How does it prioritize which tests to add first?

The skill uses factors such as business criticality, recent code change frequency, and cyclomatic complexity to recommend tests that offer the highest impact on project reliability.

Can I use this to set up CI/CD quality gates?

Absolutely. The skill provides configuration templates and thresholds for setting global and per-file coverage gates to ensure high standards in your automated pipelines.

What coverage formats does this skill support?

It supports multiple industry-standard formats including LCOV, Cobertura, Istanbul (NYC), Jacoco, and Go coverage outputs.

Does it track coverage over time?

Yes, it maintains historical data to visualize coverage trends across different sprints or project milestones, helping you identify if quality is improving or declining.

Can it identify specific lines of untested code?

Yes, the skill analyzes file-level data to pinpoint specific line ranges and logic branches that are not currently executed by your test suite.

セキュリティとテスト

Analyzes codebase test coverage to identify critical gaps and prioritize quality improvements.

概要

This skill automates the evaluation of software quality by parsing various coverage report formats and identifying untested logic paths. It provides a strategic view of testing health by mapping coverage to business requirements, tracking performance trends over time, and offering actionable recommendations to increase reliability. It is particularly useful for maintaining high standards in complex projects where manual coverage tracking is inefficient, helping teams focus their testing efforts on high-risk areas and business-critical functionality.
