Ln 634 Test Coverage Auditor

The ln-634-test-coverage-auditor skill enables AI agents to analyze codebases and generate comprehensive reports on testing coverage metrics. It identifies gaps in test suites, suggesting specific areas where additional unit or integration tests are needed to improve reliability.

When to use it

• Before deploying a new feature to production to ensure critical paths are adequately tested.
• During code reviews to verify that pull requests include sufficient test cases for the changed logic.
• When refactoring legacy code to assess if existing tests still cover the updated functionality effectively.
• To establish baseline coverage metrics for a project before initiating a test automation initiative.

Key capabilities

• Scans source code repositories to calculate current test execution percentages.
• Pinpoints specific files and functions with zero or low test coverage.
• Generates actionable recommendations for writing new tests to close identified gaps.
• Integrates seamlessly into CI/CD pipelines for automated quality assurance checks.

Example prompts

• "Analyze the src/auth directory and list all functions currently lacking unit tests."
• "Generate a report comparing test coverage between the main branch and the feature branch for the payment module."
• "Identify critical business logic paths in the checkout flow that have no corresponding integration tests."

Tips & gotchas

Ensure your codebase has at least some existing test infrastructure, as the auditor relies on analyzing current test execution data. For best results, provide context about which parts of the application are considered high-priority for coverage analysis.
