RE: debug app on deviceOpera TV Store
Currently it is not possible as far as I know. You could use the emulator and test on it to some extend. If you want to test on real device,
- Use some remote debugger like jsconsole.com, that can get you the console.log from your TV application. It also facilitate running code onto your application
- Use NewRelic or similar to analyze you application performance and execution time.
- Just keep guessing what would be happening behind, ie, blackbox testing
