We've been having a lot of issues with the UI tests timing out rather often. There are currently only 2 UI tests that are used to test simple JS functionality.
As we'll employ nodejs for various parts of the new style, we're already looking at needing node to develop for 4.x. Therefore, one of the arguments against using something based on node is no longer valid.

To me this really begs the question why we're forcing ourselves to using an awkward and badly working wrapper in PHP when we could also create the tests in node via https://github.com/GoogleChrome/puppeteer.

+1 for the puppeteer
