cobertura-analysis

Overview

Cobertura is "a free Java tool that calculates the percentage of code accessed by tests" (cobertura-home). Its XML report format - sometimes called coverage-04.dtd after its DTD - became the de-facto JVM coverage interchange and is now emitted by JaCoCo, coverage.py (--xml), Jest's cobertura reporter, Istanbul, gocover-cobertura, .NET's coverlet, and many CI plugins.

This skill covers parsing the canonical Cobertura XML structure (cobertura-dtd), computing per-class deltas, and PR-gating.
