What is Supertest and how can I use it for parallel testing?

Supertest is a popular testing library for HTTP assertions in Node.js. It allows you to test APIs easily. For parallel testing, you can run multiple test cases simultaneously to speed up the testing process.

How do I set up Supertest in my Node.js project?

To set up Supertest, first install it using npm: npm install supertest --save-dev. Then, you can import it in your test files and start writing tests for your API endpoints.

Can you show me an example of a parallel test using Supertest?

Sure! You can use Promise.all to run multiple tests in parallel. Here's a simple example:

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

const tests = [
  () => request(app).get('/api/endpoint1'),
  () => request(app).get('/api/endpoint2'),
];

Promise.all(tests.map(test => test())).then(responses => {
  // handle responses
});
