Daniel Halperin updated BEAM-987:
---------------------------------
Component/s: testing
runner-direct
> TestStream.advanceWatermarkToInfinity should perhaps also advance processing
> time
> ---------------------------------------------------------------------------------

> Key: BEAM-987

> Project: Beam
> Issue Type: Bug
> Components: runner-direct, testing
> Reporter: Eugene Kirpichov
> Assignee: Thomas Groh
>
> I ran into this when writing a test for Splittable DoFn whose input was a
> TestStream. I constructed a TestStream that didn't call
> advanceProcessingTime, and as a result, the SDF's timers didn't fire and the
> test got stuck.
> I think the meaning of "advanceWatermarkToInfinity" is "don't add any more
> elements to the stream and see what happens eventually", and "eventually"
> includes "eventually in processing time domain", not just in event-time
> domain (watermark).
