Description

Should have something like SourceTestUtils but for Splittable DoFn.

Note: SourceTestUtils is focused only on bounded sources, but with SDF we can not assume boundedness.

Imported from Jira [BEAM-2816](https://issues.apache.org/jira/browse/BEAM-2816). Original Jira may contain additional context.
Reported by: jkff.

Research direction

Start by reviewing the existing SourceTestUtils and the original BEAM-2816 Jira context to determine the intended Splittable DoFn tester scope. Done should provide an analogous test utility that does not assume the Splittable DoFn is bounded.
