testsense

AI-powered test gap analysis for TypeScript codebases.

Find what you're not testing — before it finds you.

---

AI writes code. AI writes tests. But those tests only confirm what the code does — not what your product should do. testsense closes that gap.

It analyzes your codebase, reads your existing tests, and tells you the most important flows you're not testing — with generated Playwright stubs for the top findings.

Quick start

npx testsense analyze

How it works

1. Parses your codebase — maps pages, API routes, components, and hooks using TypeScript AST analysis
2. Reads your existing tests — builds a coverage map of what's already tested
3. Finds what's missing — uses Claude to identify the most critical untested flows and why they matter

Configuration

Create a testsense.config.ts at your project root:

import { defineConfig } from 'testsense'

export default defineConfig({
  src: './src',
  tests: './tests',
  framework: 'playwright',
})

Set your API key:

export ANTHROPIC_API_KEY=your_key_here

Output formats

npx testsense analyze                    # Terminal output (default)
npx testsense analyze --output json      # JSON (for CI integration)
npx testsense analyze --output markdown  # Markdown (for PR comments)
npx testsense analyze --top 5            # Show top 5 gaps (default: 3)
npx testsense analyze --focus checkout   # Focus on a specific flow

Roadmap

• Gap analysis CLI
• GitHub Action — PR-triggered analysis with comment output
• MCP server — test intelligence in Claude Code / Cursor / Windsurf
• Cloud dashboard — team analytics, historical trends, Linear/Jira integration
