Testing Framework

This monorepo uses Vitest as the primary testing framework, configured for optimal performance and developer experience across all packages and applications.

🚀 Running Tests

Development Commands

# Run all tests across the monorepo
pnpm test:projects

# Watch mode for all tests
pnpm test:projects:watch

# Run tests for a specific package
cd apps/backend/order
pnpm test

# Run tests with coverage
pnpm test -- --coverage

# Open Vitest UI
pnpm test -- --ui

Turborepo Integration

Tests are integrated into the Turborepo pipeline:

{
  "test": {
    "inputs": ["$TURBO_DEFAULT$", "$TURBO_ROOT$/vitest.config.ts"],
    "dependsOn": ["transit", "@repo/vitest#build"],
    "outputs": ["coverage.json"]
  }
}

This ensures:

• Tests run after dependencies are built
• Coverage outputs are cached
• Tests can run in parallel across packages

📊 Coverage Collection

Automated Coverage Collection

The monorepo includes scripts for collecting coverage from all packages:

# Collect coverage reports from all packages
pnpm turbo test

# Collect and merge coverage reports
cd tooling/vitest
pnpm collect-json-reports
pnpm merge-json-reports
pnpm report

Coverage Script (scripts/collect-json-outputs.ts)

Automatically discovers and collects coverage.json files from:

• apps/backend/* - Backend applications
• apps/frontend/* - Frontend applications
