Jest Testing on Wide Range of Browsers

Jest is a JavaScript testing framework designed primarily for testing React applications, but it works well with any JavaScript-based project. It provides features like test runners, assertion libraries, and built-in mocking capabilities, making it easy to write unit, integration, and end-to-end tests. Jest is known for its simplicity, speed, and powerful tools for ensuring code quality.

Jest and Selenium serve different purposes: Jest excels in unit testing JavaScript code, especially for React, offering speed and simplicity. Selenium is better for end-to-end browser testing, simulating user interactions across different browsers. Both can be used together for a comprehensive testing strategy.

Yes, Jest can be used for UI testing, especially when paired with tools like React Testing Library. It allows you to test the behavior and rendering of UI components, ensuring they work as expected. However, Jest is mainly used for unit testing, so it’s best suited for testing individual components rather than full end-to-end UI tests.

The LambdaTest Selenium Automation Grid allows you to run Jest automation tests on a secure, robust, and scalable JavaScript test execution cloud. With LambdaTest you can run your JavaScript Selenium tests at scale across 3000+ different environments in parallel, resulting in higher test coverage and much shorter build times.
