Automated functional testing using selenium and javascript bindings

aka

FUCK FUCK FUCK Driven Development

I found out about cypress this weekend. It seems to be nicer than selenium.

https://www.cypress.io/

Google's puppeteer is also very easy to set up and seems reliable. It only supports Chrome, that might be a show stopper.

webdriver.io is better (IMHO) than webdriver and doesn't require a selenium server. You can plug it directly into the various browser drivers like chromedriver and geckodriver. The only drawback is I could never get it working inside a docker container, something most CI systems will need.
