Thanks -- that's very clarifying! But isn't this circular? The lack of bugs is used as evidence of the effectiveness of the testing approach, but the testing

  Yeah but if your software is running in an environment that controls for a lot of non-determinism and can simulate various kinds of failures and degradations at varying rates, and do it all in accelerated time and your software is still working correctly; I think it’d be somewhat reasonable to assert that maybe the testing setup has done a pretty good job.

    Agreed, the approach sounds very interesting and I can see how it could be very effective! I'd love to try it on my own stuff. That's why it's so surprising (to me) to claim that the approach found nearly every bug in something as complicated as a production distributed database. My career experience tells me (quite strongly) that can't possibly be true.
