Power BI report testing tools check that the numbers in Power BI reports and dashboards are right and stay right. They compare report values against the source data, catch changes between report versions (regression testing), and measure how fast reports load. This matters most when reports drive financial or regulatory decisions, or when many reports share one dataset.
