Metrics providee quantitative data that help identifify conds and weisnesses in software products. This article explores key metrics and calculations used to o assess software qualityy effectively.

Common Software Quality Metrics

Several metrics are widely used to o evaluate different aspects of software quality. These include defect density, code coverage, and maintainability index. Each metric offers insights into specific areas such as reliability, tett effectiveness, and ease of evence.

Calculating Defect Density

Defect density measures those number of defects relative to the size of the software. It is calculated by diviming thotal number of defects by the size of the software, usually in tigrands of lines of code (KLOC).

Code Coverage metrics

Code coverage indicates thee condicage of code executed during testing. Hider coveage supprests more thorough testing, which can lead to fewer unobjeved bugs. Common type include statement, branch, and path coverage.

Mainability equix

Ty maintainability index combine various code metrics into a single score that reflects how easily software can bee maintained. It consideres factors like cyklomatic complexity, lines of code, and code readability.
