Foxhunt E2E Integration Test Suite

Comprehensive end-to-end integration tests for the Foxhunt HFT Trading System.

🚀 Quick Start

# 1. Start PostgreSQL
docker run -d --name foxhunt-postgres \
  -e POSTGRES_PASSWORD=postgres \
  -e POSTGRES_DB=foxhunt \
  -p 5433:5432 postgres:15

# 2. Run all tests
export DATABASE_URL="postgresql://postgres:postgres@localhost:5433/foxhunt"
./e2e_test_suite.sh

📋 Test Suite Overview

Test	Description	Duration	Status
auth_flow_test.sh	Full authentication flow (JWT + MFA + RBAC)	~12s	✅ Complete
trading_flow_test.sh	Complete trading lifecycle	~8s	✅ Complete
hot_reload_test.sh	Configuration hot-reload (NOTIFY)	~6s	✅ Complete
backtesting_flow_test.sh	Backtesting workflow	TBD	🚧 Future
ml_training_flow_test.sh	ML training workflow	TBD	🚧 Future

🔐 Test 1: Authentication Flow

Tests: Login → JWT → MFA → RBAC → Authenticated Request

What It Validates

• ✅ Trading service accessibility
• ✅ User creation with bcrypt password hashing
• ✅ JWT token generation (HS256 signature)
• ✅ TOTP/MFA infrastructure
• ✅ RBAC permission validation
• ✅ Token expiration and structure
• ✅ Security (invalid credential rejection)
• ✅ Authentication audit trail

Usage

./auth_flow_test.sh

Output

Generates JWT token stored in:

• /tmp/foxhunt_test_token_<PID>
• $FOXHUNT_JWT_TOKEN environment variable

💹 Test 2: Trading Flow

Tests: Order Submission → Risk Checks → Execution → Position Update

What It Validates

• ✅ Order submission validation
• ✅ Pre-trade risk limits (max order size)
• ✅ Order execution simulation
• ✅ Position calculation (quantity + avg price)
• ✅ Complete audit trail
• ✅ SOX compliance validation

Usage

./trading_flow_test.sh

Trade Lifecycle

Order Submit → Risk Check → Execution → Position Update → Audit

🔄 Test 3: Configuration Hot-Reload

Tests: Config Update → PostgreSQL NOTIFY → Service Reload

What It Validates

• ✅ PostgreSQL NOTIFY/LISTEN mechanism
• ✅ Configuration change detection
• ✅ Hot-reload without service restart
• ✅ Change history audit trail
• ✅ Connection stability
• ✅ Performance (< 100ms latency)

Usage

./hot_reload_test.sh

Hot-Reload Flow

UPDATE config → Trigger → NOTIFY → Service → Reload

🎯 Master Test Suite

Script: e2e_test_suite.sh

Orchestrates all tests with:

• Pre-flight checks (database, tools)
• Sequential test execution
• Result aggregation and reporting
• Colored output with progress tracking

Usage

# Run all tests
./e2e_test_suite.sh

# With custom configuration
export TRADING_SERVICE_HOST="localhost"
export TRADING_SERVICE_PORT="50051"
export DATABASE_URL="postgresql://postgres:postgres@localhost:5433/foxhunt"
./e2e_test_suite.sh
