How can I test my Node.js application using Supertest and Mocha?

You can use Supertest to test HTTP endpoints in your Node.js application, and Mocha as the test framework. First, install both packages using npm.

What are the steps to set up Supertest and Mocha?

1. Install Supertest and Mocha: npm install supertest mocha --save-dev. 2. Create a test file, e.g., test.js. 3. Write your tests using Supertest to make requests to your app.

Can you show me a simple example of a test?

Sure! Here's a basic example:

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

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