Explore Jest Testing—a simple tool to make sure your JavaScript code is bug-free!
Jest is a tool for testing JavaScript code. It’s easy to use, created by Meta, and helps you catch mistakes before they become problems.
Jest requires no setup, allowing you to start testing immediately. It offers snapshot testing to track changes and code coverage reports to show what’s tested.
To get started, first, ensure Node.js and npm are installed. Next, create a project and add Jest. Finally, configure Jest by adding a simple script to your project.
Create a test file, write a basic test, and run it. Jest helps you see if your code works as it should in a straightforward way!
Jest also simplifies testing asynchronous code, mocking functions and data, and running tests in various environments.
Using Jest with Selenium allows you to check your website's appearance across different browsers, achieve faster test results, and enjoy an easy setup and integration.
In the U.S., JavaScript developers using Jest can earn around $104,948 per year. Knowing Jest can boost your career and salary prospects!
