What is the impact of data volume and variety on regression testing in ETL?

  • Increased data volume and variety decrease the need for regression testing
  • Increased data volume and variety have no impact on regression testing
  • Increased data volume and variety increase the complexity and scope of regression testing
  • Increased data volume and variety make regression testing unnecessary
The impact of data volume and variety on regression testing in ETL is significant. As data volume and variety increase, the complexity and scope of regression testing also increase. More data and diverse data types introduce additional potential points of failure, requiring thorough testing to ensure the stability and accuracy of the ETL process.
