The Testing Pyramid: What to Test, Where, and Why It Matters

July 8, 2025 0 Comments

The Testing Pyramid is a widely adopted strategy that helps teams design scalable, reliable, and maintainable test suites. As systems grow in complexity, so does the need for clear testing boundaries. The pyramid has evolved to include not just unit and end-to-end tests, but also component, functional, integration, and contract tests.

This post breaks down each layer, explains how it fits into a modern development workflow, and uses a car manufacturing analogy to make it all easier to understand.

Kubernetes for Production: What You Need to Know to Get Started

July 1, 2025 0 Comments

Kubernetes has become the industry-standard platform for deploying and managing containerized applications. Its popularity is well-earned, offering capabilities like self-healing, automated scaling, and zero-downtime deployments. But many developers hit a wall when moving from sandbox environments to real-world production setups. This post aims to simplify that jump by breaking down what Kubernetes is, how to use it, and the essential hardware and configuration needed for a reliable production deployment.

RAID: Why Everyone Should Care?

June 17, 2025 0 Comments

RAID, or Redundant Array of Independent Disks, is a core technology that powers everything from personal NAS drives to enterprise-grade data centers. It enables you to combine multiple physical hard drives into a single system that improves performance, enhances data redundancy, or balances both. This blog post breaks down what RAID is, how the most common RAID levels work, and what their strengths and trade-offs are. Whether you are setting up your first home server or architecting high-availability infrastructure, understanding RAID is essential.

Takeaways on ChatGPT Codex

June 10, 2025 0 Comments

This article explores how software developers can integrate ChatGPT Codex into their development workflows, from initial code generation to pull request creation. Codex is OpenAI’s code-focused large language model, capable of reading and writing code, generating test cases, and interacting with GitHub repositories. We explain how to get the most out of Codex by combining it with unit tests and test-driven development (TDD), ensuring reliable and verifiable results. Drawing on real-world advice from Simon Willison, we emphasize why automated testing is not just a complement but a critical enabler of safe and effective AI-assisted software engineering.
