The document discusses the BI testing process design. It covers designing test cases for data validation and accuracy, functional testing, and performance testing. For data validation, test cases validate report data against source data and check for missing, incomplete or inaccurate data. Functional test cases cover testing filtering, sorting, drill-downs and other report interactions. Performance test cases use realistic data loads and monitor response times under increasing user loads to identify performance issues. Automating tests improves coverage, speed, accuracy and reproducibility compared to manual testing.
