Metrics helps mainly to track
- Schedule
- Size/Complexity
- Cost
- Quality
Metrics gives better picture of where we are and what are the necessary steps to be taken to improve the process.
Some of the important Testing Metrics
- Test Case Writing Efficiency = Number of Test cases Written/Time
- Test Case Execution Efficiency = Number of test case Executed/Time
- Test Case Effectiveness = Number of test cases that resulted in logging defects / the total number of test cases
- Defect removal efficiency (DRE) = (Number of Defects Removed / Number of Defects at Start of Process) * 100
- Defect Rejection Ratio = Number of rejected defects/The total number of defects logged * 100
- Test Efficiency Score = Number of defects were leaked to the users /The number of defects reported by the testing team * 100
- Review Efficiency = Number of defects detected /Pages reviewed per day
- Scope Changes = The number of changed items in the test scope/The total number of items * 100
- CFDR (Cost of finding Defect in Review) = Cost Spend in Review/ Number of Review Defect
- CFDT (Cost of finding Defect in Testing) =Cost spending in testing/ Number of Testing Defects
- E.V. (Effort Variance) = Actual Effort/Planned Effort * 100
- S.V. (Schedule Variance) =Actual Number of Days/Plan Number of Days * 100
