The developer company gonna provide us with an entire online TV system including the encoders, wowza streaming servers and web/applications. As usual, we have to perform the acceptance test before receiving it. Do you guys have any suggestion about what test cases we should use for the process? Should I test the system based on performance of particular modules/protocols: RTMP/HDS/HLS/RSTP protocol, module/function that supports sending streams to CDN, module/function that supports multiple adaptive bitrate etc... (any other module/functions should I work with)???
