Practice TDD with Node, Typescript and Jest (checkout kata) – Free Udemy Courses

This is not an actual course, is an exercise showing how to practice Test Driven Development TDD using Node.js Typescript and Jest as a framework library.

How we will work this out is, first, we will present a problem to check out a list of items and calculate the final price, but we would add some spice to it by adding some discounts to some products. Later, we will implement this problem by writing the tests first, starting with the simple functionality and growing our design and our functionality until it matches all the requirements provided.

While we try to find the solution to this problem, we will remain disciplined staying always within the red-green-refactor loop, which will guarantee that we will make it until our final design assuming no risks, working the solution iteratively and in small increments.

This exercise is a sneak preview of the other courses published about getting to know TDD in Node Typescript and Jest and building a REST API in both approaches Outside-In and Inside-out. Students can decide after watching this “course” if they would like to take any of the other three. Do you want to develop software like this? Check this out and get to know this practice!
