Measurement is fundamental to any engineering discipline
- We cannot control what we cannot measure!
- Metrics helps to measure quality
- Serves as dash-board
The main metrices are :size,shedule,defects.In this there are main sub metrices.
Test Coverage = Number of units (KLOC/FP) tested / total size of the system
Test cost (in %) = Cost of testing / total cost *100
Cost to locate defect = Cost of testing / the number of defects located
Defects detected in testing (in %) = Defects detected in testing / total system defects*100
Acceptance criteria tested = Acceptance criteria tested / total acceptance criteria
