A first broadcast stream including a first program containing video content is received by an ingest server of a live cluster of servers, wherein the live cluster of servers is deployed for providing streaming media programs to multiple user devices. The first broadcast stream is provided to one or more user devices. A copy of the first broadcast stream is provided to a device under test configured to test new code installed at the device under test via a processing of the first broadcast stream by the new code installed at the device under test. The device under test is a generic computer. Error performance of the device under test is monitored with respect to the installed new code's processing of the first broadcast stream. ## Claims ### Claim 1 A method for code testing in a video streaming network, said method comprising: providing, by one or more processors to one or more user devices, a first broadcast stream comprising a first program containing video content, said first broadcast stream deployed for providing streaming media programs to multiple user devices;
