Use cmp in fullvalue_test.go

[damccorm]

We could probably update the comparison helpers in fullvalue_test.go to use cmp options and Transformers instead which would make things much clearer.

Hi, I am new to this project and willing to contribute.

Could you tell me more about the details? For example, what are comparison helper, cmp options, and transformers?

I looked up the original Jira but couldn't find any information about what they are.

The goal here would be to replace or refactor our helpers (for example

beam/sdks/go/pkg/beam/core/runtime/exec/fullvalue_test.go

Line 155 in 3b9ab77

func equal(a, b FullValue) bool {

) to use the cmp package rather than traversing the whole object and doing reflection equality checks to compare them.
