Matthias' solution should work in most cases.
In cases where you do not control the source (or the source can never be
finite, like the Kafka source), we often use a trick in the tests, which is
throwing a special type of exception (a SuccessException).
You can catch this exception on env.execute() (it is the nested cause) and
decide that this qualifies the test as successful...
