How can I use Supertest with Jest for testing my APIs?

You can use Supertest with Jest by first installing both libraries. Then, you can write tests to make HTTP requests to your API.

Can you show me a basic example of a test?

Sure! Here's a simple example:

const request = require('supertest');
const app = require('./app'); // Your Express app

test('GET /api/users', async () => {
  const response = await request(app).get('/api/users');
  expect(response.statusCode).toBe(200);
});

What should I do if I want to test a POST request?

For a POST request, you can use the post method. Here's an example:

test('POST /api/users', async () => {
  const response = await request(app)
    .post('/api/users')
    .send({ name: 'John Doe' });
  expect(response.statusCode).toBe(201);
});

How do I handle authentication in my tests?

You can include authentication tokens in your requests. For example:

const response = await request(app)
  .get('/api/protected')
  .set('Authorization', 'Bearer your_token');
