Implement stress testing suite to evaluate NotifyChain's behavior under sustained, high-volume notification traffic. Tests Added: - High-volume concurrent processing (1k, 5k events) - Sustained load over time (10k events stability test) - Burst traffic handling with idle periods - Priority queue behavior under load - Deduplication efficiency with 50% duplicates - Discord notification service under load - Error recovery and retry mechanisms Features: - Comprehensive metrics collection (throughput, latency, memory, CPU) - Benchmark utilities for performance measurement - Automated test runner with JSON report generation - CI integration via GitHub Actions workflow - Detailed documentation and quick start guide - Performance baselines and targets - Reproducible test results Metrics Tracked: - Throughput (events/second) - Latency (min, max, avg, P50, P95, P99) - Memory usage (heap, RSS, deltas) - CPU usage (user, system) - Success/failure rates - Queue metrics CI Integration: - Runs on PRs affecting notification services - Nightly scheduled runs at 2 AM UTC - Manual workflow dispatch support - PR comments with test results summary - Artifact upload with 30-day retention - Performance baseline comparison Files Created: - listener/src/__tests__/stress.test.ts - listener/src/utils/benchmark-utils.ts - listener/src/scripts/run-stress-tests.ts - .github/workflows/stress-tests.yml - listener/STRESS_TESTS_README.md - listener/STRESS_TEST_DOCUMENTATION.md - STRESS_TEST_IMPLEMENTATION_SUMMARY.md Files Modified: - listener/package.json (added test:stress and stress-test scripts) Usage: npm run test:stress # Run stress tests npm run stress-test # Run with report generation npm run stress-test -- --report custom/path/report.json Performance Targets: - Throughput: >100 events/sec - P95 Latency: <100ms - Success Rate: >99% - Memory Growth: <200MB per 10k events Resolves stress test requirements for notification processing system.
