>                 Key: BEAM-14546
>                 URL: https://issues.apache.org/jira/browse/BEAM-14546
>             Project: Beam
>          Issue Type: Improvement
>          Components: sdk-go
>            Reporter: Robert Burke
>            Priority: P3

> 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.
