TDD with Node.js

A project created to learn Test Driven Development (TDD) with Node.js, PostgreSQL, and Knex. We practice a TDD approach called Red/Green/Refactor.

The rules of Red/Green/Refactor (RGR) cycle are simple.

1. Create a unit tests that fails
2. Write production code that makes that test pass.
3. Clean up the mess you just made.

Make it work. Make it right. Make it fast. — Kent Beck's original injunction

What are we creating?

This is a test-first approach to developing a RESTful API.
