Does Coverage Analyzer automatically generate tests?

Coverage Analyzer focuses on identifying gaps and prioritizing testing efforts. To automatically generate the missing tests, you should use it in conjunction with a test-generator skill.

Which test runners are supported?

It is designed to work with standard coverage report formats like LCOV and coverage.json, commonly generated by runners like Jest, Vitest, and Istanbul.

Can I use this if I don't have an existing coverage report?

Yes, if no report is found, the skill can perform a file-based analysis to estimate test status and priority based on file naming conventions and code structure.

How does it determine which files are 'Critical'?

It uses a weighted criteria system including business logic markers, import frequency, code complexity, and git change frequency to determine impact.

セキュリティとテスト

Analyzes test coverage metrics and prioritizes testing efforts for critical code paths and untested files.

概要

Coverage Analyzer is a specialized skill for Claude Code designed to audit your project's test health by identifying gaps in test coverage. It evaluates line, branch, and function metrics while intelligently prioritizing untested files based on business logic importance, cyclomatic complexity, and usage frequency. By providing a structured roadmap for improvements and identifying high-risk areas, it helps developers focus their testing efforts where they matter most, ensuring robust and reliable software delivery.
