JavaScript Testing Framework
Jest is a widely used JavaScript testing framework designed to make it easy for you to write and run tests for your JavaScript code. Created and maintained by Meta (formerly Facebook), Jest has quickly become the go-to tool for developers who want a straightforward, reliable, and efficient way to ensure their code works as intended. Whether you are building a small project or a large application, Jest offers a comprehensive set of features that help you maintain code quality and catch bugs early.
One of Jest's standout features is its simple and intuitive syntax. You can write tests in plain JavaScript without needing to learn a complex new language or structure. Jest also comes with built-in test runners, assertion libraries, and mocking capabilities, so you don't have to piece together multiple tools to get started. Its fast and parallel test execution helps you get quick feedback, even on large codebases. Jest also provides clear and colorful output, making it easy to see which tests pass or fail and why.
