Echo JS 0.11.0

Asynchronicity isn't the problem. I wish I had the time to write a blog post about this, but no, Cypress is not a "Selenium killer" even though the developer experience is definitely an improvement. Unfortunately it's an incremental improvement and not a revolutionary one.

The biggest cons of Cypress is the missing cross-browser support.

I think TestCafe is the better choice

I'm not sure this offers much over any given test framework with mocha+chai+puppeteer (or jasmine2+puppeteer).
