Luke Cwik updated BEAM-3750:
----------------------------
Priority: Minor (was: Major)
> Integration test will fail when use TestPipeline.convertToArgs in some
> special cases
> ------------------------------------------------------------------------------------
>
> Key: BEAM-3750
> URL: https://issues.apache.org/jira/browse/BEAM-3750
> Project: Beam
> Issue Type: Bug
> Components: testing
> Reporter: Mark Liu
> Assignee: Mark Liu
> Priority: Minor
> Fix For: Not applicable
>
> Time Spent: 2h
> Remaining Estimate: 0h
>
> ITs(Integration Tests) are using {{TestPipeline.convertToArgs}} to convert
> well-defined options to list of pipeline-recognizable arguments and pass them
> to pipeline main function. A example use case is
> {{WordCountIT}}([https://github.com/apache/beam/blob/master/examples/java/src/test/java/org/apache/beam/examples/WordCountIT.java#L70]).
> However, incorrect format will be generated by this function if the option
> that we want to convert has attribute type {{List}}.
> Ideally, we want to get rid of this complicated conversion step in testing
> which can avoid more problematic cases, but also make integration test better
> understandable.
> Some discussions happened in [https://github.com/apache/beam/pull/4346.] One
> possible approach is to extract part of pipeline code so that integration
> test can reference directly.
