Testing user interactions is essential to ensure a smooth and flawless user experience. This includes testing how the interface responds to events like clicks, keyboard inputs, and mouse movements. In this chapter, we will learn how to write tests for user interactions using Mocha, Chai, and jsdom.

Preparing for User Interaction Tests

To simulate the browser environment and manage user interactions, we will use jsdom along with Mocha and Chai.

Initial Example: Button Interaction

Let's suppose we have a simple application that displays a message when a button is clicked.
