COVERAGE ANALYSIS
================
Files with Good Coverage (>20%): 3 files
Files with Medium Coverage (10-20%): 6 files  
Files with Poor Coverage (5-10%): 6 files
Files with No Coverage (0%): 4 files

RISK ASSESSMENT
===============
🚨 CRITICAL RISKS:
- Database operations untested (data integrity risk)
- File persistence untested (data corruption risk)
- Core utility functions largely untested

⚠️ HIGH RISKS:
- ML feature extraction algorithms untested
- Training pipeline largely untested  
- Broker integrations minimally tested

RECOMMENDATIONS TO ACHIEVE 95% COVERAGE
=======================================
IMMEDIATE ACTIONS (Critical):
1. Add comprehensive tests for storage.rs:
   - Database CRUD operations
   - Transaction handling
   - Connection management
   - Error scenarios

2. Add comprehensive tests for parquet_persistence.rs:
   - File I/O operations  
   - Data compression/decompression
   - Schema validation
   - Large file handling

HIGH PRIORITY (Week 1-2):
3. Expand utils.rs test coverage:
   - Data validation utilities
   - Format conversion functions
   - Mathematical operations
   - String processing

4. Add unified_feature_extractor.rs tests:
   - Feature calculation algorithms
   - Edge cases and boundary conditions
   - Performance edge cases
   - Data type handling

5. Expand training_pipeline.rs tests:
   - Pipeline workflow tests
   - Model training scenarios
   - Error handling
   - Resource management

MEDIUM PRIORITY (Week 3-4):
6. Enhance provider test coverage:
   - Connection handling
   - Data streaming
   - Error recovery
   - Rate limiting

7. Add integration tests:
   - End-to-end data workflows
   - Multi-provider scenarios
   - Failover testing
   - Performance benchmarks

ESTIMATED EFFORT
================
Total additional tests needed: ~150-200 test functions
Estimated development time: 2-3 weeks
Priority order: Critical → High → Medium → Integration

CURRENT STATUS: ❌ DOES NOT MEET 95% COVERAGE TARGET
TARGET STATUS: Achievable with focused effort on critical modules

COMPILATION ISSUES
==================
⚠️ Note: Some coverage analysis was limited due to compilation errors in:
- databento_streaming.rs (syntax error around line 308)
- Core module dependencies

Recommend fixing compilation issues before implementing comprehensive testing.
