system testing: headless browser for Socket.io client tests
This complements the HTTP API stress testing issue https://github.com/decred/dcrdata/issues/913
It's important to test with something as close as possible to production. This means N wallet (e.g. Exodus) connections. Clearly not possible since we don't have code to hack on. But, it is likely that services use the reference socket.io package, so we should test that way, be it in node or a headless browser (rather than via a go client like we can for our API). Note that we have a simple test page that uses the socket.io client library: https://github.com/decred/dcrdata/blob/master/api/insight/test_socket.html
A candidate headless webkit browser with a Go API is webloop:

As suggested by @degeri, headless Chrome or FireFox is a possibility. One avenue for this might be Selenium, which means https://github.com/tebeka/selenium (a Selenium/Webdriver client for Go) might be of use.
Any other viable approaches?
