Learn to build a full CRUD REST API with Nodejs using TDD in Jest in JavaScript, with unit testing and integration test

Learn how to write a full CRUD REST API with Nodejs, Express and Jest using the test-driven development method!

TDD is becoming more and more of standard, and for good reasons!

With TDD, you can feel more safe and secure that any changes you make are not breaking existing functionality in your applications. Manual tests cannot be sustainable in large applications, or even medium applications. Plus, they're incredibly tedious.

Without TDD... well, you know the story. You try to add functionality while trying to touch the existing code as little as possible, because you don't want to break things unintentionally..

With TDD you won't be scared to make big refactors in your code to clean up messy code, you will know quickly if you've broken any existing functionality!

I'll show you step-by-step how to create a REST API with Express with unit tests and integration tests using the Jest test framework. There's going to be lots of opportunities for you to work on your own and do some exercises as well for optimal learning!
