Awesome Testing

MockServer is an HTTP(S) mock server and proxy for testing that lets you mock APIs, inspect and modify live traffic, and inject failures. It supports HTTP/1.1, HTTP/2, gRPC, WebSockets, TCP and more on a single port, with additional support for HTTP/3, message brokers, and AI/LLM APIs.

Hercules is the world’s first open-source testing agent, enabling UI, API, Security, Accessibility, and Visual validations – all without code or maintenance. Automate testing effortlessly and let Hercules handle the heavy lifting! ⚡

Continuous Regression Testing for Engineering Teams

AI-powered E2E testing for 10 platforms. 253 MCP tools. Zero config. Works with Claude, Cursor, Windsurf, Copilot. Test Flutter, React Native, iOS, Android, Web, Electron, Tauri, KMP, .NET MAUI — all from natural language.

OrcaReplay — Time travel for AI agents. Record, replay, fork, and debug any agent run with any model. Built by the OrcaRouter.ai team.

Hardware testing for the software world. Real or virtual, local or remote, human, automated or agentic.

Discover, mask, and verify sensitive data in SQL databases — an auditable scan → mask → validate workflow for safe database copies.

An agent-native QA CLI for web pages. Deterministic, no tests to write, no LLM.

Optics Framework is a powerful, extensible no code test automation framework designed for vision powered, data-driven testing and production app synthetic monitoring.

Test harness for voice agents. Import from Retell, VAPI, Bland, LiveKit. Run autonomous simulations. Evaluate with LLM judges.

AI-Drived end-to-end test platform

The Swagger Coverage Tool is designed to measure API test coverage based on Swagger documentation. It provides automated tracking and reporting of test coverage for APIs, helping ensure that your endpoints and services are well-tested.

Enterprise-grade platform to generate and execute Cypress, Playwright, WebdriverIO, and Appium end-to-end tests from natural language requirements. (Appium is experimental and requires external mobile infrastructure.)

Convert Postman Collection v2.1 JSON into executable pytest test suites

UI Coverage Tool is an innovative, no-overhead solution for tracking and visualizing UI test coverage — directly on your actual application, not static snapshots.

Open-source simulation harness for testing AI agents. Simulate LLM and tool calls to test edge cases, failure paths, and agent logic without live API calls.

Assertions for non-deterministic AI text. Drop into pytest, get a Trust Score + HTML report. Free-first: rules, local embeddings, then your own LLM judge.

A library that records a program's external inputs — database, HTTP, clock, randomness — and replays them, so any past run can be reproduced and debugged exactly.

Catch silent failures in agent workflows by verifying real system state
