There are an infinite number of tests that could be performed.
That this test could have been performed does not mean that all possible tests could have been performed.
Which is really what we're talking about here.
Is "able to run 51 days without reboot" a requirement, or not? If not, and it's not a use case, then it shouldn't have been tested for.
Instead, the limited time and resources available should have been spent on more important things.
This just gets back to the issue though - since all this software is locked behind privacy laws we have no visibility into how thoroughly this bug was identified. We don't know if there is a test out there confirming that this data corruption occurs after the expected amount of time after each patch.
You mean on the FAA side?
I don't have as much a problem with that. There's always been tension between regulator access and proprietary corporate information. In order to get the former, you have to design a scheme to protect the latter.
