Looks interesting. Kinda like what Jasmine provides (no DOM required), but allows you to target real browsers.

Except it's not because it's based on JSDOM, which isn't going to simulate any browsers with real accuracy. You're better off biting the bullet and descending into the painful world of Selenium WebDriver testing, sadly.

Are you saying Testling uses jsdom? Because it doesn't, it actually runs in real browsers.
