Benefits of DWH/ETL/BI Testing

  • Helps in identifying issues with source information– At the initial stage, the extract-transform-load process can be tested once the data is extracted from the source system. From the beginning, testers can detect the issues. Also, they can find the discrepancies associated with data integration and transformation.
  • Bulk data transfer– For the data warehousing project, ETL testing is necessary to incorporate data migration and data implementation. ETL testing ensures the data has been migrated entirely to a new place.
  • Data loss prevention– Data loss can be prevented by performing ETL testing. It’s an effective method for validating and authenticating information in data warehouse systems. ETL testing ensures that information exchange complies with transformation rules and validity tests.
