How do I perform integration testing on my Express apps?

To perform integration testing on your Express apps, you can use testing frameworks like Mocha or Jest along with Supertest.

Can you show me a basic example of using Supertest with Mocha?

Sure! First, install Supertest and Mocha. Then, you can write a test like this:

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);
  });
});

What are some best practices for writing integration tests?

Some best practices include keeping tests isolated, using a test database, and ensuring tests are idempotent.

How can I run these tests automatically in my CI/CD pipeline?

You can integrate your tests into your CI/CD pipeline by adding a step in your configuration file to run the test command, like npm test.
