Mocha is a simple and flexible JavaScript testing framework for browser and Node.js applications. Unlike other testing frameworks, it takes a minimalist approach and relies on external libraries for key tasks. It uses Sinon for handling spies, stubs, and mocks, and Chai as the assertion engine. Mocha is extensible through many plugins and can integrate with most test runners.

Jasmine is a BDD testing framework for Node.js projects and other JavaScript applications. The library comes with no external dependencies, so it is simple to use with a low overhead. It's the oldest of the three tools we've covered, having been around since 2010. Jasmine runs on any JavaScript platform and is compatible with other testing libraries.
