🚀 Running Tests

Quick Start

# Run all tests
npm test

# Run with coverage
npm run test:coverage

# Run specific suite
npm test -- tests/compliance
npm test -- tests/security
npm test -- tests/validation

# Run comprehensive test suite
./tests/run-all-tests.sh

Test Environment Setup

1. Create test database:

   createdb dbis_core_test
   

2. Set environment variables:

   export TEST_DATABASE_URL="postgresql://postgres:postgres@localhost:5432/dbis_core_test"
   export NODE_ENV=test
   export JWT_SECRET="test-secret-key"
   

3. Run migrations (if needed):

   DATABASE_URL=$TEST_DATABASE_URL npm run migrate

📈 Test Quality Metrics

Coverage Goals

• Unit Tests: Target >80%
• Integration Tests: Target >70%
• Critical Paths: 100% (Payment workflow, Compliance, Security)

Test Categories

• Functional: ✅ Comprehensive
• Compliance: ✅ Comprehensive
• Security: ✅ Comprehensive
• Performance: ⏳ To be added
• Resilience: ⏳ To be added

⚠️ Important Notes

1. Test Database: Tests require a separate test database
2. Test Isolation: Each test suite cleans up after itself
3. Mocking: External services should be mocked in unit tests
4. Test Data: Use TestHelpers for consistent test data creation

🎉 Achievements

• ✅ Comprehensive test coverage for critical paths
• ✅ Compliance testing framework in place
• ✅ Security testing comprehensive
• ✅ Validation testing complete
• ✅ Test infrastructure and utilities established
• ✅ Documentation and guides created
