deterministic-testing

Zero-LLM deterministic jailbreak regression benchmark: runs a repeatable battery of known-pattern attacks against an LLM endpoint and scores refusal/partial/compliance across runs. Catch when a model or prompt update silently got weaker. Single-turn, responsible-use. pip install hermes-jailbench

Deterministic runtime for agent evaluation

KayaDB distributed key-value storage engine

Regression memory for coding agents — seal how your repo behaves, then check over MCP (or in CI) that an edit didn't regress it: pass/drift/regressed/missing. With seal history, bisection, and staleness queries.

Reproduce race conditions in real PostgreSQL application code and keep the failing order as a regression test.

Local-first C# project for deterministic prompt versioning, A/B evaluation, and evidence-based promotion using structured scoring.

Reliability testing for MCP servers: deterministic faults, bounded recovery, and executable regressions.

Direct gives browser agents repeatable app states that open by URL, with your real interface running on fixture data.

Safe Rust metaprogramming and adversarial testing: typed code generation with receipts, proc macros, generated trials, mutation, replay, and reproducible evidence.

Deterministic UI testing framework for TS/JS — canvas-first. Virtual time, scene contracts, model-driven discovery.

A Raft consensus library built from scratch in Rust, with a deterministic network simulator for testing leader election, log replication, and partition recovery.

Record normalized DeepSeek Harness tool results and replay them offline with strict matching and zero tool-body execution.

The deterministic heap groomer for C/C++ memory debugging.

Deterministic, zero-dependency static SAP S/4HANA OData and ERP workflow simulator.

Turn-based political sim where policy decisions ripple through 14 competing factions. Manage legitimacy, navigate crises, and survive your rival across 10 possible endings. Built with React + TypeScript via Claude Code, with deterministic testing and accessibility features.

Deterministic evals for AI agents: skill-gain A/B across 11 models (no LLM judge), plus two zero-API regression suites for skill libraries and content merges.

WordleBench — Deterministic AI Wordle benchmark. Compare 34+ LLMs (GPT-5, Claude 4.5, Gemini, Grok, Llama) head-to-head on accuracy, speed, and cost across 50 standardized words.

Deterministic net.Conn/net.Listener fault injection for Go — the testing/synctest philosophy applied to the network layer.

Reproduce OpenAI Agents SDK runtime bugs without API keys — real Runner, scripted models, verifiable certificates.

Compile native Playwright GUI test scripts before the GUI exists. Run them with zero AI.
