Enhanced Integration Tests with Error Scenarios

Overview

Implements comprehensive integration tests with error handling, performance benchmarking, and robust cleanup mechanisms.

Key Changes

• Error Scenarios: Network failures, invalid inputs, resource constraints, concurrent operations
• Performance Tests: Response time benchmarks, throughput analysis, memory monitoring
• Enhanced Cleanup: Resource isolation and automated cleanup mechanisms
• Test Runner: CLI interface for running specific test suites

New Files

• tests/integration/error-scenarios.test.js - Comprehensive error testing
• tests/integration/performance.test.js - Performance benchmarking
• scripts/run-integration-tests.js - Test runner with setup/cleanup

Enhanced Files

• Enhanced existing integration tests with error handling
• Improved test infrastructure with resource isolation
• Updated Jest configuration for better error reporting

Usage

npm run test:integration:runner structure errors performance

Requirements

✅ Enhanced error scenario testing
✅ Performance benchmarking and monitoring
✅ Resource isolation and cleanup mechanisms
