|
||
## Bottom Line
|
||
- ✅ **1,203 tests passed** (98.36%)
|
||
- ⚠️ **9 tests failed** (0.74%)
|
||
- ℹ️ **11 tests ignored** (0.90%)
|
||
- 🎯 **Exceeds 95% target**

## What Was NOT Tested
|
||
- **data** crate (~50 tests)
|
||
- **trading_engine** crate (~100 tests)
|
||
- **api_gateway** service (~30 tests)
|
||
- **trading_service** (~80 tests)
|
||
- **backtesting_service** (~20 tests)
|
||
- **ml_training_service** (~60 tests)
|
||
|
||
**Reason**: 4GB GPU VRAM constraint + 15-30 min compile time per service
|
||
|
||
---
|
||
|
||
## Next Actions
|
||
1. Fix 3 critical failures (ensemble, DQN, data pipeline)
|
||
2. Re-run ML + integration tests to verify fixes
|
||
3. Schedule 2-hour session to test missing services
|
||
4. Increase coverage from 47% to >60%

|
||
- **GPU**: RTX 3050 Ti (4GB VRAM)
|
||
- **Time**: ~5 minutes
|
||
