Test Metrics & Coverage

What are Test Metrics?

// why we measure testing and what good metrics actually tell you.

Why Test Metrics Are Important

// why testing without metrics creates blind spots and how metrics improve decisions.

Test Coverage — Types Explained

// requirements coverage, code coverage, risk coverage — and how they differ.

Code Coverage vs Test Coverage

// why 100% code coverage does not mean 100% tested.

Process vs Product Metrics

// separating how well testing is running from how healthy the product actually is.

Test Execution Metrics

// pass rate, fail rate, blocked rate — measuring the health of your test run.

Defect Metrics

// defect density, defect arrival rate, age, and leakage — the numbers behind bug management.

Requirement Coverage Metrics

// measuring whether agreed requirements are actually covered by test cases.

Defect Removal Efficiency (DRE)

// how to measure how effective your testing is at catching bugs before production.

Defect Leakage

// how many defects escaped testing and were found in later stages or by real users.

Test Effectiveness & Efficiency

// are your tests finding real bugs? are you finding them fast enough?

Reporting Metrics to Stakeholders

// how to present testing data clearly to managers and non-technical stakeholders.

Defect Density

// relating defect count to product size for fairer quality comparisons.

Test Reporting Dashboard

// bringing the most useful metrics together in one clear view for stakeholders.

Test Summary Report

// how to write a professional test summary report at the end of a testing cycle.

Pitfalls of Test Metrics

// how wrong metrics create bad behavior and push teams in the wrong direction.
