> In some of our integration tests, we want to verify that a Connect worker
> cannot start under poor conditions (such as when its internal topics do not
> yet exist and it is configured to create them with a higher replication
> factor than the number of available brokers, or when its internal topics
> already exist but they do not have the compaction cleanup policy).
> This is currently not possible, and presents a possible gap in testing
> coverage, especially for the test cases
> {{testFailToCreateInternalTopicsWithMoreReplicasThanBrokers}} and
> {{{}testFailToStartWhenInternalTopicsAreNotCompacted{}}}. It'd be nice if we
> could have some way of synchronously awaiting the completion or failure of
> worker startup in our integration tests in order to guarantee that worker
> startup fails under sufficiently adverse conditions.
