Testing realtime triggers

I am having problems testing a realtime trigger locally.

That is mainly because the shutdown() function is called immediately after process(). Because of that, the realtime trigger has no time to receive external data.
In contrast, in the platform, shutdown() function is only called when the user manually stops the realtime flow.

It would be useful to be able to specify a duration after which the shutdown function is called (e.g. 5 seconds). This would better mimic the behavior of realtime flows.

This makes sense as a feature.
