How do I write integration tests for my application?

To write integration tests, start by identifying the components that need to interact. What framework are you using?

I'm using Node.js with Express. Any specific tools you recommend?

For Node.js, you can use tools like Mocha or Jest for testing, along with Supertest for HTTP assertions.

Can you give me an example of an integration test using Jest?

Sure! Here's a simple example:

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

test('GET /api/users', async () => {
  const response = await request(app).get('/api/users');
  expect(response.statusCode).toBe(200);
});
