Work Description: jrmccluskey opened a new pull request, #17813:
URL: https://github.com/apache/beam/pull/17813

least one element, then uses it to ensure that a collection passed to Count()
with a non-zero expected number of elements has at least one element to avoid
an erroneous passing test.

> https://github.com/apache/beam/blob/sdks/v2.39.0/sdks/go/pkg/beam/testing/passert/count.go#L28
> Since it's using a Combine to do the count, it never executes for empty
> Pcollections, and is unable to fail.
> The fix is: when count > 0, plumb the pcollection through as a side input to
> a DoFn that requires the side input to be non-empty. This would catch the
> empty PCollection case.
