Jan Hellar This will be quite tricky as metrics are enabled only on real devices + entire metrics/audit infrastructure needs to be there. I have tried to find if we can execute things in the browser and we can create mocked web based metrics, however problem will be how to send them and measure results. Metrics are usually just pipe without acknowledge from server. I'm happy to apply any suggestions but it is hard for me at the moment to find any way to have tests that make sense and fact that we going to rewrite metrics layer soon will mean that whatever we going to apply it will still need some adjustments.
