Etienne Chauchot updated BEAM-2606:
-----------------------------------
Description: {{WindowFnTestUtils}} relies only on timeStamps for everything
related to windows assignment in the test helpers. But when creating a custom
{{WindowFn}} (and most likely CustomWindow as well), that {{WindowFn}} might
rely on element value in addition to timestamp to decide the windows that will
be assigned to the element. To be able to test this kind of custom WindowFn, we
need versions of the helper methods in WindowFnTestUtils that allow passing
{{TimeStampedValues}}. (was: {{WindowFnTestUtils}} relies only on timeStamps
for everything related to windows assignment in the test helpers. But when

{{WindowFn}} might rely on element value in addition to timestamp to decide the
