# Foxhunt E2E Integration Test Suite

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

## 🚀 Quick Start

```bash
# 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

```bash
./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

```bash
./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

```bash
./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

```bash
# 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
```

## 🔧 Prerequisites

### Required Services

1. **PostgreSQL Database** (port 5433)
   ```bash
   docker run -d --name foxhunt-postgres \
     -e POSTGRES_PASSWORD=postgres \
     -e POSTGRES_DB=foxhunt \
     -p 5433:5432 postgres:15
   ```

2. **Trading Service** (optional for full tests)
   ```bash
   DATABASE_URL=postgresql://postgres:postgres@localhost:5433/foxhunt \
   cargo run --bin trading_service
   ```

### Required Tools

```bash
# Ubuntu/Debian
sudo apt-get install -y \
  postgresql-client \
  bc \
  jq \
  netcat-openbsd \
  oath-toolkit

# Verify
psql --version
bc --version
jq --version
nc -h
oathtool --version
```
