YAML-based networks

6. Advanced Transaction Control

• Custom consensus parameters

• Deterministic timestamps (GenVM datetime)

• Leader-only mode for developer efficiency

🧠 Core Contributions

1. Validator Factory System → architecture & implementation (v0.8.0+)

2. Transaction Context Framework → deterministic execution model

3. Statistical Analysis Engine → non-deterministic contract testing

4. Network Config System → YAML + env-driven multi-network support

5. Assertion Framework → reusable utilities for contract validation
