Tests a matrix of options: - local/remote negotiation initiator - 'most' bundle-policy combinations (some combinations will never work) - firefox or chrome browser Across 4 test scenarios: - simple negotiation with default browser streams (or none if gstreamer initiates) - sending a vp8 stream - opening a data channel - sending a message over the data channel for a total of 112 tests!
