CompTIA Data+ DA0-002 (V2) Practice Question

Requirement testing is a quality assurance process that validates whether a data product, such as a dashboard or report, meets the specific needs and criteria defined by the stakeholders. In this scenario, the dashboard failed to meet the warehouse manager's stated requirement to track inventory by individual SKU, even though it was technically functional. This indicates a failure to properly test the final product against the initial business requirements. Stress testing evaluates system performance under heavy load, unit testing verifies individual components like calculations in isolation, and data profiling is used to analyze source data to understand its structure and content.
