Test Metrics
What are different types of metrics used in testing ?
1. User Participation : used to find the involvement of the tester
= Participation test time Vs Total test time
2. Path testing = Number of path tested / total number of paths
3. Acceptance criteria tested = Acceptance criteria verified Vs total Acceptance criteria
This meets identifies the number of user that were evaluated during the testing process
4. Test cost : used to find resources consumed in the testing
= test cost Vs total system cost
This meets identifies the amount of resources used in testing process
5. Cost to locate defect = test cost / number of defects located in the testing
This metrics shows the cost to locate a defect
6. Detected production defect = number of defects detected in production / Application system size
7. Test automation = Cost of manual test effort / Total test cost
8. Schedule variance = (Actual time taken - Planned time) / Planned time * 100
9. Effort variance = (Actual effort - Planned Effort)/Planned effort * 100
10. Test case efficiency = (Total STRs - STRs not mapped)/Total STRs * 100
11. Test case coverage = (Total Test cases - STRs that cannot be mapped to test cases)/ Total Test Cases * 100

What are two types of Metrics ?
Metrics are classified into 2 types :-
1. Process metrics : A metric used to measure the characteristic of the methods, techniques & tools employed in developing implementing & maintaining the software system.
2. Product metrics : A metric used to measure the characteristic of the documentation & code characteristic.

What is Product metrics ?
Product metrics is a metric used to measure the characteristic of the documentation & code characteristic.

What is Process metrics ?
Process metrics is a metric used to measure the characteristic of the methods, techniques & tools employed in developing implementing & maintaining the software system.
