Mocha
A feature-rich JavaScript test framework running on Node.js
...Hosted on GitHub. Mocha runs in the browser. Every release of Mocha will have new builds of ./mocha.js and ./mocha.css for use in the browser. Mocha is the most-depended-upon module on npm and Mocha is an independent open-source project, maintained exclusively by volunteers. Given Mocha’s use of function expressions to define suites and test cases, it’s straightforward to generate your tests dynamically. No special syntax is required — plain ol’ JavaScript can be used to achieve functionality similar to “parameterized” tests, which you may have seen in other frameworks.
