Working with Legacy Code: Michael Feathers' Approach

Introduction Michael Feathers' "Working Effectively with Legacy Code" provides strategies for improving and maintaining legacy codebases. This article explores key concepts and practical examples from the book. Characterization Tests Characterization tests help understand existing behavior before making changes: describe('LegacyCalculator', () => { test('should calculate

TDD and Performance Testing: Building Fast Applications

Introduction Performance testing is essential for building high-quality applications. This article explores how to incorporate performance testing into your TDD workflow. Response Time Testing // performance.test.js describe('API Performance', () => { test('should respond within 100ms', async () => { const start = performance.now(); await request(app).get(

TDD and Clean Architecture: A Perfect Match

Introduction Test-Driven Development and Clean Architecture complement each other perfectly. This article explores how to combine these practices to create maintainable and testable software. Clean Architecture Principles Clean Architecture provides a way to structure applications with clear boundaries and dependencies: * Independence of frameworks * Testability * Independence of UI * Independence of database

The Red-Green-Refactor Cycle: A Deep Dive

Introduction The Red-Green-Refactor cycle is the heartbeat of Test-Driven Development. This article explores each phase in detail and provides practical examples of how to implement this fundamental TDD practice. The Three Phases Red: Write a Failing Test In this phase, we write a test that defines the behavior we want

TDD Best Practices: Writing Effective Tests

Introduction Writing effective tests is crucial for successful Test-Driven Development. This article explores best practices that will help you write better tests and improve your TDD workflow. Test Structure: The AAA Pattern The Arrange-Act-Assert (AAA) pattern is a fundamental structure for writing clear and maintainable tests: test('should calculate

TDD in Frontend Development: Testing React Components

Introduction Test-Driven Development in frontend development, particularly with React, requires a different approach than backend testing. This article explores how to effectively test React components and frontend logic.

Code Review Process // Example of a good code review comment /** * @review * - Tests cover all edge cases * - Code follows SOLID principles * - Performance considerations

Baby Steps in TDD: The Art of Incremental Development

Introduction Baby Steps is a fundamental concept in Test-Driven Development that emphasizes making small, incremental changes to the codebase. This article explores how to effectively implement Baby Steps in your TDD practice. What are Baby Steps? Baby Steps refer to the practice of making the smallest possible change that could

Pair Programming in TDD: A Symphony of Collaboration

Introduction Pair Programming is a powerful practice that, when combined with Test-Driven Development, creates a highly effective development environment. This article explores how to maximize the benefits of pairing in a TDD context. The Roles in Pair Programming Driver and Navigator In TDD pair programming, the roles are particularly important:

TDD and API Development: Building Robust Endpoints

Introduction Test-Driven Development is crucial for building reliable and maintainable APIs. This article explores how to effectively test API endpoints and ensure they meet their specifications. Endpoint Testing // userApi.test.js import request from 'supertest'; import app from './app'; describe('User API', () => { test(
