> 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.
