--------------------------------------
Summary: Outputing "finished" when processing is not called in
ParDoTest.TestDoFn leads to unexpected ElementCount
Key: BEAM-2710
URL: https://issues.apache.org/jira/browse/BEAM-2710
Project: Beam
Issue Type: Bug
Components: sdk-java-core
Reporter: Rafael Fernandez
Assignee: Davor Bonaci
Priority: Trivial
While it is legal to call finishBundle even if processElement was not called
(say, when processing an empty input PCollection), it's best to guard against
this case if we're examining correctness of outputs. Specifically, I was
surprised at seeing ElementCount = 1 instead of 0 -- essentially, "finished"
was being counted here.
