## 🚀 Quick Start

### 1. First Time Setup

```bash
# Activate virtual environment
source .venv/bin/activate

# Install test dependencies
pip install pytest pytest-asyncio pytest-cov httpx

# Frontend dependencies
cd frontend/apps/web && bun install

# Install Playwright (for E2E tests)
bunx playwright install
```

### 2. Run Tests

```bash
# Quick validation (all tests)
pytest tests/unit/mcp/test_http_router.py -v
pytest tests/integration/test_mcp_http_integration.py -v

# Load tests (slower)
pytest tests/load/test_mcp_http_load.py -v -s

# E2E tests
cd frontend/apps/web && bun run test:e2e e2e/mcp-integration.spec.ts
```

### 3. Check Coverage

```bash
pytest tests/unit/mcp tests/integration/test_mcp_http_integration.py \
  --cov=tracertm.mcp --cov-report=html

open htmlcov/index.html
```

## 🎯 Test Execution Paths

### Path 1: Quick Validation (5 minutes)
```bash
# Run unit tests only
pytest tests/unit/mcp/test_http_router.py -v

# Check results
# ✅ All pass → Continue to Path 2
# ❌ Failures → See troubleshooting
```

### Path 2: Full Validation (10 minutes)
```bash
# Run unit + integration tests
pytest tests/unit/mcp tests/integration/test_mcp_http_integration.py -v

# Generate coverage
pytest tests/unit/mcp tests/integration/test_mcp_http_integration.py \
  --cov=tracertm.mcp --cov-report=term

# Check coverage
# ✅ > 80% → Continue to Path 3
# ❌ < 80% → Add more tests
```

### Path 3: Performance Validation (15 minutes)
```bash
# Run load tests
pytest tests/load/test_mcp_http_load.py -v -s

# Check metrics
# ✅ All benchmarks met → Continue to Path 4
# ❌ Benchmarks failed → Optimize
```

### Path 4: End-to-End Validation (1 hour)
```bash
# Run E2E tests
cd frontend/apps/web
bun run test:e2e e2e/mcp-integration.spec.ts

# Check results
# ✅ All pass → Production ready
# ❌ Failures → Fix and rerun
```
