Agent 10.17: ML E2E Tests - Quick Reference

Status: ✅ RED PHASE COMPLETE File: services/trading_service/tests/ml_integration_e2e_test.rs Tests: 9 comprehensive E2E tests (577 lines)

---

🚀 Quick Start

Run Tests (After GREEN Phase)

# All ML E2E tests
cargo test -p trading_service ml_integration_e2e_test --lib

# Single test
cargo test -p trading_service test_e2e_ml_trading_pipeline

# With output
cargo test -p trading_service ml_integration_e2e_test -- --nocapture

Before Running Tests

# Start PostgreSQL
docker-compose up -d postgres

# Unset SQLX offline mode
unset SQLX_OFFLINE

---

🎯 TDD Status

✅ RED Phase (Complete)

• All 9 tests have #[ignore] attribute
• Tests WILL FAIL when run
• Test infrastructure complete

⏳ GREEN Phase (Next)

Step-by-Step:

1. Remove #[ignore] from Test 1
2. Run: cargo test test_e2e_ml_trading_pipeline
3. Watch it fail (RED)
4. Implement minimal code to pass
5. Rerun test → GREEN
6. Repeat for Tests 2-9

⏳ REFACTOR Phase (Final)

• Extract common patterns
• Improve code quality
• Add documentation

---

🐛 Known Issues

Pre-Existing (Not Test-Related)

1. SQLX Offline Mode: 10 queries need cache
2. ML Inference: Mamba2Model not exported
3. Ensemble: Missing create_ppo_wrapper_with_id, create_tft_wrapper_with_id

Resolution: Run tests with database connection (unset SQLX_OFFLINE)

---

📊 Coverage

Pipeline Flow

✅ Data loading (50 OHLCV bars) ✅ Feature extraction (26 features) ✅ ML prediction (ensemble) ✅ Order execution (paper trading) ✅ Database persistence (ml_predictions) ✅ Outcome tracking (P&L) ✅ Performance metrics (accuracy, Sharpe)

Models Tested

✅ DQN (Deep Q-Network) ✅ PPO (Proximal Policy Optimization) ✅ MAMBA2 (State Space Model) ✅ TFT (Temporal Fusion Transformer)

Scenarios Covered

✅ High confidence trading (>0.8) ✅ Low confidence fallback (<0.6) ✅ Model disagreement handling ✅ Multi-symbol trading (ES, NQ, ZN) ✅ Risk limit enforcement ✅ Position sizing by confidence

🎉 Success Metrics

Test Quality

• Lines: 577 (comprehensive)
• Tests: 9 (E2E coverage)
• Helpers: 6 (reusable infrastructure)
• Assertions: 30+ (thorough validation)

TDD Compliance

• RED first: ✅ All tests fail
• No premature code: ✅ Only helpers
• Clear assertions: ✅ Every behavior tested
• GREEN roadmap: ✅ Implementation plan defined

📖 Next Actions

1. Resolve SQLX: unset SQLX_OFFLINE
2. Start GREEN: Remove #[ignore] from Test 1
3. Implement: Minimal code to pass
4. Iterate: Tests 2-9
5. Refactor: Code quality pass
