> The Storm Compatibility tests frequently fail.
> The reason is that they kill the topologies after a certain time interval. That may fail
on CI infrastructure when certain steps are delayed beyond usual. Trying to guarantee progress
by time is inherently problematic:
>   - Waiting too short makes tests unstable
>   - Waiting too long makes tests slow
> The right way to go is letting the program decide when to terminate, for example by throwing
a special {{SuccessException}}.
> Have a look at the Kafka connector tests, they do this a lot and hence run exactly as
short or as long as they need to.
> Here is an example of a failed run: https://s3.amazonaws.com/archive.travis-ci.org/jobs/77499577/log.txt
