We run Karma and Protractor Angular tests from a Jenkins continuous integration (CI) server hosted on AWS. Those two frameworks allow the browser to be run remotely in e.g. https://www.browserstack.com so we can run the tests across a large number of browsers and browser versions. (And a recording of the screen is kept too which makes the debugging of failed UI tests much, much easier.)
Ideally we would like to run Lightning Test Service (LTS) in the same way. The only snippet of relevant information we've found is https://github.com/forcedotcom/LightningTestingService/issues/46 which AFAIK is aiming to run "Headless Chrome" locally. And that requires what looks like some poorly documented setup.
Any suggestions on how to setup a configuration to a remote instance of Selenium such as BrowserStack's offering?
