DTM can simulate multiple devices to perform tests at a system level. For example, a real device under test can be placed within a simulated DTM environment to mimic the real system. DTM communicates to the device under test to verify that the communications, network configuration, and data in the system operate correctly.
Simulated system testing has many benefits:
- Reduce costs: the amount of time during Factory Acceptance Testing (FAT) and commissioning because issues are discovered earlier
- Increase test coverage: simulating an entire system enables test cases with greater test coverage that cannot be performed with single device simulators
- Automate tests: system level tests can be highly automated and can be reused across multiple projects
