Metrics used in Software Testing

Metric is a measurement of unit for calculating the Quality of project, process etc.

·         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

·         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.

·         Defects detected in testing:  Defects detected in testing / total system defects

·         Defects detected in production:  Defects detected in production/system size

·         Quality of Testing:  Number of defects found during Testing / (Number of defects found during testing + Number of acceptance defects found after delivery) *100 

·         Effort Productivity:  Test Planning Productivity:  Number of Test cases designed / Actual Effort for Design and Documentation

·         Test Execution Productivity:  Number of Test cycles executed / Actual Effort for testing
