Test Matrics:
Measurement is fundamental to any engineering discipline.
Why Metrics?
- We cannot control what we cannot measure!
- Metrics helps to measure quality.
- Serves as dash-board.
The main metrics are: size, shedule, and defects.
In this there are main sub metrics.
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.
