What are the advantages of Supertest over other testing tools?

Supertest is known for its simplicity and ease of use, especially for testing HTTP servers. It integrates well with Node.js and provides a fluent API for making requests and asserting responses.

Can you give me an example of how to use Supertest?

Sure! Here's a simple example: you can use Supertest to test an Express app like this:

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

request(app)
  .get('/api/users')
  .expect('Content-Type', /json/)
  .expect(200)
  .end((err, res) => {
    if (err) throw err;
    console.log(res.body);
  });

How does Supertest compare to tools like Axios or Fetch?

While Axios and Fetch are primarily used for making HTTP requests, Supertest is specifically designed for testing APIs. It provides built-in assertions and is more suited for testing server responses.

Are there any limitations to using Supertest?

Yes, Supertest is great for testing HTTP servers, but it may not be the best choice for testing non-HTTP services or for more complex testing scenarios that require extensive setup.
