Mocha is a powerful and flexible open-source JavaScript testing framework designed for testing Node.js applications and browser-based projects. It offers a feature-rich environment for writing, running, and organizing tests with support for various testing styles, including Behavior-Driven Development (BDD) and Test-Driven Development (TDD). Mocha is an essential tool for developers who aim to create reliable, maintainable, and scalable applications with robust testing practices.

Features of Mocha:

• Supports both BDD and TDD, allowing developers to write tests that suit their preferred style of testing.
• Built-in and customizable reporters for detailed test results and efficient debugging.
• Handles async functions, including promises, callbacks, and async/await, making it perfect for modern JavaScript applications.
• Easily integrates with assertion libraries like Chai, Sinon for mocks, and other tools for enhanced testing capabilities.
