Additionally, I would like to ask if there is a test package similar to tracetest for metric? I checked the code and did not find anything similar.

There is metricdatatest. I am changing the test struct used in this PR to use that in #6400

Already prepared for review.

If the unit test coverage requirement is very strict, I can supplement it later.
