describe('User API', () => {
  let authToken;
  let testUser;

  beforeEach(async () => {
    // Create test user
    testUser = await User.create({
      email: 'test@example.com',
      password: 'password123',
      name: 'Test User',
      role: 'user'
    });
    
    // Generate auth token
    authToken = generateToken(testUser);
  });

  describe('GET /api/users/profile', () => {
    test('returns user profile when authenticated', async () => {
      const response = await request(app)
        .get('/api/users/profile')
        .set('Authorization', `Bearer ${authToken}`);
      
      expect(response.status).toBe(200);
      expect(response.body).toHaveProperty('email', 'test@example.com');
      expect(response.body).toHaveProperty('name', 'Test User');

Travel Planning API Testing

This section outlines the testing approach for the Travel Planning API endpoints.

API Endpoints to Test

Endpoint	Method	Description	Test Priority
/api/routes/generate	POST	Generate new route based on user query	High
/api/routes/:id	GET	Get route by ID	High
/api/routes/user/:userId	GET	Get all routes for a user	Medium
/api/routes	POST	Create new route	High

      name: 'Test User'
    });
    
    // Generate auth token
    authToken = generateToken(testUser);
    
    // Mock successful route generation
    routeGenerationService.generateRoute.mockResolvedValue({
      name: 'Paris Adventure',
      destination: 'Paris, France',

          query: '3 days in Paris for art lovers',
          preferences: ['museums', 'history']
        });
      
      expect(response.status).toBe(200);
      expect(response.body).toHaveProperty('name', 'Paris Adventure');
      expect(response.body).toHaveProperty('destination', 'Paris, France');
      expect(response.body.activities).toHaveLength(3);
    });
    
    test('returns 400 for empty query', async () => {
      const response = await request(app)

        .set('Authorization', `Bearer ${authToken}`)
        .send({
          query: '',
          preferences: ['museums', 'history']
        });
      
      expect(response.status).toBe(400);
      expect(response.body).toHaveProperty('message');
    });
    
    test('returns 500 when generation service fails', async () => {
      // Mock service failure
      routeGenerationService.generateRoute.mockRejectedValueOnce(
        new Error('Generation failed')
      );
      
      const response = await request(app)
        .post('/api/routes/generate')
        .set('Authorization', `Bearer ${authToken}`)
        .send({
          query: 'Paris for 3 days',

RouteGenerationService Testing

The RouteGenerationService is responsible for generating travel routes based on user intent. This service requires specialized testing due to its integration with external AI services.

Test Scenarios for RouteGenerationService

1. User Intent Extraction

   • Test extraction of location from natural language query
   • Test extraction of duration from natural language query
   • Test extraction of interests/preferences from natural language query
   • Test handling of unclear queries

2. Route Generation

   • Test creation of complete routes based on extracted intent
   • Test activity selection based on user preferences
   • Test day planning and activity sequencing
   • Test handling of constraints (opening hours, distances)
   • Test optimization of routes for logical flow

3. External API Integration

   • Test mocking of OpenAI responses
   • Test handling of OpenAI rate limits
   • Test mocking of Google Maps location data
   • Test fallback options when APIs fail

Performance Testing

Test Approach

1. Endpoint Load Testing

   • Test each critical endpoint under load
   • Simulate concurrent users
   • Measure response times and error rates
   • Verify resource utilization

2. Batch Processing Testing

   • Test performance with large batches
   • Verify memory management
   • Test error handling during batch processing

3. Database Query Performance

   • Measure query execution times
   • Verify index usage
   • Test with various dataset sizes

Performance Test Tool Configuration

// k6 script example for testing route creation endpoint
import http from 'k6/http';
import { check, sleep } from 'k6';

export const options = {
  stages: [
    { duration: '30s', target: 10 }, // Ramp up to 10 users
    { duration: '1m', target: 10 },  // Stay at 10 users for 1 minute
    { duration: '30s', target: 20 }, // Ramp up to 20 users
    { duration: '1m', target: 20 },  // Stay at 20 users for 1 minute
    { duration: '30s', target: 0 },  // Ramp down to 0 users
  ],
  thresholds: {
    http_req_duration: ['p(95)<500'], // 95% of requests must complete within 500ms
    http_req_failed: ['rate<0.01'],   // Less than 1% of requests can fail
  },
};

export default function() {
  const payload = JSON.stringify({
    name: 'Performance Test Route',
    destination: 'Tokyo',
    duration: 3,
    activities: [
      { name: 'Tokyo Tower', day: 1 },
      { name: 'Shibuya Crossing', day: 2 }
    ]
  });
  
  const params = {
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${__ENV.AUTH_TOKEN}`,
    },
  };
  
  const res = http.post('http://localhost:3000/api/routes', payload, params);
  
  check(res, {
    'status is 201': (r) => r.status === 201,
    'response has id': (r) => r.json('_id') !== undefined,
  });
  
  sleep(1);
}

  • Verify that operations within a transaction are atomic
  • Ensure proper rollback on error
  • Test concurrent transactions for isolation

5. Database Migration Testing

• Priority: Low
• Goal: Test database migration scripts
• Implementation: Create tests following the existing patterns in mock-strategies
• Reference: Use utilities from project.tests.mock-strategies.md
• Tests to Add:
  • Apply migrations to a test database
  • Verify schema changes are applied correctly
  • Test data transformation during migrations
  • Verify backward compatibility where needed

6. Connection Pool Testing

• Priority: Low

  • Verify connection timeout and retry logic

Next Actions

1. First, fix the failing auth.test.js by addressing the route handler issue in inviteCodes.js
2. Extend db-schema.test.js with additional edge case tests following the project test plans
3. Add performance testing methods to existing test files instead of creating a new file
4. Add transaction-related tests to the existing database test files
5. Set up a workflow to test database migrations as they are created
