- 5. Testing Metrics.. User Participation Use : To find the Involvement of the tester = User Participation Test Time Vs Total Test Time Path Tested Use : Extent Of Testing = No of Path Tested Total No of Paths
- 6. Testing Metrics.. Acceptance Criteria Tested Use : Extent Of Testing = Acceptance Criteria Verified Vs Total Acceptance Criteria This metric identifies the no of user identified criteria that were evaluated during the testing process.
- 7. Testing Metrics.. Test Cost Use : Resources consumed in the testing = Test Cost Vs Total System Cost This metric identifies the amount of resources used in the Testing Process
- 8. Testing Metrics.. Cost To Locate Defect Use : Resources consumed in the testing = Test Cost No of Defects located in the Testing This metric shows the cost to locate a defect
- 9. Testing Metrics.. Detected Production Defect Use : Effectiveness of testing = No of Defects detected in production Application System size Test Automation Use : Effectiveness of testing = Cost of Manual Test Effort Total Test Cost
