-----------------------------------------
Summary: Godoc for passert.Sum seems wrong
Key: BEAM-7163
URL: https://issues.apache.org/jira/browse/BEAM-7163
Project: Beam
Issue Type: Improvement
Components: sdk-go
Reporter: Damien Desfontaines
From
[https://godoc.org/github.com/apache/beam/sdks/go/pkg/beam/testing/passert#Sum]:
> Sum validates that the incoming PCollection<int> is a singleton with the
> given value.
Why is there a size argument if the input is supposed to be a singleton?
>From the implementation, it seems that Sum sums all elements from the input
>PCollection (which must be int, apparently?), and checks both the number of
>elements and their sum.
