Scenario: During an ETL testing project, you discover that the transformed data in the target system doesn't match the expected results. What steps should you take to troubleshoot and resolve this issue?

  • Check data quality issues in the source system
  • Re-run the ETL job with the same configuration
  • Review the ETL mapping and transformations
  • Validate the ETL job logs
When encountering discrepancies between transformed data and expected results in ETL testing, it's crucial to review the ETL mapping and transformations thoroughly. This involves examining the logic implemented in the ETL processes, ensuring correct mappings, and validating the transformations applied to the data. By pinpointing potential issues in the ETL workflow, testers can effectively troubleshoot and resolve the data inconsistency problem.
