Metrics for Evaluating system testing

[Me] :- Guruji, what are the metrics for evaluating system testing?

[Guruji]:-  Well to start off,

Metric = Formula
Test Coverage = Number of units (KLOC/FP) tested / total size of the system. (LOC represents Lines of Code)
Number of tests per unit size = Number of test cases per KLOC/FP (LOC represents Lines of Code).
Acceptance criteria tested = Acceptance criteria tested / total acceptance criteria
Defects per size = Defects detected / system size
Test cost (in %) = Cost of testing / total cost *100
Cost to locate defect = Cost of testing / the number of defects located
Achieving Budget = Actual cost of testing / Budgeted cost of testing
Defects detected in testing = Defects detected in testing / total system defects
Defects detected in production = Defects detected in production/system size
Quality of Testing = No of defects found during Testing/(No of defects found during testing + No of acceptance defects found after delivery) *100
Effectiveness of testing to business = Loss due to problems / total resources processed by the system.
System complaints = Number of third party complaints / number of transactions processed
Scale of Ten = Assessment of testing by giving rating in scale of 1 to 10
Source Code Analysis = Number of source code statements changed / total number of tests.
Effort Productivity = Test Planning Productivity = No of Test cases designed / Actual Effort for Design and Documentation
Test Execution Productivity = No of Test cycles executed / Actual Effort for testing
