Metrics in Software Testing

Metrics for Evaluating Application System Testing:

Metric = Formula

Test overage = 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

Software Testing Standards - CMM

Capability Maturity model

-          It is a five level assessment model

-          Capability Maturity Model (CMM) broadly refers to a process improvement approach that is based on a process model. CMM also refers specifically to the first such model, developed by the Software Engineering Institute (SEI) in the mid-1980s, as well as the family of process models that followed.
