What languages does Test Gap Analyzer support?

It currently supports scanning and analysis for Python, JavaScript, TypeScript, and Go codebases.

Does it integrate with existing coverage tools?

Yes, it can parse .coverage files for Python and coverage.json reports to provide precise gap analysis based on real execution data.

What is the 'Testing Pyramid' mentioned in the skill?

It follows the Amplihack standard: 60% unit tests, 30% integration tests, and 10% end-to-end (E2E) tests to ensure a fast, stable, and maintainable test suite.

How does it prioritize which tests to write first?

It ranks gaps based on risk level, function complexity, and criticality to system reliability, allowing you to focus on the most important functions first.

Can it generate actual test code?

Absolutely. It provides ready-to-use templates for happy paths, error scenarios, and boundary conditions that you can adapt and paste directly into your project.

安全与测试

Identifies untested code paths and generates comprehensive test templates to achieve high-quality coverage following the testing pyramid.

关于

The Test Gap Analyzer is a specialized skill for Claude Code that systematically identifies coverage holes, untested edge cases, and high-risk functions within your codebase. By analyzing source files and existing coverage reports, it provides prioritized, actionable test suggestions and ready-to-use templates for unit, integration, and E2E tests. This skill ensures your testing strategy remains balanced and effective, helping teams transition from low-confidence legacy code to robust, 85%+ coverage environments with minimal manual effort.
