What are the coverage priorities defined in this skill?

The skill prioritizes testing in this order: Happy path, Error cases, Edge cases, and finally Integration tests.

What naming convention does this skill recommend?

It promotes the 'Given/When/Then' structure, where test names read as behavior descriptions (e.g., 'returns 401 when token is expired').

What is the common-testing-k skill?

It is a knowledge-based skill for Claude Code that provides a standardized framework for testing philosophy, naming conventions, and coverage priorities.

How does this skill handle mocking?

It follows a philosophy of minimizing mocks, suggesting they should only be used for external services at system boundaries to ensure tests exercise real code paths.

セキュリティとテスト

Establishes a rigorous testing philosophy focused on behavioral outcomes, coverage priorities, and clean naming conventions.

The common-testing-k skill provides Claude with a specialized knowledge base for writing high-quality software tests. It moves beyond simple syntax to advocate for a behavioral-driven approach where test suites serve as living documentation. By prioritizing actual code paths over mocked abstractions and enforcing a 'Given/When/Then' structure, this skill helps developers avoid common pitfalls like 'tests that lie' or 'tests that waste.' Whether you are defining happy paths or complex edge cases, this skill ensures your testing strategy remains focused on reliability and production-ready behavior.
