A lot of the below comments touched on things we do (verifying that changesets are independent, breaking tests into smaller pieces, prioritising changes that are likely to succeed). They add up and the approach does become more complex. We wrote an ACM white paper with more of the details[1]. It’s the many edge cases and several optimisation problems that turn this into an interesting theoretical and practical problem.
