If your production SQL server and test SQL server can talk, you could just do in with a SQL insert statement.
first run the following on your test server:
Execute sp_addlinkedserver PRODUCTION_SERVER_NAME
Then just create the insert statement:
INSERT INTO [PRODUCTION_SERVER_NAME].DATABASE_NAME.dbo.TABLE_NAME (Names_of_Columns_to_be_inserted)
SELECT Names_of_Columns_to_be_inserted
FROM TABLE_NAME
