Yes.

The trick is to have a good abstraction layer reasonably close to the
hardware.  When you run tests on your development ("host") system, you
use an implementation, which emulates the actual hardware, while an
actual deployment of course maps the abstraction layer to the actual
hardware.

If you have an abstraction layer, you can write tests, which verify that
your emulator and the actual hardware behaves in the same way.  Once
you're sure of that, you can use the emulator to perform automated
testing on the host system, so you with some confidence can postpone
testing on the target system.
