  3. Metric? <ul><li>Metric – A quantitative measure of the degree to which a system ,component or process possesses a given attribute. </li></ul><ul><li>Metric generally classified into 2 types. </li></ul><ul><li>- Process Metric </li></ul><ul><li>- Product Metric </li></ul>
  4. Metric? <ul><li>Process Metric </li></ul><ul><li>A metric used to measure the characteristic </li></ul><ul><li>of the methods,techniques and tools employed </li></ul><ul><li>in developing, implementing and maintaining </li></ul><ul><li>the software system </li></ul><ul><li>Product Metric </li></ul><ul><li>A metric used to measure the characteristic of </li></ul><ul><li>the documentation and code. </li></ul>
  5. Testing Metrics.. <ul><li>User Participation </li></ul><ul><li>Use : To find the Involvement of the tester </li></ul><ul><li>= User Participation Test Time Vs </li></ul><ul><li>Total Test Time </li></ul><ul><li>Path Tested </li></ul><ul><li>Use : Extent Of Testing </li></ul><ul><li>= No of Path Tested </li></ul><ul><li>Total No of Paths </li></ul>
  6. Testing Metrics.. <ul><li>Acceptance Criteria Tested </li></ul><ul><li>Use : Extent Of Testing </li></ul><ul><li>= Acceptance Criteria Verified Vs </li></ul><ul><li> Total Acceptance Criteria </li></ul><ul><li>This metric identifies the no of user identified </li></ul><ul><li>criteria that were evaluated during the testing </li></ul><ul><li>process. </li></ul>
  7. Testing Metrics.. <ul><li>Test Cost </li></ul><ul><li>Use : Resources consumed in the testing </li></ul><ul><li>= Test Cost Vs Total System Cost </li></ul><ul><li>This metric identifies the amount of resources </li></ul><ul><li>used in the Testing Process </li></ul>
  8. Testing Metrics.. <ul><li>Cost To Locate Defect </li></ul><ul><li>Use : Resources consumed in the testing </li></ul><ul><li>= Test Cost </li></ul><ul><li> No of Defects located in the Testing </li></ul><ul><li>This metric shows the cost to locate a defect </li></ul>
  9. Testing Metrics.. <ul><li>Detected Production Defect </li></ul><ul><li>Use : Effectiveness of testing </li></ul><ul><li>= No of Defects detected in production </li></ul><ul><li>Application System size </li></ul><ul><li>Test Automation </li></ul><ul><li>Use : Effectiveness of testing </li></ul><ul><li>= Cost of Manual Test Effort </li></ul><ul><li>Total Test Cost </li></ul>
