Stop wasting hours manually crafting test cases for your Cursor AI rules. With this extension, you can scaffold, run, and visualize coverage of your `cursorrules` — turning guesswork into a repeatable, automated workflow.
This VS Code extension automates the entire test lifecycle for Cursor rules: generating unit and integration test scaffolds from your existing `.cursorrules` files, executing them against your active IDE context, and producing a rich coverage report that highlights untested patterns. No more blind rule deployments or brittle manual suites — get clear, actionable metrics on what your AI rules actually cover.
## What's Included
- Auto‑scaffolds test skeletons from any `.cursorrules` file — including edge cases for variable substitution, file path patterns, and prompt instructions. - One‑click coverage reporter that visualizes which rules are tested and which are ignored, with per‑file and aggregated percentages. - Native integration with Cursor AI — runs tests inside the same IDE session, using your current workspace and context. - Built‑in support for common test frameworks (Vitest, Jest, Mocha) plus a custom Cursor test runner that simulates AI prompts. - Export coverage data as JSON, HTML, or Markdown — perfect for CI/CD pipelines or sharing with your team.
