Set up Supertest for Integration Testing

[AladinJmila]

Description

Introduce Supertest to perform integration testing of the Node.js backend API. This setup will allow the team to validate request/response behavior across endpoints and ensure that the backend services interact correctly with the database and middleware.

This task is part of the broader CI/CD and quality assurance initiative aimed at simulating enterprise-grade workflows in a lightweight, open-source environment.

Requirements

• Install Supertest and required dependencies
• Configure basic test environment (e.g., test database, environment variables)
• Add a sample integration test for an existing endpoint (e.g., health check or login)
• Document testing conventions and usage in the project README

Notes

• Why Supertest?
  Supertest was selected because:

  • It is a widely adopted tool for testing HTTP endpoints in Node.js applications.
  • It integrates seamlessly with Express and other Node.js frameworks.
  • It is open-source, lightweight, and easy to set up.
  • While Playwright and Cypress are better suited for frontend/browser testing, Supertest is ideal for backend API validation.
  • This tool is commonly used in real-world backend projects, making it a valuable skill for new developers.

• This setup will complement unit testing and prepare the project for CI/CD integration with GitHub Actions.
