Yadda User Guide

Yadda brings true BDD to JavaScript frameworks such as Jasmine, Mocha, QUnit, Nodeunit, WebdriverIO and CasperJS. By true BDD we mean that the ordinary language (e.g. English) steps are mapped to code, as opposed to simply decorating it. This is important because just like comments, the decorative steps such as those used by Jasmine, Mocha and Vows can fall out of date and are a form of duplication.

Yadda's BDD implementation is like Cucumber's in that it maps the ordinary language steps to code. Not only are the steps less likely to go stale, but they also provide a valuable abstraction layer and encourage re-use. You could of course just use CucumberJS, but we find Yadda less invasive and prefer its flexible syntax to Gherkin's. Yadda's conflict resolution is smarter too.
