How do I integrate Supertest with Mocha for testing my API?

To integrate Supertest with Mocha, first install both packages using npm. You can do this by running npm install supertest mocha --save-dev.

What is the basic structure of a test using Supertest and Mocha?

A basic test structure would look like this:

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

describe('GET /api', () => {
  it('responds with json', (done) => {
    request(app)
      .get('/api')
      .expect('Content-Type', /json/)
      .expect(200, done);
  });
});

Can I test POST requests with Supertest?

Yes, you can test POST requests. Here's an example:

it('creates a new user', (done) => {
  request(app)
    .post('/api/users')
    .send({ name: 'John', age: 30 })
    .expect(201, done);
});
