Does this skill support specific programming languages?

The principles are language-agnostic. The skill provides universal testing logic that Claude adapts to your project's specific syntax, framework, and idioms.

What testing patterns are included?

It includes the AAA (Arrange-Act-Assert) pattern, the test pyramid structure, proper mocking strategies, and test independence requirements.

What are the recommended coverage standards?

The skill targets a minimum of 80% code coverage for production code, prioritizing critical business logic and edge cases over superficial metrics.

How does it help with TDD?

It guides Claude through the Red-Green-Refactor cycle, ensuring a failing test is written before implementation and that the final code is properly cleaned up.

Can it help fix flaky tests?

Yes, it identifies test smells and anti-patterns such as shared state or timing dependencies, offering strategies to make your test suite deterministic.

セキュリティとテスト

Implements language-agnostic testing standards, TDD workflows, and best practices to ensure high-quality, reliable codebases.

Testing Principles & TDD is a foundational skill that equips Claude with a comprehensive framework for architecting and reviewing tests across any programming language. It enforces the Red-Green-Refactor TDD cycle, ensures adherence to the test pyramid (Unit, Integration, E2E), and applies proven design patterns like AAA (Arrange-Act-Assert). By automating quality standards such as 80% coverage and test independence, it helps developers build maintainable, deterministic, and production-ready software suites while identifying common anti-patterns and eliminating flaky tests.
