How Mocha does DOM testing without phantoms

Question

It seems I can do DOM tests using Mocha.

I suggested that I need a headless browser like PhantomJS.

What are the benefits of using PhantomJS with Mocha? (I use Yoman.)

Answer 1

You don't need a dumb browser to run DOM tests with Mocha. A package like jsdom provides a lot of what is needed to conduct DOM testing without using a browser without a headset or not. For example, we used it for testing code that processes the DOM tree.
