1) The document discusses testing techniques in business intelligence and data warehousing. It examines how testing has evolved from an ad hoc process to a more systematic discipline.
2) While research has produced many sound testing methods, few have been successfully applied in industry due to a "testing gap" between research and practice. Methods remain time-consuming and implementations are not well-automated.
3) The paper aims to analyze how testing techniques have matured, barriers to their adoption, and how to better transfer methods to industry use. It focuses on theoretical underpinnings of techniques and how they can be developed into systematic methodologies.
