Your code is a testament to your skills as a developer. No matter what language you use, your code should be clean, elegant, and uncluttered? With test-driven development (TDD), you'll write better code--code that's easy to understand, retains its elegance, and works for years to come.

This indispensable guide will show you how TDD works in three different languages: Go, JavaScript, and Python. With Learning Test-Driven Development at your side, you'll be able to:


Tame domain complexity using a divide-and-conquer approach
Understand how TDD works across languages, testing frameworks, and domain concepts
See how TDD enables continuous integration and continuous delivery
Support refactoring and redesign with TDD
Set up a continuous integration environment with the unit tests produced during TDD
Write clean, uncluttered code using TDD in Go, JavaScript, and Python
