This document outlines an introduction to test-driven development (TDD) including why it is needed, how to start, and common practices. It discusses using TDD for programming, DevOps, and as a team leader/member. It provides an example of setting up a Node.js project with Mocha and Supertest for TDD including creating tests, mocking, and integrating with continuous integration/delivery pipelines. The document recommends TDD practices from Clean Code and includes additional resources on TDD testimonials.
