Hi Michal,
you need to implement a source which does not terminate. Take a look at the
InifiteSource [1] which does exactly this. That way there won't be a
Long.MAX_VALUE being sent when closing the source operator.

Hi guys,
I have opposite issue :-) I would like to unit test negative behavior
- that the Event Time timer is not fired when no further event arrives
(which would advance the watermarks).
But due to StreamSource firing Long.MAX_VALUE watermark after enclosed
finite FromElementsFunction run method d
Hi Steve,
afaik there is no such thing in Flink. I agree that Flink's testing
utilities should be improved. If you implement such a source, then you
might be able to contribute it back to the community. That would be super
helpful.
Cheers,

Hi Steve,
I think the reason for the different behaviour is due to the way event time
and processing time are implemented.
When you are using event time, watermarks need to travel through the
topology denoting the current event time. When you source terminates, the
system will send a watermark wi
