How can I test API routes in Next.js?

You can test API routes in Next.js using tools like Jest and Supertest. Would you like a code example?

Yes, please provide a code example.

Sure! Here's a simple example:

import request from 'supertest';
import app from '../pages/api/your-api-route';

describe('API Route Tests', () => {
  it('should return 200 and data', async () => {
    const response = await request(app).get('/api/your-api-route');
    expect(response.status).toBe(200);
    expect(response.body).toHaveProperty('data');
  });
});

What other tools can I use for testing?

Besides Jest and Supertest, you can also use Cypress for end-to-end testing or Postman for manual API testing.
