don't use real hardware when running tests
Tests are trying to use real scanner devices when running.
Tests should not depend on various hardware which can tend to make tests non reproducible and even fail in my case. I have a scanner which is available through network and tests are failing (haven't figure out why yet) when using my scanner. I have to disable it each time I want to run tests which is a bit of a hassle.
IMO tests should not test the hardware but the code and so should not use any possibly defect hardware but instead a 'perfect' test-hardware.
I think that only ironscanner should be used to test and report on scanner.
