You can do as many tests as you need using the Test Live button in the app or Broadcaster console (if you are streaming via RTMP). The test link and stream key (if streaming via RTMP) will stay the same for each test.
If you would like to RESET your test event, please follow the instructions here:

The option to create multiple tests is currently only available by request (for business clients only). Please contact us at [email protected].
