How do I use Supertest for testing my APIs?

Supertest is a popular testing library for HTTP servers in Node.js. You can use it to test your APIs by making requests and asserting responses.

Can you show me a basic example of a test using Supertest?

Sure! Here's a simple example:

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

describe('GET /api/users', () => {
  it('should return a list of users', async () => {
    const response = await request(app).get('/api/users');
    expect(response.status).toBe(200);
    expect(response.body).toHaveProperty('users');
  });
});

What assertions can I make with Supertest?

You can assert the status code, response body, headers, and more. For example, you can check if a specific property exists in the response body.
