Test Execution

Run all export tests:

npm test -- tests/unit/exports tests/integration/exports

Run specific test suite:

npm test -- tests/unit/exports/identity-map.test.ts
npm test -- tests/integration/exports/export-routes.test.ts

Known Issues

1. Some tests may require database setup - ensure TEST_DATABASE_URL is configured
2. Integration tests require test database with proper schema
3. Some tests may timeout if database connection is slow

Next Steps

1. Add E2E tests for complete export workflows
2. Add performance tests for large batch exports
3. Add property-based tests for format edge cases
4. Add tests for export history tracking
5. Add tests for metrics collection
