Mocha

Mocha is a feature-rich JavaScript testing framework that runs on Node.js and in the browser, enabling developers to write and execute tests efficiently. It supports both Test-Driven Development (TDD) and Behavior-Driven Development (BDD) styles, with flexible reporting and asynchronous testing capabilities. Mocha integrates seamlessly with assertion libraries like Chai and Sinon, making it a go-to choice for validating code functionality. Its customizable test runners, hooks for setup/teardown, and support for various reporters help teams streamline workflows, ensuring robust applications. Ideal for small projects and large-scale apps, Mocha simplifies writing and maintaining tests for JavaScript codebases.
