Agent F8: Quick Reference - Regime Endpoint Routing Tests

Date: 2025-10-18 Status: ✅ COMPLETE

---

Quick Start

1. Start Services (3 terminals)

# Terminal 1: Docker infrastructure
docker-compose up -d
docker-compose ps  # Verify PostgreSQL, Redis, Vault running

# Terminal 2: Trading Service
export DATABASE_URL="postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt"
export REDIS_URL="redis://localhost:6379"
cargo run -p trading_service

# Terminal 3: API Gateway
export DATABASE_URL="postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt"
export REDIS_URL="redis://localhost:6379"
export JWT_SECRET="test-secret-must-be-at-least-64-characters-long-for-security-validation-ok-1234567890"
export TRADING_SERVICE_URL="http://localhost:50052"
cargo run -p api_gateway

2. Run All Tests

# Terminal 4: Run tests
cargo test -p api_gateway --test regime_routing_integration_test --ignored -- --nocapture

Troubleshooting

Connection Refused (Port 50051)

# Check API Gateway is running
ps aux | grep api_gateway
lsof -i :50051

# Restart API Gateway
export DATABASE_URL="postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt"
export REDIS_URL="redis://localhost:6379"
export JWT_SECRET="test-secret-must-be-at-least-64-characters-long-for-security-validation-ok-1234567890"
cargo run -p api_gateway &

Trading Service Unavailable

# Check Trading Service is running
ps aux | grep trading_service
lsof -i :50052

# Restart Trading Service
export DATABASE_URL="postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt"
cargo run -p trading_service &

Redis Connection Failed

# Check Redis is running
docker-compose ps | grep redis
redis-cli ping  # Expected: PONG

# Restart Redis
docker-compose restart redis

Database Connection Failed

# Check PostgreSQL is running
docker-compose ps | grep postgres
psql postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt -c "SELECT 1"

# Restart PostgreSQL
docker-compose restart postgres
