> [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.
