Robert Burke created BEAM-6682:
----------------------------------
Summary: [GoSDK] There should be a combineFn unit tester that
validates lifting.
Key: BEAM-6682
URL: https://issues.apache.org/jira/browse/BEAM-6682
Project: Beam
Issue Type: Improvement
Components: sdk-go
Reporter: Robert Burke
The Go direct runner doesn't handle combiner lifting, which means combiners
aren't validated whether they support lifting correctly or not. It should be
possible for the ptest package to simulate combiner lifting, and actuate the
lifecycle methods, or for the direct runner to be re-written to handle combiner
lifting as a configuration option. This would make it easier to avoid mistakes
and typos when handling lifecycle methods for CombineFns.
