Can you explain DRE? Ans. DRE (Defect Removal Efficiency) is a powerful metric used to measure test effectiveness.

We need two inputs for calculating this metric: the number of bugs found during development and the number of defects detected at the end user. But the success of DRE depends on several factors.
