Suppose you have a platform that has a Rails backend / API with all kinds of wonderful Capybara / Cucumber testing magic. On the frontend, you have a standalone javascript app that communicates with your API and its just a Javascript/JQuery app (not a ReactJS, Angular, or any other framework). Now, suppose you want to automate the testing of the app as it is deployed in production on a remote web server…
Does anyone write tests in RSpec/Capybara/Cucumber to test the functionality of the web app in Ruby that can drive the Javascript app at a remote location?
I ask because 1) I am not that proficient in Javascript compared to Rub; 2) My tests on the backend are really complete unless I am confident that the front end is working properly; 3) I want to have continuous testing and notifications of my production environment that can’t be obtained through basic new relic or HTTP get monitoring, you have “play” the app 
So if you use Ruby for remote javascript app testing, I’d like to know and I would LOVE links to resources that describe good recipes for doing just this. Thanks for any advice!
