test-coverage

Test coverage analysis automatically parses your coverage reports—lcov, cobertura, or istanbul formats—computes line, branch, function, and statement metrics, and identifies untested code sections. The Skill maps coverage to requirements and generates prioritized recommendations with effort estimates to close gaps.

The Skill processes lcov, cobertura, and istanbul coverage reports. It handles multi-format inputs across codebases and projects, parsing diverse report structures to extract and standardize coverage data for gap analysis.

Yes. The Skill analyzes historical coverage data across time to track trends, identify declining metrics, and spot emerging gaps. This enables monitoring coverage drift and prioritizing improvements based on trajectory.

The Skill maps coverage data to requirements, identifies critical untested paths, and generates prioritized test recommendations ranked by impact gain and effort estimate. This lets you tackle the highest-value gaps first.

The Skill applies to multi-format reports and historical coverage data across multiple codebases and projects, producing gap mappings and recommendations for each. It scales from single-project analysis to portfolio-wide coverage tracking.
