We have a "virtual room" at the office that we use to expand our office with our remote teammates. 
It's essentially laptop hooked up to a fancy camera that hosts a Skype meeting. 
In order to simulate a user logging into Skype and joining the meeting, we run a PowerShell script that opens the conference room, 
and simulate CTRL + SHIFT + ENTER to join with video.


$x = New-Object -COM WScript.Shell  
$x.Run('"C:\Program Files (x86)\Microsoft Office\root\Office16\lync.exe" conf:sip:https://join.mydomain.com/meet/myusername/Y5356B19')
sleep -seconds 10
$x.SendKeys("^(+~)")

Update May 2017

Eric Bidelman has documented some of the common workflows possible with headless Chrome over in https://developers.google.com/web/updates/2017/04/headless-chrome.

Update

If you're looking at this in 2016 and beyond, I strongly recommend investigating real headless Chrome: https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md

Windows and Mac users might find using Justin Ribeiro's Docker setup useful here while full support for these platforms is being worked out.
