“Any application that can be written in JavaScript, will eventually be written in JavaScript. - Atwood's Law (Jeff Atwood)”
Jasmine is a behavior-driven development framework for testing JavaScript code. It does not depend on any other JavaScript frameworks. It does not require a DOM. And it has a clean, obvious syntax so that you can easily write tests.
