NexQuant/test/integration/test_all_features.py

"""
Comprehensive Integration Test Suite for Predix
Tests all 13 implemented features to ensure they work correctly.

Usage:
    pytest test/integration/test_all_features.py -v
    pytest test/integration/test_all_features.py --quick  # Skip slow tests
    pytest test/integration/test_all_features.py -k "backtest or database" -v

Features Tested:
    1. Factor Evolution - LLM generates trading factors autonomously
    2. Model Evolution - ML models are automatically improved
    3. Quant Loop (fin_quant) - Main trading loop runs 24/7
    4. Backtesting Engine - IC, Sharpe, Drawdown, Win Rate
    5. Results Database - SQLite with query functions
    6. Risk Management - Correlation, Portfolio Optimization
    7. CLI Dashboard - Rich-based live display
    8. Web Dashboard - Flask API + HTML Frontend
    9. Health Check - Environment validation
    10. Streamlit UI - Alternative Dashboard
    11. LLM Integration - llama.cpp (Qwen3.5-35B)
    12. Embedding - Ollama (nomic-embed-text)
    13. Security Scanning - Bandit Pre-Commit Hook
