Selenium Config

I’m looking for an example of a working circle.yml that gets selenium up and running. Additionally, a test that’s working would be awesome. Barring that, the url that you’re using in the test. I seem to be able to get tests that hit google to work, but not ones that hit my local. Not sure if I need to start a weberver or what, but if someone has a working config that would be very helpful.

Thanks!
