GAUR Enhanced System - Protecting Goa through Advanced Cyber Patrolling

 AI Patrol System Testing Guide

 Phase 1: Backend System Testing (15 minutes)

 Step 1: Start the Backend System

 cd /Users/christianofernandes/developer/gaur/backend
 conda activate gaur
 ./run.sh
 Expected: All services start successfully, including the new AI components




 # Connect to PostgreSQL and run the AI schema
 psql gaur_police_db
 \i database/ai_patrol_schema.sql
 \q
 Expected: New AI patrol tables created successfully

 Step 3: Test AI Service Basic Functionality

 python test_ai_service_simple.py
 Expected: All tests pass with 90%+ fraud detection accuracy

 Step 4: Test API Endpoints

 # Test AI patrol endpoints (use Swagger UI)
 open http://localhost:8000/docs
 Test these endpoints:
 - GET /api/v1/ai/patrol/services/status - Should return service statuses
 - GET /api/v1/ai/patrol/stats - Should return patrol statistics
 - GET /api/v1/ai/threats/live - Should return live threats (empty initially)

 Phase 2: Frontend Integration Testing (10 minutes)

 Step 5: Start Frontend Dashboard

 cd /Users/christiano/developer/gaur/frontend
 npm run dev
 Expected: Frontend starts on http://localhost:3001

 Step 6: Test Authentication & Navigation

 1. Login with: Badge TEST001, Password testpass123
 2. Navigate to dashboard - should see new "🤖 AI Patrol Hub" button
 3. Click AI Patrol Hub - should load the new AI dashboard

 Step 7: Test AI Patrol Hub Features

 Test each tab:
 - Overview: Service status cards, recent threats
 - Services: Individual service start/stop controls
 - Threats: Live threat feed (empty initially)
 - Analytics: System statistics and metrics

 Phase 3: End-to-End AI Testing (20 minutes)

 Step 8: Test Service Management

 1. In AI Patrol Hub → Services tab
 2. Try starting/stopping individual services
 3. Verify status changes in real-time
 4. Check service logs in backend terminal

 Step 9: Test Fraud Detection

 # Backend terminal - test fraud detection
 cd /Users/christiano/developer/gaur/backend
 python -c "
 import asyncio
 from ai_service.config import AIConfig
 from ai_service.fraud_detector import FraudDetector

 async def test():
     config = AIConfig()
     detector = FraudDetector(config)

     # Test high-risk content
     result = await detector.analyze_content(
         'Cheap hotel in Goa! Pay 50% advance via UPI. Book now! Limited time offer. Contact +91-9876543210',
         'facebook_group',
         'post'
     )

     print(f'Risk Level: {result.risk_level}')
     print(f'Fraud Score: {result.fraud_score:.3f}')
     print(f'Fraud Type: {result.fraud_type}')
     print(f'Keywords: {result.matched_keywords}')

 asyncio.run(test())
 "
 Expected: Should detect as HIGH risk with score >0.5

 Step 10: Test Domain Analysis

 # Test domain analyzer
 python -c "
 import asyncio
 from ai_service.config import AIConfig
 from ai_service.enhanced_domain_analyzer import EnhancedDomainAnalyzer

 async def test():
     config = AIConfig()
     analyzer = EnhancedDomainAnalyzer(config)

     # Test suspicious domain
     result = await analyzer.analyze_domain('cheap-goa-hotels.tk')
     print(f'Domain: {result.domain}')
     print(f'Risk Level: {result.risk_level}')
     print(f'Risk Score: {result.risk_score}')
     print(f'Flagged Reasons: {result.flagged_reasons}')

     # Test legitimate domain
     result2 = await analyzer.analyze_domain('booking.com')
     print(f'\\nLegitimate Domain: {result2.domain}')
     print(f'Risk Level: {result2.risk_level}')
     print(f'Is Legitimate: {result2.is_legitimate}')

 asyncio.run(test())
 "
 Expected:
 - cheap-goa-hotels.tk = HIGH risk (suspicious TLD)
 - booking.com = MINIMAL risk (legitimate domain)

 Phase 4: Integration & Simulation Testing (15 minutes)

 Step 11: Test Scraper Simulation

 1. In AI Patrol Hub, start Facebook and Telegram scrapers
 2. Check backend logs for simulation data generation
 3. Verify threats appear in Live Threats tab
 4. Check database for scraped content

 Step 12: Verify Database Integration

 psql gaur_police_db
 SELECT COUNT(*) FROM scraped_posts;
 SELECT COUNT(*) FROM fraud_alerts;
 SELECT COUNT(*) FROM monitored_groups;
 SELECT * FROM ai_services;
 \q
 Expected: Data appears in all AI patrol tables

 Step 13: Test Permission System

 1. Logout and login as different officer roles
 2. Verify AI Patrol Hub visibility based on permissions
 3. Test service management permissions

 Phase 5: Performance & Error Testing (10 minutes)

 Step 14: Test System Performance

 1. Monitor memory usage in backend terminal
 2. Start multiple services simultaneously
 3. Verify graceful degradation without ML libraries
 4. Test error handling with invalid inputs

 Step 15: Test API Rate Limiting

 1. Make rapid API calls to fraud detection endpoint
 2. Verify rate limiting works properly
 3. Test service restart after errors

 Expected Results Summary

 ✅ Fraud Detection: 90%+ accuracy for scam content
 ✅ Domain Analysis: Proper risk assessment (legitimate vs suspicious)
 ✅ Service Management: Start/stop services from dashboard
 ✅ Real-time Updates: Live threat feed and status changes
 ✅ Database Integration: All data properly stored and retrievable
 ✅ Permission System: RBAC properly integrated
 ✅ Performance: Efficient memory usage and fast response times
 ✅ Error Handling: Graceful degradation and proper error messages

 Troubleshooting Common Issues

 If services won't start: Check conda environment and dependencies
 If frontend won't load: Verify Next.js dependencies installed
 If AI detection fails: Check if running in simulation mode (normal)
 If database errors: Ensure PostgreSQL is running and schema applied
 If permission errors: Verify officer has ai_* permissions in database
