OK so far. Perhaps the fact that my degree was maths and my first job was in stochastic simulation makes me happier than some with them:-) > The > purpose of the test suite isn't to emulate the real world where you need a > failure rate. I think we'd need something more sophisticated to emulate the real world. The difficult case is when all resources on a reslist fail at once. > All you need is one resource that has failed, so that you can > test reslist_invalidate. I don't think that's right. My test generates instances where the number of resources drops below the minimum, and we see new resources being correctly generated. A single resource failure won't catch that. There is another issue where the whole thing fails - e.g. talking to a backend that goes down. We need a testcase to ensure it will fail cleanly rather than go into an infinite loop. If you'd like me to attack that one, let me know. -- Nick Kew
