Hi @suneeshtr - in principle it is okay and possible to use any device for testing.
You can test directly on watches which have a Developer Bridge option but often it is simpler to use the Fitbit Studio, OS Simulator for most testing.
For watches without the Developer Bridge [some Versa 2, or the Versa 4 and Sense 2] you can create a project in the Gallery Application Manager and install the item via a private link to the watch.
