[QUALITY] No test suite configured for high-velocity component library

[Shooksie]

Summary

The design-system repository has no test suite configured, despite 28 PRs being merged in the last 7 days.

Details

• No test scripts in package.json
• No Jest, Vitest, or other test runner found
• No test files detected in src/

Risk

With 28 PRs/week, the absence of automated tests creates significant risk of undetected regressions. TypeScript type checking passes, but it does not catch behavior/logic regressions.

Recommended Fix

1. Add Vitest (recommended for component libraries) or Jest:

   npm install --save-dev vitest @testing-library/react @testing-library/jest-dom
   

2. Add a test script to package.json
3. Write unit tests for core components
4. Add test coverage requirements for new PRs (e.g., --coverage in CI)
