In this video we have learned how to see code coverage and reporting using NYC Istanbul tool step by step. 🚀 Welcome to our channel KUMAR Programming! 🎉 🎯 What we’ll cover in this series: We dive into Mocha and Chai, two powerful JavaScript libraries that make unit testing simple and effective using typescript . Learn how to set up a Mocha testing environment, write clean and efficient test cases, and use Chai for assertions to ensure your code works as expected. Whether you're new to testing or just want to improve your workflow, this tutorial has you covered. This series is for the TypeScript and JavaScript developers who wants to write quality code and write unit test cases to maintain quality. In this series you will learn the basic concepts of unit testing - methods, mocking, spying, stubbing functions and testing asynchronous methods and promises as well as API requests using GET and POST methods including code coverage and generate reporting by using nyc Istanbul library. Purpose of this video series is to guide you to start writing the unit test cases after completion of this course. I am pretty much confident that you will be able to write unit test case in typescript and node using mocha and chai. Hope you will learn from this series.
