Hey Devs! 👋
In this post, I’ll walk you through my hands-on experience building and testing a small Node.js API server from scratch. As part of an assignment, I explored unit testing, integration testing, API testing using AI (Keploy), and even CI/CD integration with GitHub Actions.
💡 What I Built
I created a simple Task Manager API using:
Node.js + Express
SQLite (via better-sqlite3)
Jest & Supertest for testing
✅ What I Learned
How to write unit tests for app logic with and without mocking the DB.
How to implement integration tests to validate DB interaction.
How to use Keploy for AI-powered API testing using OpenAPI + curl logs.
How to automate tests in a CI/CD pipeline with GitHub Actions.
How automated tools like Keploy save hours of manual test writing!
⚙️ Tech Stack
Backend: Node.js, Express
Database: better-sqlite3
Testing: Jest, Supertest, Keploy
CI/CD: GitHub Actions
📊 Achievements
Over 90% test coverage
Fully working GitHub Actions pipeline for every push

🧠 AI + DevOps is the future, and tools like Keploy make it super easy to reach 100% coverage in minutes — without writing every test manually.
