JSDC 2015 - TDD 的開發哲學，以 Node.js 為例
54 likes3,765 views
This document outlines an introduction to test-driven development (TDD) using Node.js. It discusses using Mocha as a test framework, Supertest for APIs, and Should/Chai for assertions. It provides an example of writing a test for a login endpoint, including setting up a test user, making a POST request, and asserting the response is successful. The document recommends using Sinon for mocking sources. It emphasizes TDD principles like writing tests before code, and continuous integration/delivery.
