   Hello, I see it's more likely ease of tests for flatMapGroupsWithState. We added the utility class in Spark 3.2.0 which allows end users to test the user function of flatMapGroupsWithState with test-purpose GroupState implementation. With this approach, end users don't even need to run the streaming query - they just need to call their user function with the TestGroupState.

   Could you please check whether this utility class fulfills your requirement? Thanks in advance.
