What are the advantages of Supertest over other testing libraries?

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 basic example:

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 libraries like Axios or Fetch?

While Axios and Fetch are primarily used for making HTTP requests in the browser or Node.js, Supertest is specifically designed for testing HTTP servers. It provides built-in assertions and is more suited for integration testing.

Are there any limitations to using Supertest?

One limitation is that Supertest is focused on testing HTTP endpoints, so it may not be the best choice for unit testing or testing non-HTTP functionalities. Additionally, it requires an Express app or similar to work with.
