We hit a rare issue in the CI run here -- one test,
test_seed_not_provided, failed. This didn't have anything to do with the commit, though -- instead, it's an issue with the test. We callevaluate_experimentwith a small number of samples and -1 overall successes, and this leads to us doing the 'coin flip' to check whether this test experiment might have 'crossed the line'. In this case there's a small (~1%) chance for us to 'fail' the coin flip and get a different result than we normally expect in the test, and that's what happened here.We avoid this in other tests by setting the seed, but this is the one test where we deliberately don't do that and test the behaviour. So, the fix is to make the test deterministic in other ways. This PR helps us bypass the coin flip by making sure the probability is zero in our first call (by logging no samples at all) and then all the required samples at once in the second call.
