What is the recommended coverage threshold?

The skill aims for a minimum of 75% for gate enforcement, with a target of 80%+ and excellence at 90%+ for critical packages.

What automation tools are included?

It includes a Coverage Gap Analyzer, a Table-Driven Test Generator, and a Methodology Guide Generator to accelerate the testing lifecycle.

Is this skill only for Go projects?

While natively optimized for Go, the methodology is 89% transferable to languages like Python, Rust, and TypeScript with minor language-specific adjustments.

Does it support CLI application testing?

Yes, it includes specific patterns and templates for capturing stdout/stderr, mocking os.Exit, and testing flag parsing in CLI apps.

How does the Coverage Gap Analyzer improve workflow?

It identifies untested code paths by priority, providing a 186x speedup over manual analysis to reach coverage targets faster.

Security & Testing

Systematizes project testing with coverage-driven gap closure and automated pattern generation to reach 80%+ code coverage.

This skill transforms ad-hoc testing into a systematic, coverage-driven methodology specifically optimized for Go projects, though 89% transferable to languages like Python and Rust. It provides a comprehensive framework of eight documented patterns—including table-driven tests, golden files, and CLI testing—alongside high-speed automation tools that accelerate test generation and coverage analysis by over 180x. Ideal for teams aiming to bridge coverage gaps from 60% to 80%+, it enforces quality gates and provides ready-to-use templates for unit, integration, and CLI testing within the Claude Code environment.
