Hello all, I found some test utilities that we use to write unit tests for transforms that read/write to/from BigQuery. These are all the non-(*IT.java/*Test.java) classes in [1].
I believe that users may want to write tests for their own pipelines that may rely on complex DynamicDestination logic (imagine streaming, or side inputs for on-the-fly schema computation, or other tricky issues). I think it makes sense to move these classes to org.apache.beam.io.gcp.bigquery.testing, and publish them in the release. Thoughts? -P.
