Jest JavaScript Testing Framework

Hi everyone. Welcome to Just Getting Started with Jest course of the Test Automation University.

In this course, we'll learn how to create automated tests with Jest.

What is Jest?

Jest is an open source testing framework that has become increasingly popular recently. Initially developed by Facebook, Jest makes it faster and easier to run JavaScript tests by having everything needed included in one framework.

Jest comes with built-in mocking and assertion libraries, which also runs your tests concurrently in parallel, providing faster test execution.

By the end of this course, we should be able to create an execute test in Jest.

I am Toyer Mamoojee, and I will be your instructor for this course on Jest.

Some background info on me…I'm a QA tech lead. I have about 16 years of test automation experience across multiple industries.
