Introduction
Testing is a crucial part of modern JavaScript web development. It ensures that our code is reliable, maintainable, and bug-free. By writing tests, developers can catch issues early in the development process, leading to a smoother and more efficient workflow. There are various types of testing, each serving a specific purpose and offering unique benefits. In this module, we will explore these testing types, understand their importance, and learn how to implement them effectively in our JavaScript projects.
This module will cover everything from setting up a testing environment to writing and maintaining different types of tests. We will use Jest, a popular testing framework, for our examples and delve into concepts such as mocking, stubbing, and code coverage. By the end of this module, you will have a comprehensive understanding of testing in JavaScript web development and be equipped with the knowledge to write robust and maintainable tests for your projects.
