DW/BI Testing

Data warehousing and Business Intelligence engagements pose a significant threat to organizations that have huge volumes of data. Information accuracy, consistency and reliability, information validation, data loss, reporting inefficiencies and data security are some of the common challenges faced by our clients globally. To address these issues, Virtusa with its strong background in testing DW and BI projects with experience across multiple enterprise clients has developed efficient testing tools and frameworks that provide a strong test platform for every client testing engagement. The primary focus of our DW/BI testing is to ensure competent and perfect database structures, ETL processes, front-end access and BI reports generations processes completely support the client requirements.

At Virtusa, we use a unique, well defined and structured approach to data warehouse testing. Our testing efforts are designed to be executed in parallel with development efforts to eliminate any possible abnormalities or failures across the ETL applications prior to production. Our data warehouse testing methodology is incremental and is designed to accommodate changing data warehouse schema arising from evolving business needs. Our testing efforts occur in multiple stages of the lifecycle that are designed to ensure that key DW goals including data completeness, data transformation, data quality and performance & scalability, are achieved.
