Re: Firmware Verification Testing & Sample Size

The reason for a sample size is to account for variability. Usability testing has quite a bit of variability through the users.

Software, though, given the same inputs and conditions, is (supposed to be) deterministic and so doing more that one test given the same setup will give the same result. So, yes, a 'sample size' of 1 is appropriate for software tests. Given that you have, in your example, 2 hardware platforms, it is appropriate to test on both platforms.

The point about software verifying itself at startup is outside the scope of formal firmware verification (although, of course, the verification process itself would be verified).
