Known Issues and Limitations

⚠️ Test Environment

1. Garbage Collection: Tests require --expose-gc flag for memory leak detection
2. Test Isolation: Some tests may interfere if run in parallel (use --runInBand)
3. Timing Sensitivity: Performance tests may vary based on system load

🔧 Workarounds

# For stable performance tests
node --expose-gc --max-old-space-size=1024 node_modules/.bin/jest \
  tests/integration/phase2/phase2-performance-benchmarks.test.ts \
  --runInBand

# For memory leak tests
node --expose-gc --max-old-space-size=1024 node_modules/.bin/jest \
  tests/integration/phase2/phase2-resource-usage.test.ts \
  --runInBand --detectLeaks
