Supported configurations of the testing environment and typical use cases.

Immersion level	Device	Sensor	Example use cases
0	real	real	(i) typical usage of the implemented IoT system; (ii) final product testing
1	real	virtual	(i) simulating edge conditions for the IoT system (e.g. extreme temperatures measured by sensors); (ii) testing device capabilities; (iii) choosing appropriate sensors in the design phase
2	virtual	virtual	(i) low-cost simulation of multiple data sources; (ii) testing horizontal scalability of the system; (iii) testing applications working on the edge
