Data Migration testing will cover which of the following?
-
GUI Testing with the migrated data
-
Data mapping rule document between source and ‘Intermediate ETL databse
-
Both 1 and 2
-
None of the above
Data migration testing validates both the transformation logic (data mapping rules between source and target) and the functional correctness of the application using migrated data. GUI testing ensures the application works correctly with the new data, while mapping rule verification confirms the ETL logic is accurate. Both aspects are essential for complete migration validation.
Data migration testing needs to validate both that the migrated data displays and behaves correctly through the application's GUI, and that the documented mapping rules between the source system and the intermediate/ETL database were correctly applied. Since both aspects are essential to confirming a migration succeeded, 'both' is the more complete answer than either one alone.
