TestDriver AI

What it does

TestDriver AI is a computer-use SDK for end-to-end QA testing. It spawns ephemeral cloud sandboxes running Chrome or desktop environments, then uses vision-based LLMs to interact with UIs the way a human would — clicking, dragging, typing, and asserting visual outcomes. Integrated as a Vitest plugin, it turns natural-language test instructions into reliable, reproducible test runs with video replay.

The interactive MCP App renders inline in your AI client, showing test execution status, video replays, and results without consuming AI context for each frame.

Key features

• Vision-based interaction — Uses screen understanding to click, type, drag, and assert on any UI including iframes, canvas, video, and desktop apps
• Ephemeral cloud sandboxes — Spawns clean Chrome or desktop environments per test; no local setup needed
• Vitest integration — Drop-in plugin for existing Vitest projects with testdriver.assert() and testdriver.find() APIs
• MCP server built-in — testdriverai-mcp binary exposes tools for AI assistants to write and run tests directly
• Video replay & screenshots — Every test run records a video; debug failures by watching the replay
• Broad coverage — Handles third-party web apps, desktop apps, VS Code extensions, OAuth flows, PDF content, file uploads, and more
