概要
This skill acts as both an autonomous test author and a specialized advisor for Go development, implementing a robust testing philosophy that prioritizes real implementations over mocks. It enforces the 'test only public API' principle using the pkg_test pattern and provides structured workflows for unit, integration, and system testing. By leveraging in-memory dependencies and reusable test infrastructure, it ensures high coverage and fast execution without the need for external tools like Docker, making it ideal for maintaining high-quality, maintainable Go codebases.
