## 🎯 K6 Test Scenarios

### Load Test 1: Search Load (High Volume, Public)
- **Endpoint**: `GET /search` & `GET /search/geo`
- **Load Profile**: Ramp 100 → 1000 users over 10 min
- **Success Criteria**: p(95) < 500ms, p(99) < 1000ms
- **Expected**: Public search should handle high concurrent load

### Load Test 2: Authentication (Moderate Load, Gated)
- **Endpoint**: `POST /auth/register`, `POST /auth/login`
- **Load Profile**: Ramp 10 → 100 users
- **Rate Limit**: 5/hour per endpoint
- **Success Criteria**: All requests within rate limit, p(95) < 300ms
- **Expected**: Should gracefully reject over-limit requests

### Load Test 3: Listing Creation (Low Load, Quota Gated)
- **Endpoint**: `POST /listings`
- **Load Profile**: Ramp 5 → 50 users over 5 min
- **Rate Limit**: Quota-gated (per subscription plan)
- **Success Criteria**: 201 for successful creates, 403 for quota exceeded
- **Expected**: Quota guard enforces plan limits

### Load Test 4: Payment Processing (Medium Load, Unthrottled)
- **Endpoint**: `POST /payments`
- **Load Profile**: Ramp 20 → 200 users
- **Dependencies**: Requires authenticated session (JWT)
- **Success Criteria**: p(95) < 1s (external provider latency)
- **Expected**: System handles payment initiation concurrently

### Load Test 5: Payment Webhooks (High Volume, Throttled)
- **Endpoint**: `POST /payments/callback/vnpay`
- **Load Profile**: Sustained 20 requests/min (rate limit)
- **Rate Limit**: 20/min enforced
- **Success Criteria**: All requests process within rate limit
- **Expected**: Webhook queue prevents abuse

## 🔗 Authentication Flow for K6

### Cookie-Based Flow (Recommended)
```javascript
// 1. Register/Login
const loginRes = http.post(`${BASE_URL}/auth/login`, { 
  phone, password 
});
// Cookies: access_token, refresh_token, goodgo_authenticated

// 2. Use cookies for authenticated requests
const profileRes = http.get(`${BASE_URL}/auth/profile`);
// Browser automatically sends cookies

// 3. Refresh when needed
const refreshRes = http.post(`${BASE_URL}/auth/refresh`);
```

### Token-Based Flow (Alternative)
```javascript
// 1. Capture tokens from register/login
const loginRes = http.post(`${BASE_URL}/auth/login`, { phone, password });
const { accessToken, refreshToken } = loginRes.json();

// 2. Use Bearer token header
const params = {
  headers: { Authorization: `Bearer ${accessToken}` }
};
const profileRes = http.get(`${BASE_URL}/auth/profile`, params);

// 3. Refresh access token
const refreshRes = http.post(`${BASE_URL}/auth/refresh`, 
  { refreshToken }, 
  params
);
```

## ⚡ Quick K6 Script Template

```javascript
import http from 'k6/http';
import { check, group, sleep } from 'k6';

const BASE_URL = __ENV.BASE_URL || 'http://localhost:3001/api/v1';

export const options = {
  stages: [
    { duration: '2m', target: 100 },   // Ramp up
    { duration: '5m', target: 100 },   // Sustain
    { duration: '2m', target: 0 },     // Ramp down
  ],
  thresholds: {
    http_req_duration: ['p(95)<500', 'p(99)<1000'],
    http_req_failed: ['rate<0.1'],
  },
};

export default function() {
  group('Search - Public, High Volume', () => {
    const res = http.get(`${BASE_URL}/search?q=chung cu&page=1&perPage=20`);
    check(res, { 'status is 200': (r) => r.status === 200 });
    sleep(1);
  });

  group('Geo Search - Public', () => {
    const res = http.get(`${BASE_URL}/search/geo?lat=10.77&lng=106.70&radiusKm=5&perPage=20`);
    check(res, { 'status is 200': (r) => r.status === 200 });
    sleep(1);
  });
}
```
