18 Claims

1. A method of testing performance of a device-under-test (DUT) during cloud gaming over a live cellular network, comprising:

instrumenting the DUT with at least one instrument app that interacts with a browser on the DUT and captures performance metrics from gaming network traffic;

invoking the browser and the instrument app using a test controller separated from the DUT, causing the browser to connect to a gaming simulation over the live cellular network;

transmitting, to the browser, a segmented gaming image stream, segments playing at varying bit rates and image complexity, while the instrument app causes the browser to transmit artificial gameplay events to a gaming simulation test server; and

capturing (i) performance metrics from the gaming network traffic resulting from the segmented gaming image stream and artificial gameplay events during the segments and (ii) gaming images rendered by the browser during the segmented gaming image stream using the instrument app on the DUT and an analyzer on the gaming simulation test server's side of the live cellular network.
