Essential Software Testing Metrics: How to Measure Quality and Progress

Workload Deviation : ((Actual workload - Planned workload) / Planned workload) * 100% — measures progress.

Test Execution Rate : (Executed test cases / Total test cases) * 100% — measures test progress.

Test Pass Rate : (Passed test cases / Total test cases) * 100% — reflects development quality.

Requirement (Test Case) Coverage : (Number of requirements with designed test cases / Total requirements) * 100% — evaluates test design quality.

Requirement Pass Rate : (Requirements passed testing / Total requirements) * 100% — indicates progress.

Test Case Hit Rate : (Total defects / Number of test cases) * 100% — assesses test case quality.

Reopen Defect Rate : (Reopened defects / Total defects) * 100% — gauges development quality.

NG Rate : (Verification‑failed defects / Total defects) * 100% — gauges development quality.

Defect Effectiveness Rate : (Effective defects / Total defects) * 100% — measures testing effectiveness.

Defect Fix Rate : (Resolved defects / Total defects) * 100% — measures development efficiency.

Defect Lifecycle : Average time from defect submission to closure — applies to development and testing.

Average Defect Fix Duration : Average time from defect submission to fix — applies to development.

Average Defect Close Duration : Average time from defect fix to closure — applies to testing.

Defect Detection Rate : (Defects found by testers / (Defects found by testers + Defects found by customers)) * 100% — measures test quality.
