Jest Setup (TypeScript)

  1. Install jest, ts-jest, and @types/jest.
  2. jest.config.ts: set preset: 'ts-jest' and testEnvironment: 'node' (or jsdom for UI).
  3. Map path aliases with moduleNameMapper so @/x resolves like your bundler.
  4. Gate CI with coverageThreshold so coverage can't silently regress.
