What is @testing-library/user-event?
The @testing-library/user-event package is a library built on top of @testing-library/dom that simulates user interactions with the DOM. It allows developers to write tests that mimic user behavior in a way that is consistent with how a user would use a web application. This helps ensure that tests are realistic and that the application will work as expected when real users interact with it.

Other packages similar to @testing-library/user-event
selenium-webdriver
Selenium WebDriver is a browser automation library. It is more comprehensive than @testing-library/user-event as it can control the browser at a lower level, but it is also more complex and can be overkill for simple DOM interaction tests.
cypress
Cypress is an end-to-end testing framework that includes a rich set of methods for simulating user events. It is similar to @testing-library/user-event but is designed for full end-to-end testing and offers a complete testing environment with a browser-based UI.
puppeteer
Puppeteer is a Node library which provides a high-level API to control Chrome or Chromium over the DevTools Protocol. It is used for browser automation and can perform actions similar to @testing-library/user-event, but it operates at the browser level and can be used for tasks beyond testing, such as web scraping or generating pre-rendered content.
